摘要： A hydraulic control arrangement (1) is described having a directional valve (2), a metering pump unit which has at least two metering pumps (3, 4) which are connected hydraulically in parallel and are operable mechanically in parallel, and a shut-off valve (6) in hydraulic connection between two of the at least two metering pumps (3, 4), a pump connection (P) and a tank connection (T) which are connected to said metering pump unit by way of the directional valve (2), and two working connections (L, R) connected to the directional valve (2), a control input (8) of the shut-off valve (6) being connected to the pump connection (P) by means of a control valve. Such a control arrangement should be operated at a high hydraulic pressure and at the same time it should be made sure that the shut-off valve is actuated only when the required high pressure is available. To this end the control valve (10) is a pilot operated valve, an inlet (11) of said control valve (10) being connected to the pump connection (P), said control valve (10) connecting said input (8) and said pump connection (P) in an actuated state of said control valve (10).

摘要： The invention provides a steering system e.g. for a vehicle. The system comprises a system-pump, a steering actuator, a rotary valve, a rotary meter, and a motor. The system-pump is arranged to provide a flow of a fluid to the steering actuator via the rotary valve and via the rotary meter, and the motor is arranged to provide rotation of the rotary valve and the rotary meter. To handle an emergency situation if the system-pump fails, the motor is dimensioned to operate the rotary meter as a fail-operational pump for pumping a flow of the fluid to the steering actuator if the system-pump fails.

摘要： The present invention is to prevent a sub-pump from being unnecessarily operative in a normal operating state, and to effect steering assist when an engine stops. When a main pump is operative in a normal state, oil in an oil tank is supplied to a pump switching valve in a power steering unit via a main feed passage, and a power cylinder (123) and a power cylinder (13) effect steering assist for wheels by use of the oil from the main pump. In case an abnormal operation occurs on the main pump or an oil pressure decreases due to an damage on the main feed passage and the like, a pressure detecting switch detects it and sends an On-signal to a drive control unit. The drive control unit that receives the On-signal then supplies a battery voltage to the sub-pump to drive the sub-pump. The oil in the oil tank is supplied to the pump switching valve in the power steering unit via a sub-feed passage, and the power cylinder is activated to effect steering assist for the wheels.
摘要翻译：本发明是为了防止副泵在正常运行状态下不必要地工作，并且在发动机停止时实现转向辅助。当主泵在正常状态下工作时，油箱中的油通过主进给通道供给到动力转向单元中的泵切换阀，动力缸（123）和动力缸（13）通过使用来自主泵的油辅助车轮。如果在主泵上发生异常操作或由于主供给通道等上的损坏导致油压降低，则压力检测开关将其检测并将该信号发送到驱动控制单元。接收接通信号的驱动控制单元然后向副泵提供电池电压以驱动副泵。油箱中的油通过副进给通道供给到动力转向单元中的泵切换阀，并且动力缸被启动以实现车轮的转向辅助。

摘要： A hydraulic steering arrangement includes a steering valve, a steering motor, connected with a high-pressure connection and a low-pressure connection via the steering valve, and with a steering unit, connected via the steering valve with a pilot pressure valve, whose outlet is connected with the low-pressure connection. It is endeavoured to improve the steering behaviour. For this purpose, the pilot pressure valve is opened, before the steering valve creates a connection between the high-pressure connection and the steering motor.
