Three-way valve (1) including two co-axial through flow openings (12, 13) and a valve body (5) co-acting therewith, for optional distribution of the flow through these openings. The valve body comprises two mutually relatively axially movable valve body parts (6, 7), which can also be mutually relatively arrested. These parts are moved between different arresting positions by the valve body being urged by its stem against an abutment surface (the valve seat 14 or 15), at at least one through flow opening (12 or 13). A change in the relative axial positions of the valve body partts (6, 7) changes the total through flow capacity of the valve. The valve can thus achieve a variable constriction of the total flow. |
