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between a rest position, towards which it is resiliently biassed and in which it closes off the filling orifice, and a withdrawn position in which it lies within the bowl and in which the filling orifice is open. The valve is put into its withdrawn position by a filling nozzle when the latter is introduced into the filling orifice.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.

A filler head for a motor vehicle fuel tank filling pipe, comprising a bowl-shaped body having an upper face defining a filling orifice, a shut-off flap valve, pivot means mounting the shut-off valve to the body, for pivoting movement of said valve between a rest position in which the valve closes the filling orifice and a withdrawn position in which it lies within said body and wherein the filling orifice is then open; first resilient means carried in said body and connected to the shut-off valve for biassing the latter towards said rest position, whereby introduction of a filling nozzle through the filling orifice moves the shut-off valve to its withdrawn position against the action of the first resilient means; and automatic locking means in the body, comprising an unlocking control member and means for coupling the unlocking control member with the shut-off valve whereby to lock the latter in its rest position, wherein: the shut-off valve defines a lower face thereof; the body defines a seating around the filling orifice whereby said first resilient means urges the shut-off valve into engagement against said seating; the locking means comprises: at least one locking finger; a portion of said lower face of the shut-off valve adapted for receiving said at least one locking finger; second resilient means for urging the latter into engagement with said portion of the lower face of the valve so as to define a locking position; and means for moving the locking finger or fingers from said locking position to an unlocking position in which the locking finger is, or fingers are, laterally retracted from said portion of the lower face of the flap valve; wherein the automatic locking means comprise a locking arm having a first end portion, a second end portion, and a middle portion joining said first and second end portions, the said middle portion having a said locking finger, second end portion defining a control surface, the shut-off valve having a side edge, said body having an upper face for surrounding said side edge of the shut-off valve in the rest position of the edge of the latter, the body defining a pivot axis at right angles to its said upper face, the filler head further comprising means articulating a first end portion of a pivot arm to the body for pivoting of the locking arm about said axis, with said control member defining a control cam cooperating with said control surface of the locking arm.
