Abstract

945,165. Fluid-pressure servomotor systems. BORG-WARNER CORPORATION. March 14, 1960 [ March 26, 1959], No. 8911/60. Heading G3P. [ Also in Division F1] The control rod 25, Fig. 1, of a fuel injection pump is controlled by intake manifold suction acting through pipe 62 on a diaphragm 83, Fig. 2, the suction being modified at low temperatures by an air bleed 65 to the suction chamber 83 controlled by temperature responsive means 13. The air bleed valve 177, Fig. 4, is controlled by the choke valve thermostat 171 which raises the valve 177 off its seat 183 at low temperatures to open an air bleed passage 186 to the passage 65 leading to the suction responsive device 83, thereby reducing the suction and increasing the fuel supply. The intake manifold suction also acts upon a piston 178 attached to the valve 177 to reduce the air bleed at high load. The diaphragm 83 is connected to cam 80 which operates the pump control rod 25 through a follower 98. The cam 80 is pivoted at 93 on an adjustable stop lever 104 and at 94 on a lever 108 adjusted by a cam rod 110 controlled by a barometric capsule 121. The capsule 121 operates rod 110 through a servomotor comprising a pair of opposed diaphragms 122, 123, subjected to suction through orifice 71. The capsule 121 controls through a lever 130 a slide valve 152 which admits air to one or other chamber 140a, 141a, to reduce the suction on one diaphragm and hence cause axial movement of the rod 110 to adjust the fuel supply through the lever 108. The capsule 121 is carried by a follow up lever 127 which returns the valve 152 to its inoperative position after an adjustment. The injection pump 10 is fed through a pipe 20, part of the supply flowing to a pipe 27 connected to a cold start enriching device 14 operated by a solenoid 153 in the starting motor circuit. The solenoid 14 opens valve 54 to allow fuel to flow from pipe 56 to spray orifices 58 in the intake pipe. The flow to the device 14 may be controlled by a valve 47 operated by a thermostat 44. The intake pipe includes a pair of throttles 163, 164, with the throttle levers 201, 203, interconnected through a lost motion spring 209 and links 202,211. A fast idling stop 204 is controlled from the choke valve lever 205 and a normally open switch 230 in the circuit of the extra fuel device 14 is closed by a cam 206 when the choke 162 is closed. A second switch 231 is opened by the throttle control rod 207 at full throttle for deflooding.
