Title: Improvements in or relating to centrifugal or other roto dynamic pumps
Inventor: PECK JOHN FREDERICK
IPC: F04D15/00
Filed: 1962-09-12
Abstract: 986,700. Priming centrifugal &c. pumps. GOODENOUGH PUMPS Ltd. June 12, 1963 [Sept. 12, 1962], No. 34853/62. Heading F1C. The casing of the centrifugal pump shown is initially filled with water. When the impeller 18 is rotated, water returns from the discharge chamber 30 to the suction pipe 8 via a tube 32 and a bypass 35, and entrains air from the suction pipe 8 and extension pipe 10 as it enters the impeller eye 28. The air tends to separate out from the water and be discharged through the pump outlet 6 while the main bulk of the initial charge of water stays in the pump casing and is continuously recirculated. On completion of priming, the discharge pressure, communicated through a passage 40 to the left-hand side of a flexible diaphragm 36, reaches its normal value and moves the diaphragm against the action of a spring 42 to close the end of the tube 32 and stop the recirculation of fluid. Since only a small central area of the right-hand face of the diaphragm 36 is exposed through the tube 32 to the discharge pressure, the remainder of this face being exposed through the passage 35 to the suction pressure, while the whole of the left-hand face is exposed to the discharge pressure, there is a net force holding the diaphragm against the end of the tube 32 during normal operation of the pump. A filter may be provided between the discharge chamber 30 and the end of the tube 32 adjacent the diaphragm to remove solid particles which might prevent the diaphragm from seating properly on the end of the tube. The diaphragm may be replaced by a piston working in a cylinder. The Provisional Specification describes an arrangement in which the priming device is separate from the pump and is connected to the latter through pipes.

Patent GB-605112-A (GB)
Title: Means for controlling the flow of liquid fuel to prime movers
IPC: F02C7/22
Filed: 1945-12-27
Abstract: 605,112. Fluid-pressure servomotor-control systems. LUCAS, Ltd., J., and IFIELD, R. J. Dec. 27, 1945, No. 34919. [Class 135] [Also in Groups XXVI and XXVII] The flow of liquid fuel from a variable delivery pump to the nozzles in a combustion chamber of a prime mover is controlled by passing the fuel through a valve and a variable orifice, regulating the pump delivery by the pressure drop set up across the orifice and varying the orifice in response to air blower pressure, and controlling the valve by manually adjustable and temperature responsive means. In an embodiment, fuel delivered by a variable swashplate pump a flows into the controlling device through an inlet r past a valve 6 and a restriction u and out through s to the burners n. Valve 6 is loaded by a spring 34 and is actuated through a lever 36, tappet 37 and a cam surface 38. The latter is carried by a plunger 39 which can be rotated manually by a lever 43 so as to set the valve according to the desired temperature of the hot gases in the combustion chamber, or the plunger can be reciprocated longitudinally due to its screw and nut connection with a piston 49 which is acted upon by fluid in a chamber 50 connected to a feeler bulb responsive to the temperature of the air supplied to the combustion chamber. In a modification, the connection between piston 49 and plunger 39 is by means of a cam lever. In parallel with orifice u is an orifice formed between a screwed plug x and a hollow cylinder v, the fuel being supplied to this orifice past an adjustable needle valve 5 and through apertures 8 in the cylinder v. The fuel pressure on the downstream side of the orifices is applied to the interior of a bellows 20, and the fuelpressure on the upstream side is applied through a passage 25 to the exterior of the bellows. Resultant movements of the bellows are transmitted through a lever 21 to a valve 22 which vents the right-hand end of a cylinder 29 containing a servo-piston 26 connected to the swash-plate of the pump. The output pressure of the pump is applied to the lefthand end of the servo-cylinder 29 through a passage 31, and to the right-hand end past a restriction 30. Cylinder v carries a piston y, the underside of which is subject to the pressure of the inlet liquid flowing past needle valve 5 and this liquid also flows to the upper side of the piston through a restriction 9. Movement of piston y, and hence variation in the size of the two orifices, is controlled by a valve 11 venting the chamber on the upper side of piston y, this valve being carried by a bell-crank 12 which is acted upon by two bellows 13, 14 of which the former is evacuated and the latter is subject to blower pressure. Movement of piston y is also communicated to lever 12 by a spring 2. Specification 577,016 is referred to.
