ABSTRACT:
A steam trap is provided having a main locking member disposed in a supply pressure chamber and cooperating with a main valve seat, a pressure chamber provided in the low pressure end and an adjustment member mounted in the pressure chamber which is responsive to the pressure therein, and which is coupled with the main locking member by means of a shaft. The shaft has a control conduit longitudinally extending therethrough coupling the supply pressure end with the pressure chamber. A pilot valve seat is provided on the main locking member at the inlet opening of the control conduit and a pilot locking member is provided which cooperates with the pilot valve seat. An actuating device is provided for the pilot locking member which is controlled by the condensate to be discharged. The steam trap is particularly characterized by the provision of a seat element on which the main valve seat is formed which supports the pressure chamber on a neck member having outflow openings for the condensate. The pressure chamber housing is freely suspended in the low pressure chamber by the neck member.
