A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base.

A filter device may include a filter housing and a filter element defining a longitudinal axis disposed in the filter housing. The filter element may be configured to be penetrated by a fluid flow in a radial direction from a raw end to a pure end of the filter element. A water separator may be disposed at the pure end of the filter element and arranged axially spaced from the same. The water separator may have a hydrophobic and annular diaphragm extending in an axial direction of the filter element configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow.

A tool for draining and removing a vehicle filter (e.g. an oil filter, an air filter, a coolant filter, a fuel filter, or the like) from a vehicle, and a method for removing a vehicle filter from a vehicle. The tool includes a perforator for providing a perforation in a vehicle filter; a housing comprising a cavity and an opening therein for receiving a fluid from a perforation in a vehicle filter into the cavity, the perforator at least partially located in the cavity, and the opening being configured such that least one of the perforator and a vehicle filter are positionable therethrough; and a gripper connected to the housing and comprising a gripping surface for engaging and gripping a vehicle filter to restrict relative rotation between the gripper and the vehicle filter to permit rotation of a vehicle filter by rotation of the tool.

A filter device includes a functional element and a filter element arranged in a filter housing. The filter element includes an enclosure positioned about a central axis and below filter material of the filter element. The enclosure includes an enclosure wall that defines an inner volume that is in fluid communication with an orifice of the functional element when the filter element is positioned over the functional element.

A fluid filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface. The inner surface surrounds the longitudinal axis and defines a hook portion. The proximal end cap is disposed within the housing and includes a flange engaging the inner surface of the housing. The nut plate is disposed within the housing and includes a proximal end and a distal end. The proximal end engages the hook portion of the housing. The distal end engages the proximal end cap.

The invention provides filters and methods of assembling filters. In an exemplary embodiment, the filter includes a porous element, a compression element, and a housing. The compression element can be configured to receive the porous element, thereby forming an assembly. For example, the compression element can receive the porous element in a slip-fit relationship. The housing can have an opening formed therein that is configured to receive the assembly. In some embodiments, the assembly can be retained within the opening when the assembly is received therein. For example, the opening can receive the assembly in a press-fit relationship.
