Description

Technical Field

[0001] The present invention relates to an air dryer device for an air treatment apparatus for a vehicle, particularly a multi-purpose vehicle, having at least one housing forming at least one receiving chamber for accommodating at least one desiccant container.

[0002] Furthermore, the present invention also relates to an air treatment device for a vehicle, particularly a multi-purpose vehicle, having at least one of the aforementioned air dryer devices. Background Technology

[0003] In the automotive field, particularly in multi-purpose or commercial vehicles, pneumatic systems are commonly used for braking, suspension, and other auxiliary systems. In these systems, air distribution is handled by multi-circuit protection valves, which can divide the air supplied by a compressor or similar device and handle the different opening and closing pressures, pressure limits, and circuit protection for each circuit.

[0004] Before controlling the pressurized air in this way, an important step is to dry the air supplied by the compressor (because it still contains atmospheric humidity). This drying process is achieved by placing an air dryer cylinder between the compressor and the multi-loop protection valve, thus supplying dry and degreased air to the multi-loop protection valve.

[0005] Such a conventional air dryer cylinder is known in the prior art.

[0006] DE3208561A1 discloses an air drying apparatus having a connecting housing on which a cap-shaped container is mounted to accommodate a dryer cylinder. For ease of changing the dryer cylinder, a clamping bracket is used, which is rotatably mounted on the housing and can rotate and be fixed in place on the container.

[0007] DE69210614T2 discloses an air dryer control system in which compressed air output from a compressor is dried by one of two air dryers connected in parallel. The cleaning and drying cycles of the air dryer are alternated by a timing and relay device.

[0008] EP0933117A1 discloses a reversing valve for a gas drying system that cleans and dries unpurified pressurized airflow received from its source and supplies the airflow to a pneumatic system using this purified pressurized air. The valve includes a housing that connects a drying assembly to a structure that delivers unpurified pressurized air to the drying assembly.

[0009] EP2448801A1 discloses an air dryer cartridge for a compressed air treatment system for vehicles, particularly commercial vehicles, comprising a spring cover and a carrier element that together define the volume of the air dryer cartridge in an assembled state, wherein a dryer cartridge is provided disposed within the volume and filled with a desiccant.

[0010] US5,901,464A relates to a dual-tower air drying system for cleaning and drying unpurified pressurized airflow, comprising: a centrifugal separator having horizontally arranged baffles to substantially divide a centrifugal chamber into an upper chamber and a lower chamber; a pair of chambers, each containing a desiccant medium and a cleaning tube, wherein a baffle valve is disposed above the cleaning tube, the baffle valve closing and restricting airflow through the cleaning tube when air flows upward through the chamber, and opening and facilitating airflow through the cleaning tube when air flows downward through the chamber.

[0011] US5,961,698A discloses a dual-tower gas drying system for cleaning and drying an unpurified pressurized gas stream received from its source for use in a pneumatic system. The drying system includes a manifold block with multiple ports. A separator and a tank are connected to such a block and one of its ports for initial separation of moisture and particulates from the unpurified gas stream and for directing the remainder of the gas stream to another port within the block.

[0012] Essentially, the desiccant in all air dryer units needs to be pre-tightened because, throughout the desiccant's lifespan, vibrations from the power system and vehicle operation cause wear and friction on the desiccant, which is formed by the contact of multiple desiccant beads or balls. This vibration leads to friction, wear, and pulverization of the desiccant beads, resulting in an overall volume loss of the desiccant (over a sufficiently long period), which must be compensated for by tension or pressure to create stable desiccant conditions.

[0013] Furthermore, the desiccant needs to be regenerated periodically because its water absorption capacity is limited, and it must be separated from the desiccant once it becomes saturated with water. During the regeneration phase, regenerated air flows through the air dryer in the opposite direction to the loading phase. Due to the typical setup of such air dryer units, control valves are usually used to properly control the regeneration process. However, according to existing technology, such control valves require very large sealing surfaces, resulting in a greater need for sealing materials, construction space, cost, and manufacturing effort, as well as a large number of parts. Summary of the Invention

[0014] Therefore, one object of the present invention is to improve the above-described air dryer device, in particular to enable more precise control of its regeneration phase and to optimize its operation and sealing performance.

