Patent ID: 7662216

Claim:
An in-line filter assembly comprising an inlet duct housing, an intermediate housing having an axially extending inner sidewall, and an outlet duct housing axially aligned in-line along an axis, said inlet duct housing mating with said intermediate housing at a first interface, said outlet duct housing mating with said intermediate housing at a second interface, a filter element in said intermediate housing and filtering fluid flowing axially therethrough from an upstream dirty side to a downstream clean side, said first interface being upstream of said filter element, said second interface being downstream of said filter element, a first seal sealing said filter element to said intermediate housing at said inner sidewall and preventing bypass of dirty unfiltered fluid from said upstream dirty side of said filter element to said downstream clean side of said filter element, a second seal sealing said intermediate housing to said outlet duct housing at said second interface downstream of said filter element and preventing entry of dirty unfiltered fluid through said second interface downstream of said filter element, said first seal being a radial seal axially slidable along said inner sidewall of said intermediate housing, said filter element being axially insertable into said intermediate housing with said radial seal axially sliding along said inner sidewall of said intermediate housing.
