PROBLEM TO BE SOLVED: To provide a liquid force-feed device capable of decreasing a flow velocity when a working fluid reaches a liquid level.SOLUTION: A liquid force-feed device 1 has a sealed container 2 provided with a working fluid inlet 11, a working fluid outlet 13, a liquid inlet 16, and a liquid outlet 17. A float 3 and a selector valve 4 are incorporated in the sealed container 2. Opening and closing of an air supply valve element 53 of the selector valve 4 for opening and closing an air supply valve port 50 of the working fluid inlet 11, and an exhaust valve element 47 of the selector valve 4 for opening and closing an exhaust valve port 51 of the working fluid discharge port 13 are switched according to upward/downward movement of the float 3. The exhaust valve port 51 is first opened and the air supply valve port 50 is closed to allow a liquid to flow in through the liquid inlet 16, then the exhaust valve port 51 is closed and the air supply valve port 50 is opened to force-feed the liquid accumulated in the sealed container 2 through the liquid outlet 17. A deflecting plate 55 directed in a horizontal direction is disposed at the air supply valve port 50 facing the inside of the sealed container 2, and an upward portion 65 directed obliquely upward is disposed on a tip of the deflecting plate 55. |
