Description

Technical Field

[0001] The present invention relates to an apparatus, system and method for separating impurities, particularly liquid and / or solid particles, from a gas stream, especially for use in compensation containers in motor vehicles, particularly electric vehicles, and particularly oil compensation containers. Background Technology

[0002] In motor vehicles, especially pure electric vehicles, coolant is used to maintain the vehicle battery at its optimal operating temperature, such as regulating battery temperature and preventing overheating. Overheating of the battery can shorten its lifespan and cause damage.

[0003] These cooling oils are typically located in reservoirs, such as compensation containers, especially oil compensation containers, through which cooling oil can account for and / or compensate for changes in heat volume and / or pressure caused by temperature fluctuations. The oil compensation container comes into contact with electrical components of the electric vehicle, such as battery components. Therefore, the cooling oil must have insulating properties to, for example, prevent runaway currents that could cause short circuits.

[0004] In addition, it is necessary to maintain the insulating properties of the coolant during vehicle operation (e.g., over long periods) to ensure its functionality and / or longer service life, for example.

[0005] Like other liquids, cooling oil in a compensating container is affected by thermal fluctuations, especially temperature fluctuations, such as those in the range of -30ºC to 80ºC. This causes thermal volume changes within the compensating container, such as due to the expansion and / or compression of the cooling oil. Compensating containers can be used to compensate for volume changes in oil, particularly those caused by thermal factors, located in cooling zones (batteries, motors). These thermal volume changes can, for example, create overpressure (e.g., at high temperatures) and negative pressure (e.g., at low temperatures) in the oil tank. However, such overpressure or negative pressure can be compensated for or balanced by the compensating container to, for example, maintain a constant oil pressure and / or oil volume in the system and prevent damage. The compensating container can be proportionally filled with a gas, such as air. The resulting gas pressure (e.g., overpressure / negative pressure) can be regulated by valves, for example, through exchange with the environment; this can be described as an open system.

[0006] To achieve pressure balance, the compensation container can, for example, be in contact with ambient air through corresponding inlets and outlets, which can allow air to enter and / or exit the compensation container. In this way, the thermal volume change of the oil can be compensated by the compensation container.

[0007] However, the cooling oil used is sensitive to moisture, which can affect its insulating properties. Therefore, the air flowing into the oil compensation container must be free of impurities or contaminants, especially liquid and / or solid particles such as water or moisture; thus, ambient air, for example, must be filtered before flowing in. For this purpose, specialized air filtration systems and devices can be used to protect the cooling oil from contamination and to maintain and ensure its insulating properties over the long term.

[0008] To filter incoming gases (such as ambient air), desiccants capable of absorbing moisture from the ambient air can be used. These desiccants are typically hydrophilic, meaning they have an affinity for water or are "water-loving," and therefore absorb moisture effectively. For example, when exposed to ambient air, a desiccant will react or bind with even the smallest amount of moisture contained in the air within a very short time. The moisture absorption capacity of a desiccant can also be called its desiccant loading capacity, where each desiccant has a predetermined and limited moisture absorption capacity.

[0009] Premature moisture absorption (e.g., before the desiccant reaches its intended location) may reduce its effectiveness. The longer the desiccant is exposed to, for example, ambient air, its moisture load increases and its moisture absorption capacity decreases.

[0010] However, premature loading of desiccant is not always avoidable before intended use, such as by the installation or assembly of the desiccant and / or during the installation or assembly process, in storage, unpacking and / or transportation, as it may sometimes inevitably come into contact with air.

[0011] Even if the desiccant's exposure to ambient air is kept to a minimum, preloading can adversely affect its moisture absorption capacity, thus impacting its effectiveness. This not only jeopardizes the insulation properties of the cooling oil but also compromises the function and / or lifespan of the compensation container, battery cooling, and / or the entire electric vehicle. Summary of the Invention

[0012] The purpose of this invention is to overcome the shortcomings of known prior art, and in particular to provide an improved apparatus or an improved method for reducing impurities in the venting process of a compensation container, especially an oil compensation container, and to provide a corresponding system.

[0013] This objective is achieved through the features of the independent claims. The dependent claims describe preferred embodiments. Other aspects, advantages, and features are set forth in the dependent claims, the specification, and the drawings.

[0014] The present invention relates to an apparatus for separating impurities, particularly liquid and / or solid particles, from a gas stream, especially for compensating containers in motor vehicles, particularly oil compensating containers. The apparatus includes a housing configured to hermetically isolate an adsorbent from its surrounding environment, and the adsorbent is exposed to and exposed to air only during installation, particularly upon reaching the final installation position, or after installation, particularly by pressure action, especially by pressure pulses.

[0015] The present invention relates to a system that can be used in combination with, or conversely with, devices according to aspects and / or embodiments of the invention described herein, for separating impurities, particularly liquid and / or solid particles, from a gas stream, particularly a gas stream from a compensation container in a motor vehicle, particularly an oil compensation container, wherein the system includes devices according to aspects and / or embodiments of the invention described herein and a gas exchange container for attachment to the compensation container.

[0016] The present invention relates to a vehicle, particularly an electric vehicle, especially a pure electric vehicle, equipped with a device and / or a system according to aspects and / or embodiments of the invention described herein.

[0017] The present invention relates to a method for separating impurities, particularly liquid and / or solid particles, from a gas stream, especially for a compensation container in a motor vehicle, particularly an oil compensation container, the method utilizing an apparatus and / or a system according to aspects and / or embodiments of the invention described herein.

[0018] This invention relates to an application of an apparatus and / or system according to aspects and / or embodiments of the invention described herein, for separating impurities from a gas stream, particularly liquid and / or solid particles, the gas stream being used, particularly in electric vehicles, especially pure electric vehicles, and / or in compensation containers, particularly oil compensation containers, in battery cooling systems.

[0019] This invention relates to an adsorbent for use in apparatus and / or system and / or method according to aspects and / or embodiments of the invention described herein.

[0020] Obviously, the system-related design schemes described in the claims and specification are also preferably applicable to the apparatus itself according to the invention (e.g., without needing to be installed in a gas exchange container), and vice versa. The apparatus, system, or method mentioned herein refers to the apparatus, system, or method according to the invention.

