Abstract

A thermostatic valve contains a hollow cylindrical valve element, each of whose two ends form an inlet port for hot or cold water. The mixed water formed by mixing hot and cold water strikes a temperature sensor which, as a function of the temperature, displaces the valve element to a greater or lesser extent.Within the valve element is located a mixing device, which divides the inflowing hot water into several flows, namely two radially directed flows and an axial flow flowing round the end of a sleeve. The radial parts of the hot water flow are encountered by an axial cold water flow. This leads to a particularly intimate mixing of hot and cold water before the temperature sensor is reached.
