  • Patent number: 5855221
    Abstract: A tire deflator includes a tubular housing with indicia markings showing a desired terminal pressure to preset a tire to a desired air pressure. Click stops are provided at air pressure intervals via indentations, which interact with springy pointer. A cap with a threaded cap is moved to move the cap to the desired click stop indentation. A hose terminates in a pneumatic chuck which attaches the tire deflator to a tire valve. In operation, the user simply turns the threaded cap relative to the tubular housing to the desired terminal pressure "click stop", as indicated by numbers on the tubular housing. The user then attaches the hose chuck to the tire valve by using the handle to lock on; the chuck has an internal pin which forces open the tire valve. The deflation process commences when pressure release pin on the bottom of the deflator is pressed in so that it snaps to its inward stable position.
