ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; rotary-piston internal combustion engines. SUBSTANCE: engine has housing with ring chamber closed from end faces by inner and outer walls. Chamber accommodates coaxial outer and inner working shafts with rotor pistons installed symmetrically in pairs to form working spaces in rings chamber. End face walls are rigidly connected with one pair of pistons, and inner wall is additionally connected with inner working shaft. Toothed sectors 18-21 and planet pinions 22-25 are installed symmetrically in pairs on outer working shaft and on outer side on inner and face wall. Planet pinions 22, 24 on outer working shaft come into meshing with toothed sectors 19, 21 on outer side of inner end face wall, and planet pinions 23, 25 on outer side on inner end face wall come into meshing with toothed sectors 18, 20 on outer shaft. Toothed sector 26 is fixed in housing coaxially with working shafts for engagement with planet pinions 22, 25. Working shafts are connected to inlet links of summing up mechanism. EFFECT: equalized speeds of output shaft. 2 cl, 9 dwg
