Abstract
Provided is an electronic oil pump which may circulate oil by driving an electric motor, and more particularly, an electronic oil pump which may vary a cross-sectional area of a pumping passage based on an oil viscosity, and include a cooling passage for cooling a motor.
Claims7
An electronic oil pump comprising:
- a lower case having one side where the suction passage and discharge passage of a fluid are formed and the other side where a gerotor seating part is formed;
- an upper case having one side open, having a cooling space formed therein, and having a lower case coupled to an open surface of the one side;
- a gerotor installed on the seating part, and including an internal rotor and an external rotor engaged with each other to be eccentrically rotated for its one side to communicate with the suction passage and the other side to communicate with the cooling space;
- an electric motor installed in the cooling space, and including a shaft for transmitting a rotational force to the gerotor;
- and
- a flexible seal sealing the other side of the gerotor, and opened by an internal pressure of the gerotor to supply the fluid pumped by the gerotor to the cooling space,
- wherein the cooling space communicates with the discharge passage for the fluid exchanging heat with the electric motor to be discharged through the discharge passage.
