Abstract

1,234,921. Diaphragm pumps. T. H. BAGGALEY. Jan. 5, 1970 [Jan.6, 1969], No.806/69. Addition to 1,117,516. Heading F1A. The fluid operated diaphragm pump of the parent Specification is modified in that the <SP>"</SP> diaphragm is constructed from two membrances 9, 10 separated by a spacer 14, the face of the membrane 10 bounding the pumping chamber 21 being of smaller area than the face of the membrane 9 subjected to the operating fluid in a passage 19. O-ring 30 and is urged by a spring 32. A similar arrangement of valves is provided on the delivery conduit 23, 40. The space between the membranes is vented to atmosphere through a passage 46 closed by a plug 47 having a restricted passage.
