Priority hydraulic flow diverter control assembly

摘要

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 enables the system to operate in the most efficient manner with respect to pressure drop and flow loss. The 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. When back pressure is high, the pressure sequence valve diverts hydraulic fluid flow from the refuse cart lifter circuit into the system tank. This allows all hydraulic operated equipment to operate that their intended speed at high and low system back pressures. 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.
