ABSTRACT:
A throttle positioning device for prevent rapid closure of the throttle valve of an internal combustion engine under extreme decel conditions. The throttle control device includes a vacuum motor that is responsive to the pressure in the induction system at a point just slightly upstream of the throttle valve of the engine so that vacuum will be exerted on the vacuum motor when the throttle valve is substantially opened from its idle position and atmospheric pressure will be exerted when the throttle valve is closed toward its idle position. Various arrangements are provided for adjusting the rate of air flow between the vacuum motor and the intake passage in different directions.
