<p>Filling connector comprising a body (2) defining an internal filling circuit (6) between an upstream end (3) for connecting to a filling outlet and a downstream end (4) for connecting to a container, the connector comprising an isolation valve element (7) able to move relative to a seat (8) between an upstream position in which the circuit (6) is closed and a downstream position in which the circuit is open, the said isolation valve element (7) being urged into its upstream position by a return member (9), the connector further comprising a dust valve element (10) positioned upstream of the isolation valve element (7), the said dust valve element (10) being able to move relative to the body (2) between an upstream position in which the upstream end of the circuit (6) is closed and a downstream position in which the upstream end of the circuit is open, the said dust valve element (10) being urged into its upstream position by a return member (14), characterized in that the isolation valve element (7) comprises a nonreturn mechanism (7, 177) generating a force on the isolation valve element (7) that urges it in the upstream direction when this valve element is subjected only to a fluidic pressure in its upstream part, and in that when the said dust valve element (10) is in a set downstream position, a downstream end (101) of the dust valve element (10) comes to press against an upstream end (107) of the moveable isolation valve element (7) to move the isolation valve element (7) into its downstream position.</p> |
