ROTARY-VANE INTERNAL COMBUSTION ENGINE (VERSIONS), VANE ROCKING MECHANISM, UNIT OF VANE SEALING MEMBERS AND VANE ROCKING MECHANISM BEARING SUPPORT Russian patent published in 2004 - IPC

FIELD: power engineering.

SUBSTANCE: invention can be used in engines operating in vehicles and stationary power plants. According to invention proposed engine has two nonuniformly rotating vane sets arranged inside cylindrical part of housing and gas space and gas channel connecting space with working chamber expansion zone at end of expansion through outlet port made in housing. Support gear is installed in vane rocking mechanism housing for movement and is coupled with mechanism to adjust angle of gear fastening relative to housing in plane square to axes of output shaft. Clearances between inner surface of vane slots and plates in longitudinal sealing unit are filled with elastoplastic material. In radial sealing unit contacting ring surfaces of ring and side cover are made conical, displace between conical contacting surface and inner end face surface of side cover is made decreasing to inner cylindrical surface of housing. Each pocket in bearing support unit of vane rocking mechanism communicates with device for pressure feeding of lubricant made in pin of central channel and provided with check valve and with closed system of hydraulic channels by means of peripheral channel made in pin. Pockets located at one and the same side of plane of location of longitudinal seals relative to direction of rotation of vanes are in communication with one closed system of channels and pockets arranged at other side from said plane, are in communication with other closed system of channels.

EFFECT: increased power output, improved reliability, economy and operating and ecological characteristics of engines.
