Abstract
The invention relates to a system for the supply of compressed air to the tire of a commercial vehicle by way of a duct system leading through a non-rotary first member into an annular space and then into a rotary second member. The annular space is formed between a receiving sleeve in the rotary member and a race ring on the non-rotary member and is delimited by axially spaced, coaxial seals which may be shaft labyrinth seals or seals making sliding contact.
