Description

 Electromagnetic valve device, use of such as well as valve system

The present invention relates to an electromagnetic Ventilvorrich- device according to the preamble of the main claim. Furthermore, the present invention relates to a use of such an electromagnetic valve device, and the present invention relates to a system comprising a plurality of such electromagnetic valve devices.

An electromagnetic valve device according to the preamble of the main claim is well known from the prior art and is used for various switching and control purposes, in particular in one embodiment as a pneumatic valve for motor vehicles (and there in particular in the commercial vehicle context). In the context of a conventional embodiment as a 3/2-pneumatic valve with three fluid connections and two switching positions thereby cause the anchor means, in otherwise known manner in response to a current flow stationary coil means in the valve housing relative to stationary core means, the switching of the valve fluid, wherein in the present generic Context so-called booster-assisted valves an additional gain functionality of the fluid circuit is realized. Specifically, in a generic manner, the movement of the anchor means activated by the energizing of the coil means causes the opening or closing of a first valve seat associated with the fluid inlet connection (pressure connection) of the valve housing. The opened first valve seat allows the incoming pneumatic fluid to enter a first fluid flow path, from where the fluid acts to actuate plunger means (also known as generically known) as essential components of a booster technology. In this case, the fluid pressure of the fluid flowing into the inlet connection overcomes a (for example by a Tension spring or the like force accumulator generated) counterforce of the plunger means and moves the plunger means until a second (previously closed by the plunger means) valve seat is opened. As a result, the fluid flow is then effected up to the fluid outlet connection (fluid working connection) of the valve housing.

Due to the fluid pressure requirements approximately in a motor vehicle environment and against the background of an increased effective (fluid) cross-sectional width, such, as generally known vorausgesetz- te booster technology for mechanical power assistance of electromagnetically actuated valves of the generic type has prevailed and proven.

However, about the used for interacting with the second valve seat plunger means require additional axial and radial space in the valve housing, which should be understood as "axial" in the context of the present Anmaltungsungstexte a direction of movement of the anchor means, which preferably an extension or longitudinal axis of the Due to cramped installation conditions, especially in a motor vehicle, there is a need for optimization and shortening, not least as a generic valve housing, next to the typically flange of the housing body before - Jumping fluid inlet and fluid outlet port, in addition fastening means are provided, which at least one opening, but typically a transverse to the axial direction extending bore pair of screws to be used for mounting purposes or the like. Together with the to the core and coil means (including an extern on the housing for energizing ansitzenden Connector section) required space so creates a resulting radial and axial extension, which is in need of optimization.

In genus-forming and thus generally known from the prior art Ventilvorrichtungen valve devices, it is also customary to provide the axial dimension optimization of a known valve housing, the plunger means geometrically in the axial region of the fastening means, it being known in particular, in a configuration of the fastening means as a pair mutually parallel mounting holes between them in the housing to receive the plunger means and to guide axially movable.

While such a known measure is favorable from the point of view of an optimized axial extent of the valve housing and causes a certain compactness, this also causes technical disadvantages: On the one hand limits the (usually standardized breakthroughs or standardized distances between the holes based) geometry of the fasteners an effective (maximum) transverse extent of the plunger means, so far as well as a usable for the booster effect attack surface of the fluid. On the other hand, such a solution requires that - again along the axial extension direction of the valve housing - the fluid inlet port and the fluid working port must be arranged on opposite sides of the fastening means, which in turn is geometrically unfavorable in terms of contour and size of the valve housing.

Object of the present invention is therefore to improve an electromagnetic valve device according to the preamble of the main claim in terms of their geometric and their functional properties, in particular an optimized (and thus for practice as wide as possible) transverse extension of the plunger means in the valve housing to allow in order to optimize the mechanical supportive effect of this booster technology without unnecessarily prolonging the overall axial extension of the valve body. In addition, the modularity of such a generic valve device is to be improved, in particular with regard to the mounting of a plurality of such devices (or the associated housing) to each other, so that, corresponding to more complex switching functionalities, with optimum overall compactness an optimized connectivity of the respective ports and the best possible ventilation behavior can be ensured.

