摘要： An electro-hydraulic arrangement regulating the lifting mechanism actuatable by a hydraulic motor, on an agricultural working vehicle having a driven wheel, comprises a plurality of sensors including a position sensor forming an actual value position signal, a force sensor forming an actual value force sensor, and an additional sensor forming an actual value slippage signal dependent on slippage of the driven wheel, a nominal value transmitter, a first summation point connected with the additional sensor and with the force sensor so as to obtain the slippage-dependent signal and the actual value force signal therefrom and to produce an output signal, a mixing device having a first input connected with the first summation point and for receiving the output signal and a second input connected with the position sensor for receiving the actual value position signal and producing an output signal, and a second summation point connected with the mixing device for receiving the output signal of the mixing device and also connected with the nominal value transmitter for receiving a signal from the latter so as to form a regulating deviation for the lifting mechanism.

摘要： A hydraulic control arrangement for regulating a lifting device in an agricultural vehicle has a proportionally operating regulating directional valve which includes a blocking unit, a control slider controlling said blocking unit and connected with a throttling valve so that its throttle slider during lifting operates as a pressure compensation valve and during lowering as a pressure reducing valve, and a spring associated with the throttle slider is only insignificantly stronger than the regulating spring in an adjusting device of an adjusting pump, so that during actuation of the throttle slider depending upon the high load pressure of a parallel-operating second hydromotor, the pressure differential required for the lifting stream at the control slider and the pressure differential acting during lowering in the first control conduit remain substantially constant.

摘要： A control arrangement for a hydraulic power consumer particularly in agricultural machines, has a pressure medium reservoir which is connected with a member for supplying pressure medium from the reservoir to the consumer to thereby move the consumer in one direction. The consumer is also connected with a member for withdrawing pressure medium from the consumer to thereby move the latter in an opposite direction. The arrangement further includes a single valve unit which is operative for both communicating and discommunicating the consumer with the supplying member and with the withdrawing member to thereby alternately move the consumer in the respective directions.
