Definitions

  • the invention relates to a sealing or perforating apparatus. or driving or driving any element into a material receiver, of the nailer, stapler or hammer type, with gas operation.
  • a piston is movably mounted in a cylinder to be propelled there, by the explosion of a mixture of air and a gas fuel injected from a cartridge into a combustion, and to drive an element, for example fixing (a nail or a tampon), or other ankle.
  • a cage which, during support and by means of a probe which can be a movable tampon guide, pushes back a chamber sleeve until it stops against the cylinder head which carries the spark plug intended to cause the explosion, in order to close the combustion chamber thus formed by this sleeve, cylinder head and piston head.
  • the cage and the sleeve can be linked to each other by screwing.
  • the back of the cage is carried out against the action of a return spring, to return the device to its position opening, also pressing against the piston cylinder.
  • the device In the open position, after firing, the device is purged and cooled by suction of fresh air from the rear and, when it is provided in the room a fan, letting it run to speed up the purge.
  • a flexible annular membrane isolating the annular space, between the sleeve chamber and the housing of the appliance, of the combustion chamber.
  • the invention of the present application aims to eliminate this disadvantage.
  • the invention relates to an apparatus comprising a housing, a cylinder head, a chamber sleeve, arranged for, when putting in support of the device, form with the cylinder head a combustion chamber, a cylinder and a piston arranged to be propelled by the explosion of a mixture of air and gas in the room and cause an element, the part rear of the housing being arranged to form a fresh air intake of cooling of the apparatus and purging of the chamber and means being mounted on the chamber sleeve for, when opening the device, isolate the space between the front part of the chamber sleeve and the housing, of the combustion chamber, characterized in that it is provided means for channeling fresh cooling and purging air directly to the bedroom.
  • the channeling means of the apparatus of the invention eliminate any unnecessary and disruptive space.
  • the channeling means comprise a annular bellows extending between the insulation means and the cylinder head, advantageously connected to the insulation means and fixed to the cylinder head, better again, in one piece with the insulation means and fixed to a portion annular device of the breech.
  • the isolation means may include a flexible annular membrane.
  • channeling means can also be fitted directly on the chamber sleeve and ensure the insulation function of the combustion chamber.
  • the device At the front of a cylinder head 1, carrying a spark plug (not shown) and a motor fan 2, the grip handle and for actuating the appliance, a gas cartridge and a charger elements (here anchoring), the device comprises, in a housing 3, a chamber sleeve 4, a cylinder 5, with a front portion 6 of reduced section, a chamber closure cage 7 and a tip guide 8.
  • the tip guide 8, moreover conventional, is integral in translation of the cage, here by screw, cage including a semi-tubular front portion 9 wraps around the back of the tip guide.
  • the front portion 9 of the cage 7 is extended, towards the rear, by two lateral arms 10, 11.
  • the two arms 10, 11 of the cage extend along the cylinder 5, outside, up to the front part 12 of the chamber sleeve 4.
  • Springs 13 for returning the chamber to the open position extend over the outer wall 14 of the cylinder, linked to the cage 7 and in abutment against an annular shoulder 15 of the cylinder.
  • a seal 22 intended, in the closed position, to be secured with the sleeve chamber 4 the front seal of the combustion chamber 17.
  • a seal 23 intended, in the closed position, to be secured with the part rear 16 of the chamber sleeve 4 the rear seal of the chamber combustion 17.
  • a flexible annular membrane 24, here made of elastomer, is slipped by its internal periphery in an annular groove 25 formed in a plane transverse, perpendicular to the axis 26 of the device, in the rear part 16 of the chamber sleeve 4.
  • the membrane 24 allows, when opening of the device ( Figure 2), to isolate the chamber 17 from the space 32 existing between the front part 27 of the chamber sleeve 4 and the housing 3, so avoid, during the purge, the recycling of the burnt gases.
  • the rear part 28 of the housing 3 is pierced with gills 29 suction, intake, fresh air, for cooling the appliance and venting the combustion chamber 17.
  • the bellows 30 is used, at the opening of the device (FIG. 2), to channel the fresh air drawn in through the vents 29 directly to the combustion 17, without any notable disturbance of the flow 33.
  • the air sucked passes around the cylinder head 1 and, through the passage formed between the cylinder head edge 31 and the rear part 16 of the chamber sleeve 4, arrives directly in room 17.
