Definitions

  • the invention relates to a powder-operated setting tool according to the preamble of Claim 1.
  • a powder-operated setting tool is known, the one Guide cylinder with an inner bore in which a driving piston axially displaceable is arranged.
  • a substantially coaxial with the guide cylinder arranged butt plate closes against the setting direction on the guide cylinder on.
  • This butt plate has a cartridge bearing in a setting direction End range on. The clear width of the cartridge storage increases towards the free end of the push floor.
  • the guide cylinder has an end region pointing counter to the setting direction an annular cutout in which an annular sealing element is arranged is.
  • the circular cut-out divides the opposite of the setting direction facing end portion of the guide cylinder in a central cylindrical portion and an annular one surrounding this cylindrical portion at a distance outer section.
  • the free end of the central section forms a counter surface, with which a cartridge inserted in the cartridge store can be fixed.
  • the counter surface dominates the remaining part of the end face against the setting direction.
  • the propellant gas pressure generated when the cartridge is ignited comes from the cartridge store via a connecting channel to an inner wall of the annular Sealing element with a U-shaped cross section, the opening of which to the central longitudinal axis of the sealing element is open.
  • the LPG pressure generated by the cartridge does not work entirely in the setting direction on this known setting tool Sealing element, but in two opposite, parallel to the direction of setting Directions, so that a widening of the sealing element in two opposite directions.
  • the invention has for its object to a powder-powered setting tool create, in which the sealing element seals the receiving chamber well and with a contact pressure is pressed against the first part, the propellant pressure corresponds.
  • the inventive design and arrangement of the annular sealing element enables pressing of the sealing element depending on the gas pressure against the first part.
  • the sealing element preferably has one Sealing section and at an end region of the sealing section on the setting direction a flange-like extension whose outer contour is larger than that largest clear width of the circular cutout.
  • One of the propellant gases acting on the contact surface of the sealing part can small amount between the outer wall of the sealing element and the Escape the outer wall of the annular cutout. So this small amount can be derived from escaping propellant gases from the inside of the setting tool, advantageously extends between the flange-like extension and one opposite to the counter surface set back against the setting direction a ventilation duct.
  • the sealing area is preferably from at least one lamellar seal formed in a lateral recess of the circular cutout is arranged.
  • the cartridge bearing as close as possible to the inner bore of the guide cylinder comes to rest is expediently the first part of a guide cylinder and the second part is formed by an impact floor of the setting tool.
  • the powder-powered setting tool shown in FIGS. I and 2 has a first part in the form of a guide cylinder 1 and a second part in the form of a butt plate 2. Both parts are arranged essentially coaxially to one another and parallel to Setting direction can be offset from each other.
  • the end area facing the impact floor 2 has a cartridge bearing 3, the clear width W1 increases towards the butt plate 2.
  • an inner bore 21 adjoins the cartridge bearing 3 in which a drive piston 22 is arranged axially displaceable.
  • the inner bore 21 is with the Cartridge bearing 3 via a connection bore 20 in connection.
  • a cartridge 4 is arranged in the cartridge store 3, which has a receiving part 5
  • a receiving part 5 For example, has a plurality of recording areas that the recording one serve, for example, powdered propellant charge. 1 is only one Recording area shown.
  • the receiving areas are by means of a cover part 6 lockable. Both the receiving part 5 and the cover part 6 are made of one thin-walled film formed
  • the fixing of the cartridge in the cartridge store 3 serves a butt plate 2 and an Butt plate 2 mounted sealing element 9.
  • the butt plate 2 has the one Cartridge bearing 3 side facing an annular cutout 7, the the end region of the butt plate 2 facing the cartridge bearing 3 into a central one cylindrical section and this cylindrical section at a distance surrounding circular outer section divided.
  • connecting channels 13 extending from a bottom of the annular Cutout 7 extend to a counter surface 14, which of the Cartridge bearing 3 facing end of the cylindrical portion is formed. Starting from the floor, the clear width of these connecting channels 13 increases to the counter surface 14 towards.
  • the cartridge bearing 3 has a largest clear width W1, that of the counter surface 14 in the radial direction at least from those between the connecting channels 13 lying areas is towered over.
  • an annular one Sealing element 9 arranged, which consists of a substantially hollow cylindrical sealing portion 10 and a flange-like extension 11 with the Outside diameter D1 is composed.
  • This flange-like extension 11 is in one arranged end direction of the sealing element 9 and has a stop surface 17 on the setting direction.
  • the depth T of the circular Section 7 is larger than the distance A between the flange-like extension 11 and an attack surface 16, which is of a free against the setting direction End of the sealing portion 10 is formed.
  • the sealing section 10 has, for example, a slightly curved outward Outside contour, which interacts with a sealing area 8.
  • Sealing area 8 is, for example, three annular disk-shaped Lamellar seals that are resilient in the radial direction. This Slats partially protrude into a circumferential groove in the outer wall of the annular cutout 7 and partially in the clear width of the annular Section 7.
  • the sealing portion of the annular sealing element and the sealing area of the butt plate in the area of the annular cutout can be with one another coordinated, interlocking thread profiles can be provided, which is a kind Form a labyrinth.
  • the annular sealing element 9 has on its end face pointing in the setting direction a sealing lug 12, which by a circumferential thin-walled Projection is formed.
  • the central cylindrical area of the butt plate 2 facing inner wall of this projection is on the same radius as that Inner wall of the annular sealing element 9.
  • the butt plate 2 has a circumferential on its end face pointing in the setting direction trained recess, which, starting from the outer contour of the annular Cutout 7, radially outwards, but not up to the outer contour of the Stossboden 2 extends.
  • a ventilation duct 15 opens into this depression.
  • the peripheral region of the flange-like extension 11 of the annular sealing element 9 is in connection with an elastic disk-shaped Membrane 19, which in turn is fixed on the setting direction end face of the butt plate 2 is connected.
  • the central cylindrical section protrudes with its in the setting direction Counter surface 14 the remaining part of the end face of the butt plate 2.
