ABSTRACT:
In order to enable only condensate to be discharged/fed under pressure without leaking out steam independently of the respective pressures at the primary side and at the secondary side, in a condensate discharging device comprising a condensate receiving chamber provided with a condensate inlet opening and a condensate outlet opening as well as an operating high pressure fluid inlet and outlet; a float disposed within the chamber and adapted to rise and drop along with the water level; an inlet valve connected to the float and used for opening and closing the inlet; an exhaust valve connected to the float and used for opening and closing the outlet; and check valves, one arranged at the condensate inlet opening and the other at the condensate outlet opening, the improvement comprises a valve mechanism connected to the float to open and close the outlet opening independently of the check valves, the valve mechanism being adapted to close the condensate outlet opening when the water level is low, and to open the condensate outlet opening when there is a rise in the water level, whereby after the float closes the inlet (8) and opens the high pressure fluid outlet the condensate is introduced from the condensate inlet opening into the chamber until the water level reaches a predetermined water level, and the high pressure fluid outlet is closed and the high pressure fluid inlet is opened, the condensate thereby being discharged from the opened condensate outlet opening when the predetermined water level is reached.
