Abstract
A valve for high-pressure radial piston pumps suitable for controlled brake systems. Prior art pumps consist of at least 5 elements. The valve includes less components and thus is less expensive to manufacture and easier to assemble. The valve's simplicity derives from the use of cold extruded connections between the valve and the housing, so that separate rubber sealings are superfluous, and which provide for a strong and non-detachable connection. Favorable embodiments of the present invention integrate some of the known valve elements thus reducing the number of the necessary cold extruded connections.
