Abstract

Il dispositivo (10) per l'accensione di una carica di polvere (58) mediante compressione approssimativamente adiabatica di aria presenta un involucro (12) in cui è disposta una camera di compressione (14). Nella camera di compressione (14) è condotto in modo mobile un pistone (22). I gas caldi compressi vengono convogliati tramite un foro di collegamento (46) ad una cartuccia (16) in cui è collocata una piastrina di accensione (48) e la carica di polvere (58). L'aria di compressione urta contro la piastrina di accensione (48) distruggendola in singoli frammenti. Dietro la piastrina di accensione (48) è disposta una camera di combustione (64) in cui i frammenti della piastrina di accensione (48) possono turbinare con l'aria calda di compressione. La camera di combustione (64) è separata dalla carica di polvere (58) da una parete divisoria (66) distruggibile. Attraverso la turbolenza del materiale della piastrina di accensione (48) con l'aria calda di compressione, il materiale di accensione viene acceso e bruciato in modo affidabile, in modo che la carica di polvere (58) venga innescata in modo sicuro.The device (10) for igniting a charge of powder (58) by means of approximately adiabatic air compression has a casing (12) in which a compression chamber (14) is arranged. A piston (22) is movably driven in the compression chamber (14). The compressed hot gases are conveyed through a connection hole (46) to a cartridge (16) in which an ignition plate (48) and the charge of dust (58) are placed. The compression air hits the ignition plate (48) destroying it in single fragments. Behind the ignition plate (48) there is a combustion chamber (64) in which the fragments of the ignition plate (48) can swirl with the hot compression air. The combustion chamber (64) is separated from the powder charge (58) by a destructible dividing wall (66). Through the turbulence of the ignition plate material (48) with the hot compression air, the ignition material is reliably ignited and burned, so that the charge of dust (58) is triggered safely.
