Abstract

An electromagnetic valve device having a fluid inlet port (1), which is formed in a valve casing (10), for a fluid to be switched, in particular pneumatic fluid, a working port (2), which is realized in the valve casing, for the fluid and locking component(s) (14), which are moveably guided in the valve casing along an axial direction and which are realized for interacting with a valve seat (26) formed in the valve casing and opening a fluid flow path between the fluid inlet port and the working port and which are moveably realized via fluid switched by means of electromagnetic positioning means (32).

First claim

1 . An electromagnetic valve having a fluid inlet port ( 1 ), which is formed in a valve casing ( 10 ), for fluid to be switched,
a working port ( 2 ), which is formed in the valve casing, for the fluid, and locking means ( 14 ), which are movably guided in the valve casing along an axial direction and are formed for interacting with a valve seat ( 26 ) formed in the valve casing and opening a fluid flow path between the fluid inlet port and the working port and which are realized so as to be movable via a fluid switched by means of electromagnetic positioning means ( 32 ), an axially directed drive force of the drive means counteracting a return force acting on the locking means via spring means ( 36 ), wherein the valve seat ( 26 ) is formed axially bilaterally such that a first opening area is exposed in a first axial displacement position of the locking means relative to the valve casing and a second opening area, which is arranged opposite to the first opening area, is exposed in an opposing second axial displacement position, and the module-like valve casing being used and received in a valve outer casing ( 50 ) having external ports, which align with the fluid inlet port as well as the working port, such that when the positioning means are not activated, the return force closes the fluid flow path in the valve outer casing at least partially surrounding the valve casing when in a first receiving position of the valve casing (NC, FIG. 1 ), and when the positioning means are not activated, the return force keeping the fluid flow path open in a second receiving position of the valve casing in the valve outer casing (NO, FIG. 3 ), in contrast to the first receiving position, the second receiving position intending a changed mounting and relative position of the valve casing in the valve outer casing, in particular tilted by 180° in the valve outer casing in a plane extending perpendicular to the axial direction.

2 . The device according to claim 1 , wherein the module-like valve casing ( 10 ) comprises an outer contour, which is cylindrical at least in sections and is realized for fittingly interacting with valve outer casing ( 50 ) realized like a hollow cylinder at least in sections.

3 . The device according to claim 1 , wherein sealing means ( 42 ; 43 ), realized as a sealing ring extending inclined, are intended in or on an outer jacket surface of the valve casing in such a manner that the sealing means seal the fluid inlet port and the working port from each other, in relation to an inner surface of the valve outer casing, when in the first and the second receiving position.

4 . The device according to claim 3 , wherein the sealing means ( 43 ) are realized as polymer and/or rubber-elastic components and are fastened on or in the valve casing in a fixed manner.

5 . The device according to claim 1 , wherein the electromagnetic positioning means override a fluid pressure, which acts on the end of an axial front section of the stretched locking means, in the make of a pilot command valve ( 52 ).

6 . The device according to claim 1 , wherein ducts ( 20 , 22 ), which extend radially at least in sections and realize a section of the fluid flow path to the valve seat, connect to the fluid inlet port and/or the working port in the valve casing realized as a plastic injection molded part.

7 . The device according to claim 1 , wherein a fluid flow path is realized such in ducts of the valve casing that the working port ( 2 ) is open to the first and the second opening area.

8 . The device according to claim 1 , wherein the valve casing is realized as a component group formed integrally from a plastic material and forming the fluid inlet port, the working port, the first and the second opening area as well as connection ducts.

9 . The device according to claim 1 , wherein the valve casing comprises an aeration port ( 3 ) as an additional valve port which can be connected to the fluid inlet port or the working port by the additional valve port being switched by being displaced.

10 . A usage of the electromagnetic valve device of claim 1 as a pneumatic valve pilot-controlled via the electromagnetic drive means and/or provided with a booster technology enlarging a nominal size and/or an effective pressure cross section.

11 . A system having a plurality of the electromagnetic valve devices according to claim 1 , whose respective fluid inlet ports ( 1 ) are connected to each other so as to conduct fluid, the connection being realized via a transverse bore ( 70 ) allocated to each valve casing, extending transversally to the axial direction and installed for being coupled to each adjacent valve device.

12 . The device according to claim 4 , wherein the sealing means ( 43 ) are realized as polymer and/or rubber-elastic components and are fastened on or in the valve casing in a fixed manner as a result of a multi-component injection molding process.
