<p>A method and apparatus for bead seating a tubeless tire onto a rim. Air stored in a portable tank is released as a single pneumatic pulse having an extremely fast rise time. This is accomplished using a charging reservoir having a fill/quick-release port, an inlet and an outlet. A piston divides the charging reservoir into two sections, a control section containing the fill/quick-release port and an outlet section containing the inlet and the outlet. The portable tank is connected to the inlet of the outlet section. Air that is introduced into the fill/quick-release port fills the control section of the charging reservoir. Since the piston is a loose fit, air is able to slowly leak past the piston and fill the outlet section of the charging reservoir and the portable tank that is connected to the inlet. The pressure differential across the piston keeps the piston tightly against the outlet, holding the pressurized air in the outlet section and the portable tank. Once the pressurized air in the quick-release section is released, the pressure differential is reversed and the piston is propelled away from the outlet, thereby explosively releasing the air from outlet section and the connected portable tank as a single pneumatic pulse. The pneumatic pulse is directed between the rim of the wheel and the bead of the tire by a unique nozzle to seat the bead of the tire.</p> |
