ABSTRACT:
A steam trap has a control member which includes a bimetallic element at the prepressure side and a locking element, which is biased by the prepressure in an opening direction relative to a valve seat provided for the locking element. The bimetallic element is supported at one end on an abutment and it actuates the locking element with its other end. At least one snap spring which is supported on the abutment is effective on the control member in the direction of the locking element stroke axis, and it has a spring constant which is numerically larger than the spring constant of the bimetallic element.
