ROTOR AXIAL ENGINE AND ENGINE LUBRICATION SYSTEM Russian patent published in 2019 - IPC F01C1/344 F01C1/356 F02B55/02 F01C21/04 

FIELD: engines.

SUBSTANCE: group of inventions relates to rotary internal combustion engines. Essence of the inventions consists in the fact that the engine comprises a housing in which there is a wave-like annular channel for the working medium and a rotor is installed, the peripheral part of which is in the channel. Support bearing is installed on end sections of the rotor entering the housing. In the peripheral part of the rotor there are slots, in each of which there are two adjoining disk pistons with the possibility of sliding relative to each other in the tangential plane and displacement during rotation of the rotor along the wavy channel. At contact, disc pistons have common shape of flattened cylinder with tangential slots located diametrically opposite, and disk end parts, which are located on both sides of slots. In the recesses on the disc part circumference the spring rings are installed with the possibility of turning along the perimeter of the disk parts. Rotor slots have shape corresponding to section of two adjoining disk pistons in diametral plane perpendicular to direction of tangential slots. Engine is equipped with lubrication system of support bearing and sealing elements of disk pistons, which contains oil channel in rotor axis, connected through hole in rotor with annular groove, to which radial channels in rotor are connected, which are suitable to each slot and in end are connected to annular cavity for collection oil equipped with outlet channel. Channels for oil supply to the thrust bearing are connected to the radial channels in the peripheral part of the rotor. Disk pistons have channels extending to sealing elements from axial semicircular grooves of disk pistons, which are made with possibility of formation of through lubrication channel of engine elements at periodic coincidence of axial grooves with radial channels in rotor. Input of oil channel in axis of rotor through fine filter is connected to outlet oil line of supply oil tank, and annular cavity through outlet channel is connected to oil cooling system, which is closed to supply oil tank.

EFFECT: technical result consists in improvement of engine reliability and increase in its service life.
