Abstract
Description
Technical Field
[0001] The invention relates to a ventilation device, in particular to a ventilation device for use with at least one valve unit or a plurality of valve units, and to a brake system having such a ventilation device. Background Art
[0002] Trucks (LKWs) are usually equipped with pneumatic brake systems. The equipment units of such brake systems usually use pneumatic valves which discharge a volume flow outwards or toward the outside and thus toward the surrounding atmosphere, or have different active surfaces which need to be connected to the ambient pressure.
[0003] Usually, the valve discharges a volume flow to the outside in its switching position. In this case, the valve can have an internal active surface which should be at the level of the ambient pressure as constantly as possible. Therefore, such spaces, for example the space below the piston with the spring arranged therein, need to have a connection to the outside that is always open and are referred to as "breathing spaces".
[0004] The arrangement and orientation of the valves usually takes place in the vertical direction, so that for each valve the opening pointing downwards, ie in the direction of gravity, is suitable as a vent.
[0005] However, these ventilation openings have only low or no protection against water ingress, for example during cleaning with a high-pressure cleaner. Furthermore, in the case of complex appliance units of LKW brake systems, it is not always possible to arrange all valves in such a way, i.e. in the vertical direction, so that their ventilation openings are oriented accordingly. In this case, penetrating moisture or liquid cannot or cannot completely escape under the force of gravity. In particular, when the temperature drops below freezing, the remaining water freezes in the valves and blocks them. Summary of the invention
[0006] The object of the present invention is to develop a venting device of the type mentioned at the outset in an advantageous manner, in particular in such a manner that the penetration of moisture or liquid into the venting device can be at least substantially prevented or counteracted and the outflow of the penetrated moisture or liquid can be optimized, preferably in that the fluid connection prevents or reduces direct, straight penetration of water jets or the like by means of a deflection point, so that a venting function for a plurality of device units, such as valves, can be ensured. The object of the present invention is also to specify a brake system having such a venting device.
[0007] This object is achieved according to the invention by a ventilation system according to the features of claim 1 and a brake system according to the features of claim 11. Further advantageous embodiments are given in the dependent claims.
[0008] It is therefore provided to provide an exhaust device, which is particularly intended for use with at least one valve unit or a plurality of valve units, and which has at least one air chamber element, at least one outflow section and at least one first exhaust channel for forming a fluid connection between an outer side of the exhaust device and the at least one air chamber element, wherein the outflow section provides a fluid connection between the air chamber element and the at least one first exhaust channel. The first exhaust channel has a first opening and a second opening. The first impact surface is directed toward the first opening, and the second impact surface is directed toward the second opening, wherein the first impact surface and the second impact surface are spaced apart from the first opening and the second opening, respectively, in the direction of the first longitudinal axis of the first exhaust channel, and extend respectively across at least one cross section of the first exhaust channel, in particular across at least one cross section of the first opening and the second opening, respectively, so that a fluid connection between the first opening and the second opening and the outer side of the exhaust device is formed along at least one section of the first impact surface and the second impact surface, respectively.
[0009] The invention is based on the basic idea that exhaust gas with splash protection, in particular common splash protection for a plurality of (horizontally stacked) valves, can be provided. In this case, the exhaust gas device should in particular utilize the concept of a (common) exhaust gas space / (common) air chamber element with an outflow section arranged (vertically) below, which opens into an exhaust gas channel having an opening and having an impact surface respectively formed / arranged on the opening.
[0010] Furthermore, depending on the configuration and arrangement of the impact surface, at least one deflection point can be provided, so that the penetration of moisture or liquid in the direction of the first longitudinal axis of the first exhaust channel can be prevented and / or reduced. More precisely, the arrangement and configuration of the impact surface is provided such that, for example, a water jet intended to enter the first exhaust channel is deflected. The deflection or splitting or deflection of the water jet has the effect that the penetration of moisture / liquid deep into at least one air chamber element can be at least substantially prevented and / or reduced.
[0011] In addition, constructing the outflow section on the lower end of the air chamber element and the exhaust channel having the first opening and the second opening makes it possible not only to facilitate the outflow of moisture / liquid, but also to at least substantially prevent or resist the liquid from rising along the first exhaust channel and / or along the outflow section until it reaches the air chamber element.
[0012] Arranging the outflow section in a (vertically) lower position of the air chamber element within the meaning of the invention is to be understood in particular with reference to a suitable use and orientation of the exhaust system or a corresponding brake system. Due to the effect of gravity, moisture or liquid can escape or flow out of the air chamber element via the outflow section.
