Publication number: 20240066444Abstract: 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.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Inventors: Luca Piva, Fabrizio Buratto, Jason P.

Publication number: 20220074482Abstract: A panicle catcher for capturing entrained particles in a fluid is disclosed. The particle catcher can include an enclosure defining a flow channel between an inlet and an outlet. Trapping means may be incorporated into the particle catcher. Where provided, the trapping means can be arranged at or near the inlet to allow fluid comprising entrained particles to enter the flow channel through the inlet and to substantially prevent the fluid comprising entrained particles from exiting the flow channel through the inlet. Filtering means may also be incorporated into the particle catcher. Where provided, the filtering means can be arranged at or near the outlet to keep at least some a part of the entrained particles from exiting the flow channel through the outlet.Type: ApplicationFiled: November 27, 2019Publication date: March 10, 2022Applicant: Donaldson Company, Inc.Inventors: Enrico GRECO, Fabrizio BURATTO