[0015] According to the invention, this objective is achieved by an air dryer device with features according to the invention. Accordingly, an air dryer device for an air treatment apparatus for a vehicle, particularly a multi-purpose vehicle, has at least one housing forming at least one receiving chamber for accommodating at least one desiccant container; wherein the housing includes at least one housing inlet arranged in the bottom region of the housing in the installed state, and the housing includes at least one first connecting device and at least one second connecting device, the first and second connecting devices being connectable via the desiccant container during at least one loading phase and / or at least one regeneration phase of the air dryer device; wherein the housing includes at least one regeneration conduit device for connecting the first connecting device to the second connecting device during the regeneration phase; and wherein the housing includes at least one first control valve arranged and configured to disconnect or close the regeneration conduit device, in particular, the first control valve is arranged at the housing inlet.

[0016] The basic idea of ​​this invention is to provide at least one control valve, particularly at a housing inlet located in the bottom region of the housing, wherein the control valve is arranged and configured to disconnect or close the regeneration conduit assembly. Because the control valve is located specifically at the housing inlet, the required sealing contact area can be significantly reduced, thereby reducing the risk of leakage and the amount of sealing material required for the control valve and the air dryer housing. Furthermore, the assembly of the control valve can be automated, reducing assembly time. Additionally, the back pressure of the air dryer unit during the regeneration phase can be set more sensitively, increasing the service life of the air dryer unit's components. The location of the control valve at the bottom of the housing also simplifies maintenance and installation, as this area is readily accessible in the pre-installed state of the air dryer unit. In this respect, the first control valve generally ensures the rapid, safe, and reliable removal of contaminants, such as dust particles, oil, and / or water, from the air dryer unit during the regeneration phase.

[0017] It is conceivable that the first control valve is formed by at least one first check valve. Check valves are a well-established valve type with a long service life, ensuring safe operation throughout the service life of the air dryer unit. These valves are constructed with few parts and minimal structural space, thus providing control valves with high power density, enabling excellent control of the back pressure of the air dryer unit during the regeneration phase.

[0018] Furthermore, the housing includes at least one second check valve, which is arranged and configured to disconnect or close the regeneration conduit assembly; specifically, the second check valve is located at the housing inlet. By providing two check valves, the back pressure of the air dryer unit during the regeneration phase can be set more precisely. This precise control of the regeneration phase increases the service life of the air dryer components. On the other hand, the two check valves increase the operational safety of the air dryer unit, as the desiccant must be regenerated after a certain service life, which is impossible with only one check valve and its failure.

[0019] Additionally, the housing includes at least one third check valve, which is arranged and configured to disconnect or close the regeneration conduit assembly; specifically, the third check valve is located at the housing inlet. By providing three check valves, the back pressure of the air dryer unit during the regeneration phase can be set more precisely. Compared to solutions with one or two check valves, this highly precise control of the regeneration phase increases the service life of the air dryer components. Furthermore, the three check valves increase the operational safety of the air dryer unit, as the desiccant needs to be regenerated due to saturation after a certain service life, which is impossible or more difficult to achieve with one or even two check valves, and if both fail. Moreover, the number of three check valves can cover different built-in angles of the air dryer unit relative to the housing of paired components, such as multi-loop protection devices, or general air handling units. It is also conceivable that the housing includes at least one fourth, fifth, or sixth check valve, arranged and configured to disconnect or close the regeneration conduit assembly; specifically, these check valves are located at the housing inlet. In this regard, three or more check valves ensure the rapid, safe, and reliable removal of contaminants, such as dust particles, oil, and / or water, from the air dryer unit during regeneration. With fewer than three check valves (e.g., one or two), excess oil accumulating at the housing inlet can be guided by one or more inclined or sloping housing sections to properly direct excess oil to one or two check valves during regeneration, allowing for more efficient removal of the oil from the air dryer cylinder. Therefore, with three or more check valves, these one or more inclined or sloping housing sections are no longer necessary, thus simplifying the structure of the air dryer cylinder.

