Problems solved by technology

This can be disastrous for equipment requiring filtration
Also, when there are multiple filter assemblies in close proximity to each other on a system, sometimes on a common filter head, filter service personnel can sometimes get confused as to which filter assembly goes where—putting the wrong filter Incorrect placement of filter components on the filter head can lead to catastrophic results

Embodiment Construction

[0055] A. Overview

[0056] The figures illustrate example embodiments of filtration systems including filter assemblies and filter heads. It should be understood that many examples are conceivable and not shown in the drawings. figure 1 A filter system 40 including a filter head 42 and a filter assembly 44 is shown.

[0057] exist figure 1 , a fully assembled filter system 40 is shown, while in figure 2 , a cross-sectional view of filter system 40 is shown. Assembly 44 is selectively attachable and mounted on filter head 42 . The filter head 42 interfaces with other equipment including, for example, the engine's lube oil system, the fuel system for the engine, the hydraulic system for heavy equipment, and the corresponding systems for generators for industrial use.

[0058] Filter assembly 44 includes a filter cartridge 46 and a cartridge housing 48 . The filter element 46 can be a removable and replaceable filter element 46 relative to the filter element housing 48;...

Abstract

A filter cartridge includes a key ring with at least first and second protrusions to engage a lock-out assembly in a filter head, permitting the cartridge to connect to the filter head. A filter system includes a filter assembly, including a filter cartridge and a cartridge housing, connected to a filter head, in which the filter head includes an adapter assembly with a lock-out mechanism. The lock-out mechanism is unlocked by a key ring on the filter cartridge. A method of installing a filter assembly includes using protrusions on a key ring on a filter cartridge to unlock an adapter assembly in a filter head to allow for connection between the filter assembly and the filter head.

Description

[0001] This application was filed on November 3, 2010 as a PCT international patent application, and the applicants in all countries except the United States were designated as Donaldson Corporation, an American company. When only the United States was designated, the applicants were Bradley S.Honermann and John R.Hacker, both US citizen, and claims priority to US Provisional Patent Application Serial No. 61 / 258,395, filed November 5, 2009. technical field [0002] The present invention relates to filtration assemblies and methods. In particular, the present invention relates to filter assemblies and methods for filtration of liquids, such as lube oil filters, hydraulic filters, and fuel filters. Background technique [0003] Filters are often used in conjunction with lubrication and fuel systems of internal combustion engines and hydraulic systems of heavy equipment. Filters are also used in many other types of fluid systems. In these types of systems, the filters are cha...
