LUBRICATING COMPOSITION FOR HYDRAULIC SYSTEMS OF AGRICULTURAL MACHINERY Russian patent published in 2021 - IPC C10M169/04 C10M101/00 C10M155/02 C10M137/10 C10N30/06 C10N40/08 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the composition of lubricants used in hydraulic systems of agricultural machinery. A lubricating composition for hydraulic systems of agricultural machinery containing rapeseed oil, characterized in that it additionally contains DF-11 additive as an anti-wear and antioxidant additive, EFO additive as an antiscuffing pressure additive, fine graphite as an antifriction additive, PMS-200A additive as an anti-foam additive, with the following ratio of components, wt. %: DF-11 3…4; EFO 3…4; fine graphite 4…5, PMS-200A 0.003…0.004, rapeseed oil up to 100.

EFFECT: increased reliability by reducing the wear of friction pairs of aggregates of agricultural hydraulic systems and improving the environmental performance of their work.
