ボイラ―や廃熱利用装置へ排出される。When the working fluid inlet 11 is opened, high-pressure steam is introduced into the closed vessel 2 and the internal pressure increases,
The condensed water collected in the liquid storage space 10 is pushed by the vapor pressure and discharged from the pumping liquid discharge port 17 to an external boiler or waste heat utilization device via a check valve (not shown).

The rotation of the arm 34 in the counterclockwise direction causes the suppression member 4 to rotate.
The right piece of 5 abuts against the reversing leaf spring 43, causing the reversing leaf spring 43 to bend in a “reverse S” shape, thereby reversing the reversing leaf spring 43. Then, the reversing leaf spring 43 comes into contact with the left piece of the spring receiving portion 46 formed on the sub arm 42 via the left piece of the relaxation member 48, and the sub arm 42 rapidly rotates clockwise to rotate the shaft. 47 rapidly moves downward. As a result, the lifting rods 24 and 31 connected to the shaft 47 move rapidly downward, and the air supply valve 20 is closed and the exhaust valve 21 is opened.

装置。1. A closed container having a working fluid inlet, a working fluid outlet, a pumping liquid inlet, and a pumping liquid outlet has a float, a switching valve, and a snap mechanism built therein. A first axis supported within the first arm; a float arm rotating about the first axis; and a first arm supported in the closed vessel at a point away from the first axis. A second axis parallel to the axis, a sub-arm rotating about the second axis, a spring receiving portion formed on the float arm, and a spring receiving portion formed on the sub-arm Portion, a reversing leaf spring disposed between the two spring receiving portions, a suppressing member for suppressing the curvature of the reversing leaf spring and reversing the reversing leaf spring, and between the sub arm and the reversing leaf spring. A cushioning member arranged to resiliently relieve the impact of the reversing leaf spring; Is connected to the float arm, and the switching valve is connected to the sub arm.
