BLANDNINGSVENTIL MED RETARDATOR AV AVSTAENGNINGSROERELSE

A mixing valve comprising a valve body (1), a ceramic plate (2) fixed to the regulating part of the body, the plate having through inlets (7) for hot and cold water, and a through discharge outlet (8) for mixed water, and a mobile ceramic plate (3) having an opening cooperating with the openings in the solid plate (2) for regulation of cold and hot water flows. The mobile plate (3) forms per se or together with a plastic piece (4) a water flow space (11), and a spindle (5) is fitted to the mobile plate (3) which spindle is rotatingly articulated on a limiter (9). In order to avoid a pressure shock in the pipework caused by a rapid closing motion of the cock a means for slowing down the closing action is formed in the spindle (5) at the limiter (9) and separated from the flow space (11). The means for slowing down (10) may comprise a piston placed in a cylindrical through opening of the spindle (5), the piston ends being supported by a curved support surface formed on the inner surface of the limiter (9).
