  • An inventively designed cylinder 11, 12 with positive control for two pistons, the outer sleeve piston 2 and the inner piston 3, has a positive guidance as in FIG. 1 shown on.
  • the sleeve piston 2 has left on the circumference extending in the axial direction of the piston axial guide track 23 for axial positive guidance in the vertical direction, so that the sleeve piston 2 does not rotate.
  • Only the inner piston 3 is connected via a connecting rod 91 (not shown) with the crankshaft 9 (not shown). It will open Fig. 6 directed.
  • the sleeve piston 2 has a circumferentially varying distance to the combustion chamber slide track 24, and a standing with the crankshaft 9 in connection ring gear 4, which is rotatably mounted in the cylinder wall 11, 12 between the cylinders 11 and 12.

This axial deflection from the locking plane corresponds to the stroke of the sleeve piston 2.
  • the axial guidance of the sleeve piston 2 so that it does not rotate, can be realized by a formed along the outer wall of the sleeve piston 2 guide track 23, which is in engagement with a cam roller 6 mounted in the cylinder 11, 12.
  • An effective reversal is generally possible, however, a weakening of the cylinder surface is not preferred by a longer path, so it is advisable to support the cam roller 6 on the cylinder wall of the cylinder 11,12 and provide the guide track 23 in the sleeve piston 2.
  • This cam roller 6 then engages in the formed on the sleeve piston jacket surface groove, the guideway 23, a.

  • the ring gear 4 is driven by a pinion 5 and carries on its inside another guide roller, the cam roller 7, the is moved through the slide track 24 therethrough, whereby it stops the lifting movement of the sleeve piston 2 in the flat portion and moves in the inclined portions closer to the piston end face.
  • the crankshaft 9 For the drive of the pinion 5 provides a mechanically coupled to the crankshaft 9 means so that the crankshaft 9 and ring gear 4 are coupled together for rotation. It is particularly advantageous that the teeth of pinion 5 is carried out with the ring gear 4 for rotating the ring gear 4 at half crankshaft speed.
  • the ring gear 4 thus rotates at half the crankshaft speed, so as to make one half of the sleeve piston circumference with its cam roller 7 in the slide track 24 to a locking path.
  • the sleeve piston 2 is supported on the inner piston 3, while during the operation of the sleeve piston 2 in the expansion of the fuel gases also acts on the inner piston, ie on both pistons 2, 3 together.
  • the Fig. 2 shows a side sectional view of the cylinder 11, 12 with the ring gear 4, which is rotatably formed between the cylinder sections, and the pinion 5, which drives the ring gear 4.
