Title: Aircraft fuel pumping systems
IPC: B64D37/20
Filed: 1972-06-24
Abstract: 1417582 Centrifugal pumps ROLLS-ROYCE (1971) Ltd 9 March 1973 [14 March 1972 24 June 1972] 11803/72 and 29715/72 Heading F 1C An aircraft fuel pumping system comprises an impeller-type pump having a vaned diffuser in which the flow can comprise alternate slugs of liquid and gas, and a gas-liquid separator located downstream of the pump and having a liquid reservoir from which there is feedback to a point in the flow-path through the pump. An enginedriven aircraft fuel pump 18 receives fuel from an electrically-driven fuel pump located in the fuel tank and delivers it to a line 32 via a separator 16. Normally, any gas in the fuel is dispensed within it in the form of small bubbles. If, however, the bubbles amalgamate to form large bubbles each filling the fuel line locally, the resultant accumulation of gas in the upper part of the separator 16 causes the fuel level in the separator to drop until a valve 33 operated, e.g., by a float 40 opens, and the gas will then be vented via a line 34 when a relief valve 36 opens. Fuel fed back from the separator to the pump via a line 30 and a manifold 31 prevents loss of prime.

Title: Internal combustion engine with swash plate drive
IPC: F01B3/02
Filed: 1960-08-30
Abstract: 911,019. Driving gear; regulating. SCHWEIZERISCHE LOKOMOTIV-UND MASCHINENFABRIK. Aug. 30, 1960 [Sept. 3, 1959], No. 29897/60. Classes 7(2) and 7(6) The working pistons 3 of an engine are connected to primary pistons 5 which actuate secondary pistons 9 through hydraulic links 7, the secondary pistons actuating a swash plate 13 drive gear through connecting rods 10. The pistons 3 are arranged around the swash plate shaft 53 which may form the output shaft but which preferably drives the engine accessories, such as the fuel injection pump, and is connected through gears 54, 52, to the output shaft 55. Synchronization of the pistons 5, 9, is maintained by a valve 30 sliding in a bush 35 in an extension of the piston 5 and connected through a lever 33 to an extension of the piston 9, so as to move with the piston 5. When synchronized, the valve 30 maintains a port 42 closed so that no fluid enters or leaves the pressurized fluid space 6. If piston 5 moves nearer to valve 30 on its working stroke, due for example to leakage of hydraulic fluid, port 42 opens and make-up fluid from supply passage 38 flows through port 42 into the space 6. Similarly if the distance between piston 5 and valve 30 increases, excess fluid escapes through port 42 and the escape passage 47 in valve 30. A pressure relief valve 49 is provided in the passage 7 and an extension 50 thereof blocks the hydraulic fluid supply passage 38 when valve 49 is open. The fuel supply to the appropriate cylinder may also be cut off if valve 49 opens. The swash plate surfaces 19, 20, and the connecting rod ends are lubricated through passages 16, 17, 18.
