Abstract
A bimetal steam trap is disclosed, which includes a temperature-responsive valve arrangement and a bimetallic column formed of a plurality of pairs of bimetallic discs which are superposed with each other. The valve arrangement has a valve element normally biased by a spring toward its open position, which biasing force is overcome by the thermal expansion axial thrust generated by the bimetallic column when condensation temperature within the steam trap is above a predetermined level. To permit an axial displacement of the valve element in precise alignment with associated valve opening, an elongate valve member is provided at one end with the valve element, and serves to support the bimetallic column as an integrated sub-assembly.
