FIELD: automotive industry.
SUBSTANCE: invention relates to the automotive industry. Seal comprises fixed part, rotating part, first sealing ring, second sealing ring, and also first sleeve. Fixed part limits the first air passage passing through it, and the rotating part limits the second air channel passing through it. Each of sealing rings is located either on rotating part, or on fixed part. First bushing is located either on the rotating part or on the fixed part and is in contact with the first sealing ring, thus forming a dynamic seal. Fixed part, the rotating part, the first sealing ring and the second sealing ring form a tight cavity connecting the first air channel with the second air channel.
EFFECT: simplified installation of centralized tire pumping system.
