Problems solved by technology

If the removal tool is locked only behind the front opening viewed with respect to the insertion direction, there is the risk that when the removal tool is pulled out, the possibly fluid-soaked filter element is torn apart and in this way a part of the filter insert remains inserted in the housing

Embodiment Construction

[0055] Figure 1a A prior art removal tool 60 is shown. The removal tool 60 is designed in one piece in the form of an ice cream stick or spatula. In other words, the removal tool has a flat, elongated extension. At the front, distal end 61 , the removal tool 60 has a first hook 63 and a second hook 64 , which are designed in the form of two fork tines. A similar structure also exists at the distal second end 62 of the removal tool 60 . The removal tool 60 has a recess in its central section between the first end 61 and the second end 62 so that it is as flexible as possible and bendable.

[0056] Figure 1bThe prior art removal tool 60 is shown during insertion into the filter insert 70 along the insertion direction 80 . The filter insert 70 has a hollow cylindrical configuration and extends along the longitudinal axis A. As shown in FIG. The filter insert 70 comprises a first end cap 71 with a first opening 73 and a second end cap 72 with a second opening 74 . The fil...

Abstract

The invention relates to a removal tool (1) for a filter insert (70) of a liquid filter (90). The removal tool (1) comprises a first arm (10), which extends along a first axis (A1) and a second arm (20), which extends along a second axis (A2). The first arm (10) has a first hook (11), which protrudes substantially transverse to the first axis (A1) of the first arm (10). The second arm (20) has a second hook (21), which protrudes substantially transverse to the second axis (A2) of the second arm (20). The first arm (10) and the second arm (20) are connected to each other by a rotating joint (30).

Description

technical field [0001] The invention relates to a removal tool for a filter insert of a fluid filter. The invention also relates to a method for removing a filter insert of a fluid filter. Background technique [0002] Fluid filters are known from the prior art. Fluid filters of this type can be used, for example, in the automotive sector to clean particles and water from fuel. The further fluid filter is designed to purify the urea solution which is used in the DENOX system, that is to say for the reduction of nitrogen oxides. Fluid filters of this type generally consist of a housing, an inlet for the fluid and an outlet for the cleaned fluid. A replaceable filter insert can be arranged in the housing of the fluid filter. The filter insert can, for example, be formed by a filter element which is fastened between a first end cap and a second end cap. The first end cap may have a first opening and the second end cap may have a second opening. [0003] In order to contin...