The object is achieved by the electromagnetic valve device having the features of the main claim; advantageous developments of the invention are described in the subclaims. Additional protection within the scope of the invention is claimed for a use of the electromagnetic valve device according to the invention as a 3/2 pneumatic valve for switching and control applications in the motor vehicle sector, where the field of use of commercial vehicles is particularly preferred there. Finally, protection is claimed in the context of the present invention for a valve system, comprising a plurality of valve devices according to the invention, which are connected to each other by means of the respective fastening means realizing breakthroughs (and thus along the respective breakthrough extension directions) and so a compact, flexible and lightweight can form a mountable and reliable unit.

In an advantageous manner according to the invention it is provided that at or in a common axial end portion of the valve housing, axially adjacent to the core means (and, relative to the core means, axially opposite the anchor means) both a first vent outlet for venting one of the anchor means and the core means limited Anchor space is provided, and, adjacent to the first vent outlet, a second vent outlet for venting a movement space of the plunger means. This merging of the respective vents on the (typically narrow, frontally provided) axial end portion of the valve housing thus ensures that not only in a structurally and geometrically simple manner, a common valve housing section both venting realized (where preferred and further developing the invention, the first and the second vent outlet, more preferably in a common plane at the end portion, both separately from the valve body can escape, and may be merged as an alternative to a common vent outlet), and this measure according to the invention shifts the vent together with the necessary channels and outlets of one or both the spaces from a housing area of the fastening means or the booster ram means. In turn, according to the invention, this makes it possible, advantageously and further developing, to displace one of the fluid inlets, in particular and preferably, the fluid inlet connection according to the invention (typically connected as a pressure connection) into the region of the fastening means (which, preferably, as a pair parallel to one another and transverse to the axial direction extending holes or corresponding sleeves are realized).

It is advantageous and preferable on the one hand to arrange and align this fluid inlet connection according to the invention in the valve housing in such a way that it runs between the pair of apertures realizing the fastening means, at least with a connecting flange section which can be connected to the external pressurization. Alternatively, it is possible to provide the fluid inlet connection at an axial end section of the valve housing-axially opposite or opposite the first and the second vent outlet-so that, with a slim overall Housing contour, the best possible housing distribution and utilization is possible. In this case, a (stitch) channel coupling the fluid inlet connection to the housing-internal fluid guide channels would then run between the pair of mutually adjacent openings (bores) and in particular also axially or axially parallel.

In each of these (further developing) variants of the invention, the valve housing end section opposite the venting outlets is then advantageously uninfluenced by any venting functionality (and therefore makes possible these variants according to the invention). Rather, it is further provided according to the invention, for example, to guide a space leading to the movement of the plunger means vent channel axially spaced from the fasteners (and then typically kinkendend and weiterbildend coat inside the valve housing to the associated second vent outlet), more preferably even in sections parallel to the Breakthroughs of the fasteners, but not in an (axial) overlap area with these.

For further production optimization of the valve device according to the invention, the axial end section of the valve housing provided for the realization of the first and second vent outlet is designed such that there, as a separate component or separate module separate from the valve housing, advantageously forms or inserts a cover assembly may be, which (at least one) offers externally open fluid outlet opening for the first and the second vent outlet and, depending on geometric and space requirements, a fluid deflection of the exiting for venting fluid can cause. Further preferred and for a particularly simple production and assembly is such a cover assembly, as well as the valve housing, vorvor Partially made of a plastic material capable of injection molding by injection molding, sealingly insertable into a wall section of the valve housing (possibly with the interposition of a suitable, preferably around the deck assembly circumferentially provided seal), in which case this elongated and preferably radially circumferential wall portion suitable integrally from the axial End portion of the valve housing realizing plastic material is shaped out. Correspondingly, the lid assembly can be effected by simple (manual or mechanical) insertion or impressions, whereby then, with the desired venting outlet behavior of the fluid, the venting geometries can be optimized.

