A pipeline filter assembly comprising a base assembly, an outer wall, and a lid assembly. The outer wall has a lower end portion and an upper end portion, wherein the upper end portion comprises a lower collar, and the lower collar comprises at least one lock notch spaced around an exterior surface thereof. The lid assembly is configured to couple to the lower collar of the outer wall. The lid assembly has an upper collar configured to threadedly mate with the lower collar. The upper collar has at least one housing that projects from the upper collar, the housing having an interior surface, and at least one biasing clip pivotally mounted within the housing for releasable engagement with the lock notch. A pair of pipeline filter assemblies, wherein at least one connection plate is used.

The present invention relates to a filter element comprising an oil filter port adapted to be in fluid communication with an oil port of an engine the oil filter port includes threads for attaching the filter element in the oil port of the engine. Thus, the inventors realized that by providing the oil port with threads, the oil port of the filter element may be tightened in the oil port of the engine to in this way ensure axial locking of the filter element in the engine. The present invention also relation to a corresponding filter housing.

A filter element includes a first end cap, a second end cap, and an intermediate end cap disposed between the first end cap and the second end cap. A ring of first filter media circumscribing a first central cavity is disposed between the first end cap and the intermediate end cap. A ring of second filter media is disposed between the intermediate end cap and the second end cap. The filter element also includes an air-bleed conduit axially extending through the first central cavity and comprising a first portion integrally formed with the first end cap and a second portion integrally formed with the intermediate end cap and configured to connect to the first portion thereby forming a conduit for transmitting fluid.

An oil filter for a motor vehicle includes a filter cartridge disposed in an oil filter housing. A piston of the filter cartridge is displaceable in the oil filter housing in an axial direction of the filter cartridge. The filter cartridge has a closure element where the closure element is held at an end of at least one strut of the filter cartridge and where a free end of the at least one strut is supported in the oil filter housing. The piston is displaceable relative to the at least one strut in the axial direction of the filter cartridge.

A disposable dental waste filter device has a body having a tube receiving end having an outlet and a cap receiving end, a cap portion having an inlet and an end for insertion into the cap receiving end, a valve insert assembly for insertion into the body and the cap portion, and a filter assembly positioned within the body.

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

A system for further filtering a liquid extract material after an initial extraction process. In an embodiment, the system includes a semi-rigid filter cup that is substantially cylindrical, the filter cup having a top and a bottom, wherein the top is oriented to receive filter media prior to a filtration process, and material to be filtered during the filtration process. The filter cup includes an integrated deformable flange at the top of the filter cup, an integrated top o-ring that is integrated into the top of the integrated deformable flange and an integrated bottom o-ring that is integrated into the bottom of the integrated deformable flange.

A filter cartridge is for a vehicle fluid filter group that includes a filter body and cartridge engagement members in the filter cartridge and body engagement members in the filter body. The cartridge engagement members and body engagement members are configurable by mutual axial movement between an engagement configuration and a disengagement configuration. The cartridge filter includes an end plate with the cartridge engagement members arranged around the cartridge axis. The cartridge engagement members include two blocking groups, each blocking group including a blocking element. Each blocking element includes a stem and a tooth laterally projecting from the stem and defining an engagement undercut. In the blocking configuration, the tooth is in a housing region of the body engagement members, and an engagement projection is housed in the undercut. In axial movements, each stem yields elastically radially and/or laterally upon action of the engagement projection on the tooth.

The present invention relates to a filter element for the filtration of fluids, in particular hydraulic oil, having at least one end plate and a filter material which has a hollow-cylindrical shape and is connected to the end plate at an end face, wherein the end plate is designed to transmit a torque to a housing part, in particular a filter cover and/or a filter pot, of a filter device, wherein the end plate has at least one form-fitting element for receiving a torque and at least one transmission region for transmitting the torque to the housing part. The invention also relates to a filter device, an arrangement and an assembly method.
