What is the rotor-type oil pump, which is how it works?
Rotor type oil pump oil pump is in one, compared to gear oil pump, its compact structure, small size. The rotor of the composition of organic oil pump oil pump housing, inside and outside the oil pump rotor and pump cover. Wherein the inner rotor by a key or a pin, fixed to the rotor shaft in the pump, and then the oil pump from the crank gear, driven by the rotor shaft directly or indirectly drive-rotor axis.
Wherein the inner rotor and the outer rotor has an eccentric distance of the center, the inner rotor will drive up the outer rotor, are disposed along the same direction with the rotation. General type rotor pump, its convex inner rotor teeth is about four, or even more. Concave outer rotor teeth than the convex inner rotor teeth, to be more on one. In this way, with the outer rotor in the same direction can not be rotated simultaneously.
This design of rotor teeth, causes the rotor to any angle, the external teeth of the rotor can always come into contact with each other to collide. Inner rotor will form four studios, and because the rotor is constantly turning, so this studio volume are constantly changing, when the studio when the volume becomes large, it will create a vacuum, which when the suction oil, and becomes small when the studio, hydraulic natural increase, and the oil was fed to the oil passage to the parts it should go. So come and go in rotation, so the oil is sucked in constantly and output.
