Abstract
An idle speed control for an internal combustion engine has a crankcase adapted to be connected to a fuel metering device used to selectively deliver fuel to the engine in response to pressurized air pulses generated in the engine. The idle speed control includes a vessel having a pressure actuated member movably mounted therein to define a first chamber and a second chamber. The second chamber is provided with a biasing device acting on one side of the pressure actuated member and the first chamber admits the pressurized air pulses acting on an opposite side of the pressure actuated member and controllably leaking a portion of the pulses therefrom. The idle speed is controlled by a leak-down rate of pressurized air pulses released from the second chamber.
