Abstract
The steering of a motor vehicle is assisted by a power steering means including a hydraulic distributor which is supplied with pressurized fluid by a pump from a reservoir. The vehicle also has a clutch having hydraulic servo assistance supplied by a servo unit. The distributor of the power steering system and the clutch servo unit are both supplied with hydraulic fluid from the same pump and reservoir, through a distribution unit which is so arranged that the power steering system has first call at all times on the available pressurized fluid. The distributor unit includes a flow distributing valve, fed from the pump and dividing the flow between a main circuit which leads to the steering distributor, and a secondary circuit which leads to the servo unit. A pressure regulating valve is connected to both the main circuit and the secondary circuit so as to regulate the pressure in each of these circuits according to the demand of the power steering system.
