The machine oil that slave oil pump body oil outlet flows out enters the engine lubrication system main oil gallery behind filter cleaner.For accurately controlling the force value of engine lubrication system main oil gallery, described oil pump body is provided with the control oil duct and second pressure-limit valve.
Described control oil duct is connected with main oil gallery, and described second pressure-limit valve is arranged in the control oil duct.
Be connected with main oil gallery by controlling oil duct, when the main oil gallery oil pressure was too high, second pressure-limit valve carried out pressure release under pressure, to guarantee that main oil gallery pressure is within zone of reasonableness.
As a further improvement on the present invention, described control oil duct is arranged on the described oil pump body flexibly according to the position of main oil gallery, and the force value setting of described second pressure-limit valve can be adjusted as the case may be.
The invention has the advantages that: the present invention for the pressure of controlling the motor main oil gallery in reasonable range, reduce pressure oil duct behind the pump to the influence of filter cleaner between the lubrication system main oil gallery and module to engine oil pressure, on the oil pump body, directly increase main oil gallery pressure control oil duct, by in the control oil duct second pressure-limit valve being set, the engine oil pressure level that guarantees each friction pair of motor main oil gallery is in reasonable range.The present invention is simple in structure, and it is convenient to use, and can guarantee engine lubrication system main oil gallery pressure in the reasonable scope, effectively prevents the influence of engine oil pressure too high in the main oil gallery to each parts of motor.
