ABSTRACT:
A cap for the pipe of an automobile radiator or the like includes a pressure/vacuum valve. The pressure at which the valve opens may be adjusted by an easily operated means permitting adjustment of the compression of a pressure spring, thereby making it possible to reduce the effect of spring tolerances on opening pressure tolerances.
