ABSTRACT:
A hydraulic system for a motor vehicle is provided with a pump suction enhancer includes a body section defining a small chamber, a venturi tube passage exposed to the small chamber at an inner end thereof and connected to the suction port of the oil pump, and a nozzle protruding into the small chamber to face the inner end of the venturi tube passage with a space relative to the venturi tube passage in axial alignment with the same. The flow divider divides the operating oil discharged from the oil pump into a return flow to the pump suction enhancer and a supply flow which passes through a power steering device to return to an oil reservoir. The pump suction enhancer may be integrally formed with the oil reservoir or provided as a discrete component separated from the oil reservoir, oil pump and the flow divider.