[0021] The apparatus according to the invention is used to separate impurities from a gas stream, particularly liquid and / or solid particles, especially in motor vehicles as a compensation container, particularly an oil compensation container.

[0022] Gas flow refers to the continuous, pulsed, or discontinuous movement of gas within a defined space and / or in a specific direction, such as gas flows of different scales or the flow of gas particles moving within a specific area. For example, it can be the gas flow during the intake and / or exhaust process of a compensation container, such as the gas flow during the intake process (e.g., ambient air flowing into the compensation container) and / or the gas flow during the exhaust process (e.g., air being discharged from the compensation container, e.g., flowing out).

[0023] Impurities, particularly liquid and / or solid particles, can refer to undesirable materials, particles, compounds, and / or substances present in a medium (e.g., a gas stream) that may impair its purity, quality, and / or function. Liquid impurities may include, for example, water, oil, solvents, acids, alkalis, or other chemicals that have accidentally entered the gas stream. Solid particulate impurities may include, for example, dirt, dust, soot, metal shavings, glass particles, or other solid matter that has accidentally entered the gas stream. Impurities may also include, for example, moisture, such as water in ambient air, which can be separated out.

[0024] "Separation" can be understood as separating, removing, isolating, absorbing, retaining, capturing, collecting, reducing and / or decreasing impurities, especially liquid and / or solid particles, and / or other substances, compounds or materials, from a medium (e.g., a gas stream) in order to, for example, remove, clean, purify and / or clarify the gas stream.

[0025] "Adsorbent" can be a raw material, material, or substance having the ability to bind and / or adsorb gaseous, liquid, solid, and / or dissolved substances onto its surface and / or absorb them. Adsorbents can be used to separate (e.g., remove or reduce) unwanted and / or harmful substances from a medium. This can occur, for example, when the adsorbent comes into contact with a medium, such as a gas stream (e.g., air), or when the adsorbent is exposed to the medium. Therefore, an exemplary gas stream does not necessarily need to (e.g., completely) flow through the adsorbent to separate impurities, but merely contact with and / or flow onto the adsorbent is sufficient to utilize the adsorbent's capabilities / properties. Adsorbents can be adsorbents and / or absorbents. Therefore, adsorbents can separate impurities as follows: i) particularly by being completely traversed by a gas stream; ii) passively, for example, located in and / or contacted by a gas stream; and iii) in combination with i) and ii). This applies to all aspects, embodiments, and / or adsorbents described herein.

[0026] Adsorption can refer to the process by which particles, molecules, or ions in a gas or liquid combine and / or adhere to the surface of an adsorbent, for example, due to surface properties and / or surface states, such as porous structures and / or large surface areas. Adsorption can be achieved through weak attractive forces (e.g., van der Waals forces or chemical bonds) between adsorbate molecules and adsorption sites on the adsorbent surface. Adsorbates (e.g., substances that accumulate at interfaces) aggregate on the surface and form thin layers or monolayers.

[0027] Absorption can refer to the process by which particles and / or substances penetrate and / or dissolve in and / or are incorporated into another material, for example, through a chemical reaction. During absorption, the adsorbent (absorbent) incorporates the adsorbate into its own (e.g., internal) structure by penetrating or dissolving the adsorbate into the material. Unlike adsorption, the interaction between the adsorbent and the adsorbate can extend beyond the surface and occur within the adsorbent.

[0028] Adsorbents can be desiccants, used to separate, and especially remove, moisture from a gas stream, particularly from the gas stream of a compensating container during intake and / or exhaust. A desiccant is a substance or material capable of absorbing moisture from the surrounding environment and / or gas stream to create a drier environment or a drier gas stream. Desiccants can be used to remove moisture and reduce air humidity, as high air humidity (e.g., in an oil compensating container) is detrimental, for example, reducing the insulating properties of the cooling oil. As described below, an example of a desiccant is silica gel containing silica.

[0029] The device according to the invention may include a housing configured to hermetically isolate the adsorbent from its surrounding environment, and the adsorbent is only exposed to and exposed to air during device installation, particularly upon reaching the final installation position, or after device installation by pressure application, particularly pressure pulses. Therefore, the adsorbent in the device according to the invention can be hermetically isolated from its surrounding environment in such a way that it is only exposed to and exposed to air during device installation, particularly upon reaching the final installation position, or after device installation by pressure application, particularly pressure pulses.

[0030] "Airtight seal from the surrounding environment" can refer to a seal, enclosure, and / or barrier that is, (e.g., completely) airtight and / or gas-tight (e.g., airtight) and prevents gas exchange (e.g., air ingress and escaping) between the environment and the adsorbent. For example, no air, gas, and / or liquid can enter and / or come into contact with the isolated adsorbent, nor can it escape from the adsorbent.

[0031] "Exposing" an adsorbent can be understood as bringing it into contact with the environment, such as establishing a fluid connection with ambient air. Therefore, "exposure" can refer to releasing, opening, and / or making the adsorbent accessible, such as allowing an ambient medium (e.g., air) to come into contact with and / or enter the adsorbent, and the adsorbent can be contacted and / or flowed through and / or at least interact with a gas flow.

[0032] "Final installation position" can refer to the final position, arrangement, connection, and / or orientation of a component or part (e.g., the device according to the invention) after the installation process. For example, it can refer to the state in which a component is correctly installed and / or secured in its final position, such as in terms of spatial orientation, positioning relative to other components, and / or corresponding fixation / connection to or within the overall system.

[0033] A "pressure pulse" can be a change in pressure (especially a short-lived one), such as a rise and / or fall in pressure (especially a rapid one), and / or a pressure action (especially a shocking, rapid, and / or sudden one). Therefore, a pressure pulse can be a (especially rapid and / or sudden) increase and / or decrease in pressure. Pressure pulses can occur, for example, during the intake and / or exhaust of a compensating container, or they can be artificially generated. Pressure pulses can be used to transfer energy, for example, to open vents and / or expose the adsorbent to air, especially after the device has reached its final installation position (e.g., after installation). This means that by generating a pressure pulse (e.g., from a compensating container), vents can be (e.g., actively) opened and / or disrupted to expose the adsorbent to air.

