Hydraulic power assisted steering system e.g. for motor vehicle, has steering cylinder which introduces power assisting force into steering mechanism and continuously connected to pressure chamber and tank chamber
The system has a steering cylinder (105) which introduces power assisting force into a steering mechanism (101) and continuously connected to a pressure chamber (107) and tank chamber (108) of a hydraulic circuit of a steering valve (106). The mechanism has a hydraulic pump (112) with an adjustable pumping volume in the pressure chamber in addition to a pressure tank (115) for hydraulic medium and a tank valve (121) located upstream from it in the pressure chamber. A release valve (122) is provided upstream from the steering valve to adjust the volume of flow in the pressure chamber. An independent claim is included for a method.
