ABSTRACT:
The invention pertains to a high production tire inflator apparatus for rapidly inflating tubeless tires wherein sealing between the tires and the wheels occurs at the tire beads. A tandem expansible chamber motor unit utilizing compressed air and hydraulic pressurized fluid vertically translates a carriage upon which an annular tire seal is mounted for displacement between tire indexing, sidewall displacement and bead seating positions, compressed air being used to displace the tire seal during rapid transverse movement, and the hydraulic fluid motor being employed to lock the tire seal to resist inflation pressures during pressurization of the apparatus. The wheel and tire are mounted upon a conveyor pallet which is of such configuration to directly sealingly engage the lower tire sidewall, and during inflation all sealing occurs between the tire sidewalls and the inflation apparatus, and no sealing of the wheel rim is required.
