AXIAL INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; piston machines. SUBSTANCE: proposed engine has crankless mechanism converting reciprocating motion of piston into rotary motion of working shaft. Cylinders are arranged in star-like manner. Piston are connected by rods through roller supports on their ends with inner working edges of path of rotating disk rigidly secured on shaft. Pairs of opposite cylinders are uniformly spaced over disk circumference, cylinders of each pair being displaced relative to their common longitudinal geometrical axis to side opposite to working rotation of disk. EFFECT: simplified design of engine. 2 cl, 2 dwg
