A filler for a fuel tank with an automatic pressure venting device

摘要

A filler for a fuel tank has a valve with a body which is integral with the tubular body of the filler and has a shutter which is operated by a cam section on the fuel cap when the latter is rotated before being removed. This rotation enables the excess pressure in the filler to be vented immediately before the cap is removed. The nozzle also has an integral seat for an anti-evaporation valve, as well as a seat for a safety valve.
