Abstract

464,877. Gear pumps. BRISTOL AEROPLANE CO., Ltd., and PONTING, R. Feb. 26, 1936, No. 5789. [Class 110 (ii)] A number of gear pumps is arranged in series, each stage being about 90 per cent. of the volumetric capacity of the preceding stage. Byepass valves 27, set to open at a pressure intermediate between the inlet pressure to a stage and the delivery pressure of the succeeding stage, allow surplus fluid to pass to a conduit leading to the inlet port of the first stage pump. Partitions 16 have conduits 17 leading from a delivery chamber of one stage to the inlet chamber of the succeeding stage.
