The filter element (1) includes a receiving part (19) which, when the filter element (1) is located in the filter housing (3; 4) in the operational position, comes into fluid communication with a housing part (17; 18) of the filter housing (3; 4) to form a fluid connection (9). The receiving part (19) of the filter element (1) has an inner, first guiding path (37) for sealing contact to the housing part (17) of the filter housing (3) according to a first mode of construction and an outer, second guiding path (51) for sealing contact to the housing part (18) of the filter housing (4) according to a second mode of construction.

Abstract: A filter device has a filter element (17) that is exchangeably disposed in a filter housing (1). The filter element (17) is provided on one end with an end cap (23) that forms a surround for a rim of a filter material (31). The end cap (23) has a connector (43) attaching the filter element (17) in an operating position to an element seat (19; 45) inside the filter housing (1) such that a fluid-impermeable connection is formed between filter housing (1) and filter element (17). The connector (43) enables the positionally fixed mounting of the filter element (17) and the formation of a fluid-impermeable connection in conjunction with element seats (19; 45) of filter housings (1) of different designs.

Abstract: A filter device has a filter element (3) in a filter housing (1). Corresponding threads (23, 33) form a screw connection between a housing cover (5) of the filter housing (1) and the filter element (3). A seal (29, 35) is between the filter element (3) and the housing cover (5). The screw connection is formed by threads (33) on a connecting pipe piece (31) that is part of an end cap (17) of the filter element (3) and that extends into the inner filter cavity (22) and by the threads (23) of the housing cover (5). The housing cover threads (23) are on a receiving pipe piece (21) formed by a separate component attached to the housing cover (5).

Abstract: A filter device comprising at least one filter element (17) that is exchangeably disposed in a filter housing (1), wherein said filter element (17) is provided on at least one end with an end cap (23) that forms a surround for a rim of a filter material (31), wherein said end cap (23) is provided with a connector (43) with which the filter element (17) may be attached in an operating position to an element seat (19; 45) inside the filter housing (1) in such a way that a fluid-impermeable connection is formed between filter housing (1) and filter element (17), characterised in that the connector (43) enables the positionally fixed mounting of the filter element (17) and the formation of a fluid-impermeable connection in conjunction with element seats (19; 45) of filter housings (1) of different designs.

Abstract: A filter device has a filter element (3) received in a filter housing (1) and has a holding device (19) for detachably fixing the filter element in the filter housing (1). Corresponding threads (23, 33) form a screw connection between a housing cover (5) of the filter housing (1) and the filter element (3). A sealing device (29, 35) imparts a sealing action between the filter element (3) and the housing cover (5). The screw connection is formed by threads (23, 33) situated in the interior (22) of the filter element (3). The thread (33) assigned to the filter element (3) is situated on a connecting pipe piece (31) that, as a constituent part of an end cap (17) of the filter element (3), extends into the inner filter cavity (22) of the filter element (3). The thread (23) assigned to the housing cover (5) is situated on a receiving pipe piece (21), which can be screwed to the connecting pipe piece (31) of the filter element (3).

Abstract: A filter device has a filter housing (1, 3) releasably accommodating one filter element (15) and has a housing pot (1) surrounding the filter element (15) and a removably attachable housing head (3) with fluid passage (39) for the discharge of filtrate. A valve device in the fluid passage includes a closing body (53) blocking the discharge flow in its closed position and facilitates the discharge flow in its release position. A locking device includes a blocking member (57) locking the closing body (53) in its closed position. The blocking member (57) can move out of its locking position into its unlocking position by a control element (81) on the filter element (15). When the filter element (15) is situated in its functional position in the housing pot (1), the control element impacts the blocking member (57) as the housing head (3) is attached to the housing pot (1) to move the blocking member axially to its unblocking position.
