Abstract
A device for securing a plug, of the type involving a piston ( ) propelled by gas, has a combustion chamber ( ) delimited on one side by the piston and on the other side by a cylinder head ( ) with a duct ( ) for injecting combustible gas open via one end ( A) into the chamber. The duct ( ) has an orifice for creating a pressure drop between the part of the duct ( ) upstream of the end ( A) and the chamber ( ) itself, so as to at least partially avoid the vaporizing of the combustible gas in the part of the duct upstream of the end.
