Abstract

PURPOSE: To make easier priming injection operation at the time of self-suction operation as well as facilitate molding synthetic resin in pressure chamber by forming a water-feeding path hanging down inside pressure chamber in such a way that it is exposed to the outside by piercing the priming cup.
CONSTITUTION: The check valve chamber 6 is provided at upstream side of the casing 4 in which the impeller 2 is housed and also the synthetic resin-made pressure chamber 10 to form the vapor-water separating chamber 8 is provided at the downstream side of casing 4. In the pressure chamber 10, the water-feeding pipe 18 to form the water-feeding path 16 leading to pressure tank and water valve is provided in hanging manner coaxially with the priming cup 12 provided at the upper part of the pressure chamber 10 and the opening 20 leading to the vapor-water separating chamber 8 when the priming cup 12 is closed by the valve 14 is formed in such a way that it is exposed to the outside of the outer opening 22 of the priming cup 12. Thus, the priming operation can be easily made and also the molding of pressure chamber with a synthetic resin is made easier because of the easy concurrent rotary mold drawing of priming cup screw and the water-feeding pipe.
