ABSTRACT:
An apparatus for controlling or regulating the through-flow or passage of at least one liquid, particularly for temperature regulation or control, contains at least one valve with an electrical valve drive, which is controlled by an electronic control unit. The control unit makes available the signals necessary for operating the valve drive. The power supply for the control unit and the valve drive is provided by a thermocouple, whose one side is exposed to the temperature of the liquid to be regulated and whose other side is exposed to a temperature differing therefrom. The apparatus preferably contains a storage battery.
