The valve core defines a plurality of flow channels, each extending through a sidewall of the valve core to form two opposite open ends. The valve housing is provided with a guider passage, and the plurality of flow channels include a first flow channel, a second flow channel and a third flow channel. The multi-port valve is operable to be switched between a plurality of work modes in response to the valve core rotating to different positions relative to the valve housing. The first flow channel is connected in series with the second flow channel via the guide passage in response to a first work mode of the plurality of work modes.

摘要： A multi-port valve includes a valve housing and a valve core. The valve housing includes a plurality of ports arranged in a circumferential direction. All the ports are grouped into at least two port groups. Each of the port groups includes a main port and a plurality of sub-ports. The valve core is rotatably mounted to the valve housing and defines at least two flow channels. The multi-port valve has a plurality of work modes in response to the valve core rotated as regard to the valve housing to different positions. In different work modes, each of said at least two flow channels is configured to selectively communicate one of the main ports with one of the sub-ports.
