Propellant charge batch in particular for bolt setting tools

Abstract

A propellant charge batch for an explosion-operated setting tool includes a socket member ( 10 ) in an inner space which there are provided a first chamber ( 11 ) filled with a nitrocellulose propellant charge ( 13 ), and a second chamber ( 12 ) filled with an ammoniumnitrate powder ( 14 ), with at least the second chamber ( 12 ) being closed medium tightly; and at least one ignition element ( 15 ) for igniting the propellant charge.

What is claimed is:  
     
         1 . A propellant charge batch for an explosion-operated setting tool, composing: 
 a socket member ( 10 ) in an inner space of which there are provided a first chamber ( 11 ) filled with a nitrocellulose propellant charge ( 13 ), and a second chamber ( 12 ) filled with an ammoniumnitrate powder ( 14 ), with at least the second chamber ( 12 ) being closed medium tightly; and    ignition means ( 15 ) for igniting the propellant charge.    
     
     
         2 . A propellant charge batch according to  claim 1 , wherein the first and second chambers ( 11 ,  12 ) are arranged one after another in an axial direction ( 20 ) for the socket member ( 10 ).  
     
     
         3 . A propellant charge batch according to  claim 1 , wherein the ignition means ( 15 ) is provided in a region of a bottom ( 17 ) of the propellant charge batch, and wherein the first chamber ( 11 ) is arranged adjacent to the ignition means ( 15 ), and the second chamber ( 12 ) is arranged remotely from the ignition means ( 15 ).  
     
     
         4 . A propellant charge batch according to  claim 1 , wherein the batch is formed as a cartridge.  
     
     
         5 . A propellant charge batch according to  claim 1  further comprising an element ( 16 . 1 ,  16 . 2 ) for separating the first ( 11 ) and second ( 12 ) chambers.  
     
     
         6 . A propellant charge batch according to  claim 5 , wherein the separating element ( 16 . 1 ) is disc-shaped and is formed of a nitrocellulose board.  
     
     
         7 . A propellant charge batch according to  claim 1 , wherein the batch is formed as a blister.  
     
     
         8 . A propellant charge batch according to  claim 5 , wherein the separating element ( 16 . 2 ) is cup-shaped.  
     
     
         9 . A propellant charge batch according to  claim 8 , wherein the separating element ( 16 . 2 ) is formed of a stiff film material.
