Beschreibung
Zusammenfassung:	The invention relates to a multi-port valve comprising a valve housing having an axial port and a plurality of circumferential ports, and a valve member having at least two flow channels therethrough. The valve member is movable within the valve housing about an axis to alter a fluid flow through the multi-port valve by changing the position of the at least two flow channels. At least one proportional flow condition is achievable between the plurality of circumferential ports. There is also a sealing arrangement positioned between the valve housing and the valve member, the valve member being movable relative to the sealing arrangement. The sealing arrangement comprises a seal associated with each of the plurality of circumferential ports. In one embodiment of the invention, the seal associated with the third circumferential port and the seal associated with the fourth circumferential port are provided on a single sealing element.
