摘要： A directional control valve includes a housing with a pressure inlet port, two working ports and a vent port with one working port directly connected to the vent port and the other working port communicating with the vent port via a control piston. The control piston includes a sliding valve in the area of one working port and a seat valve in the area of the other working port. A throttle bush rotatably arranged in the housing and a throttle screw rotatable relative to the throttle bush cooperate with the control valve to modify and throttle separately and independently from each other the cross sectional ventilating areas for the working ports.

摘要： A height adjustment device of a vehicle seat comprises a control valve means for governing the degree of filling of a compressed air actuator. Following an alteration in the weight to be carried by the compressed air actuator there is a relative switching over movement between a component bearing a control cam slide and a component bearing an actuating member entailing the switch over of the control valve means. The relative switching over movement is a linear movement, the two components bearing the slide and the actuating member being guided for relative sliding linear motion in the direction of the switch over movement. Furthermore a vehicle seat having such a height adjustment device is provided.

摘要： A directional control valve for compressed air with an inlet port, at least one consumer port and at least one vent port includes a housing accommodating a control piston for controlling the connection between the inlet port, the consumer port and the vent port, and a one-way restrictor arrangement. The one-way restrictor arrangement is fitted directly within the housing between the vent port and the consumer port, transversely to the longitudinal axis of the control piston. In this manner, a flow of compressed air to the consumer is prevented upon occurrence of a dynamic pressure.

摘要： The invention relates to a pressure regulating valve for pneumatic and hydraulic pressure media wherein a higher primary pressure is regulated to a desired lower secondary pressure. The valve comprises a primary connection, a secondary connection and a relief connection, there being a switch valve between the primary connection and the secondary connection, a relief valve between the secondary connection and the relief connection, and a control connection for controlling the operation of the valve in response to an external controlled quantity. The controlled quantity may be the secondary pressure output of the valve, or may be another pressure or a mechanical displacement of a larger system.

摘要： An impulse valve has a housing provided with a working chamber and a main piston movable in the working chamber; two preliminary control valves are electromagnetically operated for a short period to switch over the main piston into a selected switching position which is retained even if the preliminary control valve is deenergized. To reduce volume of the valve and to reduce manufacturing cost, a flexible diaphragm is arranged between the preliminary control valves and the main control valve and cooperates with two opposite valve seats in such a manner as to establish connection between an inlet port to the working chamber and alternatively to pressure-relieve the working chamber.

摘要： A two hand safety control mechanism for a consumer actuated by pressure medium includes a safety valve blocking the supply of pressure medium during a faulty switching and venting the consumer. For maintaining a working position of the consumer, a plurality of control valves are provided which are dynamically self-regulating. By actuating a further control valve, the automatic retention can be cancelled in order to allow the consumer to return in its idle position.
