Embodiment Construction

[0024] The disclosed housing in the present application will be described primarily in connection with fuel filters. The housing is designed for multiple parallel plumbing of fuel filters, as will be described in connection with FIG. 4. The housing, however, can also be used to form a full flow oil filter, a hydraulic filter or a bypass filter. Some of these applications will also be illustrated to show the universality of the filter system.

[0025] Turning then to the drawings, and particularly to FIGS. 1 and 2, there are shown many of the basic elements of the housing portion of a filter system 20 constructed in accordance with the present invention. The system 20 is based on a housing 21 which has a plurality of ports 22 on the face thereof which allow configuration for a variety of applications. Of significance, the housing 21 is provided with a removable base 24; as will be described below, a number of different bases 24 can be provided to alter the application for which the fil...

Abstract

A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of “universality” features including a changeable bottom which allows the housing to operate as a fuel filter, a lubrication filter, or a hydraulic filter in different applications. The housing and cartridge are configured to provide support for the plastic elements of the cartridge to prevent crushing of the filter under normal and abnormal filter operating conditions. A key system associated with the cartridge and the housing provides assurance that the correct filter is installed for a particular application.

Description

CROSS-REFERENCE TO RELATED PATENT APPLICATIONS [0001] This patent application is a divisional of copending U.S. patent application Ser. No. 10 / 457,733, filed Jun. 9, 2003, which claims the benefit of U.S. Provisional Patent Application No. 60 / 387,235, filed Jun. 7, 2002, both of which are incorporated by reference in their entirety herein.FIELD OF THE INVENTION [0002] This invention pertains to filters, and more particularly to a filter system using an environmentally friendly filter cartridge. BACKGROUND OF THE INVENTION [0003] Most conventional filters and filter cartridges present a disposal problem. Driven by ease of installation, many applications have gone to self-contained spin-on cartridges. These have a metal outer case, a metal base plate, and other metal components within the filter. Replaceable cartridges also have significant metal components, often in the form of centertubes or support grids for supporting the filter element, and metal endcaps. Thus, significant elemen...
