Oil Pump Of Engine

Smooth operation, low noise. The number of rotor teeth inside and outside the cycloidal rotor pump is only one tooth, when they do relative movement, the sliding speed of the tooth surface is small, and the mesh point is constantly moving along the tooth profile of the internal and external rotor, so the two rotor tooth surfaces wear each other less. Because the envelope Angle of the oil suction cavity and the oil discharge cavity is large, close to 145°, the oil suction and oil discharge time are relatively sufficient, therefore, the oil flow is relatively stable, the movement is relatively stable, and the noise is significantly lower than the gear pump.
