Abstract: A filtering device for fluids includes a filter housing (1) and a filter element (9) received in the filter housing. The filter element has an end cap (17) on at least one end. The end cap forms an enclosure for the corresponding end edge of the filtering material (23, 35) and is fixed on an element receiver (13) interacting with the bottom part (5) of the filter housing (1) to fix the position of the filter element (9) in its functional position. The element receiver forms a fluid path for the cleaned fluid exiting the hollow chamber (19) of the filter element (9). The element receiver (13) contains a valve arrangement (55) blocking the fluid path (35). A control device (79, 83) releasing the valve arrangement (55) in the functional position is on the end cap (17) of the filtering element (9). The end cap is fixed on the element receiver (13).

Abstract: A filter device has a filter housing (1) receiving a filter element (11) defining a longitudinal axis and being in the form of a filter cartridge. An end cap (19) forms an enclosure for the relevant end rim of the filter material (23, 25). The end cap fixes the position of the filter element (11) in its functional position by being on an element receiver (13) that interacts with the bottom part (7) of the filter housing (1). The element receiver (13) and the assigned end cap (19) of the filter element (11), on their parts (17 and 15) coming into engagement with one another in the functional position of the filter element are provided with shaped irregularities matched to one another to enable the engagement in a positional relationship directed towards one another.

Abstract: A device for drying medium flow (8), in particular an air flow, includes a device housing (2), in which at least first and second drying agents (4, 6) are received. The first and second drying agents have a high moisture absorption capacity in the case of low and high moisture values of the medium flow (8), respectively. The amount of the respective drying agent (4, 6) can be selectively set depending on the actual moisture present in the medium flow (8).

Abstract: The invention relates to a filtering device for fluids, comprising a filter housing (I). At least one filtering element (9) which is in the form of a filter cartridge and which defines a longitudinal axis (11) can be received in said filter housing. The filter cartridge has an end cap (17) on at least one end, said end cap fanning an enclosure for the corresponding end edge of the filtering material (23, 35). The end cap can be fixed on an element receiving means (13), which interacts with the bottom part (5) of the filter housing (1), in order to fix the position of the filtering element (9) in the functional position thereof. The element receiving means forms a fluid path for the cleaned fluid exiting the filtering hollow chamber (19) of the filtering element (9).

Abstract: The invention relates to a device for drying a medium flow (8), in particular an air flow, comprising a device housing (2), in which at least one first and at least one further drying agent (4, 6) are received, having high moisture absorption capacity in the case of low or high moisture values of the medium flow (8), and wherein the amount of the respective drying agent (4, 6) can be selectively set depending on the actual moisture present in the medium flow (8).

Abstract: A filter device having at least one filter housing (1), in which at least one filter element (11) that defines a longitudinal axis can be received in the form of a filter cartridge which has on at least one end an end cap (19) forming an enclosure for the relevant end rim of the filter material (23, 25), which end cap, for fixing the position of the filter element (11) in its functional position, can be fixed on an element receiver (13) that interacts with the bottom part (7) of the filter housing (1), is characterized in that the element receiver (13) and the assigned end cap (19) of the filter element (11), on the parts thereof (17 and 15) coming into engagement with one another in the functional position of the filter element are provided with shape irregularities which are matched to one another which enable the engagement in a positional relationship directed towards one another.
