Abstract

An electromagnetic valve device having an armature (18) designed such that it can move in an axial direction in a valve housing (10) in response to energising of a stationary coil (12) provided in the valve housing, and which interact with a first valve seat (22) associated with a fluid inlet connection (26) of the valve housing, wherein a first fluid flow path (36) is formed in the valve housing such that fluid flowing through the opened first valve seat can flow in order to actuate a plunger (32) provided axially or axially parallel to the armature (18) and moveable relative to same and to which a preloading force is applied, and the actuation causes a second valve seat (43) interacting with the plunger (32) to be opened to produce a fluid connection to a fluid working connection (42) of the valve housing, and wherein the valve housing has fastening structure (44, 46) in the form of at least one hole extending at an angle, to the axial direction, wherein the fluid inlet connection (26) and the working connection (42), provided adjacent thereto, is formed on the same axial side of the valve housing in relation to the fastening structure.

First claim

1. An electromagnetic valve device having armature means ( 18 ), wherein the armature means moves in an axial direction in a valve housing ( 10 ) in response to the energising of stationary coil means ( 12 ) provided in the valve housing, and interacts with a first valve seat ( 22 ) associated with a fluid inlet connection ( 26 ) of the valve housing,
wherein a first fluid flow path ( 36 ) is formed in the valve housing such that fluid flowing through the opened first valve seat can flow in order to actuate plunger means ( 32 ), wherein a preloading force is applied to the armature means,
and the actuation causes a second valve seat ( 43 ) interacting with the plunger means ( 32 ) to be opened to produce a fluid connection to a fluid working connection ( 42 ) of the valve housing,
and wherein the valve housing has fastening means ( 44 , 46 ) in the form of at least one hole extending at an angle to the axial direction wherein

the fluid inlet connection ( 26 ) and the working connection ( 42 ) are formed on the same axial side of the valve housing in relation to the fastening means, wherein the armature means in the valve housing are assigned stationary core means ( 24 ) axially opposite the first valve seat, wherein the core means together with the armature means delimit a ventilated working space ( 54 ), wherein the ventilation is implemented by a first ventilation path ( 58 ) which runs on and/or in the core means, a second ventilation path ( 64 ) which is defined entirely within the valve housing and runs at least partially parallel to the axial direction in the valve housing, and by a connecting path ( 62 ) which is formed at the end of the core means and/or of the valve housing and connects the first and second ventilation paths, and wherein the connecting path is implemented by means of a cap assembly and/or cover assembly ( 60 ) which can be connected to the axial end of the valve housing.

2. The device according to claim 1 , wherein a pneumatic fluid can be applied to the fluid inlet connection ( 26 ) in the form of a pneumatic pressure connection in such a manner that a fluid pressure of the pneumatic fluid can overcome a mechanical, restoring force acting on the plunger means ( 32 ) when the first valve seat ( 22 ) is opened.

3. The device according to claim 1 , wherein the fluid inlet connection and fluid working connection, which are each flange-like and sit as a single piece on the housing, are offset relative to each other in the axial direction and/or radially, and wherein the housing is at least partially cylindrical.

4. The device according to claim 3 , wherein the fluid inlet connection and fluid working connection are formed on mutually opposite sides of the valve housing in relation to a valve housing longitudinal axis corresponding to the axial direction.

5. The device according to claim 3 , wherein the fluid inlet connection and fluid working connection are formed on the valve housing adjacently, either without a radial offset or with a radial offset and an axial offset.

6. The device according to claim 3 , wherein a radial direction of the fluid inlet connection and/or fluid working connection, in relation to a radial direction of the hole of the fastening means, has an angle offset of zero or an angle offset in the range between 70° and 110°.

7. The device according to claim 1 , wherein the valve housing, in an end section axially opposite the fastening means, has a connector section ( 16 ) which can be connected a power supply of the coil means and has an orientation extending parallel to the fluid inlet connection and/or fluid outlet connection and/or at right angles an extension direction of the hole ( 44 , 46 ).

8. The device according to claim 1 , wherein the fastening means is assigned an additional fluid connection ( 50 ) of the valve device which is permanently connected to the fluid inlet connection.

9. The device according to claim 8 , wherein the additional fluid connection ( 50 ) is formed and oriented parallel relative to the fastening means, in such a manner that the respective additional fluid connections can be connected to each other in a pressure-tight manner, with the use of coupling means, when there is a plurality of valve housings, connected to one another by means of the fastening means, of a plurality of valve devices connected to one another.

10. The device according to claim 8 , wherein the fastening means have a pair of holes ( 44 , 46 ) formed adjacently to each other and oriented parallel to each other.

11. The device according to claim 1 , wherein the diameter and/or the maximum cross-sectional width of an actuation face ( 38 ) on the armature side of the plunger means ( 32 ), in relation to a centre axis spacing (b) of a pair of parallel holes ( 44 , 46 ) realising the fastening means is at least 0.4, and/or the diameter and/or the maximum cross-sectional width of the actuation face ( 38 ) on the armature side of the plunger means ( 32 ), in relation to a minimum radial distance (a) of the pair from the parallel holes ( 44 , 46 ) of the fastening means is at least 0.7.
