Abstract

1423479 Valves UNITED STIRLING (SWEDEN) AB & CO 6 May 1974 19736/74 Heading F2V In a piston valve cylindrical surfaced PTFE sealing ring 16 backed by rubber ring 17 have an axial dimension greater than that of passageways 10 in the piston 3. The piston has a cavity 9 from which lead two sets of radial passageways 10, 11 which provide the means for interconnecting the passageway 4 with the passageway 5 or 6. Fluid pressure within the cavity 9 when the valve is in use provides a fluid cushion between the surface of the piston and the surface of the sealing ring 16 which prevents the latter being damaged as it slides relatively to the passageway openings 10, 11. Alternatively some or all of the seals may be mounted on the piston 3.
