Filter, hollow filter element, and filter housing of a filter, and seal of a hollow filter element

Abstract

A filter () for filtering fluid, in particular air, water, fuel, oil, or urea-water solution, in particular of an internal combustion engine, in particular of a motor vehicle, a multiple-bellows hollow filter element (), a filter housing () of a filter (), and a seal () of a hollow filter element () are described. The filter () comprises at least one filter housing (), which comprises at least one inlet () for fluid to be filtered and at least one outlet () for filtered fluid. At least one hollow filter element, in particular a multiple-bellows hollow filter element () can be arranged in the at least one filter housing () such that it separates the at least one inlet () from the at least one outlet (). The at least one filter housing () comprises at least one first housing part () having at least one installation opening () for the at least one hollow filter element (), which can be closed using at least one second housing part (). The at least one hollow filter element () comprises at least one filter bellows (), which comprises at least one filter medium (), through which flow can occur for filtering of the fluid. The at least one filter bellows () at least partially delimits at least one element interior (). An element axis () of the at least one hollow filter element () extends coaxially, axially, or in parallel in relation to an installation/removal axis of the at least one hollow filter element (), in relation to which the hollow filter element () can be installed in the filter housing () and removed from the filter housing () through the at least one installation opening () in parallel, axially, or coaxially.
