TANKDECKEL FÜR MOTORFAHRZEUG.

摘要

A filler cap (10) for a motor-vehicle fuel tank comprises a cylindrical main body (12) on which is slidably mounted a shaped bush (26) adapted to squeeze a sealing ring (28) against a flange (12a) of the body (12). This axial squeezing causes a radial expansion of the sealing ring (28) adapted to form a seal between the cap (10) and the filler pipe (B).
