Abstract

A cleaning device for cleaning lubricating oil which circulates in a lubricating oil circuit has an intake to be connected with the lubricating oil circuit, through which a part quantity of the lubricating oil circulating in the lubricating oil circuit is to be fed to the cleaning and a return to be connected with the lubricating oil circuit for the returning of the cleaned lubricating oil into the lubricating oil circuit. The device includes a closed cleaning circuit in which the intake terminates, a feed device for the circulating a mixture of a circulating oil contained in the cleaning circuit and the lubricating oil to be cleaned fed to the cleaning circuit through the intake, and at least one cross-flow filter arranged downstream of the feed device seen in the feed direction, which is provided with at least one filter membrane past which flows the mixture of circulating oil and lubricating oil to be cleaned, wherein a part of the mixture flows through the filter membrane into a filtrate chamber connected with the return.
