Abstract
The invention relates to a thermostatic valve regulating system having a central control unit for operating two or more remotely located valve operating units. The valve operating units are for heat transfer equipment such as radiators. The valve operating units have expansible chamber elements and associated valve operating rods. The central control unit has an adjustable temperature response expansible chamber element -TRECE) with a vapor-liquid filling. The central control unit also has a transmitting expansible chamber element (TECE) which is connected to all of the expansible chamber elements of the valve operating units with capillary tubing. The capillary tubing and the connected expansible chamber elements are filled with a liquid transmitting element. The temperature responsive TRECE is in series relation to TECE and expansion and recession thereof cause an opposite recession or expansion of TECE. The expansion and recession of TECE is transmitted via the transmitting liquid to each of the expansible chamber elements of the remotely located valve operating units. SU
