Abstract
The present invention relates to a hydraulic power steering system for automotive vehicles, having a steering gear with housing, steering shaft and steering rack, a hydraulic cylinder coupled to said steering rack, a pump and a steering valve, with all individual parts of the steering system forming a pre-assembly unit. This does not only permit a "just-in-time" delivery of the completely assembled, fluid-filled and tested system to the car maker, but also eases disassembly when the vehicle is junked. Thus, the power steering system according to this invention is inexpensive and can be recycled in an environment-friendly manner. The invention also includes a noise and vibration damping mounting arrangement. Still further, the invention includes an electric pump assembly.
