ABSTRACT:
A valve is positioned by a control diaphragm which senses manifold pressure in an automotive engine and by an opposing biasing spring to create a control pressure, and a servo diaphragm positions the throttle in response to variations in the control pressure to thereby maintain the manifold pressure at a value determined by the spring bias. The vehicle operator positions the accelerator pedal to vary the spring bias and thus determine the value at which the manifold pressure is maintained.
