양토출 베인타입 오일펌프의 유동 특성에 관한 해석적 연구

Oil pump for an automatic transmission is responsible for two functions, high-pressure generation for shifting and oil supply to the low-pressure line for lubrication. Oil pump for an automatic transmission to date, there has been a problem that power loss issues because designed to total flow-rate required at high pressure line. Due to lubricating oil supplied by decompressor lowering the pressure, component is further required and there is problem that power loss issues. vane type oil pump with double discharge, single suction is a structure vane type of rotor by rotation, which at the same time is discharged occurred high pressure and low pressure without a pressure reducing device, it is possible to reduce power consumption. In this study, the basic performance characteristics of the pump, flow characteristics of the discharge port volume change, improve the primary discharge port flow line has been examined using CFD analysis.