[0034] Pressure pulses can be generated, for example, by targeted pressure changes and applied to vents. This can be achieved, for example, by rapidly releasing pressure and / or abruptly removing blockages, such as during container intake and / or exhaust. A pressure pulse can open the vent, exposing previously blocked adsorbent to ambient air, allowing it to come into contact with the air and perform its drying function. In this example, the vent can be designed as a diaphragm. The advantage of using pressure pulses to open vents is that the process can be automated and efficient, for example, during container intake and / or exhaust.

[0035] The device according to the invention may include a housing. The housing may be configured to contain an adsorbent. The adsorbent may be disposed inside the housing. The adsorbent may be hermetically isolated from its surrounding environment by the housing.

[0036] The shell may extend along its longitudinal axis and / or have rotational symmetry. The shell may be made of a homogeneous material and / or integrally molded, and may have, for example, a generally cylindrical and / or rectangular shape. The shell may be made of, for example, metal, a metal alloy (e.g., containing steel), or plastic. The shell may enclose and / or surround an internal space in which an absorbent may be disposed, for example, and which is then airtightly isolated.

[0037] The housing can be configured to automatically expose the adsorbent to air, particularly upon or by reaching the final installation position. This can be achieved, for example, by relative movement of the device during installation. Alternatively, the housing can also be configured to automatically expose the adsorbent to air, particularly after installation, especially by pressure, particularly by pressure pulses. This ensures, for example, that the adsorbent fully exerts its adsorption properties only after the device according to the invention reaches the final installation position (e.g., after resealing and / or, for example, when the exchange container is actually inlet and / or outlet). This prevents or reduces premature loading of the adsorbent during installation, and / or maintains the adsorbent's moisture-absorbing capacity, for example, until the device reaches its intended use position. However, this can also be ensured even after installation. The exposure of the adsorbent within the housing can be automatic, independent, self-triggered, and / or autonomous (e.g., without human intervention) and / or controllable, for example, the timing of adsorbent exposure can be controlled and / or determined by the installation of the device or by reaching the final installation position. The same applies to pressure pulses; they can be performed, for example, automatically, independently, self-triggered and / or autonomously (e.g., without human intervention) and / or under control, such as during the intake and / or exhaust of a compensating container.

[0038] The housing may have a vent for releasing the adsorbent. This vent may, for example, allow fluid connection to the environment (e.g., controlled and / or automatic connection) and allow air to flow in and out of the housing (e.g., into / out of the internal space where the adsorbent is located). The vent may initially be closed and, for example, opened upon reaching the final installation position. The vent may open and / or close automatically, independently, and / or in a controlled manner. The vent may also be opened or opened during the process of reaching the final installation position, for example, by continuously, gradually, or segmentally widening the opening, for example, during device installation. If pressure is used, especially pressure pulses, the vent may be designed as a diaphragm, which may be broken, penetrated, opened, and / or exposed by pressure.

[0039] The vent can be implemented to be opened, and especially to be damaged, particularly by mechanical force and / or pressure pulses, to expose the adsorbent to air, for example, by reaching the final installation location, or after installation, particularly by pressure action, especially pressure pulses. Therefore, the vent can be removed (e.g., torn off) and / or intentionally damaged (e.g., pierced, cut, deformed, opened, punctured, and / or cut open) to establish a fluid connection, particularly with the interior of the housing, for example, to allow gas flow to reach and / or contact or flow through the adsorbent, or both. The vent can be designed to be thinner, for example, with a smaller thickness or a wall thickness less than, for example, one or more outer walls of the housing. A predetermined break point can also be provided on the vent. Furthermore, it is conceivable that the vent is made of other materials (e.g., easily cut). For example, the vent can also be designed as a diaphragm, which can be damaged, for example, by establishing gas pressure or a gas pulse.

[0040] In the device according to the invention, in the final installed position of the device, the adsorbent may be exposed and in contact with air at at least one location. A gas flow may, for example, contact the adsorbent at this at least one location (e.g., flow onto the adsorbent) to separate impurities. In the device according to the invention, in the final installed position of the device, the adsorbent may also be exposed and in contact with air, preferably at at least two locations. In this way, for example, a gas flow may flow through the adsorbent, for example, entering the adsorbent at a first location and exiting the adsorbent at a second location, to separate impurities. However, it should be noted that the gas flow may also contact the adsorbent only at each of the two locations (e.g., flow onto the adsorbent) to separate impurities; that is, it is not mandatory to (e.g., completely) flow through the adsorbent, and a combination of gas flow contact and flow through is also feasible.

[0041] The housing may have an opening on the side opposite the vent, such as an adsorbent receiving opening, in particular, for receiving adsorbent. Adsorbent can be introduced into, removed from, and / or replaced or updated through this adsorbent receiving opening.

[0042] The device according to the invention may include an adsorbent activation element adapted to move the device to a final installation position and / or expose the adsorbent. The adsorbent activation element may be connected to the housing.

[0043] The adsorbent activation element may include a closed section adapted to: hermetically seal the adsorbent within the housing, particularly at the adsorbent receiving opening; and / or expose the adsorbent at least in sections at the adsorbent receiving opening and allow it to come into contact with air, particularly upon reaching the final installation position. The adsorbent activation element may be connected to the housing, thus enabling directional, independent, controlled, and / or automatic activation and / or use of the adsorbent, for example, only at the final installation position of the device according to the invention.

[0044] The enclosed section can be designed, for example, as a flat, dense, and / or sealed surface or structure that engages with, in particular, closely abuts (e.g., a sealed abutment) the adsorbent receiving opening and / or the adsorbent and / or the housing, and can hermetically seal the adsorbent. When the enclosed section is closed (e.g., against the adsorbent and / or the housing), an hermetically sealed barrier can be formed that shields the adsorbent (especially completely) from ambient air or ambient gas flow. This allows the adsorbent to be rapidly encapsulated in a hermetically or media-sealed manner. This prevents, for example, unwanted moisture and / or impurities from entering the housing and avoids premature activation or loading of the adsorbent.

