Definitions

  • a drive element and a piston unit are arranged axially parallel, wherein the drive element axially overlaps at least partially with a longitudinal extension of the piston unit, and wherein the drive unit is arranged approximately centrally in an axial extension of the piston unit and its longitudinal axis is arranged transversely to the piston longitudinal axis.
  • the drive element is arranged offset laterally relative to the piston unit, wherein a drive path is advantageously shortened by the axial overlap.
  • the length of the drive element is taken out of the determining Trekette for the length of the device. The length of the device is conveniently shortened significantly. This leads to a favorable compact and ergonomic design of the device. Further advantages are an ideal weight distribution and better handling of the device.
  • the eccentric pin 22 is encompassed by a connecting rod eye, not shown, of the connecting rod 16.
  • the linear lifting movement of the connecting rod 16 is transmitted via a pivot pin 17 to a drive rod 19.
  • the drive rod 19 is arranged parallel to the connecting rod 16 and is guided axially.
  • About the drive rod 19 is the as
  • Fig. 4 corresponds substantially to the representation in Fig. 1.
  • the piston unit 13 comprises a cylindrical piston.
