Abstract: A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube.

Abstract: A fluid filter has a filter housing with a first filter housing part that has an installation opening for an exchangeable filter element and is closeable with a second filter housing part. The first filter housing part has a first sealing surface and the second filter housing part has a second sealing surface interacting with the first sealing surface. The filter element has a seal circumferentially and radially extending relative to a filter axis. The seal is arranged between the first and second sealing surfaces when the filter element is correctly installed. The seal has a positioning contour in which a course of the seal at least in one section has an axial directional component relative to the filter axis. The first and second sealing surfaces each have an appropriate positioning counter contour which receive the at least one positioning contour when the filter element is correctly installed.

Abstract: A mounting assembly is described that has an interface designed to increase the stress margin of at least the module side of the assembly, for example in a liquid filtration module, and to increase ease of assembling its mounting components. The interface reduces the failure of the mounting assembly at least on the module side, so that if failure of the mounting assembly occurs, such an occurrence is less likely to be at the interface and on the module side, thereby reducing the need to replace more complex and expensive components that may be on the module side. Generally, the mounting assembly includes a mounting interface and a mounting bracket connectable to the mounting interface. A retention component is configured to maintain connection of the mounting interface to the mounting bracket.

Abstract: Provided is a filter element includes an end cap having at least one stop member extending radially outwardly from an outer surface, the at least stop member having at least one stop surface for contacting a tab on a slip thread collar of a filter head assembly. When the filter element is coupled to the filter head assembly, the filter element prevents rotation of the slip thread collar relative to a filter head, thereby allowing threads on the slip thread collar to mate with threads on a filter bowl to couple the filter head assembly to the filter bowl. The interaction between the filter element and filter head assembly prevents the filter head assembly from being coupled to the filter bowl when the filter element is not installed.

Abstract: A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system.

Abstract: A fluid filter comprising a housing, a releasable cover and a replaceable filter having a filter body and two end plates. The filter is placed on a housing standpipe which has on its free side, facing the cover, an axially displaceable endpiece. The endpiece is preloaded in the expulsion direction and in that position is blocked by a locking system against insertion which prevents the cover from connecting with the housing. An unlocking device guided by the filter unlocks the locking system and allows insertion of the endpiece. The locking system is formed by locking tabs which are radially movable, and each have a locking face facing in the axial direction. The tabs are preloaded in the locking direction and each lock the endpiece in its expelled position against axial insertion relative to the standpipe. The tabs can be radially moved into their unlocking position by the unlocking device.
