Abstract: A supply device for the supply of pressure fluid into at least one vehicle brake or into a pressure fluid accumulator, wherein a piston is movably arranged in an accommodating member, a carrier bears a non-return valve arranged coaxially to the piston for the purpose of ventilating a working chamber into which the piston plunges, and wherein a resetting spring is arranged between the carrier and the piston. A multi-piece cage facilitating inserting the resetting spring into the cage parts, the cage parts comprise a fastener that locks the cage due to relative displacement of the cage parts, and the resetting spring is caged and simultaneously elastically preloaded under the relative displacement of the cage parts.

Abstract: A vehicle steering system for motor vehicles has a steering handle operable by the driver and connected to steerable vehicle wheels in terms of effect to determine a direction of driving. The vehicle steering system includes a hydraulic working cylinder having two directions of effect, as well as a hydraulic pressure source, which applies hydraulic pressure to a valve assembly. The valve assembly controls the magnitude of the hydraulic pressure conveyed to the working cylinder and determines the direction of effect of the working cylinder. The valve assembly has two separated valves, the first valve determining the direction of effect of the working cylinder, while the second valve controls the working pressure for the hydraulic working cylinder.
