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 fittings, comprising a head piece, in which a cone is arranged in an axially movable manner by means of a rotatably positioned spindle,and a through-passage with windows for the supply of hot and cold water, in which a carriage that is pre-tensioned by a spring can be axially moved, said carriage being connected to a thermoelement comprising a control piston. The supply of hot and cold water through the windows can be regulated according to the movement of the carriage, and the cone (5) comprises a bushing (51) that is closed onthe lower side thereof facing away from the spindle (2) by means of a bottom and in which a conical piston (53) can be axially moved, said piston being pre-tensioned towards the bottom by means of a spring (54). A coupling channel axially aligned with the conical piston (53) is arranged in the bottom, said coupling channel also being axially aligned with the control piston (81) of the thermoelement, and the conical piston (53) and / or the control piston (81) of the thermoelement (8) can be moved into said channel. In an upper position of the carriage (7) (hot water position), the control piston(81) is applied to the conical piston (53) and the bottom is at a distance from the carriage (7), and in a lower position of the carriage (7) (cold water position), the control piston (81) is at a distance from the conical piston (53) and the bottom is supported on the carriage (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...
