The multi-port valve comprising an inlet and at least two outlets according to the present invention is based on a supporting body (1) with a through hole (2) defining along its circumference in the supporting body (1) a guide way (3) of circular form in plan and in front cross section with a vaulted arch-shaped surface (4), whereby in such created space of the supporting body (1), there is rotatably mounted a working head (5). Said working head (5) axis of rotation (6) passes through the center of the through hole (2) perpendicularly to the plane of the supporting body (1). In the working head (5) axis of rotation (6), said working head (5) is provided with an axial inlet channel (7) being followed up with a radial channel (8) passing through a length-adjustable element (9) of the working head (5) up to the guide way (3) vaulted arch-shaped surface (4), against which said working head (5) length-adjustable element (9) bears with prestress through the mediation of a shaped sealing element (10) simultaneously with the fixed spacing elements (11) of the working head (5). The vaulted arch-shaped surface (4) of the guide way (3) consists of a sliding seal of an abrasion resistant plastic, preferably polytetrafluoroethylene, the supporting body (1) along with the sliding seal is provided with continuous outlet channels (12) distributed along the circumference of the supporting body (1) and having a geometry following up with the radial channel (8) in the length-adjustable element (9) of the working head (5). |
