  • Pressure gauge
    Patent number: 4096760
    Abstract: A pressure gauge comprising a rigid housing in which a gauge member is located whose interior is subjected to the pressure to be measured. The housing includes a pressure equalizing device in the form of a cup-shaped resilient membrane or a resilient bellows which is subjected to the interior pressure of the housing on the one side and to the ambient pressure on the other side. Furthermore, a closure element which can be blown out is snapped into position in an opening in said housing. The pressure equalizing device is secured to said closure element and is supported by it, thereby simplifying the installation of said pressure equalizing device in the housing.