[0045] Alternatively, the adsorbent can also be completely sealed and / or hermetically isolated by the housing itself, for example, through a connection (e.g., adhesive, welding, brazing, clamping, etc.) after the adsorbent is inserted. The housing can also be designed accordingly, for example, to have a movable opening (e.g., a cover, diaphragm, cap, interface, etc.) that can be opened and / or closed. Therefore, the use of the adsorbent activation element described herein is optional and represents only one preferred embodiment.

[0046] The adsorbent activating element may include a fixing section for securing it to a housing. The fixing section may be designed as, for example, cylindrical, such as a hollow shaft, and may accommodate (e.g., surround or enclose) the housing and thus connect thereto. One possible connection method is to use a threaded section located on the housing (especially the outer wall) and a corresponding threaded section located on the fixing section (e.g., the inner wall, such as the inner wall of a hollow shaft). However, other / alternative connection methods are also feasible, as long as a corresponding connection between the adsorbent activating element and the housing can be achieved, such as a plug-in connection.

[0047] The adsorbent activation element may extend along the longitudinal axis of the housing and / or have rotational symmetry. The adsorbent activation element may be made of a homogeneous material and / or integrally molded. The adsorbent activation element may be made, for example, of metal, metal alloy (e.g., containing steel), or plastic. The adsorbent activation element may be made, for example, of the same material as the housing.

[0048] As previously described, the adsorbent activating element can be connected to the housing. In the (e.g., fully) connected state, the device can be in a closed state. In this closed state, the device according to the invention can be transported, for example, in an airtight manner, such as before reaching the final installation location or before the final installation of the device.

[0049] In the closed state, the sealed section can abut against the adsorbent receiving opening, so that the adsorbent is (especially hermetically) sealed within the housing. In the closed state, the vent can be (e.g., completely) intact, thereby allowing for hermetically sealing or sealing of the adsorbent. For example, the size of the adsorbent can be designed to substantially match the internal space of the housing, e.g., fill the internal space of the housing. Preferably, the size of the adsorbent can be designed to be slightly larger so that, for example, when the adsorbent activation element is connected to the housing, air contained in the adsorbent can be expelled, for example, by compression, especially by completely venting it.

[0050] When the device according to the invention reaches the final installation position, the device may be in an open state, or the device according to the invention may be placed in an open state by installation or by reaching the final installation position, for example automatically, independently, autonomously and / or in a controlled manner.

[0051] In the open state, the closed section can be spaced apart from the adsorbent receiving opening, such that the adsorbent is at least partially, particularly sectionally, exposed within the housing, for example, at a first (or second) position. This can be, for example, a result of the device installation process. Furthermore, in the open state, the vent is at least partially opened (e.g., damaged), for example due to installation and / or (e.g., after installation) by a pressure pulse, thereby exposing the adsorbent at another position, for example, a second (or first) position different from the first (or second) position. In this way, for example, a gas flow can permeate the adsorbent, for example, entering the adsorbent at the first (or second) position and exiting from the adsorbent at the second (or first) position, or vice versa. However, it is sufficient for the adsorbent to be in contact with air at both positions (e.g., a gas flow onto the adsorbent), i.e., the adsorbent does not need to be forcibly (e.g., completely) permeated by the gas flow. A combination of gas flow contact and permeation is also feasible.

[0052] Adsorbents may contain one or more of the following substances: silica, especially silica gel; calcium chloride; sodium carbonate; potassium carbonate; sodium sulfate; magnesium sulfate; calcium sulfate; montmorillonite; bentonite; calcium silicate; silicon nitride; zirconium oxide; titanium oxide; activated carbon; zeolite; alumina and / or molecular sieves (especially molecular sieves with a pore size range of approximately 3 Å to 10 Å).

[0053] The aforementioned adsorbents (especially silica gel) may, for example, be provided with a protective layer (e.g., a protective film) before their intended use to facilitate transport and prevent contamination or premature moisture absorption, such as through media sealing and / or airtightness. In this way, a desiccant can be introduced into the device (e.g., housing), and the protective layer can be removed only just before sealing, for example by activating the element with the adsorbent. This, for example, can prevent or minimize premature loading and maintain the moisture-absorbing capacity of the adsorbent.

[0054] The device according to the invention, for example in an assembled state (e.g., when the adsorbent activating element is connected to the housing), can be configured to be substantially cylindrical and / or rectangular, especially to be cylindrical. This shape can be determined by the shape of the housing, which can also be designed to be substantially cylindrical and / or rectangular. The cylindrical body can be referred to as a container or core and is adapted to contain and / or hermetically seal a particular material (e.g., an adsorbent).

[0055] The cylinder according to the invention can be a self-opening cylinder, wherein, particularly upon reaching or by reaching the final installation position, or after installation by pressure, particularly a pressure pulse, the vent is independently, autonomously, controlled, and / or automatically opened to expose the adsorbent to air, for example, at a first (or second) position. Furthermore, upon reaching the final installation position, the cylinder can also expose the adsorbent to air at at least one other position, such as a second (or first) position, particularly independently, autonomously, controlled, and / or automatically, for example, by an adsorbent activation element.

[0056] The device according to the invention can be connected to, in particular attached to, or installed in a gas exchange container. The gas exchange container may include a housing having a receiving opening for introducing (in particular for mounting and / or securing) the device and a compensation container interface for connecting the gas exchange container to a compensation container to be exhausted (in particular, an oil compensation container for motor vehicles). The housing may be made of a homogeneous material and / or integrally molded. The housing may be made, for example, of metal, metal alloys (e.g., containing steel), or plastic. The housing may be made of the same material as the shell and / or the adsorbent activation element.

[0057] In particular, the final installation position can be reached when the device is (e.g., fully) introduced into and / or connected to the gas exchange container, especially the receiving opening. To determine the final installation position, stops, especially protrusions, can be used, for example, to provide a rotational locking function. For example, the stops or protrusions can be located on the housing, and when the device according to the invention is introduced into the gas exchange container, these stops or protrusions can interact with, especially engage with, stops or protrusions inside the gas exchange container, for example, to determine, in particular, the maximum insertion length and, for example, the final installation position.

[0058] When the device according to the invention is fixed inside a gas exchange container, especially when it is fully introduced (e.g., until the protrusions abut against each other), particularly in the final installation position, the device can be sealed, especially airtight, inside the gas exchange container relative to the surrounding environment.