[0020] Furthermore, the first and / or second and / or third check valves are arranged at the housing inlet. As mentioned above, since the inlet of the air dryer unit is very easily accessible in the pre-installed state of the air dryer unit, this arrangement of the check valves at the housing inlet simplifies maintenance. Additionally, manufacturing work and costs can be reduced accordingly. These reduced manufacturing efforts can also be redirected to the automated manufacturing process of these check valves, as control work can be reduced because the area where the check valves to be manufactured is easily accessible. By arranging these check valves at the inlet of the air dryer unit, back pressure control can be established more precisely.

[0021] Furthermore, the first, second, and third check valves are arranged radially symmetrically or radially asymmetrically with respect to the longitudinal axis of the air dryer assembly. This arrangement simplifies manufacturing and reduces costs because standardized work and manufacturing procedures can be implemented due to the symmetrical arrangement. These reduced manufacturing efforts can also be transferred to the automated manufacturing of these check valves, as the symmetrical arrangement can be easily implemented in the control unit of these automated manufacturing equipment, thus reducing control work. In addition, the symmetrical arrangement reduces the mechanical tension on the housing, as check valves can cause some concentration of mechanical tension, which is reduced by the symmetrical arrangement. Furthermore, different possible construction angles can also be arranged symmetrically, thereby simplifying assembly. In the case of a radially asymmetrical arrangement, more advantageous freedom is available in the design of the housing inlet and / or the air dryer cylinder.

[0022] On the other hand, the first check valve is formed by at least one valve housing portion of the housing and at least one valve body of the first check valve. The advantage of this arrangement is that very few parts are required. The valve housing portion is formed directly at the bottom of the housing, so that it contains only one component. The same applies to the valve body, as it also consists of only one component, thus the entire check valve consists of only two components. Therefore, this design makes the arrangement of the check valves very simple, and the risk or probability of these valves malfunctioning is very low. In this respect, it is advantageous that the valve housing portion is integrally formed with the housing of the air dryer cylinder.

[0023] Furthermore, the valve body includes at least one diaphragm portion having at least one radial sealing lip and / or includes at least one axial sealing portion. Advantageously, the diaphragm portion has elastic properties. Therefore, no other elastic elements (e.g., springs) are required to retract the check valve to the open or closed state (depending on the check valve's configuration). Thus, a check valve with this diaphragm solution can be constructed with very simple components. The diaphragm is configured such that only the pressure gradient between the valve inlet and outlet controls the corresponding open and closed states or positions of the check valve, without any control springs. Therefore, a very simple check valve design is fundamentally provided. Furthermore, the diaphragm includes a radial sealing lip, which establishes an increased sealing area because it means the sealing surface is in the outermost radial region of the diaphragm, resulting in better sealing performance. Moreover, due to the at least one axial sealing portion, the axial sealing function of the valve body can also be very easily established, thus forming a highly integrated check valve. It is also conceivable that the axial sealing portion can be integrated into the radial sealing lip. Alternatively, the axial sealing portion is formed as a separate part of the valve body.

[0024] In particular, the valve body includes at least one resiliently compressible and expandable retaining portion. This retaining portion simplifies the installation process because it eliminates the need for additional mounting components (such as pins, threaded parts, or bolts) to secure the valve body to the valve housing portion of the air dryer unit. The retaining portion also enables automated assembly of the valve body and valve housing portion, as the valve body only needs to be pushed into the corresponding mounting space in the valve housing portion to establish its final configuration. In other words, the valve body can be secured to the valve housing portion by its own material, forming a very simple and efficient one-way valve configuration. In this regard, the resiliently compressible and expandable retaining portion can be formed as a resilient hollow pin. Alternatively or additionally, each valve body can be secured to a support portion of another component, such as a groove, shoulder, or hole in the valve housing portion of the air dryer unit.

