Abstract
920,924. Valves. M. CLAUSEN, [trading as DANFOSS VED ING M. CLAUSEN]. Nov. 1, 1961 [Nov. 3, 1960], No. 39149/61. Class 135. [Also in Group XIII] In a thermostatic valve having a fluid-vapour thermal medium in a valve operating element, e.g. bellows connected by capillary tube to a probe, the bellows being in thermal-conducting relationship with a heating or cooling fluid, controlled by the valve, the ratios, respectively, of the volumes of the bellows and probe, which are normally substantially equal, to the volume of thermal medium is arranged so that, depending on the temperature of the valve-controlled fluid, evaporation at the surface of the thermal medium takes place either in the probe or in the bellows. When heating fluid is supplied at 30 and bleeds via 33, 34 over bellows 35, 38 the medium in 35 evaporates and condenses to fill the cold probe 37 but has its surface at a high temperature in 35 so that the vapour pressure fully opens valve 41 against temperaturesetting spring 46. The medium in bellows 38 evaporates and condenses with its surface in probe 40. Evaporation then occurs in accordance with the temperature of probe 40 and the valve 43 co-operates with its seat to control flow of heating medium in accordance with the room temperature detected by probe 40. When cooling fluid flows around the bellows, the medium condenses with its surface in 38 and the low vapour pressure allows setting spring 47 to fully open valve 43. Medium condenses in 35 with its surface in probe 37, valve 41 moves towards its seat and controls cooling fluid flow in accordance with vapour pressure in probe 37 determined by room temperature. The valves may be used separately.