[0059] In other words, when the device according to the invention is introduced into a gas exchange container, a new, especially airtight, unit can be formed, such as the system according to the invention. The system according to the invention can be used, for example, for transport, to prevent the adsorbent in the gas exchange container from being prematurely loaded, for example, before the gas exchange container is connected to, and especially attached to, the oil compensation container.

[0060] The gas exchange container also includes an exposure element. This exposure element can be made of a homogeneous material and / or integrally molded, particularly formed from the gas exchange container or its housing, for example, from the same material; or it can be made separately. The exposure element can be a pin, particularly a mechanical pin.

[0061] Alternatively, the exposure element can also be a cutting tool (e.g., a blade) and / or (e.g., a pressure-applying) break pin, to expose, for example, a vent. The exposure element can be adapted to open, expose, open, especially break, penetrate, and / or cut off the vent of the housing, particularly by reaching the final installation position, to expose the adsorbent at a first (or second) location and expose it to air. The vent can be opened, particularly inside a (e.g., sealed) gas exchange container, to prevent premature loading of the adsorbent, e.g., before intended use. Alternatively, pressure action, particularly a pressure pulse, can also be used for exposure, in which case the exposure element can be optional.

[0062] Adsorbent activation elements can be adapted to expose the adsorbent (especially during installation) at a second (or first) location, at least in sections, to contact with air.

[0063] The flow path of the gas stream (especially from the compensating container to be vented) can be from the first position to the second position, or vice versa. Alternatively, the gas stream can flow only to these two positions, i.e., only in contact with them, to separate impurities. A combination of gas stream contact and through-flow is also feasible.

[0064] The gas exchange container may also have a fixing device for securing the device according to the invention within the gas exchange container, particularly in the area of ​​the vent. The gas exchange container may have an inlet and / or an outlet to facilitate gas exchange (e.g., with the environment). The fixing device and / or the inlet and / or outlet may be made of a homogeneous material and / or integrally formed, particularly from the gas exchange container or its shell, for example, from the same material; or they may be made separately. The same applies to the compensation container outlet. Attached Figure Description

It is proposed that elements and features of one embodiment may be advantageously incorporated into other embodiments without further explanation. Generally, only the differences between the various embodiments are described.

[0068] Each embodiment is used to illustrate this disclosure and should not be construed as limiting it. Furthermore, features shown or described as part of one embodiment may be used in combination with other embodiments to produce another embodiment. This specification is intended to cover such modifications and variations.

[0069] Figure 1A An exploded view of an apparatus 100 according to the invention is shown, which is used to separate impurities, particularly liquid and / or solid particles, from a gas stream, especially from a compensation container in a motor vehicle, particularly an oil compensation container.

[0070] Figure 1A The device 100 includes a housing 110. Figure 1A In this design, the housing 110 is shown as cylindrical or tubular, but this only represents a preferred embodiment of the invention, and other shapes / configurations are also possible, such as rectangular.

[0071] Device 100 may include a housing 110 adapted to contain, for example, absorbent 120 within an internal space 112. The housing 110 may be configured to hermetically isolate the absorbent 120 from its surrounding environment, and only when device 100 is installed, particularly by reaching the device's final installation location (see, for example, see...). Figure 3B and Figure 4-5 The adsorbent is exposed to air only after the device 100 is installed, especially by pressure pulses and / or pressure action.

[0072] The housing 110 may include a vent 114 adapted to: expose the adsorbent 120 within the housing 110 to establish a fluid connection, for example, with the adsorbent; and / or expose the adsorbent 120 to air (e.g., ambient air 150 and / or a gas flow from the compensation container). For example, the vent 114 may be designed to be thinner than, for example, one or more outer walls of the housing 110, i.e., less thick and / or thinner. A predetermined break point may also be provided on the vent 114, or other materials, such as those more easily damaged or more easily penetrated, may be used. When pressure is applied, especially a pressure pulse, the vent 114 may be designed as a diaphragm (not shown).

[0073] The housing 110 may also have an opening 116, such as an adsorbent receiving opening 116. The adsorbent receiving opening 116 may be arranged on the side opposite to the vent 114 and adapted to receive adsorbent 120. Thus, adsorbent 120 may be introduced into the housing 110 through the adsorbent receiving opening 116, for example, and disposed therein, for example, in the internal space 112. Through the adsorbent receiving opening 116, adsorbent 120 may be introduced into, removed from, and / or replaced or updated, for example, in the housing 110.

[0074] Device 100 may further include an adsorbent activation element 130, which may be configured to move device 100 to a final installation position and / or expose adsorbent 120. Adsorbent activation element 130 may include a closure section 132. The closure section 132 may be adapted to enclose adsorbent 120 (e.g., hermetically) within housing 110, particularly at adsorbent receiving opening 116, for example by abutting the closure section 132 against the housing 110 and / or the adsorbent (see, for example, see...). Figure 1B Implement the aforementioned closure. For example... Figure 1A As shown, the enclosed section 132 may be designed, for example, as a flat, dense and / or sealed surface or structure that can engage, in particular abut (e.g., seal abut) with the absorbent receiving opening 116 and / or the absorbent 120 and / or the housing 110, and can hermetically seal the absorbent 120.

[0075] Alternatively, the absorbent 120 may also be completely sealed and / or hermetically isolated by the housing 110 itself, for example, through a connection (e.g., adhesive, welding, brazing, clamping, etc.) after the absorbent 120 is introduced, via material fit, shape fit, and / or force fit. The housing 110 may also be designed accordingly, for example, to have a movable opening (e.g., a cover, cap, interface, etc.) that can be opened and / or closed to insert and / or replace the absorbent 120. Therefore, the absorbent 120 described herein... Figure 1A The use of the adsorbent activating element 130 shown is optional and represents only one preferred embodiment.

[0076] The adsorbent activation element 130 may include a retaining section 134 for attachment to the housing 110. The retaining section 134 may be cylindrical, as shown in FIG1, for example, it may be designed as a hollow shaft and may, for example, accommodate (e.g., surround) and be connected to the housing 110.

