Combustion engine has two rotary pistons each with cylindrical core and outer ring containing segment of smaller radius to define combustion chambers between housing and piston which can be connected and sealed from each other by slider

摘要

The combustion engine has two rotary pistons (2,3) mounted rotatable in a housing (4) and each having a cylindrical core and outer ring whose radius corresponds in areas to the inner radius of the housing and whose thickness corresponds in areas to the thickness of the core. In the outer ring is a segment with smaller radius and/or different thickness so that a combustion chamber is defined between each housing and piston and the combustion chambers are connectable together. They can be sealed from each other at least in areas through at least one slider (5,6) which can be moved by the rotary piston.
