Throttle valve controlling apparatus

Abstract

Abstract PURPOSE:To enable to operate a vehicle always with a proper specific fuel consumption, by providing a cylinder mechanism incorporating therein a piston at an intermediate portion between an accelerator pedal and a throttle valve, and controlling charging and discharging of pressure oil to and from cylinders according to the operational conditions of the vehicle. CONSTITUTION:At an intermediate portion of a wire 3 connecting an accelerator pedal 1 and a throttle valve 2 to each other, there is provided a throttle valve controlling mechanism 4 which consists of a first cylinder having therein a piston 7 disposed in a freely slidable manner and a second cylinder 13 incorporating therein the first cylinder 5. In the state that servo valves 25, 26 are 1ocated at the positions shown in the drawing, the acclerator pedal 1 and the throttle valve 2 are interlocked as it is. At the time of changing the reduction gear ratio, the servo valves 25, 26 are moved to the left in the drawing by an arithmetic means which detects various operational conditions of a vehicle, whereby the piston 7 is moved rightward with respect to the first cylinder 5 by pressure oil and the engine speed is increased by opening the throttle valve 2 to an angle greater than the depth of depression of the accelerator pedal 1. At the time of rapid acceleration, on the other hand, the specific fuel consumption is lowered by the reverse operation of the mechanism 4.
