Abstract: Various embodiments provide for a filter assembly including a filter head having one or more filter head threads and a filter cartridge. The filter cartridge includes a shell having a shell wall defining an internal volume and a collar disposed around and coupled to the shell, and a filter element. The collar includes one or more collar threads threadably engaged with the one or more filter head threads. The filter element is disposed within the internal volume. The filter element includes filter media and a first endplate coupled to the filter media at a filter media first end. The first endplate includes an endplate end wall and a first spacing member. The first spacing member extends axially away from the endplate end wall such that the first spacing member spaces the shell away from the filter head when the filter element is installed in the shell.

The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

Abstract: A filter element arranged exchangeably in a filter housing of a filter has a filter medium delimiting an element interior. An end body arranged at the filter medium has a fastening region surrounding the interior opening that communicates with the element interior. An insertion adapter for connecting the filter element to a fluid connector of the filter housing has an insertion sleeve insertable axially into the fastening region of the end body. The inward side of the fastening region is provided with a material that is initially flexible during manufacture of the filter element and hardens later on. The insertion sleeve has a holding element radially outwardly arranged at the circumference. With inserted insertion sleeve, the holding element is arranged in the fastening region. The initially flexible material of the fastening region flows behind the holding element and forms a form fit connection with the holding element when hardened.

Abstract: A removable and replaceable end cap that selectively lockingly engages a seat ring of a filter housing. The end cap may include a flange that compresses a gasket member between the end cap and the seat ring to form a fluid tight seal therebetween. The end cap may include cam locking grooves that may each receive insertion of a protrusion of the seat ring, and which are structured for at least rotational displacement about the received protrusion as the end cap is rotated between locked and unlocked positions relative to the seat ring. The end cap may also include an opening that accommodates the passage of a fluid to a filter element. The filter element, which may be coupled to the end cap, may be adapted to remove particulate or contaminate from the received fluid.

Abstract: A retrofit no filter no run insert for existing filtration systems manufactured without a no filter no run engine integrity protection feature. The insert is beneficial for a manufacturer that initially does not require the benefit of a no filter no run engine integrity protection feature but later requires such a feature. The insert can be installed into the existing filtration system without any modification to the existing filtration system head. The no filter no run insert prevents the equipment supplied by the filtration system (e.g., an internal combustion engine) from being operated without a filter element. Further, the no filter no run insert prevents the equipment supplied by the filtration system from being operated with an unauthorized or non-genuine replacement filter element. The no filter no run insert safeguards against damage to downstream components of the filtration system and malfunctions of equipment in which the filtration system is used.

Abstract: A fluid filter mountable on a connection flange having a central stand pipe, and having an exchangeable filter insert. The insert has a hollow cylindrical filter material body with two end plates on its end faces and is mountable on the stand pipe. A cup-shaped screw housing of the filter can be screwed to a free end of the stand pipe, and supports a seal on a free edge thereof, via which the screw housing is sealable against a connection flange sealing surface when mounted. The filter has a first arrangement on an end face area to center the end face area to the flange. The filter insert has a second arrangement on the end face area outer periphery for centering the screw housing free edge relative to the connection flange sealing surface, wherein the second arrangement interacts in a centering manner with the screw housing free edge when installed.

Abstract: An assembly forms a seal between components (11, 33) having sealing zones (37,51). The sealing zones face each other in a functional position of the components. A sealing element (43, 57) is on the sealing zone (37, 51) of one component (11, 33). A sealing surface (51) is on the sealing zone (37, 51) of the other component (11, 33) to form a radial seal. The components (11, 33) can be brought into the functional position by a relative movement in the axial direction. The sealing element (43, 57) sealingly interacts with the sealing surface (51) in the functional position. A third component (61) associated with an actuating part (62) acts on the sealing element (43;57) in the functional position of the components (11, 33) to deform the element to increase the sealing force.

Abstract: The invention relates to a filter device with a filter element (1) which can be received in a filter housing that consists of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by means of a screw connection (32, 33), and an additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). The invention is characterized in that in order to transmit a torque between threaded elements (33) of the screw connection (32, 33) and of the additional screw connection (41), said threaded elements being rotatable relative to each other, a coupling device (43, 46, 61) is added which allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the screw connection (32, 33) reaches the fixed rotational state.

Abstract: A liquid filter insert for a liquid filter has a prefilter element and a main filter element connected to the prefilter element. Prefilter element and main filter element are arranged on top of each other in an axial direction relative to a longitudinal axis of the liquid filter insert. A connection provides a flow path for liquid to flow from the prefilter element to the main filter element. The prefilter element is provided with a water separation unit and is further provided with a filter medium. The water separation unit is arranged between the filter medium of the prefilter element and the connection such that the liquid, after passing through the filter medium, flows through the water separation unit into the connection. The water separation unit has a water discharge channel for water separated from the liquid that extends axially at least partially through the main filter element.
