Coupling device for connecting a cartridge under pressure

摘要

The gas cartridge coupling has a central core (8), a ring (9), a cylindrical casing (16) and a rotational control plate (23). The pressure parts of the ring legs (19) consist of radial tenons (18) on the cylinder which are inserted in the gaps (20) in the unlocked position. The legs have an inner bearing surface (22) supported on one of the tenons and moved radially to the outside of its external notch (21). The ring is connected to the rotational control plate which has an angular travel limited between locked and unlocked positions.
