ABSTRACT:
A high pressure steam trap is provided of the type which has at least two serially-connected and operated discharge control assemblies which are switched in series in the flow direction of the condensate, each of which includes a thermal control element which is exposed to the condensate to be discharged, a valve seat, and a throttle element which is actuated by the thermal control element for movement relative to the valve seat. Expansion capsules serve as the thermal control elements and these capsules contain an evaporation liquid, the steam pressure of which, measured at the same temperature, is higher than the steam pressure of the evaporation liquid in the successively-disposed expansion capsules downstream therefrom.
