ABSTRACT:
A hydraulic fluid supply system for providing pressurized fluid to fluid actuated components on a refuse collection vehicle, generally including a fluid tank, a pump operatively connected to the crankshaft of the refuse vehicle engine for continuous operation and having an inlet communicating with the tank, a diversion valve having an inlet communicating with the outlet of the pump and having an outlet selectively communicating with the tank and the fluid actuated components on the refuse collection vehicle, means for increasing the idle speed of the engine to a predetermined actuation idle speed when the diversion valve outlet is communicating with the fluid actuated components, and means for preventing the engine from exceeding a predetermined override speed when the outlet of the diversion valve is communicating with the fluid actuated components thereby preventing damage to the pump if an operator accidentally depresses the accelerator pedal in the vehicle.
