HYDRAULIC MOUNTING SYSTEM OF FARM TRACTOR Russian patent published in 2011 - IPC F15B21/04 F15B19/00 

FIELD: machine building.

SUBSTANCE: hydraulic mounting system consists of hydraulic tank, of suction hydraulic line, of oil gear pump, of two pressure hydraulic lines protected with safety valve from excessive pressure rise in system, of high pressure hydro-line, of hydraulic valve with two working pipe bends and drain line, and of power regulator with two pipe bends and drain line. The hydro-system is equipped with a hydro-line of low pressure whereon there is arranged a centrifugal separator. An output of the separator is connected to the purified oil drain line having a working pipe bend. On the pipe bend there are positioned an electric-spark device of automatic doping oil with additive and an electro-magnetic valve communicating the working pipe bend with the hydraulic tank and opening at transmission of a signal through the control line from a pressure gauge on the high pressure line. The system is equipped with a flow dividing valve, an input of which is communicated with the pressure line, the first output is connected with the high pressure hydraulic line, and the second output is connected with the hydro-line of low pressure, wherein the flow dividing valve maintains constant oil pressure.

EFFECT: upgraded quality of purification of hydraulic fluid and maintaining rated resource of additives.
