VALVE SEAL

TITLE: VALVE SEAL A valve member for screw down valves or faucets, has a resilient "O" ring 26, 34, trapped in a recess by means of a central wedge, 25, 36, so that the "O" ring is squeezed between the wedge 25, 36, and the side wall 22, 33, of its containing cavity 21, 35, to thereby close off the cavity and securely hold the "O" ring in place. Passage of liquid into the cavity is minimised by the action of the wedge, and the provision of internal securing means 24, 38, so that the wedge is held from within the cavity by a threaded stud, 38, or snap-fit projection, 24, mating with a complementary recess 23, within the wedge.
