Embodiment Construction

[0037] The thermostat mixing valve chosen as the exemplary embodiment has a top part 1, which is equipped on the end side with a rotatable and radially guided stem 2, which corresponds to a threaded sleeve 3, which is threaded The ring 4 is seated axially displaceably in the end piece 1 . The threaded sleeve 3 is coupled with a cone 5 guided axially on the end piece 1 . At its end facing away from the core rod 2 , the top piece 1 is threadedly connected with the threading sleeve 6 , and the sliding block 7 is movably arranged in the threading sleeve, and the sliding block is connected with the thermocouple 8 . At its end opposite the mandrel 2 , the bottom end piece 9 is screwed into the bushing 6 .

[0038] The end piece 1 is formed as a symmetrical hollow body, the two end faces of which are open. In the region of the mandrel 2 , the end piece 1 is provided with a retracted edge 11 , on which the mandrel 2 is supported axially and guided radially. A stepped hollow cylindr...

Abstract

The invention relates to a thermostat mixing valve for sanitary installations, with an axially displaceable top piece incorporating a cone by means of a rotatably mounted stem and a bushing with windows for hot and cold water entry, through A spring-loaded slider can be moved axially in the penetration sleeve, the slider is connected to a thermocouple with an adjusting piston, wherein the entry of hot and cold water through the window can be adjusted according to the movement of the slider, wherein the cone The body (5) comprises a bushing (51) which is closed by the bottom on its underside facing away from the mandrel (2) and in which a conical piston (53) is axially displaceable, The conical piston is preloaded towards the bottom by a spring (54). In the bottom there is a connecting channel axially aligned with the conical piston (53), which is simultaneously axially aligned with the regulating piston (81) of the thermocouple, and the conical piston (53) and / or thermocouple The adjusting piston (81) of the couple (8) can move into this connecting channel, and on the high position (hot water position) of the slider (7), the adjusting piston (81) abuts against the conical piston (53) and the bottom is in contact with the slider The block (7) is spaced, while in the low position (cold water position) of the slide (7) the adjusting piston (81) is spaced from the conical piston (53) and the bottom abuts against the slide (7).

Description

technical field [0001] The invention relates to a thermostat mixing valve for sanitary installations, having a top piece axially displaceable by means of a rotatably mounted mandrel with a cone inside and a bushing with windows for hot and cold water entry, by A spring-loaded slide, movable axially within the bushing, is connected to a thermocouple with an adjusting piston, where the entry of hot and cold water through the window can be regulated according to the movement of the slide. Background technique [0002] Thermostatic mixing valves of the type concerned here are used in thermostatically adjustable shower and / or bath mixing installations as well as in bidet and washstand installations. In these devices, the water volume can be adjusted by the user on the one hand, and the desired water temperature can be adjusted on the other hand. The device has a cold water inlet and a hot water inlet. The two water inlets lead into a water mixing chamber, which is connected wit...
