Abstract
The bimetallic plates of the steam trap disclosed each comprise three same-direction active arms next to one another extending transversely to a center line. On the center line two active arms extend in opposite directions to one another and transversely to the other active arms. On the side of the bimetallic plates which curve concavely when deflected there are provided projections as support portions or faces for the active arms. The projections of at least two active arms project beyond those of the other active arms. The projections of the active arms come into effect at different temperatures and with accumulative force. The bimetallic plates therefore have a closing force line closely adapted to the saturated steam curve.
