摘要： A filter device for treating fluids, in particular for filtering fluids such as fuel, oil, or water, has a housing (56) with a housing pot (58), a housing cover (60), at least one inlet (88) for the fluid to be treated, and at least one outlet (82) for the treated fluid. A connecting head (12) has at least one feed (16) for the fluid to be treated and connectable to the at least one inlet (88), and/or at least one discharge (18). The connecting head (12) and the treatment element (14) can be connected to each other by means of a releasable bayonet-type connecting device (34) through the execution of a rotational/plug-in movement about a connecting axis (20) of the treatment device (10).

摘要： A recirculation module for a fuel prefilter unit of a combustion engine has a temperature-controlled actuating element that transfers the recirculation module, based on a filter raw side feed temperature of the fuel, from a cold start state into a normal operating state and back. In cold start state, an engine return line from the combustion engine to the recirculation module is in fluid communication with a filter element raw side of the fuel prefilter unit and the engine return line is separated in regard to fluid communication from a tank return line of the combustion engine. In normal operating state, the engine return line is separated in regard to fluid communication from the filter element raw side and is in fluid communication with the tank return line. A check valve prevents return flow of fuel from the tank return line into the engine return line.

摘要： A filter device has a cup-shaped filter housing and a filter element disposed in the filter housing. A filter head is connectable to the filter housing and forms a cover for the filter housing. A spring element is provided that is acting on the filter element. The filter head has at least one first form-fit element. The filter housing has at least one second form-fit element for interacting with the at least one first form-fit element. The spring element is arranged such that the filter head and the filter housing for reaching a closed position, in which the at least one first form-fit element and the at least one second form-fit element engage each other, are movable relative to each other axially against the force of the spring element. The spring element clamps the filter element axially between filter head and filter housing in the closed position.

摘要： A filter element for filtering a fluid is provided with a housing and a filter body arranged in the housing. A cover closes off one end of the housing. An inlet is arranged on the cover at a raw side of the filter element for inflow of a fluid into the filter element. An outlet is arranged on the cover at a clean side of the filter element for discharge of the fluid from the filter element. The cover has a connecting area connecting the filter element with a counter element of a filter system. The cover has a sealing area that seals between the filter element and a receptacle of the filter system. A seal is disposed in the sealing area and has two separate sealing surfaces that effect a sealing action in the connecting area in axial direction and in radial direction of the filter element.

摘要： A filter element (10) comprises filter bellows (16), in particular open filter bellows made of a filter medium (18), which has an oncoming flow side (28) and an outgoing flow side (30) for the fluid to be filtered. The filter element (10) is disposed in the filter housing (11) in such a way that it separates at least one inlet (15) from at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) may be aligned in parallel with or axially to the installation direction (12) in the filter housing (11) for installing the filter element (10). The filter element (10) has at least one outer support section (38), which protrudes axially beyond the filter bellows (16) on the oncoming flow side (28) or the outgoing flow side (30) with respect to the element axis (14) and protrudes into an axial projection of the oncoming flow side (28) or the outgoing flow side (30) with respect to the element axis (14).In addition, a respective filter housing (11) and/or a respective filter (13) is/are described.
