Abstract
A temperature sensitive negative-pressure control valve is provided with a pressure adjusting means functioning to output a constant negative-pressure which is determined by the biasing force of an adjusting spring, and a temperature sensitive device for varying the biasing force of the adjusting spring, whereby variation of the biasing force of the adjusting spring imparted to the pressure adjusting device according to the temperature detected by the temperature sensitive device warrants outputting of continuously varying negative-pressure in response to the variation of the detected temperature.
