How Do Bayonet Connections Function in Cryostats for Liquid Helium Transfer?

[Rajini]

Dear PF,
What does this mean? .. Bayonet connection. It is used in cryostats..If anyone have some experience with such things..please explain me in details..
how does it work? etc...
thanks

Bayonet connection simply means one where you turn it through a small angle to engage/disengage rather than just pushing in on/off or screwing it in.

It doesn't really tell you enough to know what the connector is.

Do you have some idea of how these bayonet connection were employed in transferring liquid helium (in helium flow cryostats)..