[0013] Venting of, for example, a plurality of valves (or valves) can be carried out via a common air chamber element of the exhaust device, which is formed by the exhaust device. The air chamber element is connected as a common space at a position located vertically below the valve to at least one outflow section pointing downward or to the side, so as to enable ventilation to the outside / towards the outside of the exhaust device.
[0014] In particular, the exhaust can be a so-called secondary exhaust, i.e. the exhaust of a valve such as a solenoid valve which only needs to discharge a small volume flow. In addition, exhaust can also be understood as connecting a "breathing space", such as a spring space or the like, to the (atmospheric) ambient pressure.
[0015] In the sense of the invention, the fluid connection is in particular provided as a connection for exhausting air. Thus, the fluid connection of the air chamber element to the first / second opening of the first exhaust duct and along at least a part of the associated impact surface can ensure that exhausting of, for example, a plurality of valves attached to the air chamber element can be carried out in a suitable manner.
[0016] Here, the opening of the at least one first exhaust duct allows penetrating moisture / liquid to flow out and / or at least substantially prevents the penetration of moisture / liquid into the air chamber element, in particular by avoiding (at least to the greatest extent possible) stagnation pressure in the at least one first exhaust duct and / or the outflow section.
[0017] Preferably, the openings can be formed at opposite ends of the first exhaust gas channel. Alternatively, the first / second opening can be formed along the first exhaust gas channel.
[0018] With the aid of the present invention, in particular with the aid of the impact surface and at least two openings in the exhaust duct, not only splash protection can be provided, but also an escape of penetrating liquid can be provided, in particular by avoiding or reducing stagnation pressure, thereby also making it possible to appropriately ensure a fluid connection from the air chamber element to the atmospheric outside of the exhaust device.
[0019] In the sense of the invention, the outflow section can in particular be an outflow opening, an outflow channel and / or the like, so that a fluid connection can be provided between the air chamber element and the first exhaust channel. According to the invention, the outflow section is arranged or configured at the lower end of the air chamber element.
[0020] An impact surface can be understood as a specially shaped surface and an associated (rounded) surface transition to an adjacent surface. In this sense, for example, a (rounded) surface transition can also be associated with a corresponding impact surface.
[0021] Furthermore, the first and second impact surfaces are spaced apart from the first and second openings, respectively, in the direction of the first longitudinal axis of the first exhaust passage and extend across at least one cross section of the first exhaust passage, in particular across the cross sections of the first and second openings, respectively.
[0022] In particular, the impact surfaces are arranged such that a fluid connection between the first opening and the second opening and the outer side of the exhaust system is formed along at least one section of the first impact surface and the second impact surface, respectively.
[0023] Depending on the spacing between the impact surface and the corresponding opening of the exhaust channel, a fluid connection can be ensured. The fluid connection has at least one turning point depending on the configuration of the impact surface and extends past a part of the impact surface into the exhaust channel. The fluid connection extends not only / exclusively in the direction of the (first) longitudinal axis of the (first) exhaust channel. Thus, splash protection can be provided depending on the impact surface.
[0024] Furthermore, the first exhaust passage may have a continuous or varying cross section along its first longitudinal axis. Preferably, the opening of the first exhaust passage has a constant cross section.
[0025] In the sense of providing splash protection or a turning point for the fluid connection, the impact surface is constructed at least with the size of the cross section of the exhaust channel or the corresponding first / second opening. In this way, it is possible to prevent the liquid from flowing / invading linearly into the exhaust channel only in the direction of the assigned longitudinal axis. In addition, it can be provided that the first exhaust channel merges into each second exhaust channel along its first opening and second opening and the first impact surface and the second impact surface. In addition, it is conceivable that the second exhaust channel has a third opening and a fourth opening, respectively, wherein at least one third impact surface is constructed in a manner that is spaced from at least one cross section of the second exhaust channel, in particular the cross section of the third opening, and is constructed across at least one cross section of the second exhaust channel, in particular the cross section of the third opening.
[0026] Preferably, the third opening and the fourth opening are respectively configured on opposite ends of the second exhaust passage. Alternatively, the third / fourth opening can be configured along the second exhaust passage.
[0027] In particular, the splash protection can be further optimized and supplemented by arranging or constructing a plurality of exhaust channels in such a way that the fluid connection between the outside of the exhaust device and the air chamber element has a plurality of turning points, which are constructed in particular by different impact surfaces in combination with the respectively assigned openings of the exhaust channels.
