Fuel tank cap for motor vehicle

摘要

The filler cap (1) has a barrel lock (17) with a stator (18) and a rotor (19) operated by a key (22) and fixed by locking elements (33) when the cap is in place on the filler pipe and locked. The cap incorporates a mechanism (11,34) which holds the key, which is also the ignition key, in place in the rotor while the cap is removed from the filler pipe, and retracts to release the key when the cap is locked on the pipe. The lock barrel stator is designed to rotate together with a plate (3), while the rotor turns together with a support (23) and in relation to the stator. The key can only be inserted or removed when the rotor and stator are in the correct relative positions.
