Svivelkoppling för reglering av lufttryck i fordonsdäck

摘要

A swivel connection is provided for the regulation of air pressure in a tire of a vehicle. The connection includes first and second ring-shaped members concentrically arranged. The first ring-shaped member rotates with the tire while the second ring-shaped member is fixed to the vehicle. A duct communicates air between an air pressure unit and the interior of the tire via a conduit including an annular seal having circumferentially spaced holes for transmission of air to and from the tire. A ball bearing enables the relative rotation of the first and second ring-shaped members.