[0028] The first and second exhaust ducts can be oriented or arranged angularly offset from one another, preferably at an angle of approximately 90°, so that a turning point is formed along the transition between the first and second exhaust ducts. Furthermore, the first / second impact surface can be formed as part of the second exhaust duct or can be formed separately, as an additional element, in the region of the opening of the first exhaust duct.
[0029] Furthermore, it can be provided that no impact surface is formed in the region of the fourth opening. This allows for a more varied configuration of the exhaust gas channel, wherein there are no, at least no significant, disadvantages in terms of protection against moisture / liquid ingress due to the lack of a fourth impact surface.
[0030] Alternatively, the fourth impact surface can be formed in the region of the fourth opening or can be formed so as to point towards the fourth opening.
[0031] By means of the second exhaust gas channel, which is configured in series with the first exhaust gas channel, the intrusion of moisture or liquid can be prevented or reduced.
[0032] Furthermore, it can be provided that the first impact surface and the second impact surface are configured to be larger than the cross section of the first exhaust passage, in particular larger than the corresponding cross section of the first opening and the second opening. Furthermore, it is possible that the third impact surface is configured to be larger than the cross section of the second exhaust passage, in particular larger than the cross section of the third opening.
[0033] In this way, the intrusion of moisture / liquid in the direction of the longitudinal axis of the respective exhaust duct can be prevented. In particular, at least one turning point can be realized by extending the impact surface across the cross section of the respectively assigned opening or beyond the cross section, which can serve as a splash protection function.
[0034] Furthermore, it is conceivable that the impact surface is designed and arranged in such a way that the fluid connection between the air chamber element and the outer side of the exhaust system has a plurality of deflection points along the opening.
[0035] Preferably, at least one deflection point is provided in each case by means of the impact surfaces in such a way that the penetration of dirt, liquids (for example water) or the like can be prevented or reduced.
[0036] In particular, for example, a high-pressure water jet cannot penetrate directly into the exhaust duct, but is at least substantially deflected or split by means of the structural arrangement and the design of the exhaust opening with the impact surface within the exhaust system.
[0037] Furthermore, it is possible for the exhaust gas device to be designed in one piece or in multiple parts, in particular with a first side part and a cover element or with first and second side parts corresponding to one another and a sealing element arranged between multiple parts.
[0038] Thus, the exhaust device can have a first side part in the form of a structured body, which essentially has the air chamber element, and an unstructured cover element having a structure for closing the first side part.
[0039] Alternatively, the exhaust device can be configured to have a first side part and a second side part corresponding thereto, wherein the first side part and the second side part are each configured as a structured side part. The two side parts can have a symmetrical structure or an asymmetrical structure.
[0040] In this way, in particular the air chamber element, the outflow section and / or the first exhaust duct can be constructed in a symmetrically divided manner in both side parts or can be divided asymmetrically, for example in that the air chamber element is at least predominantly constructed in the first side part and / or the first exhaust duct is at least predominantly constructed in the second side part. With the aid of an optional sealing element between two components of the exhaust device, i.e. between the first side part and the cover element or between the first and second side parts, when water penetrates into the upwardly sealed common space, it is necessary to compress the air volume there in order to reach the valve or the structure to be exhausted.
[0041] In addition to the splash protection function (particularly by means of the impact surface) and the exhaust or outflow function (particularly by means of the opening of the exhaust channel), a fluid static / dynamic resistance against the intrusion of liquid into the exhaust device is thus provided.
[0042] In addition, it can be provided that at least one outflow section is configured at the lower end of the air chamber element in the vertical direction. In addition, it is conceivable that at least one outflow section is configured as at least one outflow opening or as at least one outflow opening combined with at least one outflow channel for providing a fluid connection between the air chamber element and the at least one first exhaust channel.
[0043] The outflow section is preferably arranged relative to or along the air chamber element in such a way that moisture / liquid can escape or flow away in the direction of the acting gravity.
[0044] In addition, the outflow section can be configured as an outflow opening connected to the outflow channel, preferably in the sense of an ascending channel. Therefore, intruding moisture or liquid (such as water) needs to rise along the outflow section against gravity to reach the valve or the structure to be vented.
[0045] Furthermore, it is conceivable that the venting device is designed to receive a plurality of valves which are fluidically connected to the air chamber element and to vent the valves.
[0046] In this way, central ventilation for multiple structures to be vented (eg valves) can be provided. The infrastructure for ventilation according to the invention can be easily adapted to the number of valves or structures to be vented, in particular by enlarging or reducing the air chamber elements.
