Abstract
A propellant gas sealing device for gun munitions includes a piston attached to the rear of a projectile by a separable connecting device, and a piston that isolates the projectile from the propellant charge. A low pressure seal carried by the piston is designed to ensure the gastightness between the piston and the gun chamber, and a high pressure obturator carried by the piston is designed to ensure the gastightness between the piston and the gun barrel.
Claims8
A propellant gas sealing device for gun munitions having a projectile and a propellant charge, said sealing device comprising:
- a piston separably attached to a rear of a projectile, said piston serving to isolate the projectile from a propellant charge;
- a low pressure seal mounted on the piston to ensure an airtight fit between the piston and a gun chamber;
- and
- a high pressure obturator connected to the piston to ensure an airtight fit between the piston and a gun barrel.