In order to realize these inventive and advantageous effects, it is structurally particularly favorable to vent the armature space delimited between the anchoring means and the stationary core means by a (more preferably axially extending) core bore, which still more preferably opens directly into the first vent outlet. In the manner described above, the movement space of the plunger means would then be vented through a deflected vent channel, which runs edge or shell side of the valve housing in this and at the axial end portion of the valve housing directly into the second vent outlet (preferably formed by the cover assembly, see above) , This obviously reduces the complexity of the channel guide in the valve housing, in particular in the region of the axial end section.

The inventively further developing and advantageous arrangement of the fluid input connection between the (preferably parallel) individual bores (sleeves) of the fastening means allows in a particularly simple manner the connection of a plurality of electromagnetic valve devices according to the invention on or next to one another, namely along a respective continuous direction of the bores (Breakthroughs): Not only would then namely, preferably in the form of continuous threaded rods or the like fasteners, such a cascade arrangement mechanically enable the housing connections, would also be in preferably further development of the first fluid input port as parallel to the openings extending bore, a fluid communication of Fluid input terminals of adjacent valve devices to be possible with each other; For possibly necessary sealing would then additionally advantageously further forming coupling agent or the like can be used. However, in order for such a valve device having a through hole to be used as a single component, in such a case, this (through) bore which forms the fluid inlet connection would be releasably or permanently closed at one end by suitable plugs or the like. This would also apply to a variant of the invention in which end-axial the fluid input port is provided (ie, extending from the valve housing opposite to the vent outlets). Here then, depending on the configuration of one or a plurality of devices, in each case openings which are not required and which are to be closed for proper functionality, should be sealed with corresponding plugs.

As a result, the present invention provides an optimized electromagnetic valve device, in which, not least by the inventive measure the displacement of both venting outlets to a common end or end side ("axial end portion") of the valve housing, the fluid inlet port to a opposite, opposite housing end or between the fastening means can be displaced, but not adjacent to the working port is provided (which, usually, still axially in the region of the plunger means laterally, ie in the radial direction, extending from the valve housing to the outside) Invention sees Rather, that the fluid input port, based on the fastening means, is no longer provided on the axial side of the fluid working port, so that in this respect, a further optimization of the valve housing is achieved.

According to the invention, the valve housing itself can advantageously be realized as a multi-part plastic casting housing, wherein it is additionally preferred according to the invention to realize the fluid inlet connection in the manner arranged according to the invention, to the working connection and the fastening means, more preferably as a pair of boreholes provided adjacent to one another or to provide in a one-piece housing part of such a valve housing. This then makes it possible, in particular, to additionally embed a booster functionality, for example in the form of the plunger means according to the invention, in this housing part, while the further electromagnet functionality, in particular the coil means together with stationary core means and suitable guidance of the anchor means, can be provided in a further housing assembly , which in turn then, more preferably integrally ansitzend, can accommodate a suitable connector portion for an electrical supply of the coil means. The two housing assemblies can in turn be structurally simple and manufacture technically low releasably or permanently connected during assembly.

A realized in the manner described above electromagnetic valve device is then preferably for a variety of, in particular pneumatic switching and control tasks in the automotive sector, in which case again defined the commercial vehicle technology preferred applications. However, the invention is not limited to such preferred use. Rather, the present invention is suitable for virtually any field of application in which, under limited construction conditions, dimensions, a connection, ventilation and a Befestigungsgeomethe the valve body are to optimize.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and the drawings; these show in:

Fig. 1, Fig. 2, Fig. 5 are perspective views of the electromagnetic valve device according to a first preferred embodiment of the present invention;

3 shows a longitudinal sectional view through the first embodiment;

4 shows a longitudinal sectional view analogous to FIG. 3, but rotated by 90 ° about the axial direction (which extends vertically in the plane of the figure);

6 shows a side view of the valve housing shown in perspective in FIGS. 1, 2, 5 of the first embodiment of the present invention; and

FIG. 7: a longitudinal section view analogous to FIG. 4, but running parallel to the sectional plane of FIG. 4 and through a fluid inlet connection realized as a continuous transverse bore.

