Abstract
The invention relates to a primer tube (1), notably for the propellant charge (4) of artillery ammunition (2). The primer tube (1) is formed of a tubular body (8) accommodating a priming composition (14). It is characterized in that the tubular body (8) incorporates at least one receiving surface (25) oriented so as to receive the propellant gas pressure generated when the propellant charge (4) is ignited, said gas acting to propel the primer tube (1). The pressure receiving surface (25) is a disk (20) arranged substantially radially to the tubular body (8).
Claims14
A primer tube for ensuring ignition of a propellant charge of artillery ammunition, said primer tube comprising:
- a tubular body;
- a priming composition located in said tubular body;
- a rear ignition unit located in said tubular body;
- a sleeve at a rear portion of the tubular body slidably covering the rear ignition unit;
- at least one pressure receiving surface for cooperating with said tubular body and for receiving propellant gas pressure generated when a propellant charge is ignited, for propelling the primer tube, wherein
- the pressure receiving surface comprises a disk integral with an upper end of the tubular body and extending radially outward from the tubular body, and
- said sleeve is for translating away from said rear ignition unit when propellant gas pressure is applied against said pressure receiving surface.
A primer tube and cartridge case for ensuring ignition of a propellant charge of artillery ammunition, said primer tube comprising:
- a cartridge case containing a propellant charge;
- a tubular body located inside the case;
- a priming composition located in said tubular body;
- a rear ignition unit located in said tubular body;
- a sleeve at a rear portion of said tubular body slidably covering the rear ignition unit;
- at least one pressure receiving surface for cooperating with said tubular body and for receiving propellant gas pressure generated when a propellant charge is ignited, for propelling the primer tube, wherein
- the pressure receiving surface comprises a disk integral with an upper end of the tubular body and extending radially outward from the tubular body, and
- said sleeve is for translating away from said rear ignition unit when propellant gas pressure is applied against said pressure receiving surface.
