Embodiment Construction

[0078] refer to figure 1 , tire and air maintenance pump assembly 10 (forming an air maintenance tire or “AMT”) includes a tire and vascular pump assembly 28 . US Patent Nos. 8,113,254 and 8,042,586 describe the general operation of peristaltic pumps used in tires, both filed on December 12, 2009 and filed on February 14, 2012 and October 25, 2011, respectively. Issued on , and is incorporated herein by reference in its entirety. The tire is constructed to provide a tread region 14 , a pair of sidewalls 16 , 18 extending from opposing bead regions 22 , 24 to the tire tread region 14 . The tire encloses the tire cavity 20 . The air maintenance assembly includes an elongated air tube 26 enclosing an annular passage 28 . Tube 42 is formed from a resilient, elastomeric, flexible material, such as plastic or rubber compounds and compositions, which is capable of withstanding repeated deformation cycles in which the tube is deformed into a flat state by an external force and when...

Abstract

The invention relates to a vein pump assembly for an air maintenance tire, specifically to an air maintenance tire and air pump assembly 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.

Description

technical field [0001] The present invention relates generally to air maintenance systems for tires, and more particularly to systems that secure an air pump device to a tire that maintains air pressure within the tire as the tire rotates. Background technique [0002] Normal air diffusion will reduce tire pressure over time. The natural state of a tire is to be inflated. As a result, drivers must repeatedly act to maintain tire pressure or they will observe reduced fuel economy and tire life as well as reduced vehicle braking and handling performance. Tire pressure monitoring systems have been proposed to warn the driver when tire pressure becomes significantly low. However, such systems still rely on the driver to take remedial action to re-inflate the tires to the recommended pressure when alerted. Therefore, it is desirable to incorporate a self-inflation feature into the tire that will self-inflate the tire to compensate for any drop in tire pressure over time withou...
