20110120611 | AUTOMATIC INFLATOR AND METHOD FOR MAINTAINING A TIRE PRESSURE - An apparatus and method are described for extracting useful work from pressure transients in a pneumatic tire to replace lost air from the tire. The apparatus and method operate continuously and without human intervention. When also used with a pressure relief valve, the apparatus and method permit the tires that are being driven to be maintained at a desired average pressure. | 05-26-2011 |
20120073716 | DISTRIBUTED PUMP SELF-INFLATING TIRE ASSEMBLY - A self-inflating tire assembly includes one or more air tube(s) connected to a tire and having a plurality of adjoining diaphragm chambers separated by a one-way valve. An air passageway extends through the air tube and the diaphragm chambers. The one-way valve allows a directional passage of air through the valve from an inlet valve side an outlet valve side. The footprint in a rotating tire sequentially collapses the diaphragm chambers to directionally pump air through the one-way valve between the diaphragm chambers and along the air passageway from an air tube inlet device to an air tube outlet device. | 03-29-2012 |
20120090752 | SELF-INFLATING TIRE ASSEMBLY - A tire assembly includes a tire carcass body and an air tube body extending between an outward facing tire body surface and an inward tire body surface. The air tube body has an enclosed hollow enclosed outlet end at a first end and an enclosed hollow inlet end at an opposite second end. An air passageway extends through the air tube body from the inlet end to the outlet end. The outlet end is positioned to face exposed from the outward tire body surface and the inlet end is positioned to face exposed from the inward tire body surface. The air tube body is integrally formed of resilient flexible material composition and includes a hollow outer casing and one or more hollow air cables positioned within the casing for regulating the rate of air flow from the inlet end to the outlet end. The air tube body may follow a non-linear U-shaped path that surrounds a tire body bead core between the outward tire body surface and the inward tire body surface and be incorporated into the green tire build without disrupting the tire building and curing process or compromising the structural integrity or form of any of the green tire building components. | 04-19-2012 |
20120090753 | TIRE AND SELF-INFLATION APPARATUS ASSEMBLY - An air passageway body resides within a tire body and extends between an outward facing tire body surface and the tire cavity, the air passageway body having an enclosed air passageway extending between a hollow body outlet end facing the tire cavity and a hollow inlet end facing outward from the outward facing tire body surface. A tapping device is affixed over one or both of the ends of the air passageway body, the tapping device having an external vent opening and a protrusion member penetrating through a sidewall of the air passageway body to operatively establish an air flow path extending between the air passageway of the air passageway body through the protrusion member and the tapping device vent opening. The air passageway body is installed pre-cure within a green tire carcass build of the tire body and the tapping device(s) are attached post-cure to the air passageway body. | 04-19-2012 |
20120125504 | IN-LINE PUMPING ASSEMBLY FOR SELF-INFLATING TIRE - A tire for a self-inflating tire system includes a tire carcass having an annular air tube-receiving groove formed within a tire carcass wall and a pump assembly within the groove. The pump assembly includes an air tube having an axial air passageway; an inlet device positioned along the air tube, the inlet having a tubular inlet body having an internal air passageway aligned with the air tube and having at least one inlet opening extending through the inlet body for admitting air into the tubular inlet body. The inlet device further includes an air filtering sleeve at least partially surrounding the inlet opening of the inlet device, the sleeve having a tubular sleeve body at least partially surrounding and in co-axial relationship the tubular inlet body. The pump assembly further includes an outlet device positioned in-line along the air tube, the outlet device having a tubular outlet body and an axial passageway in-line with the air tube and having at least one outlet passage tube from the outlet device through the carcass wall to the tire cavity. | 05-24-2012 |
20120160386 | PUMP AND ACTUATOR ASSEMBLY FOR A SELF-INFLATING TIRE - A self-inflating tire system includes a compression actuator assembly mounted to a tire carcass for compressing air for delivery to a tire cavity. The compression actuator assembly includes a hollow containment body formed from a resilient deformable material composition and containing a quantity of a non-compressible medium. The containment body is affixed to a relatively high flex-deformation region of the tire carcass and reciprocally transforms between a deformed state and a non-deformed state responsive to deformation and recovery of the tire high flex-deformation region in a rolling tire. Accordingly, the containment body in the deformed state displaces a pressurized displaced quantity of the non-compressible medium which generates a compression force for application to a volume of air delivered to the tire cavity. A pump assembly affixes to the tire carcass and includes valves for reciprocally opening and closing the inlet opening and the outlet opening of a compressor body synchronously with the cyclic transformation of the containment body. | 06-28-2012 |
20130092306 | Cap For A Valve Stem - A cap for a valve stem includes a housing extending along an axis from a first end to a second end. A bore extends along the axis from the first end toward the second end and a cup-shaped wall extends circumferentially about the bore for receiving the valve stem. A threaded surface is disposed in the bore for threadedly engaging the valve stem. A flange extends from the first end transversely to the axis and circumferentially around the bore for abutting the rim of the wheel to stabilize the housing relative to the rim of the wheel. Ribs are radially spaced about the housing and extend outwardly from the wall of the housing to the flange reinforcing the housing relative to the flange. | 04-18-2013 |
20140110029 | 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. | 04-24-2014 |