[0077] The adsorbent activation element 130 can be secured to the housing 110, for example, via a fixing section 134. For example, the housing 110 may include a fastening device 118 for securing the adsorbent activation element 130. Figure 1AIn this design, the fastening device 118 is a threaded section 118, particularly an external thread, located, for example, on the outside of the housing 110. Other fastening methods, such as plug-in connections, are also conceivable. The absorbent activating element 130 may include corresponding (e.g., mating) fastening devices 136. Figure 1A In this context, the fastening device is indicated by a corresponding or mating internal thread 136. The fastening devices 118 and 136 can secure the adsorbent activation element 130 to the housing 110, and / or encapsulate the adsorbent 120 within the housing 110, for example, by screwing and / or tightening. The adsorbent activation element 130 is (removably) connected to or mounted on the housing 110. Figure 1A The middle is indicated by arrow 140, while Figure 2 This shows the state in which the adsorbent activating element 130 is, for example, fully connected or fixed to the housing 110.

[0078] The adsorbent activation element 130 may also include an engagement section 138 adapted to enable connection 140 with the housing 110 and / or to move the device 100 to its final installation position (see, for example, see...). Figure 3B As shown in Figure 1, the engagement section 138 may be designed as a hexagon, for example, to mount the device 100, for example, by mounting, inserting and / or screwing the device 100 into, for example, a gas exchange container 200 via a corresponding threaded section 137 (see Figure 1). Figure 2 ).

[0079] The housing 110 may also include (in particular) an elongated protrusion 119, which may serve, for example, as a stop or rotation lock during installation of the device 100, for example, into the gas exchange container 200 (see [link]). Figure 2 (especially when used in conjunction with the corresponding rotary locking device 209) to, for example, limit the maximum insertion length of the device and / or the final installation position. This will be described in more detail below with reference to the accompanying drawings.

[0080] Figure 1B An apparatus 100 according to the invention is shown for separating impurities, particularly liquid and / or solid particles, from a gas stream, especially the gas stream of a compensation container in a motor vehicle, particularly an oil compensation container. Figure 1A The components shown are interconnected, especially assembled or installed together. Figure 1B In the middle, device 100 is in a closed state. From Figure 1B It can also be seen that the adsorbent activation element 130 has been connected to the housing 110, for example, fully tightened, but the device has not yet reached its final installation position. Therefore, Figure 1BThe device 100 (e.g., as a cylinder 110) is shown before and / or upon reaching its final installation position (e.g., in a gas exchange container 200, see...) Figure 2 (The previous state.) Figure 1B The device shown is suitable for transportation, for example, and can prevent the adsorbent 120 from being loaded prematurely.

[0081] exist Figure 1B In the closed state shown, the closed section 132 abuts against the absorbent receiving opening 116 (see...). Figure 1A ) and / or housing 110 and / or adsorbent 120, such that adsorbent 120 is (especially hermetically sealed) within housing 110. According to Figure 1B The vent 114 is (e.g., completely) intact in the closed state, so that the absorbent 120 can be hermetically sealed, for example, until the final installation position is reached, to prevent, in particular temporarily, fluid connection (e.g., flow of gas into, into, through and / or out).

[0082] The device 100 may also have one or more sealing elements, such as a primary sealing element 152 and an auxiliary sealing element 154, particularly for use during the installation of the device 100 (e.g., installation within a gas exchange container 200, see below). Figure 2 The main sealing element 152 can further ensure the seal of the adsorbent 120 within the housing 110, for example, by preventing ambient air 150 from contacting the adsorbent 120 via fastening devices 118 / 136. The main sealing element 152 can be installed in the gas exchange container 200 (see...). Figure 2 or Figure 3B The gas is exposed or opened within the gas exchange container 200 to, for example, achieve a fluid connection, such as ensuring that the gas flow only comes into contact with and / or passes through the adsorbent 120 within the gas exchange container 200 (see [link]). Figure 4-5 The auxiliary sealing element 154 can be adapted, for example, to seal the internal space of the gas exchange container relative to the external environment, particularly during the insertion or installation of the device into the gas exchange container 200. This will be described in more detail below with reference to the accompanying drawings.

[0083] Figure 2 A gas exchange container 200 is shown, which can be attached to a compensation container, particularly an oil compensation container (not shown). The gas exchange container 200 may have a housing 202. The housing 202 may have a receiving opening 204, for example for receiving, introducing, and / or securing the device 100, for example via a fastening device 137 (see [link]). Figure 1A and 1B The housing 200 may have a compensation container interface 206 for connection to a compensation container to be vented, particularly an oil compensation container. Figure 2As shown, the compensation container interface 206 can be sealed, for example, with a plug 208 before assembly with an oil compensation container (e.g., a vehicle's), which prevents gas exchange, such as gas inflow and / or outflow. The plug 208 can be a sealing plug 208 that can be removed just before being connected to the oil compensation container.

[0084] The gas exchange container 200 may also have an engagement section 209, such as a protrusion or stop, which mates with the (especially elongated) protrusion 119 of the device 100, for example, acting as a rotational lock when the device 100 is introduced into the gas exchange container 200. Thus, the final installation position and / or maximum insertion length of the device 100 can be defined, for example, by the corresponding alignment, sizing, and / or positioning of the protrusions 109 / 209. The protrusion 209 may be formed, for example, by the housing 202, or it may be formed separately.

[0085] The gas exchange container 200 may also include an exposure element 210. Figure 2 In this context, the exposure element 210 is formed from the outer shell 202 of the gas exchange container 200. The exposure element 210 is located within... Figure 2 The device is designed as a pin; alternatively, cutting tools (e.g., blades) and / or (e.g., pressure-applied) break pins may be used. The exposure element 210 may be adapted, at least via a vent 114 for opening, exposing, opening, especially breaking, penetrating, and / or cutting the housing 110 upon reaching the final installation position, so as to expose the adsorbent 120 to air at a first (or second) position. Alternatively, the exposure element 210 may be optional, for example, when pressure action (especially pressure pulses) is used after device installation to expose the adsorbent and expose it to air. In this case, the vent 114 may be designed as a diaphragm.

