Abstract:
A throttle stop apparatus for selectively regulating the power of an internal combustion engine of the kind having intake valves and an air-fuel metering device, said throttle stop apparatus comprising,a body that permits the throttle stop apparatus to be mounted in the flow path between the air-fuel metering device and the intake valves of the engine,throttle stop means within the body and moveable between a full open position and at least one flow restricting position for selectively regulating the power of the engine by controlling the flow from the air-fuel metering device to the intake valves,said throttle stop means being constructed to create substantially no restriction to said flow in said full open position at wide open throttle conditions of the engine andwherein the throttle stop means comprise at least a first plate and a second plate, each plate having an opening with a configuration and dimensions sufficient to create substantially no restriction to said flow in said full open position of the throttle stop means, and including actuating means for moving at least one plate relative to another to provide full alignment of said openings in said full open position at wide open throttle conditions of the engine and to provide at least partial restriction to said flow at said flow restricting position of the throttle stop means.
