Abstract:
A flow control valve, particularly an electromagnetic proportional directional flow control valve (1), has a valve housing (2), in which a control piston (3) is guided to be displaced axially. The control piston (3) actuates at least one fluid-conducting connection (4) between a fluid inlet (5) and an outflow opening (6). An actuator part, in particular an armature (8), can be actuated by an actuator, particularly a proportional magnet, and acts on the control piston (3). A pressure detecting piston (9) serves for the action of the actuator part on the control piston (3). The fluid inlet (5) is connected in a fluid-conducting manner by a pressure detecting channel (11) to a pressure detecting chamber (12) such that the fluid pressure prevailing in the pressure detecting chamber (12) loads the pressure detecting piston (9) and the control piston (3) with a force (F) in the direction of relief of the actuator, and a further fluid-conducting connection (4′) between the fluid inlet (5) and a further outflow opening (6′) is actuated.
