In a discharge device for a condensate operative within a given temperature range, and including a housing, a valve seat disposed in the housing, a closure part cooperating with the valve seat and subjected to an inlet pressure, a bimetallic snap disc carrying the closure part, being supported in the housing, subjected to the inlet pressure, and moving towards the valve seat upon an increase of temperature within the temperature range, the improvement includes an entrainment device carried by the closure part and connected to the bimetallic snap disc, wherein the closure part and the bimetallic snap disc define a central axis, and the closure part is movable along a path defined by the axis relative to the bimetallic snap disc, the bimetallic snap disc has an opening snap stroke, a closing snap stroke, and a snap stroke portion common with the opening and closing snap strokes, and exerting in a predetermined region a force in a closing direction, and wherein the valve seat is disposed within the predetermined region and within the common snap stroke portion.

Discharge device for a condensate controlled by a bimetallic snap disc

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.
