Abstract: A hydraulic power steering apparatus has a piston pump operated by a steering wheel and shifting at an increased resistance, a control valve for connecting a motor driven power pump to a steering motor acting on the wheels of a car. An auxiliary motor is also connected to the wheels, and participates in normal steering operations, but when the wheels are jolted by the road surface, the increased pressure in the auxiliary motor effects shifting of a valve and thereby supply of pressure fluid from the power pump to the auxiliary motor for damping or compensating the jolt.

Abstract: A hydraulic conduit and a pressure vessel having an interior chamber provided with an opening cooperate with one another. A flexible partition subdivides the chamber into a first compartment which communicates with the opening, and a second compartment which contains a body of compressed gas which normally flexes the partition wall into the first compartment and against the opening. Connecting passages are provided which so connect the hydraulic conduit with the opening that hydraulic fluid flowing in the conduit is conducted in its entirety through the first compartment at least at such times as the flexible partition is out of contact with the opening.
