Valve

Abstract

The present invention relates to the valve possessing the pump side [at least one] terminal area (10), the tank side [at least one] terminal area (14), the actuator side [at least one] terminal area (18), and the valve piston (22) displaced in a valve housing (12). The above-mentioned valve piston (22) separates the pump side terminal area (10) from the tank side terminal area (14) in at least one interception position, and acts mutually with an energy pooling machine (24). The fluid flow which flows between the actuator side terminal area (18) and the tank side terminal area (14) is controlled using a control device (26). The control device (26) is made as a fluid flow regulator included in the valve piston (22), and the above-mentioned fluid flow regulator, In contrast with the well-known valve which carried out diaphragm structure adoption, reduction with the steady value of the volume flow to an actuator is enabled in the way of having become independent of load, and that realizes load independent proportional control.
