INTERNAL COMBUSTION ENGINE WITH VARIABLE COMPRESSION RATIO
First Claim
1. Internal combustion engine, comprising:
- at least one cylinder with two oppositely directed reciprocatingly movable pistons in it, which are each connected via a piston rod with a corresponding arm, whereby each arm shows an opening in which a main shaft that connects the two arms is rotatably supported in bearings, which main shaft includes an angle with a centre line of each opening, andmeans for varying the compression ratio in the cylinder, characterised that the compression ratio variation means comprise a division in the main shaft, as well as drive means in order to move the parts formed by it of the main shaft apart from each other.

Abstract
An internal combustion engine has at least one cylinder, and a means for varying the compression ratio in the cylinder. The at least one cylinder has two oppositely directed reciprocatingly movable pistons in it, which are each connected via a piston rod with a corresponding arm, whereby each arm shows an opening in which a main shaft that connects the two arms is rotatably supported in bearings. The main shaft includes an angle with a centre line of each opening. The means for varying the compression ratio in the cylinder includes a division in the main shaft, as well as drive means in order to move the parts formed by it of the main shaft apart from each other.
