Abstract: Filter element for filtering a liquid, wherein the filter element (1) is designed to be installed in a housing (31) with a cover (32), the filter element (1) having a first end cap (2) facing the cover (32), a second end cap (3), and a filtering medium (4) with a hollow interior (5), wherein the filter medium (4) is arranged between the first end cap (2) and the second end cap (3), wherein the first end cap (2) has a sealing means (6) over the outer circumference of the end cap, wherein the first end cap (2) has a first opening (7), wherein an elastically reversible compensation element (8) can be arranged in the interior (5), said compensation element in a position of a cover-side exterior (9) of the filter element (1) arranged in the interior (5) protrudes into the interior (5) through the first opening (7) and seals the interior (5) in a fluid-tight manner against a passage of liquid from the interior (5) into the cover-side exterior (9) through the first opening (7), wherein the sealing means (6) is desig

Abstract: The invention relates to a filter element (I) for filtering a liquid and for a flow of the liquid from an unfiltered side (50) to a clean side (52). The filter element (I) has a first end cap (2), a second end cap (3), and a filter medium (4) with a hollow interior (5). The filter medium (4) is arranged between the first end cap (2) and the second end cap (2) along an axial direction (A) wherein the first end cap (2) has a first opening (6) for a flow of the liquid, and a grip guard (7) is arranged in the first opening (6), said grip guard being configured to prevent a finger from penetrating into the interior (5) through the first opening (6).

Abstract: The invention relates to a component for a liquid filter (30) which has a housing (31), said component (100) having:—a cover (32) for installing on the housing (31);—a filter element (1) comprising—first end cap (2) facing the cover (32),—a second end cap (3) facing away from the cover (32), and—a filter medium (4) which is arranged between the first end cap (2) and the second end cap (3) along an axial direction (A) and which comprises a hollow interior (5); and—an elastically reversible compensation element (8); wherein the cover (32) has a cover lower face (42) facing the first end cap (2), and the first end cap (2) has an upper face (24) facing the cover (32). The cover (32), the filter element (1), and the compensation element (8) are captively coupled together.

Abstract: The invention relates to a heating device (6) for a tank (2) of an exhaust gas aftertreatment agent system, having a carrier (7) and having a plurality of heating elements (10) arranged on the carrier (7). According to the invention, the carrier (7) has a plurality of carrying elements (8), which are connected to one another in an articulated manner, and at least one spring element (13), which applies a spring force to at least two of the carrying elements (8). The carrier (7) is thus formed to be flexible or deformable overall, wherein the carrier is forced into a final shape by the spring element.
