Embodiment Construction

[0015] Referring generally to the drawings, embodiments disclosed herein relate to a filter retained within a housing shell using a snap-fit ​​connection. The filter includes an end plate with snap features that mate with grooves located inside the housing shell. The groove may extend 360 degrees around the inner circumference of the housing shell. Therefore, when the housing is unscrewed from the head for maintenance (such as during filter replacement maintenance), the housing only needs to move the length of the inner radial seal contact surface between the housing and the head, rather than the entire length of the filter media, Thereby minimizing the travel length of the filter assembly requiring servicing. The filter can be a gas filter or a liquid filter. In some arrangements, the filter is a natural gas filter, more specifically a natural gas coalescing filter.

Abstract

A filter that is held within the housing housing using a snap fit. The filter includes an end plate with snap features that mate with grooves inside the housing shell. The groove may extend 360 degrees around the inner circumference of the housing shell. Thus, when the housing is unscrewed from the head for servicing (eg during filter replacement), it is only necessary to move the housing the length of the inner radial seal interface between the housing and the head, and not the length of the filter media. the entire length, thereby minimizing the stroke length required to service filter assemblies.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 975063, entitled "Snap-in-Place Natural Gas Filter," filed April 4, 2014, which is incorporated by reference in its entirety for all purposes way into this article. technical field [0003] This application relates to filtration systems, and more particularly this application relates to replaceable filter cartridges with snap-fit ​​connections for natural gas systems. Background technique [0004] Natural gas filters are typically located along natural gas lines (eg, pipes, hoses, lines, etc. that supply natural gas to devices such as internal combustion engines) and filter liquid and solid contaminants from the natural gas fluid. In a typical cylindrical filter assembly, a cylindrical filter element is disposed within a cylindrical housing housing. The cylindrical housing shell can be threaded to the head in the natural gas line. This head de...
