摘要：An oil pump emits less noi by properly forming the profiles of teeth of an inner rotor and an outer rotor thereof which engage each other, whereby decreasing
sliding resistance and rattle between the tooth surfaces of the rotors. The rotors (10, 20)of the oil pump are formed in such a manner that the inner rotor (10) having "n" teeth is
