A multi-port valve (2) has a valve body (4), a directional component (6), and an elastomeric seal. The valve body is formed as an annular cylinder with plurality of ports (12a-12d) extending from an outer circumferential surface and in inner circumferential surface further defines a cavity. The directional component is positioned in the cavity and defines a channel in an outer circumferential wall that provides fluid communication between combinations of two or more of the plurality of ports depending upon an angular orientation of the directional within the cavity. The elastomeric seal is positioned between the directional component and the inner circumferential surface of the valve body and defines a plurality of apertures aligned with the ports to provide fluid communication between the channel and the plurality of ports. The elastomeric seal provides a fluid seal and a low-friction interface between the directional component and the inner circumferential surface of the valve body. |
