Abstract

PURPOSE:To improve the efficiency of this pump, by mounting two diaphragms, which effective areas differ, into housings, which are oppositely arranged, in spit- like shapes, by supplying a drive fluid to a primary chamber and by generating discharge pressure to a secondary chamber. CONSTITUTION:The first and second diaphragms 3a, 3b, 4a, 4b, which effective areas differ, are disposed into the housings 2a, 2b of both ends of a main shaft 1 in spit-like shapes, thus forming primary chambers 11a, 11b, to which a fluid for drive is fed by means of the first and second diaphragms 3a, 3b, 4a, 4b, atmospheric air chambers 10a, 10b communicated with atmospheric air and secondary chambers 12a, 12b, which generate discharge pressure boosted. A sleeve spool type direction change-over valve 7 and a pilot operation valve 8 are arranged in parallel with the main shaft 1.
