ENGINE WITH SWING PISTONS AND SEALING SYSTEM Russian patent published in 2012 - IPC F01C9/00 F01C19/02 F01C19/12 F01C21/04 

FIELD: engines and pumps.

SUBSTANCE: pistons are coupled with rotary swing shaft. Said shaft runs about rotational axis. Pistons swing about swing axis perpendicular to rotational axis. Guide elements are arranged on pistons. Guide elements fit in, at least, one guide groove in housing. Cantilever elements of two pistons are arranged to make four intermediate spaces. Each of said two intermediate spaces makes working chamber while each of the other two intermediate spaces makes forechamber. Engine comprises zones of clearances between its parts that displace relative to each other in piston rotation and swinging. Sealing system incorporates sealing elements made up of seal strips or rings to cover gap zones and comprises sealing element lubricator. Sealing elements are arranged nearby swing piston edges relative to guide elements, adequate guide groove, forechambers and working chambers to cover zone of gaps so that pressure drop in said chambers is ruled out as well as ingress of lubricant therein.

EFFECT: production of engine with swing pistons with sealing system.
