Filter, Filter Element, and Filter Housing

Abstract

Disclosed is a filter (10) for liquid fluid, in particular lubricant, particularly motor oil, or fuel, in particular of an internal combustion engine, a filter element (16) and a filter housing (12). The filter housing (12) has at least one inlet (24) for fluid to be cleaned and at least one outlet (22) for cleaned fluid. The filter (10) has at least one hollow filter element (16), which is arranged in the filter housing (12) such that it separates at least one inlet (24) from at least one outlet (22). The filter element (16) has at least one filter medium (26), which is at least partly surrounding at least one internal space (28) of the filter element (16) circumferentially relating to an axis (20). The at least one filter element (16) has at least one passage (34) for connecting at least one internal space (28) fluid-ducting to at least one inlet (24) or at least one outlet (22). The filter (10) has at least one medium (48) for neutralization of acid in the fluid and/or for sequestering acid from the fluid, which is arranged in a fluid-ducting area of the filter (10) such that the fluid can come in contact at least with a part of the medium for acid neutralization/sequestration (48). At least one medium for acid neutralization/sequestration (48) is laminar and different from the at least one filter medium (26).
