1. A valve device for controlling the filling level of cylinders and the like with liquified gases, the device comprising:
- an upper connecting body which can be coupled to a cylinder for liquified gas, the upper connecting body having a tubular gas infeed element which terminates in a coupling body which associates with a lower connecting body in order to retain a membrane for closing openings for feeding gas into the cylinder, the device further including a valve control element which is controlled by a float and interacts with the membrane, the device including clinching means for mutual clamping of the upper connecting body and the lower connecting body, wherein the clinching means comprises a clinching collar provided with an annular portion which peripherally engages above the coupling body, the clinching collar having a plurality of tabs which protrude substantially axially and serve to clamp the upper and lower connecting bodies relative to one another.

Abstract
A valve device for controlling the filling level of cylinders and the likeith liquefied gases, comprising an upper connecting body which can be coupled to a cylinder for liquefied gas and forming a tubular gas infeed element which ends with a coupling body which is associable with a lower connecting body in order to retain a membrane for closing openings for feeding gas into the cylinder, and a valve control element which is controlled by a float and interacts with the membrane; the device further comprising clinching means for the mutual clamping of the upper connecting body and the lower connecting body.

6. A valve device for controlling the filling level of a gas cylinder, the device comprising:
-
an upper connecting body having a first end and an opposing second end, the first end for attachment to the gas cylinder, a portion of the upper connecting body being a gas infeed element which terminates with a coupling body at the second end; a lower connecting body which seats against the upper connecting body to form a chamber therebetween; a membrane disposed between the upper and lower connecting bodies, the membrane serving to selectively close openings for feeding gas into the cylinder; a valve control element disposed within the chamber, the valve control element being controlled by a float, the valve control element interacting with the membrane so that when no pressure is generated inside the chamber, the membrane is pushed downward until a preset filling level is reached at which time the valve control element descends resulting in the membrane being disposed hermetically against the second end of the upper connecting body; and a clinching collar for mutual clamping of the upper connecting body and the lower connecting body, the clinching collar having an annular portion which peripherally engages above the coupling body and a plurality of tabs protrude substantially axially and serve to retain the upper and lower connecting bodies relative to one another.
