Title: FILTER HOUSING AND INTERMEDIATE FLOOR
Abstract:
The invention relates to a filter housing (1), comprising a receptacle (11) for holding a filter module of a vehicle, an inlet (7) for feeding unfiltered fluid to an unfiltered side (9) of the filter module, an outlet (8) for leading away filtered fluid from a filtered side (10) of the filter module, a passage opening (3) for establishing fluid communication between the outlet (8) and the filtered side (10) of the filter module, a bypass opening (4) for establishing fluid communication between the outlet (8) and the unfiltered side (9) of the filter module, a first non-return element (5) for selectively closing the passage opening (3), and a second non-return element (6) for selectively closing the bypass opening (4), the first non-return element (5) blocking fluid flow from the outlet (8) of the filter housing (1) to the filtered side (10) of the filter module, and the second non-return element (6) blocking fluid flow from the unfiltered side (9) of the filter module to the outlet (8) of the filter housing (1). The invention further relates to an intermediate floor for inserting between a filter module and a filter housing (1) of a vehicle, the filter module being insertable into a receptacle (11) of the filter housing (1), the intermediate floor comprising a passage opening (3) for establishing fluid communication between an outlet (8) and a filtered side (10) of the filter module, a bypass opening (4) for establishing fluid communication between the outlet (8) and a filtered side (9) of the filter module, a first non-return element (5) for selectively closing the passage opening (3), and a second non-return element (6) for selectively closing the bypass opening (4), the first non-return element (5) blocking fluid flow from the outlet (8) of the filter housing (1) to the filtered side (10) of the filter module, and the second non-return element (6) blocking fluid flow from the unfiltered side (9) of the filter module to the outlet (8) of the filter housing (1).
