GEROTOR-TYPE PUMP

摘要

The pump has an inner rotor bounded by an outer peripheral shape (20) which is generated by moving a first circle around a first trochoid. The inner rotor is mounted for rotation about a first axis. The pump also has an outer rotor mounted for rotation about a second axis which is off-set from the first axis. The outer rotor is bounded by an inner peripheral shape (22) which is generated by moving a second circle around a second trochoid.
