FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to rotary engines with rocking working members. Proposed four-stroke engine consists of two coaxial sections. According to invention, timing gear is made in form of inner tube rotating inside rocking hollow shaft. Time of one revolution of rotating inner tube is four times as great as one full turn of rocking hollow shaft with return to initial position. End face seals are provided with grooves for U-shaped section sealing members with elastic pressure tape inside, and channels for delivering cooling medium and lubricant are arranged inside hollow shaft and rocking pistons.
EFFECT: simplified design of engine.
