Patent ID: 10737201

Abstract:
A filter system (100) has at least one filter element (10), a filter housing (108) having at least one first housing part and one second housing part, in particular a lid (110), as well as a coupling device (50). The coupling device (50) thereby has at least one first coupling part (60) and at least one second coupling part (70) that corresponds to it for removable coupling of the at least one filter element (10) to the second housing part (110). The first coupling part (60) has one or a plurality of first latching means (62) and control surfaces (64). The second coupling part (70) has one or a plurality of second latching means (72) that can be brought into operative connection with the one or a plurality of first latching means (62) and control surfaces (64). At least the first and the second latching means (62, 72) can be brought into functional connection when joined, and the control surfaces (64) and the second latching means (72) can be brought into operative connection when first and second housing parts (110) are released. The second latching means (72) each have three bevels (76, 77, 79), at least two of which work together with the control surfaces (64) to release the second housing part (110) from the filter element (10) upon a relative rotation of the filter element (10) around the longitudinal axis (L) counter to the second housing part (110).
