Abstract

PURPOSE: To prevent leakage of liquid from a tank by constituting a pump so that the liquid level in a large vessel lowers when the pump is operated and liquid is flowed out by syphon effect and that when the liquid level reaches a small hole part in the air introducing passage which is in alignment with a single aperture formed in the pump part, air flows in and stops the syphon action.
CONSTITUTION: Wheh liquid is dispensed from a polyethylene vessel having the capacity of, for example, 20l to a container having the capacity of, for example, 5l or more by means of a pump, the liquid level in the vessel which conforms the height in a suction pipe 4 is confirmed in the state of the suction pipe 4 inserted completely into the large vessel, and the small hole 11 of the pump part A is aligned with the air introducing passage 9 having a first lower small hole 12a or the subsequent small hole 12b. Accordingly, when the pump is operated, and the liquid level in the large vessel lowers as a result of the flowing-out of liquid due to syphon effect, and reaches the position of the small hole 10 on the air introducing passage 9 which is aligned with the only one small hole 11 in the pump part A, then, air flows into and the syphon effect stops automatically, and the leakage of liquid from the tank is prevented.
