摘要: The invention concerns a pressure reduction valve (1) with a housing (2a, 2b), a valve element (6) being displaceable in the housing and acted upon in one direction by a pressure in a low-pressure chamber connected with an outlet (11) and in the opposite direction by the force of a spring (16), which is arranged in a spring chamber (17) in the housing (2a). It is endeavoured to improve the dynamic behaviour of the pressure reduction valve. For this purpose, a pilot flow path (7, 23, 21) connects the low-pressure chamber (5) and the spring chamber (17) with each other.

摘要: The invention concerns a hydraulic valve arrangement (1) with a supply connection arrangement comprising a high-pressure connection (P) and a low-pressure connection (T), a working connection arrangement comprising two working connections (A, B), which can be connected to a motor (4), a directional valve arrangement (5) located between the supply connection arrangement (P, T) and the working connection arrangement (A, B), and a compensation valve (15) acted upon in a first activation direction by a pressure in a first pressure chamber (33), which is connected to a load-sensing pipe (LS), and, if required, by a spring (32), and in a second activation direction opposite to the first activation direction by a pressure downstream of the directional valve arrangement (5), said pressure acting in a second pressure chamber (34), the compensation valve (15) having an inlet (14) and an outlet (19). In connection with a post-compensated valve, it is endeavoured to adjust the load pressures at the working connections (A, B) in dependence of the direction. For this purpose, each working connection (A, B) is connected to a control system, which amplifies the effect of the pressure in the first pressure chamber (33) on the compensation valve (15) in dependence of a pressure ruling at the working connection (A, B).

摘要: The invention concerns a hydraulic steering with a steering initiator, a steering unit with feedback properties, which can be activated by the steering initiator, the steering unit having a supply connection arrangement with a pressure connection (P) and a tank connection (T) and a working connection arrangement with two working connections (L, R), an auxiliary-force operated steering valve, which is located in parallel with the steering unit between the supply connection arrangement (P, T) and the working connection arrangement (L, R), and a feedback suppressing device, which is active, when the steering valve is active. It is endeavoured to find a simple manner of ensuring the priority of the steering initiator over the steering valve. For this purpose, the steering initiator interacts with an activation sensor, which deactivates the feedback suppressing device on an activation of the steering initiator.

摘要: A hydraulic vehicle drive, particularly for mobile hoisting platforms, has a first pair of wheels drivable by first wheel motors in dependence of a first control valve and a second pair of wheels provided with second hydraulic motors. A switching arrangement short-circuits the second hydraulic motors in the driving-free state and for cooling supplies them with a flushing flow. In the driven state a second control valve, in dependence of which the second hydraulic motors are drivable, is activated, and if required connected with the first control valve. Thus, optionally, the first wheel pair can be driven alone or together with a certain driving output from the second wheel pair.
