A heating radiator valve (1) has an insertion (8) which may be secured to a connection piece (6) and which contains a valve seat (15) with which a thermostatically actuated closing body (14) cooperates. The heating medium is conveyed to the valve seat (15) through a hollow extension (18) of the insertion (8) or the connection fittings (2). The extension (18) extends along the same axis as the insertion (8). After flowing through the valve seat (15), the heating medium flows into a chamber (23), then in the axial direction of the insertion (8) into an annular space (25) located between the connection piece (6) and the extension (18), through a return piping (21) constituted of axial channels (22) shaped in the material of the insertion (8). The valve seat (15), the closing body (14) and the chamber (23) are rotationally symmetrical with respect to the axis of the insertion (8); when the valve is open, they delimit a ring-shaped discharge slot for the heating medium. A construction which can be universally used, which is not prone to obstruction and which favours the flow of the heating medium is thus achieved. |
