Abstract
PURPOSE: To permit a worker to safely use a reciprocating pump which is actuated by compressed air even if it is immersed in water and smooth the actuation of a changeover valve body by eliminating the need for electrical parts in the pump section.
CONSTITUTION: A pair of pump chambers 1 in which an air inlet and outlet 2 is provided at the upper part and an intake port 4 with a backflow preventive valve 5 is provided at the lower part, respectively. A connection cylinder 7 connects between the mutual lower sections of rhe pump chambers 1 and an exhaust port 10 opens at the central part of the connection cylinder. A valve 8 which alternately opens and closes the intake port 4 is housed in the connection cylinder 7 and the upper part of each piston rod 13 of a piston 12 is connected to a connection lever 14 which swings taking the central part as a fulcrum. A changeover valve body 30 which switches the air flow passage from a compressor (not illustrated) into each pump chamber is provided and a spring 42 is inserted between the projection 15 of the connection lever 14 and a pin 40 which play-engages with the surface of the valve body 30.
