Abstract
A power steering system has a power assist for the steering gear of an automotive vehicle. The power assist comprises a piston reciprocable in a cylinder. Hydraulic fluid is delivered to opposite sides of the piston by a control valve. A pressure line delivers hydraulic fluid to the control valve from a pump. A return line returns hydraulic fluid to a pump reservoir. An anti-rattle device provides a restriction in the return line to suppress the transmission of noise and vibrations from the road travelled through the steering gear to the steering wheel.
