Abstract:
An oscillating-piston engine, comprising:a housing having a circular inner wall and a central housing axis;several pistons configured as two-armed levers, each two adjacent pistons of said pistons being in rolling engagement with one another, wherein said pistons are movable together in a revolution direction;several piston axes parallel to said housing axis, each of said pistons arranged pivotably about one of said piston axes, respectively, wherein said piston axes revolve about said housing axis on a circular track concentric with said inner wall of said housing;a cam piece arranged centrally in said housing, said cam piece having an outer contour;said pistons having running surfaces being configured on sides of said pistons facing said cam piece, wherein said running surfaces, as said pistons revolve in said housing, are guided in constant contact with said outer contour in such a way that the pivoting movements of said pistons during revolution are controlled, regardless of the revolution speed, exclusively by the guidance of said pistons along said outer contour of said cam piece in coaction with the rolling engagement.
