PROBLEM TO BE SOLVED: To provide a liquid pressure feeding apparatus capable of preventing re-evaporation of condensate inside a sealed container and capable of quickly opening a flow-in side check valve when an exhaust valve is opened and an intake valve is closed. SOLUTION: An intake valve 20 is provided in an operating vapor introduction port 11, and an exhaust valve 21 is provided in an operating vapor discharge port 13. A flow-in side check valve 66 is provided in a liquid flow-in port 16, and a pressure-feeding side check valve 67 is provided in a liquid discharge port 17. A float 3 and a snap mechanism 5 are built in a sealed container 2. The snap mechanism 5 has a float arm 51, an auxiliary arm 52 and a coil spring 54. The sealed container 2 is provided with a cooling water filler 18 and a water filler valve 19 having a water filler valve element 63 for opening/closing the cooling water filler 18, and the water filler valve element 63 is coupled to the auxiliary arm 52. The water filler valve 19 is opened when the exhaust valve 21 is opened and the intake valve 20 is closed, and the water filler valve 19 is closed when the exhaust valve 21 is closed and the intake valve 20 is opened.
