Title:

OIL DEGRADATION PREVENTION DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/168648

Kind Code:

A1

Abstract:

Provided is an oil degradation prevention device with which the trapping effect with respect to oil degradation components can be improved and with which the oil passage resistance can be reduced, thereby suppressing a rise in pressure loss. This oil degradation prevention device (1) is equipped with: a filter unit (3) equipped with a filter material (10) that filters oil; and a degradation suppression unit (4) equipped with a powder-like degradation-suppressing agent (17) that suppresses oil degradation. The degradation suppression unit contains a mesoporous inorganic material, and of the oil fed from an oil storage unit (9), the oil filtered by the filter unit is fed to parts which are to be lubricated, and the oil in which degradation has been suppressed by the degradation suppression unit is returned to the oil storage unit or is fed to the parts to be lubricated.
