Abstract

PURPOSE: To obtain highly reliable enclosing function without subject to the aging and to simplify the structure, by using not a spring but the weight of a pump and a cover to perform the passing and blocking of the liquefied gas.
CONSTITUTION: When using a pump 10 it is suspended in a casing 4, and when the large diameter section 35 of the pump 10 is engaged with a pump engaging section 36 it is supported by the casing 4. When the pump 10 is lowering, a suction bell 34 is contacted against a rod 29 to lift the cover 28 by the weight of the pump 10 thus to release the engagement between the cover 32 and the frange 32 and to lead the liquefied gas from the liquefied gas storage tank into the suction bell 34. When driving the pump 10 under this condition, the liquefied gas is transferred through the pump 10 to predetermined position. While when the pump 10 is suspended upwardly, the cover 28 will move downwardly by the weight to engage the cover 32 with the frange 33 to block the flow of the liquefied gas. Consequently the enclosing function of casing having high reliability and simple structure can be achieved.
