Abstract
There are disclosed steam traps for use, for example, in a steam system for expelling large quantities of condensate fluid at low pressures and for self locking closed at pressures above a predetermined pressure. The traps include a chamber having an input port and an output port. A movable piston blocks fluid flow between the input port and output port at high pressures but moves to an unblocking position at low pressures to permit fluid flow through the traps.
