Document Type and Number:
Japanese Patent JPH0819856
Kind Code:
B2
Abstract:
A rotary piston internal combustion engine having a structure wherein a curve determining a side surface profile of a cylindrical hollow of a housing is set to a synthetic trochoid or parallel synthetic trochoid as a locus of a creation point of a peritrochoid obtained by fixing a base circle of the peritrochoid to an eccentric arm of a hypotrochoid so that the base circle of the peritrochoid is concentric with a rotating circle of the hypotrichoid and by fixing the eccentric arm of the peritrochoid to a creation arm of the hypotrochoid so that the center of the rotating circle of the peritrochoid becomes the creation point of the hypotrichoid, and wherein a curve determining a profile of a section of the rotary piston becomes an inner envelope line of a group of curves of the synthetic trochoid or an inner envelope line of a group of curves of the parallel synthetic trochoid. The rotary piston revolves round the origin O while performing a planetary motion with a point Q being the center, with the rotation of the rotary piston. Accordingly, a displacement of an operation chamber can be changed with the rotation of the rotary piston.
