Claims

[Scope of utility model registration request]

A full-flow filter is disposed in a pressure passage that supplies pressurized oil to each lubricating section, a bypass filter is disposed in a branch passage that branches from the pressure passage and leads to the oil pan, and a bypass filter is disposed downstream of the bypass filter. In an engine oil filtration device, the engine oil filtration device is provided with a throttle on the side for restricting the flow rate of oil passing through, the above-mentioned pressure-feeding passage, the mounting part of the full-flow complete filter in which the pressure-feeding passage is opened, the above-mentioned branch passage, and the branch passage is opened. A bracket is provided in which a branch passageway upstream from the attachment part of the bypass filter is provided with a passage cross-sectional area larger than and less than the passage cross-sectional area of the throttle (in both cases, when the oil temperature is low, the pressure-feeding passage 1. An oil filtration device for an engine, characterized in that a throttle is provided to form a passage cross-sectional area smaller than the cross-sectional area of the bracket, and the full-flow filter and bypass filter are attached to the bracket via a sealing member.
