Definitions

  • the invention relates to a powder-operated setting device with a barrel having a combustion chamber, a discharge channel connected to the combustion chamber for the propellant gases generated in the barrel and a regulating slide for adjusting the cross-section of the mouth of the discharge channel.
  • the regulating slide is designed as a closing piston for the outflow channel that can be moved by a handle parallel to the main axis of the barrel.
  • the outflow channel By moving the sealing piston parallel to the main axis of the barrel, the outflow channel can be opened or closed continuously. It is advisable to arrange the outflow channel radially in the rear region of the barrel, for example in the form of an elongated hole, this elongated hole being able to be traversed by a guide bore for the sealing piston transversely to its radial alignment.
  • a power regulation which uses a locking piston which is displaceable in the aforementioned sense, is particularly simple in construction since it does not require any complicated work processes in the production of the individual device parts.
  • sealing piston of the aforementioned type offers the possibility of solving the contamination problem in a simple manner by expediently the sealing piston having sharp-edged transitions to sealing surfaces. Since the cylinder jacket surfaces act as sealing surfaces in a sealing piston, the ends of the sealing surfaces, for example at the end of the sealing piston or at a transition to a reduction in diameter, can be seen as sharp-edged transitions here. Moving the sharp-edged transitions along the mouth of the outflow channel results in cleaning by stripping off any residues of the propellant gases that have been set.
  • the locking piston preferably has a thread that is connected to the handle.
  • This offers the possibility, for example, of designing the handle as an adjusting wheel that can be operated from the outside of the setting tool, so that by turning this adjusting wheel, thanks to the threaded connection, an exactly adjustable axial adjustment of the locking piston is achieved.
  • a sufficient fine adjustment of the locking piston is made possible, so that the performance of the setting tool can be dosed with sufficient accuracy.
  • a housing 1 with a laterally projecting handle 2 and a trigger 3.
  • a barrel 4 with a mouth part 5 attached to it on the setting direction is slidably mounted in the housing.
  • a driving piston 6 is arranged, which in the Mouth part 5 protrudes.
  • the end of the running bore 4a lying behind the driving piston 6 against the setting direction forms a combustion chamber together with a cartridge bearing 4b.
  • a per se known ignition pin 7 can be actuated in a manner known per se for the ignition of cartridges located in the cartridge bearing 4b.
  • the bore 4a is laterally connected to an outflow channel 4c in the form of an elongated hole penetrating the wall.
  • the outflow channel 4c is penetrated in the setting direction by a bore 4d, the diameter of which projects beyond the width of the gap.
  • a locking piston 8 which is mounted so as to be displaceable in the setting direction, projects into the bore 4d and, depending on the axial position, is able to change the cross-section of the mouth of the outflow channel 4c.
  • the locking piston 8 has a section 8a with a reduced diameter in the area protruding into the bore 4d.
  • the length of the section 8a corresponds to the length of the outflow channel 4c.
  • Sealing surfaces 8b corresponding to the diameter of the bore 4d adjoin the section 8a on both sides. The transitions of the sealing surfaces 8b are sharp-edged.
  • the locking piston 8 In the area located in the housing part 1a, the locking piston 8 carries a transverse pin 8c, which projects into a longitudinal groove 1b in the housing part 1a and thus prevents the locking piston 8 from rotating. Contrary to the setting direction, a thread 8d connects to the cross pin 8c.
  • An adjusting wheel 9 is seated on the latter in the housing 1a so that it cannot be moved.
  • the adjusting wheel 9 has a knurl 9a on the outside for easier turning operation.
  • the adjusting wheel 9 is rotated to regulate the power of the setting tool.
  • the closing piston 8 moves in or against the setting direction, as a result of which the mouth cross section of the outflow channel 4c is adjusted.
  • more or less propellant gas can flow from the combustion chamber into the room to escape between the barrel 4 and the housing 1, so that sound insulation is additionally achieved.
  • the barrel 4 is pulled forward in the setting direction to remove the remnants of the cartridge and, after being fitted with a new cartridge, is brought back into the position shown.
  • the sealing piston 8 with the sharp-edged transitions frees the bore 4d from residues caused by the propellant gases each time.
  • the power regulation remains functional in the long run.