The figures show various views and sections of the inventive electromagnetic valve device according to a first embodiment of the present invention. A valve housing 10 Hend from a (in the respective figure levels upper) housing assembly 10o for receiving a stationary coil unit 12 which is held on a bobbin 14 and electrically contacted via a on the housing assembly 10o ansitzenden male portion 16, and a lower housing assembly 10u, is to Receiving and guiding a vertical in the plane and thus formed in an axial direction armature unit 18 is formed. Specifically and in otherwise known manner, the drive of the armature unit 18, which is biased by action of a compression spring 20 against a first valve seat 22, which is normally closed, by energizing the coil 12 by means of contacts shown schematically in the connector portion 16. In an otherwise known manner, this energization leads to an upward movement of the armature 18 against a stationary core unit 24, whereby the nozzle-like first valve seat 22 is exposed. This is connected to a (typically with pneumatic fluid of a pressure in the range between about 10 and about 15 bar acted upon) fluid inlet 26 which at one (in the respective figure levels) bottom end portion of the lower housing assembly 10u (and thus the overall housing) between a pair of sleeve-like bores 44, 46 as a fastening means, provided and coupled via an axially parallel extending vertical channel 52 and a horizontal channel portion 53. In particular, the sectional view of Fig. 7 illustrates the passageway in the lower (ie fastener side) housing portion, Fig. 3 illustrates the further fluid guide to the valve seat 22nd

The solenoid valve of the first embodiment shown in the figures is provided with a so-called booster amplification technology, which is realized primarily by an axially adjustable ram unit 32, and which can be acted upon by the action of the described switching operation of the armature 18 with pneumatic fluid from the fluid inlet 26. Thus, when the armature 18 is energized (ie when the coil 12 is energized) and correspondingly exposed valve seat 22 - the sectional views of Figs. 3 and 4 show at one end of the anchor body 18 there inserted a sealing portion 34 of polymeric material - entering through the inlet 26 and passed through the channel assembly 52, 53 fluid through the open valve seat 22 and an adjacent Channel portion 36 act on a in the figure levels upwardly directed transverse surface 38 of the plunger unit 32. 4, biased by a compression spring 40 in an upward direction in the position of FIG. 4, the inflowing and 38 pending fluid pressure, however, exceeds the opposing force of the compression spring 40, so that by effect of the pneumatic fluid (still with the armature 18 tightened, ie upwardly against the core 24), the plunger 32 is moved downwards in the figure planes. This exposes a fluid flow channel guided from the channel section 36 to a fluid working port 42 via a second valve seat 43 opened by the plunger downward movement, so that in this operating state the pneumatic fluid can flow to the working outlet 42 protruding radially laterally from the lower housing assembly 10u. In addition, the relative arrangement of the fluid connection 26 as a fluid inlet connection on the one hand and 42 as a fluid working connection on the other hand becomes clear from the geometry consideration of the valve housing 10o, 10u: by the inlet connection 26, in the embodiment shown with its associated (and in the case of isolated use axially at one end by plug means or The same closable) bore axially parallel to the pair of mounting holes 44, 46 runs, the local, lower housing space is used as possible, not least as the pair of sleeve-like holes 44, 46 in a typically determined by external installation and dimensioning fixed distance to each other and so that otherwise unused space would open up. On the other hand, is located radially (transversely) to the axial direction outward pointing, the working port 42 (with a connector 41 shown schematically therein) axially at the height of the plunger means 32, but (again axially) spaced from the booster pressure input surface 38, so that in particular the booster design force not by a connection geometry of the working port is impaired.

