Abstract
The idling system reduces the speed of an engine having a speed governor that is used to power an air compressor, a pressure washer, or another load device which outputs pressurized gases or fluids. The idling system includes a pressure or flow switch which is activated in response to a sensed pressure or fluid flow respectively in the load device. When the switch is activated, an electromagnet is energized through a diode rectifier by the engine alternator or other power source. The energizing of the electromagnet creates a magnetic field that attracts a governor lever arm on the engine's mechanical speed governor. Since the lever arm is interconnected with the throttle plate of the engine carburetor, movement of the lever arm rotates the throttle plate to reduce the engine speed to an idle speed.
