Abstract
A hydraulic power steering system which includes a tank and a power steering pump which takes in a pressure medium from an intake area which is decoupled from the prevailing atmospheric pressure on the side of the tank wall and delivers it under pressure to the power steering system. A valve device builds up a pre-pressure in the intake area and prevents a negative pressure and a positive pressure from building up on the interior of the oil tank.
