ABSTRACT:
A thermally-controlled valve for a steam trap and the like, includes a thermally-controlled element including generally plate-like outer and inner wall portions and a generally plate-like, resilient membrane member disposed between and welded at its outer edges to the wall portions. The outer wall portion and the membrane define therebetween a chamber for accommodating an expanding medium and a reciprocably movable locking member is disposed generally between the membrane member and the inner wall portion, and is disposed for cooperative engagement with the valve seat of the steam trap. The membrane member is coupled to the locking member to effect movement of the locking member relative to the valve seat, and is comprised of a plurality of superimposed membrane lamellae, which permits proper functioning of the valve under high operating pressures.
