Abstract
A thermostatic steam trap having a balanced pressure thermostatic element (2,2A,2B) operated by volatile fluid (15) is disclosed in which an internal void (10) of the element is open to steam/condensate within the trap, and in which the volatile fluid fills a housing (6) outside the element when the trap is fully open thereby to support the element against high pressure within the element. In the trap fully-closed condition the element adopts a nearly nesting condition so that if the element is then subjected to higher pressure externally it adopts a fully nesting condition in which it can withstand great external pressure.