[0047] In this sense, the air chamber element is a common space provided by the exhaust device, for example by a first and a second side part in combination with a sealing element arranged between the first and the second side part.
[0048] According to a further, parallel aspect, the invention relates to a brake system, in particular for a truck, which has at least one bleed device according to the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The outflow section 120, in particular the outflow opening 122, can be formed on the basis of the air chamber element 110. Figure 1 (in the vertical direction) of the lower side.
[0061] In particular, within the context of suitable use, the outflow section 120 can be formed on the vertical underside of the air chamber element 110 in order to allow moisture / liquid to flow away from the air chamber element 110 in the direction of the effective gravity force or to counteract the penetration of moisture / liquid.
[0062] according to Figure 1 The outflow channel 124 may extend in a substantially horizontal direction and may provide a fluid connection to the air chamber element 110 via the outflow opening 122 .

[0064] The outflow channel 124 may merge into a first exhaust gas channel 130 .
[0065] according to Figure 1 The exhaust passage 130 is configured to have a first opening 132 and a second opening 136 .
[0066] according to Figure 1 It is provided that the first opening and the second opening 132; 136 are formed at opposite ends of the first exhaust gas channel 130. Alternatively, the first / second opening 132; 136 may be arranged along the first exhaust gas channel.
[0067] The first / second opening 132 ; 136 is configured in conjunction with the first or second impact surface 134 ; 138 .
[0068] The first / second impact surface 134 ; 138 is arranged at a distance from the first / second opening 132 ; 136 , respectively, and extends across at least a cross section of the first / second opening 132 ; 136 .
[0069] In particular, the first / second impact surface 134 ; 138 is constructed and arranged to be spaced apart from the first or second opening 132 ; 136 in the direction of the first longitudinal axis X of the first exhaust passage 130 .
[0070] The impact surface 134 ; 138 can be designed in the exhaust system 100 or in the side part 150 as a wall section of the fluid connection or can be arranged as a separate surface in / along the fluid connection.
[0071] At least one deflection point is formed along the fluid connection which leads from the outside of exhaust system 100 and along at least a part / section of impact surface 134 ; 138 via opening 132 ; 136 into exhaust channel 130 .
[0072] Figure 2 A perspective view of a second exemplary embodiment of an exhaust system 100 is shown.
[0073] As in the first embodiment, the second embodiment of the exhaust device 100 can also be provided with a sealing element 170 (see Figure 2 ) or without an additional sealing element 170 (see Figure 2 1 and 1 . The first side member 150 is shown in the right side view of FIG.
[0074] The exhaust device 100 according to the present invention is Figure 2 The embodiment shown in FIG. 1 has an exhaust device 100 in Figure 1 The first embodiment shown in FIG. 1 has substantially the same structural features and functional features. Only the following structural and functional feature differences shall be explained:
[0075] In particular, according to Figure 1 Compared with the first embodiment, according to Figure 2 The second exemplary embodiment has a first exhaust gas channel 130 and a second exhaust gas channel 140 .
[0076] according to Figure 2 , the outflow section 120 is designed to have an outflow opening 122. The outflow opening 122 is arranged on the lower side of the air chamber element 110 in the vertical direction and in the direction of action of gravity.
[0077] A first outflow channel 124 is arranged or attached to the outflow section 120 .
[0078] according to Figure 2 , the first exhaust passage 130 may extend in a horizontal direction.
[0079] Additionally, the first exhaust passage 130 may have a cross-section that varies along the first longitudinal axis X.
[0080] Furthermore, the first exhaust gas channel 130 has a first opening and a second opening 132 ; 136 .
[0081] according to Figure 2 In the embodiment in FIG. 1 , the first opening and the second opening 132 ; 136 are arranged at opposite ends of the first exhaust passage 130 .
[0082] Alternatively, the openings 132 ; 136 may be formed along the first exhaust gas passage 130 .
[0083] In the region of the first / second opening 132 ; 136 , a first / second impact surface 134 ; 138 , respectively, is formed, in particular in the direction of the first longitudinal axis X in a manner spaced apart from the opening 132 ; 134 .
[0084] The first / second impact surface 134; 138 extends at least across the cross section of the first / second opening 132; 136, and is preferably configured to be larger than the corresponding cross section of the first / second opening 132; 136 respectively assigned. Figure 2 The first exhaust passage 130 transitions into the second exhaust passage 140 along the first / second opening 132 ; 136 .
