Abstract
PURPOSE: To automatically conduction between the casing inside and the reservoir in response to the needs in such a way that a shut-off plate and an inlet plate which have their tapered surfaces and inlet ports are provided in the bottom of the casing, and the inlet plate is forcibly pushed unidirectionally by a spring.
CONSTITUTION: A shut-off plate 27 and an inlet plate 24 which have respectively tapered surfaces and inlet ports 43, 26 are provided in the bottom part of a casing 41. Thus, when the pump apparatus is lifted up for the purpose of repair or another, since the inlet plate 24 gets rid of the empty weight of the pump apparatus, it moves in the right direction, and conduction between the inlet port 26 and the inlet port 43 is shut off by a shut-off rim 25. While the shut-off plate 27 is lifted up by the movement of the inlet plate 24, and a packing 29 closely sticks to the lower end surface of a stopper surface part 30. In consequence, conduction between the casing inside and the reservoir can be automatically and accurately shut off.
