Closure for vehicle fuel tank filling spout - has coaxial adjusting ring at neck with spiral teeth meshing with lever arm on closure and has pivot bearing working with radial recess to lock and unlock catch

摘要

The filling spout (1) has an adjusting ring (12) coaxial and rotating on its outer surface, and/or its axial front face. The ring has a spiral toothing (13) at least over a section of its upper side. The lever arm (9) on the closure cover (8) has a toothed segment (10) which meshes with the ring, such that turning the adjusting ring produces a force on the closure in the opening or closing sense. A pivot bearing (16) for the lock catch (17) on the adjusting ring works together with a radial recess (18) to give free pivoting of the catch. ADVANTAGE - Guarantees reliable and durable closure function.
