    摘要: A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.

    摘要: Disclosed is a method of manufacture or adjustment of an electromagnetically drivable actuator, which is appropriate for controlling the flow of a fluid, such as a hydraulic or pneumatic analog valve or an analogized switch valve (10). The actuator has an electromagnetic arrangement that is drivable by an exciter coil (12) having at least one movable armature (6). The electromagnetic arrangement acts mechanically upon a valve actuating device for opening and closing the actuator. The valve actuating device has a closing element (5), a resetting element (9) for opening or closing the closing element when the exciter coil is not excited, and one valve seat (4) into which the closing element engages. According to the method, the properties of the valve are adjusted by insertion of a spacer element (1). The spacer element (1) allows at least displacing a stop of the resetting element in an axial direction corresponding to the armature movement. Also disclosed is an actuator that allows implementation of the method.