[0086] like Figure 2 As shown, a vent 114 can be opened, particularly at a location inside (e.g., within a sealed) gas exchange container 200 (e.g., within the housing 202), to prevent premature loading of the adsorbent 120 (e.g., before intended use). A pin 210 allows the adsorbent 120 to be exposed to air at a first (or second) location. Reference will be made below. Figure 3B This will be described in more detail. As mentioned earlier, diaphragms, pressure pulses, and / or pressure applications can also be used alternatively.

[0087] The gas exchange container 200 may also have a fixing device 212 for securing the device 100 within the gas exchange container 200, particularly in the area of ​​the vent 114. Figure 2As shown, the fixture 212 can be made of a homogeneous material and / or integrally molded, for example, integrally molded with the housing 202 of the gas exchange container 200. The fixture 212 can be made of, for example, metal, metal alloy (e.g., containing steel), or plastic. The gas exchange container 200 may also have an inlet port 214 and / or an exhaust port 216 to facilitate gas exchange. The inlet port 214 and / or exhaust port 216 may also be sealed relative to the environment 150, for example, using plugs, such as sealing plugs (e.g., similar to sealing plug 208). The inlet port 214 and / or exhaust port 216 may also be connected to or attached to other pipes and / or channels.

[0088] Figure 3A A system 300 according to the invention is shown, which is used to separate impurities, particularly liquid and / or solid particles, from a gas stream, especially a gas stream from a compensation container in a motor vehicle, particularly an oil compensation container. The system 300 according to the invention includes a device 100 according to the invention (see [link to device 100]). Figure 1A and / or 1B) and a gas exchange container 200 for connection to a compensation container, particularly an oil compensation container (not shown) (see Figure 2 ).

[0089] Figure 3A The diagram shows the state of the system 300 according to the invention during the installation process of the device 100 according to the invention, i.e., the state before the device 100 according to the invention reaches its final installation position, for example, before the device 100 is fully installed in the gas exchange container 200.

[0090] like Figure 3A As shown, device 100 is in a closed state (see Figure 100). Figure 1B At this point, the enclosed section 132 abuts against the absorbent receiving opening 116 and / or the housing 110 and / or the absorbent 120 (see...). Figure 1A This allows the adsorbent 120 to be (especially hermetically sealed) within the housing 110. For example... Figure 3A As shown, the vent 114 is closed or intact in a closed state and / or before reaching the final installation position, so gas exchange or fluid connection between the adsorbent 120 and the environment 150 is not yet possible.

[0091] During the introduction of device 100 into gas exchange container 200, primary sealing element 152 can provide an additional seal relative to environment 150, for example ensuring that no air intrudes from environment 150 during installation (e.g., into housing 202). At this time, auxiliary sealing element 154 may still be exposed, such as... Figure 3A As shown.

[0092] Figure 3B It shows Figure 3AThe system 300 according to the invention, wherein the device 100 according to the invention is in Figure 3B The device has reached its final installation position, for example, the device 100 has been fully introduced (e.g., installed) into the gas exchange container 200, especially into the receiving opening 204.

[0093] like Figure 3B As shown, device 100 is in the open state.

[0094] like Figure 3B As shown, in the open state, the closed section 132 can be spaced apart from the absorbent receiving opening 116, such that the absorbent 120 is at least partially, particularly sectionally, exposed within the housing 110, for example at the second (or first) position 320. This can be, for example, a result of the device installation process, such as when the device 100 is introduced. For example, when fastening devices 118, 136, and 137 (see...) Figure 1A ), 217 (see Figure 2 This can be achieved when the corresponding mating threads are designed so that, for example, when the device is introduced, the closed section 132 is away from the housing 110 and / or the absorbent receiving opening 116 and / or the absorbent 120.

[0095] like Figure 3B As shown, in the open state, the vent 114 is at least partially opened (e.g., damaged), for example due to or by installation and / or by reaching the final installation position, or for example after installation due to pressure, particularly a pressure pulse (not shown). For example, during or by installation, the pin 210 pierces the vent 114, thereby exposing the absorbent 120 at another, for example, first (or second) location 310. In this way, for example, gas flow (see...) Figure 4 The absorbent 120 can be permeated, for example, entering the absorbent 120 at a first position 310 (or a second position 320) and exiting the absorbent 120 at a second position 320 (or a first position 310), or vice versa. However, it is sufficient for the absorbent 120 to be in contact with air at both positions 310, 320 (e.g., a gas flow onto the absorbent 120), meaning the absorbent 120 does not need to be forcibly permeated (e.g., completely) by the gas flow. A combination of gas flow contact and permeation is also feasible.

[0096] like Figure 3B As shown, for example by fastening devices 118 and 136 (see...) Figure 1A In the final installation position of the implementation device 100 and / or in the open state, the primary sealing element 152 is exposed, thereby enabling fluid connection. The auxiliary sealing element 150 can provide additional sealing relative to the environment 150, for example ensuring no gas exchange occurs through the fastening device 137 (see [link to documentation]). Figure 1A) and 217 (see Figure 2 )occur.

[0097] It is important to note that, Figure 3B In this system, the gas exchange container 200 (i.e., the system according to the invention), in which the device 100 is arranged, is closed, especially sealed relative to the environment 150, particularly airtight. Figure 3B As shown, for example, the compensation container interface 206 is sealed by a plug 208. The inlet interface 214 and / or the exhaust interface 216 are also similarly sealed by plugs (not shown). Therefore, the device 100 is sealed, particularly hermetically sealed, relative to the environment 150 within the gas exchange container 200. In other words, when the device 100 according to the invention is introduced into the gas exchange container 200, i.e., when it reaches... Figure 3B When the final installation position is shown, a new sealed unit 300 is formed, for example, according to the system of the invention, which is isolated from the environment 150, especially hermetically isolated. This can be used, for example, for transport, to prevent the adsorbent 120 from being prematurely loaded into the gas exchange container 200, for example, before the gas exchange container 200 is connected to the oil compensation container (not shown), especially before, for example, before being attached via the compensation container interface 206.

[0098] It should be noted that references to the first (or second) position and / or the second (or first) position in this article can be used interchangeably.

