Abstract
A valve, in particular for use as a pressure compensator or maintenance-type component () in hydraulically actuated hoisting devices (), has a valve housing () with a control port (), a fluid inlet () and a fluid outlet (). A regulating piston () is longitudinally displaceably in the valve housing () and acts against an energy storage device () in the form of a compression spring, bringing the regulating piston () into positions forming a fluid-conveying connection between the fluid inlet () and the fluid outlet () or blocking this connection by a control pressure existing at the control port (). A first orifice () in the regulating piston () connects the control port () to a receiving space () for the energy storage device () in a fluid-conveying manner. A second orifice () is in an intermediate part () in the valve housing (). The receiving space () can be connected to a compensating chamber (), which connected to the fluid outlet () in a fluid-conveying manner ().
