Abstract (en)
[origin: EP2476870A1] The device has several oil filter units (11,17) arranged in oil flow paths from oil reservoir (3) to main oil passage. A filter unit switching unit (14) selectively switches filter units so that selected filter units function as active filter units and remaining filter units function as passive filter units. A switching unit (7) in flow path from oil reservoir to filter units selectively switches filter units so that pressure oil from pressure oil flow path (8) is released, and oil accumulated in a region of passive filter unit is drained to drain channel (20) by suction device (21).
