ABSTRACT:
A double-acting, pneumatic, reciprocating diaphragm pump and reversing mechanism therefor including a pump housing including a pair of spaced apart chambers, a diaphragm member dividing each chamber into a driving section and a discharge section, a shaft interconnecting the diaphragm members and a protrusion extending from the shaft, fluid inlet and outlet manifolds interconnecting inlet and outlet ports, respectively, in the discharge sections and inlet and outlet valves in the housing for controlling fluid flow to and from the discharge sections, a driving fluid manifold interconnecting inlet-outlet port means in the driving sections, a control valve between the chambers including a valve element movable between two positions to alternately direct driving fluid to one of the two driving sections while also alternately venting the other one, a control valve accuating member mounted for movement and having means for contacting and moving the valve element and having surfaces for being contacted by the shaft protrusion, and snap-acting spring means connected to the valve actuating means for snap moving said valve actuating means which in turn moves said valve element.
