Abstract
Provided is a gerotor pump including an inner rotor connected to a driving axis of a motor to transfer rotation force, an outer rotor formed at an outer side of the inner rotor, and a casing receiving the inner and outer rotors therein and provided with an inlet and an outlet, the inner and outer rotors forming several closed chambers while eccentrically rotating, having a predetermined clearance therebetween, to transfer a fluid, wherein a pressure chamber is formed in the casing in a direction in which force acts on the outer rotor by pressure of the fluid to offset the force, such that frictional force between the outer rotor and the casing decreases, thereby making it possible to improve performance and efficiency of the pump.
