A filter cartridge of a filter group of a fluid of a vehicle extending along a main axis has a base assembly and engagement members, including first engagement members in the filter cartridge and second engagement members in the base assembly, shaped to block each other. The filter cartridge extends along a cartridge axis and includes an engagement plane on which the first engagement members are made having tooth elements diametrically opposite the cartridge axis. Each tooth element extends from the engagement plane parallel to the cartridge axis, having a stalk and a head. In the blocking configuration, the second engagement members engage the head. Each tooth element is radially elastically yielding, so the blocking configuration is achievable following radial movement of the tooth element. The first engagement members include for each tooth element a command device extending radially. Radial movement of the tooth element actuates the command device.

A filter assembly including a housing (15) and a filter cartridge (10). The housing has a housing inlet (16) and a housing outlet (17). The filter cartridge (10) has a filter inlet (11) fluidly connected to the housing inlet (16) and a filter element (12) between a top cap (18) and a bottom cap (19). The top cap (18) and the bottom cap (19) create a circular guiding system. The bottom cap (19) has a first part (19a) that receives the filter element (12) and a second part (19b) that is connected with a mating surface (20) of the housing. The second part has a first circular section (21a) and a second section (21b) and the first section has another shape than the second section (21b), such that the bottom cap (19) cannot rotate in relation to the mating surface.

A filter comprising a filter housing (10) and a replaceable filter element (12) arranged in the filter housing (10) and having annular upper and lower end members (12a, 12b) and an inner space, wherein the filter housing (10) comprises a housing pot (10a) having a fluid in-let (10e), a fluid outlet and an opening (10b) for inserting the filter element (12). The filter has a support tube (16) extending in the inner space of the filter element (12) and connected to a bottom of the filter housing (10) and a locking member (14), the locking member (14) being adapted to engage the support tube (16) and generate a holding or pushing or pulling force supported on the filter housing via the support tube (16) for holding or pushing or pulling the filter element (12) into or out of the housing bowl (10a).

A filter cartridge assembly for an ice making appliance having a rectilinear filter cartridge with a plurality of partitions that are positioned within an internal chamber, form multiple sub-chambers, and create a non-linear pathway for the flow of water through the filter cartridge. Filter media positioned in the sub-chambers of the filter cartridge are configured to remove dissolved solids from water travelling through the filter cartridge and used by the appliance to create ice, including clear ice.

A filter cartridge of a filter group of a fluid of a vehicle extends along a main axis including a base assembly and engagement members including first engagement members in the filter cartridge and second engagement members in the base assembly, respectively specially shaped to engage each other in a blocking configuration. The filter cartridge extends along a cartridge axis and includes at an axial end an engagement plane on which the first engagement members are made including at least two tooth elements diametrically opposite the cartridge axis. Each tooth element extends in height from the engagement plane extending on an imaginary surface parallel to the cartridge axis, having a substantially T shape. Each tooth element is elastically yielding in a radial direction, so that the blocking configuration is achievable following the radial movement of the tooth element.

A filter for gravity-fed applications, having filter media with a hollow center, the filter being generally prone to a degradation or cessation in fluid flow due to air entrapment or air lock within the filter housing cavity, which develops during filtering. A diffuser element is introduced to pierce the entrapped air bubble, the diffuser element being an elongated structure connected to the filter housing top end cap and extending through the entrapped air bubble to the filter media.

Provided is a cartridge assembly having first and second cartridges sealed by an interface member having a first sealing member along a radially outer surface thereof having a non-planar geometry around the outer surface and a second sealing member along the radially outer surface having a non-planar geometry around the outer surface. The sealing members may each have a repeating, undulating, non-planar geometry around the outer surface. The cartridges have ends with matching geometries to allow the cartridges to engage in surface-to-surface relation around their entire extents to create with the interface member an air tight seal.

Various embodiments relate to a filter element. The filter element includes a first endplate that defines a first endplate opening and a second endplate. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A support structure is disposed within the central opening of the filter media and is attached to the first endplate and the second endplate. The support structure includes an axial lobed extension that extends from a first end of the support structure to a second end of the support structure. The support structure is configured to resist collapse of the filter element.

A filter element is disclosed. The filter element may include filter media extending circumferentially around and longitudinally along a longitudinal axis of the filter element. The filter element may also include pilot structure attached to the filter media and configured to locate the filter element. The pilot structure may include an axial cross-section that includes at least one of a noncircular feature or an asymmetrical feature relative to the longitudinal axis.

A filter unit includes a body portion with first and second engagement surfaces that traverse at least a part of the body portion. The first and second engagement surfaces include a first segment that extends substantially parallel with a longitudinal extent of the body portion and a second segment that extends at an angle relative to the first segment. An engagement protrusion extends from the body portion and has a water inlet and a concave engagement wall with a water outlet. A periphery of the concave engagement wall includes a first portion with a first radius of curvature and a second portion with a second radius of curvature that is larger than the first radius of curvature. A first seal is disposed on a sidewall of the engagement protrusion proximate the water outlet. A first cross-section of the engagement protrusion, taken at the first seal and perpendicular to the longitudinal extent of the body portion, is egg-shaped with only one axis of symmetry. A second seal is disposed on the engagement protrusion and spaced apart from the first seal. A second cross-section of the engagement protrusion, taken at the second seal and perpendicular to the longitudinal extent of the body portion, is egg-shaped.
