PISTON MACHINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used as internal combustion engine. Proposed machine with housing 25 has at least two cylinders 3, 4; 5, 6 with intake or exhaust holes opened and closed by controllable valves. Piston 7,8,9,10 reciprocates in each cylinder 3, 4, 5, 6. Transfer mechanism to convert movement of pistons 7, 8, 9, 10 into rotary motion of shaft 17 or vice versa is provided. Said mechanism contains turnable lever 13, 18 turning around turning axle 14, 20 arranged in middle and installed in housing 25. Lever is furnished with rotating rollers 15, 19 on both end sections whose axes of rotation are arranged square to axis of turning axle 14, 20. Rollers 15, 19 roll over race 16 rigidly connected with shaft 17 arranged so that it passes between two rollers 15, 19. Race is provided with projections and cavities to provide contact of rollers 15, 19 with race. Both end sections of lever 13, 18 are hinge-coupled with connecting rod 12 connected with corresponding piston 7, 8, 9,10.

EFFECT: provision of minimum friction and wear.
