ABSTRACT:
A priority hydraulic flow diverter control assembly for a refuse collection vehicle hydraulic system provides proper and efficient flow in an auxiliary hydraulic circuit regardless of the primary flow so that refuse cart lifters and the refuse cart operate safely and efficiently. A pressure sequence valve diverts hydraulic fluid flow from the refuse cart lifter circuit into the downstream main hydraulic system when downstream back pressure is low, and into the system tank when back pressure is high. This allows all hydraulic operated equipment to operate at their intended speed whether at high or low system back pressure.A differential pressure sensing valve and flow regulating valves provide a precision flow. Harmful and undesirable vibrations and noise associated with pulses in hydraulic system pressure are reduced using a control orifice located in the valve body. A relief valve ensures that the diverter control assembly is compatible with other manufacturer's products.
