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

  • the electromagnet; and

    a thrust pin coupled to the electromagnet and axially movable along a first axis defined by a center of the thrust pin in such a way that a control piston of the central valve is axially displaceable along a second axis defined by a center of the control piston in a central valve housing by the movable thrust pin contacting the control piston,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;

    wherein the thrust pin is configured such that relative movement between the thrust pin and the control piston generates a relative movement of the first axis in relation to the second axis that causes a contact surface of the control piston to move along a front face of the thrust pin; and

    wherein the thrust pin is arranged and configured such that, during operation, the first axis of the thrust pin undergoes relative movement with respect to the second axis in a circular path at an intersection of the first axis and the contact surface of the control piston.
