Abstract

Improvements in the devices for regulating the temperature of a medium, such as liquid, steam or gas, by means of a thermostat without auxiliary force and a valve, characterized by a regulating installation of due value, in which a single sliding piston is found when adjusting the due value, but immobile when an excess temperature is manifested, a pressure accumulator in communication with the thermostat's hydraulic system, filled with a gaseous medium, in which a membrane is movably arranged, in order to ensure the liquid system of the thermostat before overpressure, the increase in the volume of the probe liquid in the temperature probe, when a temperature higher than the adjusted value is manifested, is received by the pressure accumulator, as a result of the variation in the position of the membrane, and when it yields excess temperature in the temperature probe the filling liquid received by the pressure accumulator, without modification Plunger position on the due value adjustment system happens again.
