Title: Improvements in or relating to fuel supply systems for internal combustion engines
IPC: F02M69/44
Filed: 1958-03-31
Abstract: 869,515. Electromagnetic fuel injection systems; starting. BENDIX CORPORATION. March 31, 1958 [May 6, 1957], No. 10299/58. Addition to 858,961. Classes 7(3), 7(5) and 7(6). [Also in Group XXXV] In an electromagnetic fuel injection system wherein the duration of injection is determined by the duration of current flow to the solenoids of the injection valves 14 from a timing device 32, Fig. 1, controlled by variable impedances, the duration of injection is increased at starting and cold running by a temperature responsive device operatively connected to an electromagnetic means energized by the starting motor circuit. The timing device 32 and current distributor 34 are similar to those described in the parent Specification, the output of the device 32 consisting of current pulses which are connected in sequence to the valve operating solenoids 14 by the distributer 34, the duration of the pulses, and hence of injection, being varied by adjustment of impedances by devices 82, 86, 88, 90 and 92 responsive respectively to intake pipe suction, throttle valve position, acceleration, altitude and engine temperature. In addition a starting device 54, Figs. 4 and 5, adjusts a subsidiary impedance to increase the fuel supply at starting and cold running. The device 54 comprises a shaft 56 controlling the impedance 128, Fig. 1, and connected to one end of a bimetallic coil 102 the other end of which is attached to a lever 104 connected to a plunger 108 forming the armature of a solenoid 112 connected to the circuit of starting motor 120. On starting, the solenoid 112 is energized to pull plunger 108 to the right, Fig. 5, which rotates shaft 56 to increase the impedance 128, for example from zero to 130,000 ohms, and thereby increase the fuel-injection period. When the coil 112 is de-energized the plunger 108 returns to its normal position and shaft 56 is returned to a position, determined by coil 102, which reduces the impedance to a small value, e.g. 200 ohms, to produce an increased fuel supply for cold running, the coil 102 gradually reducing the impedance 128 to zero as the engine warms up. The shaft 56 is connected by a link 62, Fig. 4, and a lost-motion connection 74 to a fast idle cam 58 which carries a pin adapted to be contacted by an extension of the throttle lever 48 in the wide-open throttle position to reduce the fuel supply.

Title: Improvements relating to means for controlling motor vehicle clutches
Filed: 1934-04-05
Abstract: 436,374. Controlling variable-speed gearing. NORMANVILLE, E. J. DE, Haydon House, Kingsbury, London, and DE NORMANVILLE TRANSMISSIONS, Ltd., Humber Road, Coventry. April 5, 1934, No. 10313. [Class 80 (ii)] The clutch of a motor vehicle is controlled from the gear lever by a fluid-pressure cylinder and piston so arranged that when the gear lever is in its neutral position, re-engagement of the clutch, when disengaged, is automatically prevented. In the form shown in Fig. 1, the gear lever (not shown), is in its neutral position. On depressing the clutch-pedal d the piston b is drawn to the right in the cylinder a to the position shown, oil being sucked from the reservoir e into the cylinder through a non- return valve f, which prevents re-engagement of the clutch. If the gear lever is moved to an engaged position, a cam k is turned and depresses a rod h, so as to open the valve f and permit re-engagement of the clutch. In order that the clutch may re-engage in any case after a certain time, a leak m is provided in the cylinder a. In the form shown in Fig. 3, the clutch-pedal d is connected through a pin s and slot r to the piston b, which remains in the position shown while a gear is engaged, and is not affected when the clutch is manually disengaged. If the gear lever is now moved to its neutral position, the cam k depresses the rod h, thus lifting the ball valve f from its seat and admitting pressure fluid from an accumulator to the cylinder a, so that the piston b is forced to the right. The clutch is thus held out of engagement until the gear lever is moved to an engaged position, when the cam k permits the rod h to rise, thus allowing the valve f to close and opening the exhaust passage v in the rod h. Engine suction also may be employed to operate the piston b.
