Abstract
A throttle valve control system for an automobile having an engine, a carburetor mounted on the engine, a throttle valve in the carburetor for controlling the flow of fuel to the engine, an accelerator pedal, and a throttle linkage interconnected between the accelerator pedal and the throttle valve, the throttle linkage including a throttle linkage adjustment means including a piston/cylinder assembly (11) for expanding and shortening the effective length of the throttle linkage. A throttle limiting closure assembly (16) is mounted onto the piston/cylinder assembly (11) and includes a threaded travel rod (39) and a pair of lock nuts (46) for selectively limiting the amount of expansion of the piston rod from the cylinder. A source of compressed gas is provided including a normally open control valve (19) and an gas flow controller (21). The gas flow controller (21) is selectively adjustable to control the rate of gas flow from the control valve to the piston/cylinder assembly in order to control the rate at which the piston retracts into the cylinder and accordingly the rate at which the throttle valve reopens.
