ABSTRACT:

TECHNICAL FIELDS
This disclosure concerns generally a fluid filter. In particular, this disclosure relates to a filter incorporating an improved seal arrangement.
BACKGROUND
Filters have been employed in a variety of applications including hydraulic systems and engine lubrication systems. Such filter assemblies generally include a cylindrical filter element within a can or housing with a baffle or attachment plate at one end to connect the filter to a filter head, typically by a threaded joint. A central opening and several surrounding openings in the baffle direct flow through the filter and, in particular, the filter element. The flow can be in either an inside-out (forward flow) or an outside-in (reverse flow) pattern. A circular gasket serves as a seal between the baffle and the can or housing.
Various models and designs of filters have been known over the years. Each design improves on an aspect of these filters. Continued improvement in filters are desired.
SUMMARY OF THE DISCLOSURE
In one aspect, a fluid filter assembly is provided. The fluid filter assembly includes a housing having a closed end and an open end; a filter element operably oriented in the housing; a baffle plate mounted to operably cover the housing open end; the baffle plate including a first axial face defining at least a first sealing groove; and a sealing gasket oriented in the first sealing groove; the sealing gasket forming a seal between the housing and the baffle plate.
In other aspects, methods of constructing, installing, and servicing includes fluids filters of the type described.
