VALVES WITH REDUCED FLAT GROMMET HEIGHT

摘要

The invention concerns an improvement to the design of a tilting/gun valve, more particularly regarding the problem of sticking/blocking. The valve comprises a cup (5), a stem (10) with an enlarged circular base (21) end extending perpendicularly and, therebetween, a grommet (22) made of an elastomer polymer. The grommet (22) is provided with a flat lower surface extending essentially on all the flat upper surface of the enlarged base of the stem to secure the sealing effect. The grommet (22) height H below the cup is less than 4mm.
