Patent GB-793616-A (GB)
Title: Improved control system for variable-speed power transmission
IPC: F16H59/20
Filed: 1955-10-20
Abstract: 793,616. Change-speed control. GENERAL MOTORS CORPORATION. Oct. 20, 1955 [Nov. 8, 1954], No. 12711/57. Divided out of 793,615. Drawings to Specification. Class 80(2). The subject-matter is the same as that of Specification 793,615, but the claims are directed to the speed- and throttle-variable shift-valve control system and in particular to three control valves (see abridgment of Specification 793,615) comprising a low control valve 205, rear clutch exhaust valve 210 and cut-off valve 220, each of which is moved at a predetermined value of one of the variable pressures to control the flow of a variable pressure. Thus, in the case of the low control valve 205, that valve, which in L setting of the manual valve cuts off governor pressure from the front shift valve to maintain reduced drive, is raised when governor pressure exceeds a predetermined value to restore governor pressure to the shift-valve for safety upshift. In the case of the rear clutch exhaust valve 210, that valve is opened when pressure in the rear clutch servo chamber exceeds a predetermined value during low-speed downshift due to thrust on the corresponding brake piston from the pressure-chamber 92a (pressurized below 10 m.p.h.). This permits rapid exhaust of the servo clutch pressure. The cut-off valve 220 is opened when governor pressure falls below a value corresponding to 35 m.p.h. vehicle speed to permit kickdown pressure to reach and act on the rear shift valve. Specifications 522,881, 728,461, 731,653, 742,552 and 773,472 are referred to.

Patent GB-639260-A (GB)
Title: Improvements relating to fuel systems for gas-turbine engines
Inventor: DAVIES KENNETH ROY
IPC: F02C7/22
Filed: 1947-05-12
Abstract: 639,260. Fluid-pressure servomotor-control systems. ROLLS-ROYCE, Ltd. May 12, 1947, No. 12820. [Class 135] [Also in Group XXVI] In a fuel system for a gas-turbine engine in which a constant volume engine-driven pump 16 passes liquid through restricting means 18. variable by a speed-selecting device 20 and in which means, e.g. a piston 13, responsive to the pressure drop across the restriction 18, is operative to vary the fuel delivery to the engine, means, e.g. a capsule 37, responsive to changes in atmospheric or ambient pressure is arranged in association with the restriction 18 to vary the pressure drop across the latter, and hence to vary the fuel supply, in accordance with altitude. As shown, movement of piston 13 varies the swash-plate of a multi-plunger pump 10 supplying fuel to injection devices 12, and the capsule 37 varies a restriction 39 in parallel with the restriction 18. To prevent overfuelling by pump 10, a diaphragm valve 25 is inserted in the line between pump 16 and the inlet side of restriction 18, and the valve is loaded by a spring and, through passage 28, by the pressure on the downstream side of the restriction. This ensures that the valve will not open until a selected minimum pressure drop occurs across the restriction and, as this pressure drop is applied across piston 13, it will prevent the latter from moving too far to the left, i.e. in the increase fuel direction. Similarly, a diaphragm valve 29 byepassing restriction 18, and acting like a pressure-relief valve, prevents underfuelling. Valves 25, 29 are further loaded by an evacuated capsule 34 so that the maximum and minimum limits of fuel delivery are varied in accordance with changes in altitude. The effect of capsule 37 can be modified to give different results at varying engine speeds by providing a further restriction in series with restriction 39, and varying the former restriction by means of a piston subject to the differential pressure across a fixed throttle inserted in the fuel line between pump 10 and the injection devices 12. In a modification of this last system, the fixed throttle is inserted in the delivery line of pump 16 and the piston moves along a floating lever to which the capsule and its associated plunger are separately attached. Specifications 639,261 and 639,262 are referred to.
