CYLINDER VALVE ASSEMBLED BY PERMANENT DEFORMATION AND CYLINDER HAVING A VALVE ASSEMBLED BY PERMANENT DEFORMATION

摘要

The invention relates to a cylinder valve (102) that includes a body (104) having a hollow portion defining a generally cylindrical wall (116) for tightly receiving a generally cylindrical member (118). The wall (116) is deformed by a method that uses a magnetic pulse that can be pressed against the member (118), which results in a cold weld providing a link having an exceptional mechanical strength and that is very easy to implement. Similarly, the invention relates to a cylinder for compressed gas, which comprises a neck de fining a generally cylindrical wall and receiving a generally cylindrical portion of the body of a valve at the inlet thereof. The wall (116) is deformed by a method that uses a magnetic pulse that is pressed against the body, which results in a cold weld providing a link having an exceptional mechanical strength and very easy to implement.
