Abstract
A valve is provided of the type which includes a valve housing having a valve seat, a thermal control element mounted in the valve housing having a thin, rigid wall portion and a membrane member coupled peripherally with the wall portion, so as to define an expansion chamber therebetween in which an expansion medium is disposed and a locking member which is activated by the membrane for cooperative coaction with the valve seat. The valve is characterized by the provision of a valve housing having an inner chamber which substantially corresponds in size and shape to the outer configuration of the thermal control element. The inner chamber is provided with flow conduits disposed along the surface of the control element. The flow conduits are coupled to an inlet opening of the valve housing and an outlet opening defined by the opening of the locking member relative to the valve seat. The valve is especially intended for steam traps.
