Abstract
A device for controlling, in association with a stop valve, the gas stream delivered by a pressurized gas reservoir, whose casing is provided with an opening so that the inside of said reservoir may be connected to the outside. A cylinder is divided into a first chamber and a second chamber by a piston. The first chamber is in communication with the opening in the casing and includes an orifice which can be connected with the stop valve. A core is connected to the piston on the side thereof turned towards the first chamber. The core cooperating with the orifice so as to form a variable flow section as a function of the position of the piston in the cylinder. A passage with a non-return valve establishes communication between the first and second chambers of the cylinder. A controllable locking device is capable of locking the piston in the cylinder.
