Away from realization lubricating oil pump becomes discharge capacity, and operation of oil pump is in low-pressure stage；When high engine speeds work, electronic control unit controls hydraulic valve, opens
Open the oil inlet passage between engine main oil gallery and over spring oil pocket, the oil inlet simultaneously of short round spring oil pocket, over spring oil pocket, short round spring
Oil pocket side adjusts ring compression active area and is greater than over spring oil pocket side adjusting ring compression active area；Adjust ring compression reseting spring
It is rotated around pin shaft hinged place, adjusts rotor and drive shaft and adjusting the eccentricity in ring, realize that lubricating oil pump becomes discharge capacity, operation of oil pump
In hiigh pressure stage.
A kind of scheme of optimization is that the utility model further includes hydraulic valve and oil sump connecting pipeline；Low engine speed work
When making, electronic control unit controls hydraulic valve, the oil inlet passage between stopping engine main oil gallery and over spring oil pocket；It is automatically controlled simultaneously
Unit controls hydraulic valve, opens the oil discharge passage between over spring oil pocket and connection oil sump, discharges over spring oil pocket pressure, adjusts
Ring compression reseting spring is rotated around pin shaft hinged place, is adjusted rotor and drive shaft and is being adjusted the eccentricity in ring, realizes lubricating oil pump
Become discharge capacity, operation of oil pump is in low-pressure stage.
The utility model has the following positive effects: when due to high engine speeds work, over spring oil pocket relative proximity spring oil
Chamber oil inlet is that negative role is offset to adjusting ring is rotated clockwise, and spring design rigidity is small；And compared with original technology, over
Spring oil pocket, short round spring oil pocket is small, and changeable flow adjustment is sensitiveer.
