| 摘要 |
A rotor-type variable oil pump, in which a gap is provided between a plunger (140) and a cylinder (130) to easily operate the plunger (140) using an oil pressure output from the oil pump, enabling more rapid supply of a required amount of oil using an oil pressure varied according to variation in an engine RPM. The plunger (140) is perpendicularly operated with respect to a flow direction of the working fluid, such that the plunger (140) can be operated in a direction in which a pressure of the working fluid is applied to rapidly and precisely operate the oil pump. |
