Abstract

1,175,694. Valves; shaft seals. A. STERMER. 8 Dec., 1966 [20 Dec., 1965], No. 55079/66. Headings F2B and F2V. An axially movable stem 7, 8 extending be. tween two zones 1, 3 at different pressures is sealed by a pair of diaphragms 11, 12 the former of which underlies a plate 2 through which the steam passes and has a bellows-like central portion enclosing a part of stem portion 8. Diaphragm 11 may alternatively be of smaller external diameter and be secured to plate 2. The stem is connected by disc 10 to a member 5 which may comprise a valve element. The arrangement minimizes thrust on the stem by the pressure difference.
