Wankel engine rotor

摘要

A rotor (24; 124; 224) for a Wankel engine (10) including a plurality of ribs (74; 76) extending from a bearing support (20) to each one of the flanks (72), the plurality of ribs (74; 76) including, for each flank (72), first (74) and second (76) ribs connected to the flank (72) between the recess (38) and a respective one of the apex portions (30). The first and second ribs (74; 76) are curved along at least a portion thereof. A method of reducing pinching of apex seals (52) in a rotor of a Wankel engine (10) is also discussed.
