Zusammenfassung:	A valve assembly having a plurality of coaxial disposed bores, a central one thereof being slightly enlarged in diameter and accommodating a plurality of ring inserts for cooperation with a number of thin disc valve members each carrying an O-ring seal in a rectangular peripheral groove. The valve assembly includes at least two ports communicating with the enlarged interior bore on opposite sides of the annular ring insert, and at least one axial aperture extends through the side walls of the groove of the disc valves to enable release of pressure otherwise existing under the O-ring seal.
