Title: Improved means for regulating the supply of fuel to internal combustion engines
IPC: F02D9/00
Filed: 1943-06-09
Abstract: 582,519. Controlling fuel. ARMSTRONG, G. J., NAYLOR, B., and DUNNING, J. E. P. June 9, 1943, Nos. 13190/44 (divided out of 582,496) and 13191/44. [Class 7 (vi)] In a fuel supply system, the pressure difference across an adjustable fuel metering valve is regulated by a valve the setting of which is determined by the pressure difference across a centrifugal pump driven by the engine and passing fuel from its periphery to its centre, the fuel being directed from the centre of the pump to the intake manifold. An enginedriven positive displacement pump 11 forces fuel along a passage 13 to the periphery of a centrifugal pump 33 on the same shaft as the pump 11 and to a chamber 14 separated by a diaphragm 38 from a chamber 34 open to the centre of the centrifugal pump, the fuel flowing from the chamber 34 along a passage 35, past a valve 36 and along passages 37, 20 to the intake manifold 27 which it enters at super-atmospheric pressure. A regulating valve 15 carried between the diaphragm 38 and a diaphragm 39 opposite sides of which are open to opposite sides of a metering orifice 19 determines the pressure at the inlet side of the orifice 19 in accordance with the pressure differential across the centrifugal pump 33 and the size of the orifice is determined by a valve 24 actuated by capsules 25, 26, the former being exposed to intake manifold pressure and the latter to atmospheric or exhaust back pressure while a further capsule 29 applies a temperature correction in known manner. The valve 36 responds to the pressure difference across the centrifugal pump against the action of a tension spring 45 and never closes completely, slow running being thus provided for. In a modification shown in' Fig. 2, a single diaphragm 70 is exposed at one side directly to the pressure at the centre of the centrifugal pump 33 and at the other side to a chamber 54 having metering orifices 51, 53 opening into a chamber 50 exposed to the pressure at the periphery of the pump as modified by. valves 57, 61 and 65 controlled by capsules 58, 62 corresponding to the capsules 25, 26 of Fig. 1 and a thermo-sensitive element 66 corresponding to the capsule 29, the capsules determining the sizes of the metering orifices. Specification 582,084, [Group XXVI], is referred to.

Title: Improvements in delayed-action electric relay device
IPC: H01H50/88
Filed: 1928-05-09
Abstract: 321,671. Neale, J. May 9, 1928. Controlling consuming devices.- In an electrical intermittent action mechanism the core of a solenoid is actuated periodically to pump fluid into a container through a device which allows of free flow in one direction, and a restricted and/or controlled flow back, the movement of the fluid serving indirectly to control the circuit of the solenoid. In one modification, Fig. 1, the solenoid circuit is controlled by light falling on a light sensitive cell 7, which actuates relay closing the solenoid circuit. The core 1 is drawn downwards into a tube 3, filled with mercury which it pumps through a tube 5 and control device 8, into a container 6 surrounding the cell 7. The cell is obscured, the relay de-energized and the mercury gradually returns through the adjustable bye-pass tube 10 of the control device. The cell 7 ultimately becomes uncovered and the cycle is repeated. The light controlling the cell 7 may be indeterminate in origin or duration or may be a lamp controlled through a relay by a second cell exposed say to daylight, when it is desired for instance to produce intermittent light from a lighthouse during the night. In a second modification light-control is dispensed with and the circuit of the solenoid 2, Fig. 2, is completed through a floating piston 19 in the tube 3, the core 1 of the solenoid bearing an arm 20, and a contact 23 engaged by the arm 20. When the core is fully depressed the arm 20 leaves the contact 23 and breaks the solenoid circuit, the core rising under the influence of spring 21. The solenoid circuit is not remade until the floating piston 19 reaches the core. A piston 12 in the other container is provided with a contact 13 adapted to close circuits 14, 15, 16 in succession, which however are inoperative on the upward stroke, as a common contact 17, 18 on the solenoid core is broken during that period. Specification 303,224, [Class 40 (v), Wireless signalling &c.], is referred to in the second Provisional Specification.
