Abstract

Device for facilitating the correct screwing of a gas consumption device in a liquefied gas cylinder, especially a device that finds its specific application in gas consumption devices that are mounted directly in the threaded mouth of the shut-off valve automatic of a liquefied gas cylinder, such as lamps, stoves, stoves, etc., and comprising a coupling arrangement lower than said mouth formed by a threaded body, complementary to said mouth, which is provided inferiorly with an unblocking appendage of the automatic shut-off valve and crossed by an axial passage that reaches the shutter chamber of the regulating tap of the gas passage to the consumption apparatus, characterized in that the shutter of the automatic closing valve of the cylinder is connected to the threaded mouth of said closing valve through a fixed central guiding duct through which runs an emergent tubular stem, centered and axially, of the threaded body of the lower coupling arrangement of the consumer apparatus, said tubular rod having, peripherally at its free end, a sealing gasket and, centered and axially on its free base, an appendix the opening of said tubular rod has a length equal to the length of the central guiding duct and this length is such that it allows inserting the sealing gasket of the tubular rod at the beginning of said central guiding duct according to a pointing position., which determines a guiding and sealing position prior to the beginning of the threading of said lower coupling arrangement, in which the axis of the threaded body of said coupling arrangement coincides with the axis of the threaded mouth of the shut-off valve of the liquefied gas cylinder, this situation being maintained during the entire operation of screwing.