It is also clear that the direction of the fluid operating connection 42 led out of the housing (more precisely, of the lower housing assembly 10u), relative to the axial direction, is orthogonal to the direction of the pair of fastening bores 44, 46 (and to the direction of the pressure port 26). runs. In accordance with the invention, the lower housing assembly 10u implemented in one piece and made of a plastic material also adopts or realizes both the fastening bores 44, 46 and the fluid connections 42 and 26, so that, if suitably used, then Booster assembly and subsequent assembly with the (preferably the solenoid valve technology preassembled having) upper housing assembly 10o, an efficient, potentially mass production suitable way for the production of the overall arrangement is created.

The illustrated in the figures first embodiment of the invention also illustrates how a limited between the core 24 and the armature 18 working space 54 (which then by the activated, ie when energizing the coil 12 upwardly moving armature 18 through one end thereon in the direction venting the core inserted polymeric sealing body 35 would be) is vented, in the direction of a first vent outlet 70, which exposes corresponding to the armature space 54 to the outside of the housing. Adjacent to the first housing outlet 70 in an upper housing end face ("axial end section of the valve housing") 72 is a second vent outlet 74, which is connected to the first housing outlet 70 Venting of a lower (ie axially pointing in the direction of the fastening means) movement space 76 of the plunger means 32 is used. More specifically, the plunger means 32, in the operating state of Fig. 3, Fig. 4, in de-energized state of the coil means 24 and corresponding pressurized fluid unenergized state of the transverse surface 38, the movement space 76 via a second development channel composite free, which is formed from a first transversely extending (and specifically realized as one end by means of a sealing ball 65 transverse bore) channel portion 64a, which then, in particular the longitudinal sectional view of Fig. 4, merges into a lower vertical portion 64b (edge or coat side extending in the lower housing assembly 10u ), which in turn then merges into an upper vertical section 64c (extending on the side of the casing in the upper housing assembly 10o), until this channel 64a, 64b, 64c opens into the front-side second vent outlet 74. In the described booster operation would then end-side polymer portion 77 of the ram unit 32, axia l opposite the surface 38, close the vent passage portion 64a. 3 and 4, the structural details of the geometric configuration of the axial end section of the valve housing for forming the first and the second vent outlet 70, 74 become clear: a cover-like plastic body 78, which is arranged in a circumferential direction, can be seen in particular. Fenden, end-side edge portion 80 of the upper valve housing assembly 10o is used (with sealant 81 for a corresponding edge-side and an underlying sealing washer 79 provide for a lower seal). In the exemplary embodiment shown, the lid body 78 is designed such that it continues, fluid-deflecting, the openings on the housing side of the ventilation channels 58 and 64c and exposes them to the outside of the housing. At the same time, in the exemplary embodiment shown, the structures thus formed remain The ventilation outlets are separated from each other. An alternative embodiment of the invention would open up the possibility that, either by the action of a correspondingly designed alternative cover assembly, alternatively by corresponding channel connection still in the end region of the actual valve housing, both venting channels could be brought together.

In elegant manufacturing technology, for example, the cover assembly 78 can be connected to the valve housing by (detachable) insertion, latching, clipping, alternatively insoluble by gluing, (ultrasonic) welding or the like connection method.

The present invention is not limited to the embodiment shown, but rather is exemplary. For example, it is also encompassed by the invention, in an alternative embodiment of the fluid input port 26, to orient and open it (alternatively or additionally) in an axial-bottom-side direction, for example in continuation of the channel (eg recognizable in the sectional view of FIG. 3) 32 in the direction of a bottom end of the valve housing. In this case, an external contacting with a suitable pressure hose or the like is made possible in a particularly simple manner.
