Abstract

1,263,057. Diaphragm pumps. T. J. F. ROACH. Feb.6, 1969 [Feb.22, 1968], No.8713/68. Heading F1A. In a diaphragm pump the diaphragm component 3 is disposed between a main section 1 and a flanking section 2 and comprises a single sheet of flexible material, such as rubber, incorporating a non return flap valve 38, 39 across the inlet and outlet of the pump; a beading (41) Fig. 4 (not shown) surrounding the diaphragm area engaging with a corresponding groove forms a seal between the main and flanking sections. The beading may be formed on the sheet or on the main and/or flanking sections. Similar beadings (42) may surround the area of the sheet constituting the flap valves 38, 39. In another embodiment a double acting pump, Fig. 5, has the main hollow section 50, chambered flanking sections 2, 2<SP>1</SP> and diaphragm components 3, 3<SP>1</SP> provided on each side. The pump may be manually operated by the lever (4) Figs.2, 6 (not shown) or alternatively the bolt 33 may be electrically or mechanically driven, for example by an eccentric driven by pneumatic or hydraulic means.
