Filling connector comprising a body () defining an internal filling circuit () between an upstream end () and a downstream end (), with the connector comprising an isolation valve element () mobile relatively to a seat () between an upstream position in which the circuit is closed and a downstream position in which the circuit is open, with the connector () further comprising a dust valve element () positioned upstream of the isolation valve element (), characterised in that the dust valve element () can be moved selectively towards downstream either:

Filling connector, container, filling method and filling nozzle

A method for withdrawing a pressurized gas from a receptacle comprising a tap, the tap comprising a filler/withdrawal coupling for a pressurized gas receptacle designed to interact with a packaging connector in order to allow said receptacle to be filled with pressurized gas or for withdrawal of pressurized gas from the receptacle, the method comprising

Filler coupling and corresponding receptacle and filling method

A filler-withdrawal coupling for a pressurized gas receptacle comprising a body defining an internal filler circuit between an upstream end designed to be connected to a packaging connector and a downstream end designed to be connected to a receptacle, the coupling comprising an isolation valve that can move relative to a seat between an upstream position for closing the circuit and a downstream position for opening the circuit, said isolation valve being moved to its upstream position by a return member, the coupling also comprising a dust-prevention valve placed upstream of the isolation valve, said dust-prevention valve being able to move relative to the body between an upstream position for closing the upstream end of the circuit and a downstream position for opening the circuit upstream end, said dust-prevention valve being moved to its upstream position by a return member.
