Title: Improved throttle mechanism for motor vehicles
IPC: F01L13/00
Filed: 1956-11-29
Abstract: 809,173. Controlling vehicles. GENERAL MOTORS CORPORATION. Nov. 29, 1956 [Dec. 5, 1955], No. 36504/56. Class 79(5) [Also in Group XXVII] A motor vehicle throttle control mechanism comprises a spring biased throttle linkage connected to a throttle control member through a lost motion connection, so that movement of the control member to the open position positively moves the linkage and movement of the member to the close position permits linkage to move under the action of its spring bias to the open position, and a device effective when the brake is applied to close the throttle,. relative movement occurring in the lost motion connection, the device comprising a pair of mutually contractable lever arms, one forming part of the throttle linkage and the other being connected to the brake actuator, and which are arranged so that throttle movement towards the closed position is at a greater rate during initial application of the brake actuator. A bell crank throttle lever 6, on engine 4, is biased to the throttle open position by a spring 14 and connected by rod 10 to the free end of arm 20 of a double armed lever 22 mounted in a casing 26, Fig. 4, fixed to a plate 27 on a body panel 28, the other arm 30 being connected by a Bowden cable 38, 40 to a manual control lever 46 on a pivot 48, a pin 34, Fig. 5, at the end of cable 38 moves in a slot 32 in lever 30 under control of lever 46. For opening the throttle, lever 46 is moved anti-clockwise to move pin 34 along slot 32 allowing the spring 14 to pull lever 10 to open the throttle, the end 54 of the slot following the pin 34. To close the throttle the lever 46 is moved clockwise to force pin 34 against end 54 to swing arms 30 and 20 to shift rod 10 to close the throttle. To effect throttle closing during braking. the brake pedal 56 has a defendant arm 58 connected to a lever 76, Fig. 4 by a Bowden cable 62, 64 held in brackets 68 and 70. Cable 62 is attached to lever 76 by a ball and socket joint and lever 76 is connected to a lever 82, through a casing 80 fixed to plate 27, which carries two cam rollers 84, 86, Fig. 5. Depression of pedal 56 causes arm 82 to swing so that roller 84 rocks arm 20 forwards to close the throttle to a fast-idling condition. When both rollers 84 and 86 contact the arm 20 further depression of the pedal 56 will not further close the throttle. The arm 82 returns to its normal position when the brake is released permitting the throttle to open to the previous setting of the manual lever.

Title: Gas Turbine Fuel Control System
IPC: F02C9/32
Filed: 1967-08-18
Abstract: 1,171, 371. Gas turbine engine fuel systems. FORD MOTOR CO. Ltd. Aug.18, 1967 [Oct. 3, 1966], No. 38198/67. Heading F1G. A gas turbine engine fuel system comprises a fuel flow control means variably restricting the discharge line from the fuel pump, a predetermined pressure differential between portions of the discharge line upstream and downstream of the flow control means being maintained by a by-pass means connected between the downstream portion and the pump inlet line and acted on by the pressure differential, and additional force means acting on the by-pass means in a by-pass opening direction, the additional force means being acted upon in one direction by compressor discharge fluid in opposition to spring means and fluid at the pressure of the inlet line. A fuel system for a gas turbine engine installed in a motor vehicle comprises an enginedriven fuel pump 12 delivering fuel via a manual throttle valve 24 and a fixed restrictor 98. The pressure differential across the throttle valve 24 is maintained constant for each position of the valve by means of a by-pass valve 56 connected to return fuel from a point 36 downstream of the throttle valve to the pump inlet 18 and controlled by a diaphragm 46 exposed to the pressure differential. Similarly, the pressure differential across the restrictor 98 is maintained constant by means of a by-pass valve 124 connected in parallel with the by-pass valve 56 and controlled by a diaphragm 110 exposed to this pressure differential. Both by-pass valves 56, 124 are also controlled in accordance with the discharge pressure of the engine compressor (which varies with engine speed and ambient temperature). For this purpose, a further diaphragm 74 or 138 acts on the respective by-pass valve, the diaphragm being subjected on its lower surface to the fuel pump inlet pressure and on its upper surface to a pressure desired from the compressor discharge pressure via a pressure potentiometer 82, 82 or 144, 144. The compressor discharge pressure tends to open the by-pass valve 56 and to close the by-pass valve 124. A normally open valve 174 is connected in parallel with the restrictor 98. When the temperature at the outlet from the regenerator to the combustion equipment exceeds a desired level, a temperature-sensing probe 160 moves the valve 174 towards the closed position to reduce the fuel flow. During acceleration, the by-pass valve 56 is closed (unless excessive compressor discharge pressure opens it) until the engine speed set by the position of the throttle valve 24 is reached, when the by-pass valve opens to stabilize the fuel flow at the constant rate determined by the position of the throttle valve. Similarly, the by-pass valve 124 is closed during acceleration until the increased pressure differential across the restrictor 98 opens the by-pass valve against the force exerted by the increased compressor discharge pressure to cut down the fuel flow so as to hold the engine at the speed reached.
