ABSTRACT:
The present invention is directed to a throttle control device to be used in combination with an engine having a throttle and a pump driven by the engine. The automatic control device has a housing defining a chamber having a first opening adapted to receive a fluid containing conduit in communication with the pump. A piston is slideably mounted in the chamber and has a first end acted on by a fluid contained in the conduit. A spring surrounds a portion of the piston within the chamber and biases the piston towards the first opening and, therefore, the fluid. A second end of the piston extends through a second opening in the chamber and controls the throttle. A first adjustable stop in the chamber limits travel of the piston and a second adjustable stop controls the compression of the spring.
