Abstract
An air maintenance tire assembly having an elongate air pumping sidewall air passageway includes an inlet air passage screw assembly inserted through a tire sidewall profiled bore to conduct air from outside the tire into a regulator positioned within a tire cavity. The screw assembly includes a screw body having at an outer end a large-diameter filter housing, a smaller-diameter midsection shank portion, and an inner large-diameter valve housing connecting to the regulator within the tire cavity. A valve mechanism seats within the valve housing and moves between an open position conducting air from the screw body into the regulator assembly and a closed position preventing a backflow of air from the regulator assembly.
