Abstract

A diaphragm type pumpe device comprises a connect­ ing rod (1), a diaphragm (2) connected to an end of the connecting rod, a cover (13) which firmly secures the outer circumferential part of the diaphragm and constitutes a first operation chamber (14), a frame (19) which opposes the cover to firmly secure the outer circumferential part of the diaphragm (2) in association with the cover (13) and constitutes a second operation chamber (20), and an intake port (15; 21) and a discharge port (16; 22) which are respectively communicated with the first operation chamber (14) and the second operation chamber (20) and provided with check valves (17, 23; 18, 24) each having different communicating direction, wherein the first and second operation chambers (14; 20) alternatively perform pumping operation by the amplitude movement of the diaphragm (2) due to a combination of the reciprocating movement of the connecting rod and the action of the check valves.
