Abstract

A sealing arrangement, which can be inserted into a recess formed in a valve housing, to effectively provide a fluid pressure seal between at least one input chamber and one output chamber, and in which a slide piston is movably-disposed in the recess. The sealing arrangement includes a first gasket and a second gasket, which are disposed in coaxial relationship to one another, and which are concentric to the recess of the valve housing. The two gaskets are connected to one another by means of elastic annular connecting pieces. The connecting pieces of the two gaskets are located between a plurality of apertured retaining elements, which have a portion of the end surfaces of projections in contact with the connecting pieces. A plurality of rivet members pass through the apertured retaining elements and the connection pieces to hold them in the form of a sealing cartridge.
