摘要
An engine throttle is controllably positioned by an electric motor which is coupled to the throttle through engaged, first and second, variable-radius scroll gears. The motor works against the force of a throttle return spring, and this force increases as the throttle is driven away from a fail-safe position. By choosing the variation of the ratio of the scroll gear radii to match the variation of the force developed by the spring with throttle position, a constant driving torque produced by the motor will overcome the increasing torque produced by the spring.
