COUPLING DEVICE FOR CONNECTING GAS EQUIPMENT WITH GAS CARTRIDGE Russian patent published in 2010 - IPC F16L37/133 F17C13/00 

FIELD: machine building.

SUBSTANCE: invention refers to devices for connecting gas equipment with valve of gas cartridge. The device consists of a tap case made as a whole with the gas equipment, of an axial conjugating ring made as a whole with the tap case and having at least one flexible foot designed to be engaged with a circular groove of the cartridge valve in radial direction. A fixing swivelling ring can be set in a fixing position whereat the swivelling ring ensure engagement of each flexible foot with the groove; it also can be set into a position of disengagement when the swivelling ring disengages each flexible foot (4) from engagement with the groove. The cylinder is equipped with a tube removing the locking element of the valve. The fixing swivelling ring has a radial facility of conjugation interacting with a complementary radial device of conjugation arranged on the valve of the gas cartridge owing to which the device transfers from the position of fixation to the position of disengagement at the turn of the cartridge.

EFFECT: increased reliability of connecting device coupling.
