  • Method of determining the zero-clearance pressure in a controlled clearance piston gauge
    Patent number: 7628055
    Abstract: A method of determining the zero clearance pressure in a controlled clearance piston gauge. The typical method includes pressurizing the cylinder in which the piston resides to a given system pressure. The jacket pressure is then changed and the exhaust gas pressure build-up rate at different jacket pressures is measured. The zero clearance pressure to be where the exhaust gas pressure build-up rate is zero.
    Type: Grant
