Patent ID: 7546842

Claim:
Oil flushing equipment for machinery with rotating parts ( 40 ) which includes a tank ( 1 ), a motor-pump unit ( 9 ), and oil filtration measures connected to a pipe unit for oil circulation, comprising: valves ( 7 , 20 ) included in the pipes which allow the differentiation of a first circuit (A) to fill the machinery ( 40 ) with oil from the tank ( 1 ) through pressure filters ( 19 ), a second circuit (B) for re-circulation of oil through the machinery ( 40 ), through the pressure filters ( 19 ) and a vacuum filter ( 22 ), a third circuit (C) to empty the machinery ( 40 ) of oil and take it to the tank ( 1 ) passing through the pressure filters ( 19 ) and the vacuum filter ( 22 ), and a fourth circuit (D) to clean the oil in the tank ( 1 ) re-circulating it through the pressure filters ( 19 ), wherein the first, second, third, and fourth circuits (A, B, C, D) share the motor pump unit ( 9 ) and two pressure filters ( 19 ) placed in serial, and the vacuum filter ( 22 ), included in the second and third circuits (B,C), is situated between the machine ( 40 ) and the motor pump unit ( 9 ).
