Abstract:
A top load liquid filter assembly includes a filter lockout mechanism to ensure that the filter base and cover are not connectable unless there is a proper filter cartridge installed therein. The filter system can also include an automatic drain mechanism and a cartridge retention mechanism. One example embodiment further includes an air bleed vent. A filter cartridge usable in the topload liquid filter assembly includes first and second protrusions and cover-gripper members. Methods of use, installing, servicing, and retaining can be practiced.
Abstract:

Abstract:
A filter and replacement filter cartridge is provided with a pulsation dampener mounted and sealed to the filter cartridge basket at an inner diameter thereof. The pulsation dampener is captive to the basket such that removal of the basket from the filter housing canister removes all of the basket, filter media, and pulsation dampener as a single unit without separate, loose parts thereof. An axial extension section of the basket facilitates gripping and removal, and maintains a fully seated installed filter position. Sealing is provided without a section of the pulsation dampener interposed between the filter housing canister and lid.
Abstract:
Liquid filter assemblies, features, components and methods are described. In general, a liquid filter cartridge is provided which includes features that help ensure that when the assembly is serviced, the cartridge positioned within the assembly is a proper one, in proper sealing orientation, for appropriate use. Features that can be used to provide for this include: a seal on the filter cartridge that defines a seal pattern non-orthogonal to a plane perpendicular to a central axis of the filter cartridge; and, a member of a projection/receiver arrangement on the filter cartridge which is orientated to engage a portion of a liquid filter assembly, for example a liquid flow collar, to allow sealing when the cartridge is a properly positioned cartridge and a properly configured cartridge. Assembly features are described. Also, a flexible radial projection arrangement providing snap-fit interaction between a cartridge and housing is provided. Methods of assembly and use as described.
Abstract:
A filter cartridge is described that is designed to accommodate for example dual stage filtration. The filter cartridge has an endplate structure formed of a heat cured material, such as polyurethane, where at least one of the top end and the bottom end of the outer filter and the inner filter are embedded within the heat cured material. The heat cured material can provide an endplate structure that is convenient for manufacture and that has one or more sealing surfaces to seal with a housing that the filter cartridge is assembled with. For example, the heat cured material of the endplate can seal non-filtered fluid from filtered fluid that has passed through each of the filtration stages available in the cartridge.
Abstract:
A replaceable filter has a filter housing with a cylindrical connecting end. A housing lid has a cylindrical counter connecting member matching the cylindrical connecting end. A filter closure system seal-tightly connects by form fit the cylindrical connecting end and the cylindrical counter connecting member when the connecting end is inserted or pushed onto the counter connecting member in an axial connecting direction and moved relative to the counter connecting member. An annular member is arranged coaxially relative to the connecting end and has a terminal edge area that is connected seal-tightly to the filter housing such that the annular member and the connecting end define a receptacle for the cylindrical counter connecting member. A sealing device is arranged in the receptacle and connected to the filter housing. The sealing device interacts with the counter connecting member.
Abstract:
The present disclosure pertains to a fluid filter having integral attachment means which may take the form of a threaded portion of a filter cartridge. The threaded portion threadably interacts with a complementary threaded portion of a filter mounting to retain the filter cartridge to the filter mounting. The disclosure also pertains to a fluid filter having a cartridge made from two plastic shells welded together. The disclosure also pertains to a fluid filter with filter media positioned within a filter cartridge by an end cap with extending ribs welded to one of the two shells which compose the filter cartridge.
Abstract:
A reservoir-less fuel delivery module (10) for a fuel tank of a vehicle includes a flange (26) constructed and arranged to be mounted to an opening in a fuel tank of a vehicle. The module includes a pump and filter structure (20) having a fuel pump (14) and a fuel filter (24) surrounding at least a portion of the fuel pump for filtering fuel exiting the fuel pump. The module includes a mounting member (30) to which the pump and filter structure is mounted. Clip structure (34) couples the mounting member to the flange so that the pump is decoupled from the flange.
Abstract:
A liquid filter suitable for motor vehicles which includes a filter head (11), a vessel (12) and a filter element (16) disposed within the vessel (12) sealingly separating an inlet (14) from an outlet (15) such that liquid from the inlet must flow through the filter element to reach the outlet. The filter element (16) has guide projections (27, 28) positioning the filter element (16) within the vessel (12). Prior to installation, the filter element (16) is preassembled into the vessel (12) and fixed in position by pushing the filter element (16) into an element guide (29), after which the preassembly is screwed onto the filter head (11). When the vessel (12) is unscrewed from the filter head (11), the filter element (16) slides out of the element guide (29) and moves axially upwardly to free a volume V. Liquid flowing into the vessel (12) from the higher regions of the liquid filter (10) can flow into this volume, thus enabling drip-free replacement of the filter element.
Abstract:
A fluid filtration system is disclosed comprising a manifold assembly comprising a mounting bracket, an alignment collar connected to the mounting bracket, and a latch assembly moveable with respect to the mounting bracket and alignment collar. The system further comprises a filter cartridge comprising a filter cartridge outer surface and a cartridge latching structure formed on the filter cartridge outer surface to interact with the latch assembly. When the filter cartridge is aligned with the alignment collar and inserted into the manifold assembly, the filter cartridge is (i) latched into the manifold assembly by translating the filter cartridge into the manifold assembly to cause movement of the latch assembly to engage the cartridge latching structure; and (ii) unlatched from the manifold assembly by translating the filter cartridge into the manifold assembly to cause movement of the rotating latch assembly to disengage the cartridge latching structure.
