| 摘要 | A pneumatic tire (1) comprising a tire cavity (11), sidewalls (7) extending from tire bead regions (9) to a tire tread region (5), an elongate annular air passageway (15) enclosed within a bending region of the tire (1) and extending substantially in a circumferential direction of the tire (1), and a valve assembly (17) in air flow communication with the tire cavity (11), the air passageway (15) and the exterior (19) of the tire (1) is disclosed. The valve assembly (17) comprises an air inlet (20) for allowing air to enter the valve assembly (17) from the exterior (19) of the tire (1), an air outlet (30) for allowing air to enter the tire cavity (11), a first valve (22) interposed in the air flow of the air passageway (15), the first valve (22) having a first position allowing air to enter the air passageway (15) through the air inlet (20) in a first flow direction and a second position allowing air to enter the air passageway (15) through the air inlet (20) in a second flow direction opposite to the first direction, and a second valve (32) interposed in the air flow of the air passageway (15) in parallel to the first valve (22). When the first valve (22) is in the first position, the second valve (32) is in a third position allowing air flowing through the air passageway (15) in the first flow direction to exit the air passageway (15) through the air outlet (30). When the first valve (22) is in the second position, the second valve (32) is in a fourth position allowing air flowing through the air passageway (15) in the second flow direction to exit the air passageway (15) through the air outlet (30). | ||||||