[0025] Furthermore, the valve body is formed as a single, resilient valve body, particularly a rubber valve body. Resilient materials like rubber are very common in valve sealing technology; therefore, providing rubber in this case is advantageous. Moreover, as mentioned above, the valve body needs to simultaneously address at least the following issues: sealing surface, self-locking, and self-opening and self-closing under pressure gradients. To meet these requirements, rubber is the most advantageous material choice because there are few comparable alternatives in solving this combined problem. Rubber is also an inexpensive material, thus advantageous in this case. Alternatively or additionally, each one-way valve body may include a resilient reinforcing element (e.g., a metal reinforcing element), on which the rubber valve body is vulcanized to ensure better retention performance.

[0026] Furthermore, the second check valve is formed in the same way as the first check valve. This simplifies the design and manufacturing process of the air dryer unit and the check valve. Therefore, the technical principles and advantages discussed above regarding the first check valve also apply to the second check valve.

[0027] Furthermore, the third check valve is formed in the same way as the first check valve. As mentioned above, this arrangement simplifies the design and manufacturing process of the air dryer device and the check valve. Therefore, the technical teachings and advantages discussed above regarding the first check valve also apply to the third check valve.

[0028] According to another aspect of the invention, the air dryer device is formed as an air dryer cylinder. Since the desiccant needs to be replaced after a certain service life, which is shorter than the service life of the air handling unit to which the air dryer device is typically connected, the air dryer cylinder is a well-known solution to this problem, and thus, the air dryer cylinder is also advantageous in this invention.

[0029] According to the present invention, an air treatment device for a vehicle, particularly a multi-purpose vehicle, is equipped with at least one air dryer device as described and discussed above. The advantages and technical teachings regarding the air dryer device as described above, along with their embodiments, can also be applied to the air treatment device and its embodiments, which is a sub-unit of the air treatment device. Attached Figure Description

[0030] Further details and advantages of the invention will now be disclosed, in conjunction with the accompanying drawings, in one embodiment of the invention.

[0031] in: Figure 1 This is a schematic bottom view of an embodiment of an air dryer device for an air treatment apparatus for a vehicle according to the present invention; and Figure 2 According to the present invention Figure 1 A schematic cross-sectional view of an embodiment of the control valve of an air dryer device. Detailed Implementation

[0032] Figure 1 A schematic bottom view of an embodiment of an air dryer device 10 according to the present invention is shown. This air dryer device 10 is used in the air handling unit of a multi-purpose vehicle. Figure 1 (Not shown in the text).

[0033] The air dryer device 10 is formed as an air dryer cylinder.

[0034] The air dryer device 10 includes a housing 12 forming a receiving chamber for accommodating at least one desiccant container 14.

[0035] The housing 12 also includes a housing socket 12a, which is located in the bottom region 12b of the housing 12 in the installed state.

[0036] The housing port 12a includes a circular housing plate 12c having a plurality of star-shaped through sections 12d that are radially symmetrically oriented relative to the longitudinal axis of the air dryer housing 12.

[0037] according to Figure 1 The housing port 12a also includes a first connecting device 16 for connecting the air dryer device 10 to a compressor (not shown).

[0038] The housing port 12a also includes a second connection device 18 for connecting the air dryer device 10 to at least one control valve device.

[0039] The control valve device can be part of an air handling unit, which also includes a multi-way protection valve device.

[0040] The control valve device can also be connected to the first connection device 16 to connect it to the compressor.

[0041] The first connecting device 16 is formed by a central circular hollow cylinder 16a, which protrudes from the housing inlet 12a in the opposite direction to the desiccant container 14.

[0042] The second connecting device 18 is formed by a corresponding housing connecting portion 18a, which is arranged radially around the first connecting device 16. The housing connecting portion connects the annular space surrounding the central circular hollow cylinder 16a to the desiccant container 14 via an annular loading connecting conduit (not shown) extending radially outward relative to the desiccant container 14.

