POWDER INJECTION SYSTEM FOR DETONATION-OPERATED PROJECTION GUN

The powder injection system is comprised of a dosing chamber (2) which is directly supplied by a conventional powder supplier (7) and communicates with the barrel (1) of the detonation gun through a direct conduit (5). Thus, the pressure wave which progresses through the barrel (1) enters through th...

Beschreibung
Zusammenfassung:	The powder injection system is comprised of a dosing chamber (2) which is directly supplied by a conventional powder supplier (7) and communicates with the barrel (1) of the detonation gun through a direct conduit (5). Thus, the pressure wave which progresses through the barrel (1) enters through the communication conduits (5) and, when reaching the dosing chamber (2), is subjected to a sudden expansion which stops the powder supply from the continuous supplier (7) and produces the complete fluidification of the powder contained in the dosing chamber (2). The fluidized powder will then be entrained by suction up to the barrel (1) where it resides until the pressure wave generated in a new detonation cycle entrains said powder to deposit it to the surface of the part to be coated.
