Open the CIPO recordAbstract From the Canadian patent
An apparatus (10) for inflating larger tubeless tires (80), such as those utilized on farm tractors includes a segmented manifold (104) which is expandable radially to accommodate different sizes of tires. The segmented manifold (104) includes outlet holes (36) from which pressurized gas may exit to inflate the tire (80). The holes (36) have centerlines which make angles generally between 40 and 75 with a plane containing the manifold (104). The angled holes (36) direct the pressurized gases exiting the manifold in optimum directions to expand the tire sidewall against the wheel flange (92) to assist in sealing the tire beads against the wheel (82).
