PROBLEM TO BE SOLVED: To provide a condensate pressure feed device which can take away a condensate at the inlet port for working steam into a sealed vessel using a low-cost structure. SOLUTION: A sealed vessel 2 is provided with a working steam inlet port 15, steam exhaust port 16, pressure feed liquid inlet port 13 and liquid exhaust port 14, and incorporates a float 3, a supply valve 20 to open and close the steam inlet port, and an exhaust valve 21 to open and close the steam exhaust port, wherein the supply valve opens in accordance with the level of the liquid stagnating in the vessel, and the stagnating liquid is exhausted to outside the vessel from the exhaust port. In this liquid pressure feed device, a thermo- responsive element 25 to make displacement in accordance with the temp. change is coupled with the supply valve so as to take away the condensate at the inlet port into the vessel.
