Abstract
1522468 Helico-centrifugal pumps SUNDSTRAND CORP 18 April 1977 [7 May 1976] 15987/77 Heading F1C Two diffusers 21, 22 are provided to receive the discharge from the pump impeller 16, the larger diffuser 21 being closed at low flow-rates by means of an axially slidable sleeve valve 23. Each diffuser comprises two volutes, approximately 180 degrees apart, discharging to an outlet pipe 26 in the case of the diffuser 21 and to an outlet pipe 29 in the case of the diffuser 22. The pump supplies fuel to an aircraft engine. When a high fuel flow-rate is demanded, the engine fuel control unit 48 supplies a pressure signal via a line 50 to shift a spool valve 47 to the left to admit fuel from the outlet pipe 29 to a chamber 37 to counterbalance the pressure within a chamber 36, whereupon the difference between the pressures acting on the ends 31, 30 of the sleeve valve 23 shifts the latter to the right to open the diffuser 21.
