Abstract
PURPOSE: To reduce the depressing load of an accelerator pedal throughout a full range of its using condition, by providing an oil chamber, having a land difference, to a downshift plug in a throttle valve and feeding cut back pressure to said oil chamber.
CONSTITUTION: If cut back pressure, adjusted through a cut back valve 250 by governor pressure and throttle pressure changed in accordance with car speed, is applied to an oil chamber 248 in a throttle valve 240, force (accelerator pedal depressing load), moving to hold a downshift plug 242 to an optional position, is reduced by the cut back pressure acting upon the downshift plug 242 in the oil chamber 248. Further this amount of reduction is increased in accordance with a depressing state of the accelerator pedal, then a depressing load of the accelerator pedal can be decreased fully throughout an accelerator opening.