[0085] The first and second exhaust passages 130; 140 are arranged angularly offset from each other, according to Figure 2 For example, they are offset from one another by an angle of approximately 90°.
[0086] In particular, two second exhaust gas ducts 140 are formed symmetrically to one another in the side part 150 .
[0087] The second exhaust passage 140 has a third opening and a fourth opening 142 ; 146 , respectively.
[0088] Furthermore, at least one third impact surface 144 is provided, preferably at a distance from the third opening 142 in the longitudinal direction or along a further longitudinal axis / second longitudinal axis of the second exhaust gas channel 140 .
[0089] according to Figure 2 , the fourth opening 146 may be configured without a fourth impact surface. Alternatively, the fourth impact surface may be arranged in the region of the fourth opening 146 .
[0090] The impact surfaces 134 ; 138 ; 144 can each be provided as a wall section of the fluid connection, for example in the first side part 150 , or can be provided as a separately constructed structure.
[0091] In addition, according to Figure 1 and Figure 2 Further impact surfaces can be provided along the fluid connection, for example in the region of the outflow opening 120 in the air chamber element 110 .
[0092] All impact surfaces can be designed as wall sections along the fluid connection or as separate structures, for example as convex surfaces within the air chamber element 110 and pointing toward the outflow opening 122 .
[0093] Figure 3 Show according to Figure 1 and 2 A perspective view of a third exemplary embodiment of an exhaust device 100 is shown.
[0094] like Figure 3 As shown, the first side part 150 of the exhaust device 100 can be closed by means of a cover element 160. Optionally, a sealing element 170 can be arranged between the cover element 160 and the first side part 150. Alternatively, in addition to the first side part 150, a correspondingly configured second side part can be provided.
[0095] The structure of the exhaust device 100, such as the air chamber element 110 and / or the outflow section 120 and / or the first / second exhaust channel 130; 140, can be constructed in a symmetrically distributed manner along the surfaces that should be arranged opposite to each other in the first / second side parts, or can be configured in an asymmetrically distributed manner in the first / second side parts.
[0096] It is therefore possible for the air chamber element 110 to be formed predominantly in the first side part 150 , wherein the first exhaust air duct 130 can be formed predominantly in the second side part.
[0097] The function of the exhaust device 100 can now be described as follows: Due to the outflow section 120 arranged (vertically) below along the air chamber element 110 , penetrating moisture / liquid can be discharged from the air chamber element 110 in the direction of the gravity acting during normal use.
[0098] Furthermore, it is ensured by the arrangement of the outflow section 120 , in particular of the outflow opening 122 , that liquid can only enter the air chamber element 110 in the vertical direction, wherein the air volume within the air chamber element 110 is compressed.
[0099] In particular, the structural arrangement of the outflow opening 122 represents a protection against the ingress of liquid into the air chamber element 110 and can counteract said ingress.
[0100] Furthermore, the ingress of liquid into the air chamber element 110 can be counteracted by the design of the outflow channel 124 in that the outflow channel 124 can be provided in the form of an ascending channel.
[0101] In the area of the opening 132; 136; 142 of the first / second exhaust channel 130; 140, the first / second / third impact surface 134; 138; 144 can perform a splash protection function, in particular, in that the fluid connection between the outside of the exhaust device 100 and the air chamber element 110 extends at least along the turning point.
[0102] The deflection points along the fluid connection can prevent water jets or the like from being able to penetrate directly into the exhaust system 100 in the longitudinal direction of one of the exhaust gas channels 130 ; 140 .
[0103] By deflecting or diverting the water jets by means of the impact surfaces 134 ; 138 ; 144 and the exhaust channels 130 ; 140 , an (unhindered) intrusion of moisture / liquid into the exhaust system 100 can be at least substantially prevented or counteracted.
[0104] Overall, with the aid of the ventilation device 100 according to the invention, advantageous ventilation of preferably a plurality of appliance units or valves to be ventilated can be provided.
[0105] In particular, a splash-proof function can be provided by means of the impact surface 134; 138; 144, wherein the exhaust unit 100 can at least substantially prevent or resist the intrusion of moisture / liquid, and the openings 132; 136; 142; 146 of the exhaust channel 130; 140 can facilitate, promote or support the flow away of the intruding moisture / liquid.
[0106] Furthermore, the outflow section 120 can be designed with an outflow opening 122 , in particular in combination with an outflow channel 124 , in order to counteract the rise of moisture / liquid into the (common) air chamber element 110 of preferably a plurality of appliance units / valves to be vented.
