Embodiment Construction

[0018] refer to figure 1 and Figure 5 , filter 10 is shown with filter head 12 attached. A filter head 12 may be disposed within the engine or elsewhere for receiving the filter 10 . In one embodiment, filter 10 is a lube oil filter that filters oil used by the engine. However, filter 10 may be other types of filters for filtering other types of engine fluids, such as fuel or hydraulic fluid. Additionally, filter 10 may be used in non-engine applications and may be used to filter other types of fluids, including water or air.

[0019] The filter 10 includes a housing 14 made of metal or plastic. Housing 14 includes closed end 15a (as Figure 5 shown) and the open end 15b closed by the nut plate 16. The interior of the housing 14 is provided with a filter medium 18 for filtering fluids such as oil, fuel, hydraulic fluid or other fluids that enter the filter 10 for filtering. Those of ordinary skill in the art will appreciate that the nut plate 16 has one or more inlet o...

Abstract

A spin-on fluid filter with improved attachment and sealing with the filter head. The filter has a gasket positioned at the end of threads used to connect the filter to a filter head. The described design protects the gasket from excessive engine heat, cut or tear damage during installation, and the roll out effect of installation torque. In addition, the described attachment provides gasket protection and uniform compression of the gasket. The gasket can be any type that provides a seal which keeps external threads on the filter and the filter head dry.

Description

technical field [0001] The present invention describes a spin-on filter with improved attachment and structural sealing with the attachment. technical background [0002] Conventional spin-on filters have an external gasket disposed at or near the end of the filter for sealing against the filter head on which the filter is mounted. However, the location of the gasket makes it prone to tearing or pinching during filter installation. Also, in some cases the gasket may be exposed to excessive engine heat dissipation. Contents of the invention [0003] A filter attached to a mounting structure such as a filter head is described herein. The filter is designed to provide a shield for the built-in gasket that isolates the gasket from engine heat dissipation, thread contamination during maintenance, and installation damage. [0004] In one specific embodiment, the filter is a spin-on filter connectable to a filter head of an engine and filters oil or other engine fluid. Howeve...
