OIL PUMP CONSTRUCTION

BHE011101008T06

• A trochoid type oil pump has been adopted.

• A two-rotor type oil pump has been adopted for improved oil discharging ability and downsizing. It is also beneficial for reducing discharging pulsation.

• An efficient, compact 4-lobe epitrochoid and 5-flank inner envelope type gear has been adopted for the oil pump.

• The oil pump consists of oil pump body, shaft, front outer rotor, front inner rotor, middle plate, rear inner rotor, and rear outer rotor.
