  • Publication number: 20210069620
    Abstract: An intermediate cover of a filter housing of a filter for purifying liquids can be mounted in the filter housing for separating a filter receiving space for a filter insert from a centrifuge receiving space for a centrifuge separator by a rotary and/or insertion movement relative to an imaginary axis. The intermediate cover is provided with a portion of at least one clean fluid channel forming a fluidic connection between a clean fluid side of the filter insert and a fluid outlet of the filter housing for a purified clean fluid. The filter insert has a connecting device arranged at an axial end face and connectable to the intermediate cover. An outlet opening for purified clean fluid is arranged at the axial end face and corresponds with an inlet opening of the clean fluid channel of the intermediate cover. The outlet opening at least partially forms the connecting device.

  • Publication number: 20210008472
    Abstract: A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.
