Abstract
Provided is a valve-integrated electrical water pump in which an impeller for circulating a coolant to the outside and a valve for selectively opening and closing a plurality of ports inside an integrated housing to control a circulation of a coolant used in electric vehicles, thereby simplifying the overall structure of the pump and simplifying an internal flow path.
Claims8
A valve-integrated electric water pump comprising:
- a valve installed on an inner lower side of an integrated housing and rotating according to an operation of an actuator to selectively open and close a plurality of in-ports;
- and
- an impeller rotatably installed on an upper side of a stator fixedly installed on an upper side of the valve, in which a rotor protruding at a lower end is disposed to penetrate through the stator, and a discharge flow path and an intake flow path formed in a penetrating manner vertically in a center of the rotor are integrally connected to each other,
- wherein an outlet flow path formed at an upper end of the valve and the intake flow path are connected to allow coolant to flow therethrough.
