Abstract

The invention relates to an electromagnetic valve device having an armature (18) which is moveable in an axial direction in a valve housing (10) in response to energizing of a stationary coil (12), and which is designed to interact with a first valve seat (22) associated with a fluid inlet connection (26) of the valve housing, a first fluid flow path (36) being formed in the valve housing such that fluid flowing through the opened first valve seat can flow in order to actuate a plunger (32) moveable relative to the armature (18) and to which a preloading force is applied, the actuation causing 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 the valve housing having a fastening structure (44, 46) in the form of at least one hole extending at an angle to the axial direction, the fluid inlet connection (26) and the working connection (42) being formed on the same axial side of the valve housing in relation to the structure means.

First claim

and the actuation causing 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 the valve housing having 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 a same axial side of the valve housing in relation to the fastening means,
wherein
the fastening means is assigned an additional fluid connection ( 50 ) of the valve device the additional fluid connection is permanently connected to the fluid inlet connection, the additional fluid connection ( 50 ) being formed and oriented relative to the fastening means, wherein a plurality of electromagnetic valve devices are connected to each other by the fastening means.

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 2 , wherein the mechanical restoring force is a spring-loaded ( 40 ) restoring force.
