Document Type and Number:
Japanese Patent JP3008252
Kind Code:
B2
Abstract:
A rotary piston engine (20) is shown which includes a housing (22) having a cylindrical working chamber with inlet (56) and exhaust (54) ports. First and second piston assemblies (30 and 32) each of which includes at least one pair of diametrically opposed pistons (30A and 30B, and 32A and 32B) are located in the working chamber. Backstopping clutches (44 and 46) limit rotation of the piston assemblies (30 and 32) to one direction (42). Piston assemblies (30 and 32) are connected to the engine output shaft through a differential (78) and non-circular gear sets (74 and 76), each of which gear sets includes a tear-drop shaped gear (74A and 76A) and heart shaped gear (74B and 76B). When the cusp of the tear-drop shaped gear engages the recess in the heart shaped gear, the tear-drop shaped gear is prevented from rotating. The piston assemblies rotate intermittently whereby pistons of the stopped assembly are trailing pistons during portions of the power and intake phases of engine operation. In one embodiment, the tear-drop shaped gear include teeth in the form of rollers (132).
