Abstract

1,145,283. Centrifugal pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 22, 1966 [May 27, 1965], No. 22526/65. Heading F1C. A pump suitable for supplying fuel to I. C. engines, comprises a first stage impeller 9, Fig. 1, discharging through a pair of inclined inlets 16 to a second stage impeller 12. The latter is housed in a chamber 11 having a pair of diametricallyopposed tangential outlets 14 and a side channel 19 divided by fixtures (18), Fig. 2 (not shown), into two semi-circular channels each extending between a respective inlet 16 and outlet 14. At a predetermined speed the semi-circular side channels are closed by an annular piston 20 moved, against the action of springs (23) and the average pressure in the channels, by communicating pressure from relatively high-pressure regions of the channels to the right-hand side of the piston through restricted passages (21) in the piston. With the channels closed the pump operates as a normal centrifugal pump.
