Abstract

The filter element (10) has an opening (20) for passing a fluid to be filtered through the filter element, where the opening is provided with a closure device (26). The closure device closes the opening in the disassembled condition of the filter element. The closure device is freely designed in the installed condition of the filter element. The closure device is designed with a breakable wall. An independent claim is also included for a filter with a force that is required for mounting the filter element in the filter.

Description

technical field [0001] The invention relates to a filter element having at least one opening through which a fluid to be filtered passes. The invention also relates to a filter with such a filter element. Background technique [0002] Filters of the aforementioned type are used in particular in motor vehicles. Filters are used in order to filter the fuel delivered to the engine of the motor vehicle on the fuel injection system of the motor vehicle and to remove unwanted foreign substances and water. [0003] The filter comprises a filter element, which is generally formed in the form of a filter cartridge and is accommodated in a filter housing of the filter. The filter housing usually consists of a housing cup and a housing cover, on which inlet openings and outlet openings are provided for the passage of fluid, in particular in the form of fuel. [0004] The filter element must ensure that the fluid cleaned by it is free from contamination. It must also be ensured that...
