Abstract
The pressure gauge is designed for operative engagement with a gas pressurized system such as a pneumatic tire. It includes a housing having a pressurized gas inlet orifice and a cylindrical bore formed within the housing. A pressure reactive piston is slidably engaged within the cylindrical bore, and a resistance means is disposed within the cylinder to provide a resistive force to the movement of the piston. A calibration rod is disposed proximate the piston, whereby movement of the piston will cause movement of the rod. A pressure indicator bar, which is threadably engaged to the rod, provides an indication of the pressure level of the gas. The calibration rod has a user accessible end, and rotation of the rod causes a calibration adjustment of the pressure indicator bar due to the threaded engagement of the rod with the pressure indicator bar.
