Abstract
A valve is disclosed of the type which includes a thermal control element having at least one relatively thin rigid wall portion, a flexible membrane coupled to the periphery of the wall portion so as to define therebetween an expansion chamber in which an expansion medium is disposed, and a locking member which is actuated by the membrane for cooperative coaction with a valve seat. The valve is characterized by the provision of a relatively thick-walled, jacket-type housing which encompasses the control element in a supporting manner. The housing has flow conduits which oppose and run along the surface of the control element; the flow conduits being provided with an input and output opening for the medium to be discharged. The valve is particularly useful for steam traps.
