Abstract
A filter assembly is formed of an impervious elongated tubular housing and an elongated filter member positioned within the housing with its opposed longitudinal edges sealed to the housing internal tubular surface. A first barrier is interposed between the filter member first surface and the housing internal tubular surface adjacent the housing inlet end and a second barrier is interposed between the filter member second surface and the housing internal tubular surface adjacent the housing outlet end. Air flowing into the housing inlet end passes through the filter member before exiting at the outlet end.
Claims20
A filter assembly comprising:
- an impervious elongated tubular housing having an internal substantially circular tubular surface, an inlet end and an outlet end;
- an elongated filter member having opposed first and second surfaces, opposed longitudinal edges, and first and second ends, the filter member being of length not greater than said housing, the filter member being positioned within said housing with said opposed longitudinal edges in contact with and sealably secured to said housing internal tubular surface;
- a first barrier interposed between said filter member first surface and said housing internal tubular surface adjacent said filter member first end;
- and
- a second separate barrier interposed between said filter member second surface and said housing internal tubular surface adjacent said filter member second end.
A filter assembly comprising:
- an elongated hollow housing having an internal substantially circular circumferential surface, an inlet end and an outlet end;
- an elongated filter member having opposed first and second surfaces, opposed longitudinal edges, opposed ends, and of length not greater than said housing, the filter member being positioned within said housing with said longitudinal edges in contact with and sealably secured to said housing internal circumferential surface providing a first and second spaces between said filter member first and second surfaces and said housing internal circumferential surface;
- means for closing said first space adjacent said housing inlet end;
- and
- separate means for closing said second space adjacent said housing outlet end.
A filter assembly comprising:
- an elongated tubular housing having a substantially circular internal tubular surface, an inlet end and an outlet end;
- an elongated filter member positioned within and having opposed longitudinal edges in contact with and sealably secured to said housing internal tubular surface dividing the interior thereof into first and second areas;
- means adjacent said housing inlet end closing said first area;
- and
- separate means adjacent said housing outlet end closing said second area whereby a fluid flowing through said housing from said inlet to said outlet end must pass through said filter member.
A filter assembly comprising:
- an impervious elongated flexible housing having a wall of relative uniform thickness and an internal tubular surface, an inlet end and an outlet end;
- an elongated flexible filter member having opposed first and second surfaces, opposed longitudinal edges and first and second ends, the filter member being of length not greater than said housing, the filter member being positioned within said housing with said opposed longitudinal edges in contact with and sealably secured to said housing internal tubular surface;
- a first barrier interposed between said filter member first surface and said housing internal tubular surface in the direction towards said filter member inlet end;
- and
- a separate second barrier interposed between said filter member second surface and said housing internal tubular surface in the direction towards said filter member outlet end.
