摘要： The invention relates to a control valve unit (9) for a variation device of a hydrostatic piston engine. The control valve unit (9) comprises a valve housing (34), in which a valve element is disposed in a longitudinally displaceable manner. The valve element is adjustable from a neutral position in the direction of a first end position and an oppositely directed second end position. With increasing adjustment of the valve element a first or a second output port (35a, 35b) is increasingly connected to an input port (12). The respective other output port (35b, 35a) is at the same time increasingly connected to a relief line (13). The valve element comprises a first valve piston (32a) and a second valve piston (32b), which act upon one another via an elastic element (27).

摘要： The invention relates to an electromagnet for actuating a valve. To this end, the electromagnet (28) comprises an armature (58), which can be axially displaced in an armature space (57, 77) and whose axial motion displaces a tappet (29) to the valve. The electromagnet is provided with reflux channel (71.1), which is connected to the armature space (57, 77) and via which the armature space (57, 77) is connected to a tank volume (25) in order to lead away a pressure medium leakage flow that is flowing out of the valve and into the armature space (57, 77).

摘要： A pressure-control valve (1) comprises a first control piston (1), which is disposed between a first pressure chamber (6), which adjoins the first control piston (1) and is connected to at least one working line (A, B), and a second pressure chamber (7), which adjoins the first control piston (1) and is pushed against a stop (3) by a first preloading spring (4). A throttle (8) connects the first pressure chamber (6) and the second pressure chamber (7). The second pressure chamber (7) is connected to a second control piston (11), which is preloaded by a second preloading spring (17) and which, when a predetermined pressure in the second pressure chamber (7) is exceeded, is displaced to an extent such that a control edge (12) of the second control piston (11) clears a connection of the second pressure chamber (7) to a hydraulic fluid discharge point (23). The first control piston (1) comprises a control edge (2) which connects an actuating pressure line (5) to a hydraulic fluid discharge point (23) when the first control piston (1) is displaced against the first preloading spring (4). An actuator (15), which is regulated by a control signal, presses onto the second control piston (11) against the second preloading spring (17).
