    Abstract: An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, a pressure control assembly attached to an elongate valve stem projecting from a rim, the pressure control assembly being external to the tire cavity, the elongate valve stem projecting outward from the tire cavity and operative to admit pressurized air into the tire cavity through the pressure control assembly, the first sidewall having an annular sidewall air passageway therein operatively located to compress segment by segment responsive to a bending strain introduced into the first sidewall from a rolling tire footprint thereby forcing air, segment by segment, along the annular air passageway, a tube housing joining both ends of the annular air passageway, and a connecting tube extending from the tube housing to the pressure control assembly, the connecting tube operative to sequentially direct air forced along the air passageway, first, into the tube housing, the pressure control assembly and, then, into the elongate valve stem as the tire rolls over a ground surface.

    Abstract: An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, air pumping means for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, and a faceted valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity. The first sidewall has at least one bending region operatively bending within a rolling tire footprint and a sidewall groove defined by groove sidewalls positioned within the bending region of the first tire sidewall. The groove deforms segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the first sidewall bending region within the rolling tire footprint.
