Take distributing valve subassembly of cooling and lubrication oil circuit

The utility model provides a take distributing valve subassembly of cooling and lubrication oil circuit has designed the cooling and lubrication passageway in subassembly axial direction hole department, include the distributing valve oil extraction oil circuit of oil feed oil circuit, the oil groove excessively on the thimble seat and the distributing valve eccentric orfice bottom of hole bottom portion with one heart. The utility model discloses can let the low temperature fuel in the high pressure chest rely on the oil feed oil circuit to get into the axial direction hole, arrive the working face of thimble seat and thimble, lubricated work face and lowering the temperature. Because the autogyration of valve, the fuel after the working face heaies up can be followed the oil extraction oil circuit and thrown away, and it is vice that the friction of valve subassembly is flowed through from the high pressure chest to the fuel, reachs the low pressure oil pocket after taking away the heat, is showing the temp
