Abstract
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.
high efficiency by equalized flow rate,
-
2.
reduced sliding which yields less frictional (torque) loss, and
-
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.
