Abstract

1,002,276. Regulating. ROBERT BOSCH G.m.b.H. June 29, 1964 [June 29, 1963], No. 26761/64. Heading F1B. [Also in Division F2] In a vehicle transmission including an hydrostatic gear (see Division F2), the gear and engine fuel pump are conjointly controlled by regulators responsive to the gear output and engine speed respectively. In the arrangement shown an internal combustion engine 1 is coupled by a shaft 12 to an hydrostatic gear unit 4, 5 of the swashplate type, the pump output being controlled by a servo unit 6. The gear regulator 7 includes a control valve 18, the loading spring 24 of which influenced by the accelerator pedal 15 and a centrifugal governor 28 connected to the motor output shaft 30. The engine fuel pump 2 is of the electromagnetic type, the stroke of the plunger 93 being controlled by a piston 95 in a cylinder 94 connected by a line 97 to the engine regulator unit 8, the valve 69 of which is controlled by a rod 73 and piston 76 operated by main and auxiliary springs 75, 81 and a centrifugal governor 84 driven by the engine output shaft 12. A mechanical arrangement for operating the fuel pump is also described, Fig. 2 (not shown). Upon moving the pedal 15 the pressure in the gear regulator 7 rises and this is transmitted via engine regulator 8 to pump control cylinder 95 to move pump plunger 93 to the left. At the same time servo piston 41 operates to tilt the pump swash plate 53 to start the gear unit 4, 5. If the speed reaches an excessive value governor 28 operates to reduce the load on valve 18 and the pressure in line 97 and cylinder 94, to reduce the output from fuel pump 2, the setting of the gear unit remaining unaltered. Should the speed fall the load on valve 18 is increased and the pressure in the fuel pump cylinder 94 also rises to increase the pump output.