[0043] Therefore, the first and second connecting devices 16 and 18, when installed, can be interconnected via the desiccant container 14 during the loading or regeneration phase of the air dryer device 10.

[0044] In addition, housing 12 includes regeneration conduit device 12e, which is used to connect the first connection device 16 to the second connection device 18 during the regeneration phase.

[0045] The housing 12 also includes a first control valve formed as a one-way valve 20a, which is used to disconnect or close the regeneration conduit device 12e.

[0046] according to Figure 1 The first one-way valve 20a is located at the housing port 12a.

[0047] A first one-way valve 20a is arranged in a region of the housing port 12a, and the regeneration conduit device 12e enters the housing port 12a in this region.

[0048] The regeneration conduit device 12e extends between the housing inlet 12a and the desiccant container 14 for connecting the desiccant container 14 to the second connection device 18 during the regeneration phase.

[0049] according to Figure 1 The housing 12 includes a second one-way valve 20b, which is used to disconnect or close the regeneration conduit device 12e.

[0050] Similar to the first check valve 20a, the second check valve 20b is also located at the housing port 12a.

[0051] The second one-way valve 20a is also arranged in a region of the housing port 12a, where the regeneration conduit device 12e enters the housing port 12a.

[0052] In addition, housing 12 includes a third one-way valve 20c, which is used to disconnect or close the regeneration conduit device 12e.

[0053] Similar to the first and second check valves 20a and 20b, the third check valve 20c is also located at the housing port 12a.

[0054] The third one-way valve 20a is also arranged in a region of the housing port 12a, where the regeneration conduit device 12e enters the housing port 12a.

[0055] It is also conceivable that, in accordance with the above method, more (four, five, six, seven, eight, etc.) or fewer (e.g. two or even one) check valves than the three check valves 20a, 20b, 20c can be arranged at the housing port 12a.

[0056] As can be seen from the foregoing, according to Figure 1 The regeneration conduit device 12e includes three regeneration conduit sections, each associated with a one-way valve 20a, 20b, 20c, and each section extends between the housing inlet 12a and the desiccant container 14 for connecting the desiccant container 14 to the second connection device 18 during the regeneration phase.

[0057] Each regeneration conduit segment enters the housing socket 12a in its corresponding area, and the first, second, and third check valves 20a, 20b, and 20c are respectively arranged in their respective areas.

[0058] from Figure 1 It can also be seen that the first check valve, the second check valve, and the third check valve 20a, 20b, and 20c are arranged radially symmetrically with respect to the longitudinal axis of the air dryer device 10.

[0059] Alternatively, the first check valve, the second check valve, and the third check valve 20a, 20b, 20c may be arranged radially asymmetrically relative to the longitudinal axis of the air dryer device 10.

[0060] The functions of the aforementioned air dryer device are as follows: According to the loading stage, pressurized air is supplied from the external compressor to the second connection device 18 and enters the second connection device 18, and then flows through the socket 12a.

[0061] Air then flows radially outward from the desiccant container 14 to the top of the housing 12, where pressurized air changes its flow direction so that it enters the desiccant container 14 in its top region.

[0062] In the installed state, the air dryer device 10 is fixed to the control valve unit of the air handling unit for controlling the loading and regeneration phases of the air dryer device 10.

[0063] The control unit includes at least two ports or connections corresponding to the first and second connection devices 16, 18 of the air dryer device 10.

[0064] For this purpose, a suitable seal is provided between the two connecting devices 16 and 18 to avoid a direct flow path from the first connecting device 16 to the second connecting device 18. Therefore, the pressurized air then flows through the desiccant container 14 (for drying) and into the first connecting device 16, then leaves the air dryer device 10 and flows into the control valve unit, from where the pressurized air is delivered to, for example, a multi-loop protection valve.

[0065] According to the regeneration phase, the pressurized regeneration air flows in the opposite manner to the loading phase.

