Rotary piston internal combustion engine has rotary piston oval in cross-section rotatably located in chamber in housing and having face-side end plates, with oval longitudinal bore corresponding to its cross-sectional contour

摘要

The rotary piston (5) in an internal combustion engine (1) has an oval cross-section and is rotatably located in a chamber (4) in a housing (2,3,31). It has face-side plates (6,7) and drives a driven shaft (18). The chamber forms two work chambers with the rotary piston, which with the continuous movement of the piston are enlarged and diminished. The piston has an oval longitudinal bore corresponding to its cross-sectional contour, the longer cross axis of which runs in the direction of the shorter cross axis of the cross-sectional contour. An oval hollow wheel (24) is incorporated, which meshes with at least one pinion (22,23) on the driven shaft.