[0099] Figure 4 The diagram illustrates a possible flow path for a gas flow GS (e.g., from inside the oil compensation container) when the gas exchange container 200 is connected to the oil compensation container, for example, via the compensation container interface 206, and a fluid connection is established, particularly for venting the oil compensation container. (See gas flows 410-440). Thus, the gas flow GS can enter the gas exchange container 200 and / or the device 100, for example, via the compensation container interface 206, and contact the adsorbent 120 to separate impurities during venting.

[0100] Figure 4 Only one direction of the gas flow GS is shown, for example, during the exhaust process of the compensation container. Obviously, the gas flow GS can also flow in the opposite direction, for example, during the intake process of the compensation container (see...). Figure 5 Furthermore, this can obviously be achieved through the intake port 214 and / or exhaust port 216 shown, respectively.

[0101] like Figure 4 As shown, plug 208 has been removed, allowing gas flow GS (particularly for intake and / or exhaust of the oil compensation container) to enter gas exchange container 200 through compensation container interface 206 (see gas flow 410). Gas flow 410, for example, at first position 310 (see... Figure 3B Through the vent 114, which has been broken, for example, by pin 210 when reaching the final installation position or by pressure pulse and / or pressure action after installation, the gas flow GS can contact the adsorbent 120 and can separate impurities, for example, by the gas flow onto it.

[0102] Alternatively or additionally, the gas flow GS may penetrate and pass through the adsorbent 120 (see gas flow 420), for example, until the gas flow reaches the closure element 132. Since the device 100 is in the open state, the closure section 132 is spaced apart from the adsorbent receiving opening 116 and / or the housing 110 and / or the adsorbent 120, such that the adsorbent 120 in the housing 110 is at least partially, especially sectionally, exposed, for example at the second location 320 (see...). Figure 3B ).

[0103] In this way, for example, a gas flow GS can, for instance, flow through the adsorbent 120, entering or penetrating it at a first location 310 and exiting it at a second location 320, or vice versa. During the flow of the gas flow through the adsorbent 120, impurities can be separated. However, it is sufficient for the adsorbent 120 to come into contact with the gas flow GS at both locations 310 / 320 (e.g., the gas flow onto the adsorbent 120) to separate impurities; that is, the adsorbent 120 does not need to be forcibly (e.g., completely) flowed through by the gas flow. A combination of gas flow contact and flow-through is also feasible.

[0104] like Figure 4 As shown, in the final installation position and / or in the open state of device 110, the main sealing element 152 is exposed, thereby enabling fluid connection, for example by means of fastening devices 118 and 136 (see...). Figure 1A Therefore, the gas flow GS can pass through fastening devices 118 and 136 (see...). Figure 1A The airflow is directed to the intake port 214 and / or the exhaust port 216 (see Gas Flow 430). The auxiliary sealing element 154 can provide an additional seal relative to the environment 150, for example, for fastening device 137 (see...). Figure 1A ) and 217 (see Figure 2 This ensures that the gas flow GS can only leave the gas exchange container 200 through the inlet port 214 and / or the exhaust port 216.

[0105] Subsequently, the gas flow GS can exit the gas exchange container 200 through the inlet port 214 and / or the outlet port 216 to, for example, discharge the gas in the compensation container and / or balance or compensate for changes in pressure or volume.

[0106] Figure 5The diagram illustrates a possible flow path for the gas flow GS (e.g., ambient air 150) when the gas exchange container 200 is connected to the oil compensation container, for example, via the compensation container interface 206, and a fluid connection is established, particularly for the intake of the oil compensation container (see gas flows 510-540). Thus, the ambient air 150 can enter the gas exchange container 200 and / or the device 100 and contact the adsorbent 120 to separate impurities upon intake.

[0107] Figure 5 Only one direction of the gas flow GS is shown, for example, during the intake process of the compensation container. Obviously, the gas flow GS can also flow in the opposite direction, for example, during the exhaust process of the compensation container (see...). Figure 4 Furthermore, this can obviously be achieved through the intake port 214 and / or exhaust port 216 shown, respectively.

[0108] like Figure 5 As shown, plug 208 has been removed. Ambient air 150 can enter the gas exchange container 200, for example, through air inlet 214 (see gas flow 510).

[0109] like Figure 5 As shown, in the final installed position and / or in the open state of device 110, the main sealing element 152 is exposed, thereby enabling fluid connection, for example by means of fastening devices 118 and 136 (see...). Figure 1A Therefore, the gas flow GS can pass through fastening devices 118 and 136 (see...). Figure 1A The gas flows toward the adsorbent 120 (see gas flow 520) and, for example, comes into contact with it.

[0110] The auxiliary sealing element 154 can provide an additional seal relative to the environment 150, for example, for fastening device 137 (see...). Figure 1A ) and 217 (see Figure 2 This allows the gas flow GS to continue flowing, for example, toward the compensation container, such as the through-flow adsorbent 120. Since the device 100 is in the open state, the closed section 132 is spaced apart from the adsorbent receiving opening 116 and / or the housing 110 and / or the adsorbent 120, such that the adsorbent 120 in the housing 110 is at least partially, especially sectionally, exposed, for example at the second position 320 (see...). Figure 3B ).

[0111] Subsequently, the gas flow GS can flow through the adsorbent 120 (see gas flow 530), for example, entering the adsorbent 120 at a second position 320 and exiting the adsorbent 120 at a first position 310, or vice versa. During the flow of the gas flow through the adsorbent 120, impurities can be separated, such as moisture from the ambient air 150. However, contact between the adsorbent 120 and the gas flow GS at both positions 310 / 320 (e.g., the gas flow onto the adsorbent 120) is sufficient to separate impurities; that is, the adsorbent 120 does not need to be forcibly (e.g., completely) flowed through by the gas flow. A combination of gas flow contact and flow-through is also feasible.

[0112] Gas flow, for example, at the first position 310 (see Figure 3B The gas flow GS is allowed to continue flowing to the compensation container (see gas flow 540) via a vent 114, which has been destroyed, for example, by pin 210 when reaching the final installation position or by pressure pulse and / or pressure action after installation, so that the gas flow GS can continue to flow to the compensation container (see gas flow 540) for example, to allow air to enter the compensation container and / or to balance or compensate for changes in pressure or volume.
