Abstract

An arrangement of an electromagnet (6) for controlling a central valve (2) is provided. A thrust pin (4) is coupled to the electromagnet (6) and can be moved along a first axis (A) in such a way that a control piston (1) of the central valve (2) can be displaced along a second axis (B) in a central valve housing (8) by the movable thrust pin (4). The first axis (A) of the thrust pin (4) extends parallel to and at a radial spacing (10) relative to the second axis (B) of the control piston (1).

Claims

1-6. -6. (canceled)

7. An arrangement of an electromagnet for controlling a central valve, the arrangement comprising:

the electromagnet; and

a thrust pin coupled to the electromagnet and movable along a first axis in such a way that a control piston of the central valve is displaceable along a second axis in a central valve housing with the aid of the movable thrust pin,

the first axis of the thrust pin extending in parallel to and at a radial distance with respect to the second axis of the control piston.

9. The arrangement as recited in claim 7 wherein, during operation, the first axis of the thrust pin describes a circular path on the contact surface of the control piston.

13. A combination of a central valve and arrangement of an electromagnet for controlling the central valve, the combination comprising:

a central valve having a control piston and a central valve housing;

an electromagnet; and

a thrust pin coupled to the electromagnet and movable along a first axis in such a way that the control piston of the central valve is displaceable along a second axis in the central valve housing with the aid of the movable thrust pin,

the first axis of the thrust pin extending in parallel to and at a radial distance with respect to the second axis of the control piston.
