Appl. No.:

10/624385

Inventors:

Justin Darnell - Southaven MS, US

International Classification:

B01D045/00

US Classification:

055/319000, 055/385300, 055/423000, 055/392000

Abstract:

A water separator is formed in two pieces, one of which is unitary (in one piece) with the intake air scoop, and the other of which is unitary (in one piece) with the air cleaner housing, or cowl therefore. An inlet scoop piece includes an enlarged rib defining an internal enlarged channel. A drain tube extends downwardly from the annular rib. An outlet scoop piece includes an internal lip, projecting co-axial with the body of the water separator. The inlet scoop piece alternatively can include both the enlarged rib portion and the internal lip. The outlet scoop piece has a forward-facing receiving channel, outwardly surrounding the lip, which receives a forward facing mouth of the inlet scoop to properly align the inlet scoop with the outlet scoop. Attachment flanges are provided on each piece to connect the inlet scoop with the outlet scoop.

International Classification:

B01D 35/02

US Classification:

210459000, 210450000, 210462000, 210463000

Abstract:

A flat panel filter to filter air flowing in an inline fluid duct system as an air supply system for an engine or the like includes a housing configured as a section of an inline fluid flow duct of an inline fluid duct system, the housing having a flow path including a fluid inlet to receive air flow from an inlet fluid duct portion of such inline fluid duct system and a fluid outlet to provide air flow to an outlet fluid duct portion of such inline fluid duct system, a filter in the housing, and a connector configured to connect the housing as an inline fluid flow section of such inline fluid duct system between such inlet fluid duct portion and outlet fluid duct portion of such an inline fluid duct system, the connector including a number of hook-like fingers of the housing, respectively, at least proximate a respective fluid inlet and fluid outlet of the housing to provide a sliding relation and resiliently biased connection with respective inlet and outlet fluid duct portions of such inline fluid duct system. Detents resist sliding of the hook-like fingers relative to the inlet and outlet duct portions; a lock is selectively operable to lock or to unlock connection between the flat panel filter and the inlet and outlet duct portions; and a gasket seals the connection between the flat panel filter and the inlet and outlet duct portions.

International Classification:

B01D 35/14

US Classification:

210100

Abstract:

A filter cartridge includes a fuse element () that closes an exit door () when an inlet-outlet pressure differential rises to a range corresponding to a clogged filter media. The fuse element () comprises a plastic poppet () that remains staged on a podium () during normal operation. An increase in inlet pressure and/or a decrease in outlet pressure pushes the poppet () away from the podium () and positions it to seal the exit door ().
