Filling connector, container, filling method and filling nozzle

A filling connector for a container of fluid under pressure intended to cooperate with a filling outlet in order to allow for the filling of said container, the connector (1) comprising a body (2) defining an internal filling circuit (6) between an upstream end (3) intended to be connected to a filling outlet and a downstream end (4) intended to be connected to a container, the filling connector comprising

• a) an isolation valve element (7) mobile, relative to a seat (8), between an upstream position in which the circuit is closed and a downstream position in which the circuit is open, said isolation valve element (7) being urged into its upstream position by a return member (9),
• b) the filling connector (1) further comprising a dust valve element (10, 100) positioned upstream of the isolation valve element (7), said dust valve element (10, 100) comprising a downstream end (101) and being mobile, relative to the body (2), between an upstream position in which the upstream end (3) of the circuit (6) is closed and a downstream position in which the upstream end (3) of the circuit is open, said dust valve element (10, 100) being urged into its upstream position by at least one return member (14, 140),
• c) wherein the dust valve element (10, 100) can be moved selectively heading downstream either:
• in a first set downstream position referred to as “without contact” which opens the upstream end (3) of the circuit (6), wherein the downstream end (101) of the dust valve element (10, 100) does not push the upstream end (107) of the isolation valve element (7), the upstream end (107) of the isolation valve element (7) being able to be pushed towards its downstream position in which the circuit (6) is open by fluid under pressure entering through the upstream open end (3) of the circuit (6), or in
• a second set downstream position referred to as “contact” which opens the upstream end (3) of the circuit (6), wherein the downstream end (101) of the dust valve element (10, 100) pushes an upstream end (107) of the mobile isolation valve element (7) in order to move via contact the isolation valve element (7) towards its downstream position in which the circuit (6) is open and in that the dust valve element (10, 100) comprises a passage or passages (103) in order to guide at least some of the flow of fluid transiting from upstream (3) to downstream (4) through the body of said dust valve element (10), and
• d) wherein the dust valve element (10, 100) comprises a first (10) and a second (100) concentric parts able to be moved in relation to one another according to the upstream-downstream direction.
