20150059952 | FILTER ASSEMBLY FOR AIR MAINTENANCE TIRE - A tire assembly is disclosed, wherein the tire has a tread portion and a pair of sidewalls extending radially inward from the tread portion to join with a respective bead; a supporting carcass for the tread portion and sidewalls; and a pump passageway positioned within a bending region of the tire. The pump passageway is operative to open and close as the tire rotates. The tire assembly further includes a valve assembly in fluid communication with the pump passageway. The tire further includes a pocket formed in the tire, and a filter assembly is mounted in the pocket. The filter assembly is in air flow communication with the valve assembly, wherein the filter assembly is formed of a housing and a cover, wherein the cover has one or more holes for communicating air into the housing, wherein the cover is connected to the housing, the housing having an interior cavity having a filter media housed therein, the housing having a hole in fluid communication with the valve assembly, wherein a flexible collar surrounds the cover. | 03-05-2015 |
20150306924 | VEIN-STYLE AIR PUMPING TUBE AND TIRE SYSTEM AND METHOD OF ASSEMBLY - An air pumping tube and tire system and method of assembling is provided in which a tire groove is formed to extend into a flexing region of a tire sidewall and a complementary air pumping tube inserts into the tire groove. In the green, uncured air pumping tube condition, one or more check valves are assembled into the air pumping tube through access shafts and align with an internal air passageway of the air pumping tube. Plug components of the system enclose the check valves in the air pumping tube and the check valve-containing green air pumping tube is then cured. | 10-29-2015 |
20150375575 | VEIN PUMP ASSEMBLY FOR AIR MAINTENANCE TIRE - An air maintenance tire and air pump assembly is provided including a tire and an elongate tubular air passageway enclosed within a flexing region of a tire sidewall. A plurality of check valve devices are spaced apart and positioned along the air passageway into multiple air passageway segments. A check valve membrane opens to allow pressurized air to directionally pass through the check valve device from an upstream passageway segment to a downstream passageway segment and closes to prevent air from passing in an opposite direction through the check valve from the downstream segment to the upstream segment. | 12-31-2015 |
20160039258 | PASSAGE TUBE FOR AIR MAINTENANCE TIRE - The present invention is directed to a tire assembly having: a tire having a tread portion and a pair of sidewalls extending radially inward from the tread portion to join with a respective bead; a supporting carcass for the tread portion and sidewalls; a pump passageway positioned within a bending region of the tire, the pump passageway being operative to open and close as the tire rotates; a valve assembly in fluid communication with the pump passageway; a pocket formed in the tire; a filter assembly mounted in the pocket, said filter assembly being in air flow communication with the valve assembly, wherein the pocket has an area larger than the area of the filter housing wherein the valve assembly has an inlet, wherein the filter assembly has an outlet, wherein a tube connects the filter outlet assembly to the inlet of the valve assembly; wherein the tube is made of a rubber composition having a shore D hardness greater than 40 as measured by ASTM-D2240. | 02-11-2016 |
20160052350 | AIR MAINTENANCE PUMPING ASSEMBLY AND TIRE - A tire assembly includes a tire having a pneumatic cavity, first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region with the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint, and a chafer component with an air passageway defined by an air tube resiliently deforming segment by segment between an expanded condition and an at least partially collapsed condition in response to respective segment by segment deformation of the sidewall when radially within the rolling tire footprint. The air tube is inserted into the chafer before assembly with other components of an uncured tire and curing of the uncured tire. | 02-25-2016 |
