ABSTRACT
The ball piston engine (wolf hart engine)is an rotary engine (internal combustion engine) that uses two inter winded rotors instead of reciprocating piston. A spherical piston rotates in combination with a spherical housing, whereby the rotational axis inclined towards each other slightly. In this way “strokes “ are created within the rotational system generating periodic volumetric changes in the working chambers adjacent to the dividing wall.
