FIELD: engines and pumps.
SUBSTANCE: GTD oil purification system additionally comprises filters arranged in separate casings and having no bypass valves that have replaceable filter elements and are connected to GTD oil purification system. Bypass valves incorporated with lubrication system of friction units represent separate elements arranged independent of the casing of GG, ST and ACS filters. In compliance with one version, bypass valve of the aircraft GTE standard oil system is used for GG filter. In compliance with the other version of the GTD oil purification system, bypass valves representing separate elements and fitted independent of filter casings are incorporated only with GG and ST lubrication systems. Hence, bypass valve in ACS lubrication system is not used.
EFFECT: simplified design of filters GG, ST and ACS, reduced maintenance costs, expanded performances of standard oil system of GTE.
