The bimetallic plates (10) of the steam trap each comprise three samedirection active arms (17 to 19) extending transversely to the centre line (20) next to one another on either side of a centre line (20). On the centre line (20) there are provided two active arms (23) which extend in opposite directions to one another and transversely to the other active arms (17 to 19). On the side with concave deflection of the bimetallic plates (10) there are provided projections (27 to 30) as support faces for the active arms. The projections (27) of at least two active arms (17) project beyond those (28 to 30) of the other active arms (18, 19, 23). The projections (27 to 30) of the active arms (17 to 19, 23) come into effect at different temperatures and with accumulative force. The bimetallic plates (10) therefore have a closing force line well adapted to the saturated steam curve.
