OIL-DISTRIBUTING RING DIVIDED BY PARTITION IN AXIAL DIRECTION, AND PLANETARY REDUCTION GEAR CONTAINING SUCH RING Russian patent published in 2020 - IPC F01D25/18 F02C7/36 

FIELD: engine building.

SUBSTANCE: present invention relates to ring (35) intended for distribution of lubricant material in a turbine engine, wherein said ring has an axis around which an annular cavity is formed, open in radial direction to said axis and limited by sides of first and second walls (39a, 39b), wherein from said cavity extend first and second channels (43, 45) for supplying lubricant, which diverge to different elements to ensure their lubrication. In direction parallel to axis (X), annular cavity is divided into at least first and second annular parts, which are separated from each other by a substantially radial partition (38) and are interconnected, respectively, with first and second channels (43, 45). Annular cavity (37) is configured to allow lubricant to flow in location of inner partition (38) parallel to said axis from first part of cavity into second part of cavity and vice versa without any flow through first wall and second wall. Invention also relates to an oil supply device comprising such a ring and a method of operation thereof, as well as to a planetary gear, containing such device, positive pressure turbojet engine and turbine engine.

EFFECT: achieved technical result consists in preliminary distribution of lubricant in parts of cavity and balance of pressure in them with provision, as a result, efficient distribution of lubricant and regulation of said distribution.
