The regulator is provided with a by-pass path for the connection of the outlet and inlet ports of the compressor, a valve for opening and closing the valve and a temperature controller for controlling the valve according to the temperature of the liquid. The by-pass path is closed when the liquid temperature is higher than a preset value and it is closed when the liquid temperature is lower than the value.