[0066] Therefore, pressurized regeneration air is supplied (e.g., from the regeneration container via a control valve unit) to the first connection device 16, enters it, and flows through the desiccant container 14 (for desiccant regeneration).

[0067] Then, the air leaves the desiccant container 14, enters the regeneration conduit device 12e, and is then fed into the one-way valves 20a, 20b, and 20c. As they are opened by the regeneration air, the air passes through them and enters the second connection device 18, after which it flows into the atmosphere.

[0068] According to the present invention, an air treatment device for a multi-purpose vehicle is also provided, which has at least one of the above-described air dryer devices 10.

[0069] The air handling unit includes an air dryer unit 10, a control valve unit for controlling the operation of the air dryer unit (e.g., regeneration and loading phases), and a multi-loop protection valve unit.

[0070] Other units or modules, such as parking brake unit, trailer control valve unit and / or maintenance brake unit, can also be integrated into the air handling unit.

[0071] according to Figure 1 Arrows and / or arrow portions not associated with reference numerals do not contribute to the subject matter of the air dryer device 10 and air treatment device according to the invention.

[0072] Figure 2 The invention is shown according to the following: Figure 1 A schematic cross-sectional view of one embodiment of the one-way valves 20a, 20b, and 20c of the air dryer device 10.

[0073] according to Figure 2 An exemplary first check valve 20a is shown, wherein the following description of the structure and function of the first check valve 20a and its related technical teachings are also applicable to [the following text is incomplete and requires further context to translate accurately]. Figure 1 The second and third check valves 20b and 20c.

[0074] Therefore, the second and third check valves 20b and 20c are formed in the same manner as the first check valve 20a.

[0075] according to Figure 2 The first one-way valve 20a is composed of a valve body 22.

[0076] The valve body 22 is formed as an integral elastic valve body.

[0077] In particular, the valve body 22 can be formed as an integral elastic rubber valve body.

[0078] The first one-way valve 20a is also formed by a valve housing portion 24, which is integrally formed with the housing socket 12 of the air dryer housing 12.

[0079] The valve housing 24 includes a valve inlet 24a, which is connected to the regeneration conduit device 12e.

[0080] Accordingly, the valve housing 24 includes a valve outlet 24b, which is connected to the second connecting device 18.

[0081] The valve housing 24 is formed as a circular hollow cylinder and protrudes from the housing inlet 12a in the direction opposite to that of the desiccant container 14 (see...). Figure 1 ).

[0082] The valve housing 24 also includes a centrally located mounting area for securing the valve body 22 within the valve housing 24.

[0083] The inner surface 24c of the valve housing 24 is formed as a circular sealing surface.

[0084] The valve body 22 includes a diaphragm portion 22a, which is divided into a horizontal inner portion 22b and an inclined outer portion 22c.

[0085] An inclined hardening section with a large cross-section is arranged at the transition section 22d between the horizontal interior 22b and the inclined exterior 22c.

[0086] A radial sealing lip 22e is arranged at the outermost radial position of the inclined outer side 22c. This radial sealing lip maintains a sealing contact with the inner surface 24c of the valve housing portion 24 in the installed state.

[0087] Alternatively or additionally, the valve body 22 may also include an axial seal (not shown).

[0088] It can also be imagined that the axial seal is integrated into the radial sealing lip 22e.

[0089] Alternatively, the axial seal can be formed as a separate part of the valve body 22.

[0090] The valve body 22 also includes a resiliently compressible and expandable fixing part 22f, which is formed as a hollow cylindrical fixing pin.

[0091] The valve body 22 also includes an axially fixed surface that maintains contact with the corresponding wall surface of the mounting area.

[0092] The axial internal fixing surface is formed by the horizontal interior 22b of the valve body 22 and the fixing cover 22g, which is arranged at the axial end of the fixing pin opposite to the horizontal interior 22b of the valve body 22.

[0093] The fixed cover 22g also includes two guide chamfers so that the valve body can be properly installed by pushing the valve body into the mounting hole in the mounting area only in the mounting direction with the two guide chamfers facing forward.
