Filler head for a motor vehicle fuel tank filling pipe

摘要

A filler head for a motor vehicle fuel tank filling pipe has a bowl-shaped body, the upper face of which includes a filling orifice. A shut-off valve is pivoted to the bowl of the body between a rest position, towards which it is resiliently biassed and in which it closes off the filling orifice, and a withdrawn position in which it lies within the bowl and in which the filling orifice is open. The valve is put into its withdrawn position by a filling nozzle when the latter is introduced into the filling orifice. The filler head has automatic locking means for locking the shut-off valve in its rest or closed position, with these locking means comprising an unlocking control member.
