Definitions

  • the seal protrudes on both sides over the final plane of the groove, so that penetration of water into the gap in both axial directions of movement of the bottom is avoided.
  • the seal may in particular be formed symmetrically.
  • an elastic support member is arranged under the sealing ring.
  • a support member may in particular be a circumferential ring inserted into the groove from an elastic material, for example an elastomer or a spring plate.
  • the support member may consist of several individual elastic members instead of a circumferential ring.
  • a preferred embodiment of the tacker has a housing with which the combustion chamber wall is rigidly connected.
  • the floor then constitutes a moving part in the tacker.
  • An alternative embodiment of the tacker has a housing to which the floor is rigidly connected.
  • the combustion chamber wall is then in the tacker a moving part.
  • the bottom is so far adjustable relative to the combustion chamber wall that forms an inlet and / or outlet opening of the combustion chamber for air and / or fuel between the bottom and the combustion chamber wall.
  • the bottom and the combustion chamber wall form an inlet and / or outlet valve of the combustion chamber.
  • the tacker off Fig. 1 is a hand-held device, comprising a housing 19 and a combustion chamber 1 with a partially cylindrical combustion chamber wall 2, which is rigidly connected to the housing 19. Adjacent to the combustion chamber 1 is a cylinder 3 with a drive piston 4 guided therein.
  • a safety mechanism of the device comprises annensetzhülse 5, which is placed on a workpiece (not shown) and is pressed against the pressure of a spring. Only in this state, a driving operation can be triggered by igniting a fuel gas in the combustion chamber.
  • a swirl plate 6 is also arranged, which can be moved by the combustion chamber 1 before ignition.
  • the seal 8 is formed as a set of two sealing rings 10, 11 lying directly one above the other in the axial direction. Both seal rings 10, 11 are received in the same groove 12 on an outer peripheral wall 7 a of the bottom 7.
  • the sealing rings 10, 11 are made of a hard material, in the present case a steel.
  • the sealing rings 10, 11 each have an open shock 13 to be inserted into the groove 12.
  • the impact allows a defined pressing of the sealing rings to the combustion chamber wall.
  • an elastic support member 14 is disposed in the groove below the sealing rings. When using sealing rings 10, 11, the support member 14 is pressed in the radial direction and resiliently acted upon by a force.
  • the joints 13 of the sealing rings 10, 11 are circumferentially offset from each other. In the illustration after Fig. 3 is the shock 13 of the front seal ring 11 in the sectional plane and is therefore visible.
  • the sealing rings 10, 11 in the present case have a respective L-shaped cross section and are arranged mirror-symmetrically to a median plane of the groove.
  • the sealing rings 10, 11 may be formed as the same components.
  • the respective one leg of the L-shaped cross-section engages in the groove 12 a.
  • the respective other leg extends in the axial direction in the gap 15 between the peripheral wall 7a of the bottom 7 and the combustion chamber wall 2.
  • a respective front surface 10a, 11a of the sealing rings 10, 11 protrudes in front of a final plane E1, E2 of the groove in the axial direction 12.
  • the front surface 10a, 11a in the axial direction also protrudes in front of a respective termination level A1, A2 of the bottom 2.
  • a respective radially inner end of the front surfaces 10a, 11a has a sharp-edged end 10b, 11b in the form of an edge an angle of 90 °.
  • the edge lies in each case before the termination plane A1, A2 of the bottom 2.
  • a radius of curvature of the edge is preferably less than 0.5 mm, in particular less than 0.2 mm.
  • a recess 16 is provided on the bottom 7.
  • the recess 16 is formed as an annular space which remains between the bottom 7 and a stop ring 17. With the combustion chamber fully open, the bottom 7 is supported on the stop ring 17. Through openings 18, the stripped water can also flow past the stop ring 17 in other housing areas.
