High Efficiency Oil Pump Rotor With New Tooth Profile 2004-01-0498

We have developed high efficiency oil pump rotors with a new tooth profile. This profile design is designated intelligent profile rotor (IPR). Its features are:
  1. 1.
    high efficiency by equalized flow rate,
  2. 2.
    reduced sliding which yields less frictional (torque) loss, and
  3. 3.
    lower noise by decreasing the working clearance to 1/3 or less of standard design.
We have also improved the dimensional accuracy of sintered rotors, reducing or eliminating machining.
