A plate-type filter lubricating oil or the like. The filter includes a cylindrical, rotatable filter element which is to be cleaned in closed condition by flow reversal along a portion of the filter surface. During the normal operation the entire filter surface is to be effectively available. The device includes a rinsing channel wall having a U-shaped profile, one leg of which constantly engages against the filter element and consequently serves as a wiper body during rotation of the element. To clean the filter element, both legs are pressed against the element, so that a rinsing channel results which communicates with a rinse-out opening and represents a back or return flow through the filter surface. A combination of two such filters provides an advantageous device for machines that are continuously operated.
