Fluid Pump: Description and Operation

OUTLINE




- The light-weight, compact, and quiet trochoid gear type oil pump reduces pump driving torque
- The direct drive type oil pump is placed behind the torque converter

STRUCTURE




- The outer rotor and the inner rotor are installed in the oil pump housing. The inner rotor in the oil pump housing is driven by the torque converter.

OPERATION




- When the inner rotor in the oil pump rotates, the ATF is drawn to the oil pump. The discharge amount is proportional to the rotating speed of the torque converter.
