Title:
PRESSURE ADJUSTMENT MECHANISM OF HYDRAULIC CIRCUIT
Document Type and Number:
Japanese Patent JP2017133682
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure adjustment mechanism of a hydraulic circuit, capable of producing pump discharge pressure matched with maximum supply pressure out of supply pressure levels to be supplied from the hydraulic circuit to respective mechanisms in the hydraulic circuit capable of switching level relationship of DN pulley pressure, DR pulley pressure and CR pressure.SOLUTION: A PH regulator section and a pulley regulator section are individually formed on respective valve bodies of a DN pulley regulator valve 1 and a DR pulley regulator valve 2 along axial directions of the valve bodies. Respective valves 1, 2, 3 are connected in series to relief lines L20-L23. Primary lines of the valves 1, 2 for supplying pulley pressure are configured by two systems of supply side primary lines L1, L2 and return side primary lines L27, L28. Check valves 37, 38, 39, 40, 41 for regulating a flow direction of oil are individually formed on the supply side primary lines L0, L1, L2 and return side primary lines L27, L28.SELECTED DRAWING: Figure 1
