Patent number: 7794525Abstract: An apparatus and a system is provided that may be utilized to provide stability to air flow through a hood scoop. The present invention may also be utilized to straighten and smooth out air flow through a hood scoop and accompanying air filter media. The present invention utilizes an air filtration media which may be inserted into at least a portion of a vehicle hood scoop and may filter out particulate and may also slow air flow down temporarily in order to straighten and/or smooth turbulent air flow through the air filtration media. Additionally, the present invention may provide an apparatus that may facilitate more uniform pressure inside the hood scoop of the vehicle.Type: GrantFiled: August 20, 2007Date of Patent: September 14, 2010Assignee: K&N Engineering, Inc.Inventor: Jonathan Richard Fiello

Publication number: 20100223894Abstract: An air cleaner suitable for use with a heavy-duty vehicle includes a cylindrical body that can be mounted to the vehicle so that the body is exposed to an air stream when the vehicle moves in a forward direction. The air cleaner has a boattail, which includes a fin attached to a rear portion of the body. The fin has a vertical orientation and extends in a substantially rearward direction from the body. When the vehicle moves in a forward direction, the boattail reduces the amount of low-pressure air located behind the air cleaner.Type: ApplicationFiled: March 6, 2009Publication date: September 9, 2010Applicant: PACCAR INCInventor: Jeffrey P. Smith

Patent number: 7789925Abstract: A purge exhaust processor includes an inlet chamber receiving a purge exhaust. A portion of the purge exhaust including at least one of moisture, air, and oil is passed from the inlet chamber to a sump volume. A heat source changes a phase of the moisture from liquid to gas. A wick transfers the oil from the sump volume to an oil collector.Type: GrantFiled: February 12, 2010Date of Patent: September 7, 2010Assignee: Bendix Commercial Vehicle Systems LLCInventors: William P. Fornof, Fred Hoffman, Leonard A. Quinn, Randall W Nichols

Publication number: 20100218466Abstract: A vehicle filter assembly includes a housing, a cyclone-inducing structure and a self-cleaning trap mechanism. The housing has an inlet, an outlet and a trap aperture. The cyclone-inducing structure is disposed within the housing between the inlet and the outlet to separate particulate from gases passing through the housing from the inlet to the outlet. The self-cleaning trap mechanism is movably arranged with respect to the trap aperture to move between a closed orientation sealing the trap aperture and an opened orientation exposing the trap aperture to release particulate from the housing.Type: ApplicationFiled: February 27, 2009Publication date: September 2, 2010Applicant: NISSAN TECHNICAL CENTER NORTH AMERICA, INC.Inventor: Robert Lloyd

Patent number: 7776119Abstract: A self cleaning filter for a small internal combustion engine (1) is disclosed. The filter (16, 36, 46) is generally rectangular and is located closely adjacent the air exit region of the engine's fan (2). The longitudinal axis of the filter is generally aligned with the direction of air flow. The filter can be flat (16), curved (36) or inclined towards the air flow (46). The arrangement permits a more compact configuration for the engine (1).Type: GrantFiled: February 2, 2005Date of Patent: August 17, 2010Inventors: John A. Notaras, Angelo L. Notaras

Patent number: 7776118Abstract: The present invention relates to a cap for hermetically sealing receiver driers, in which a cap body and a filter are separated and detachably engaged with each other and an O-ring is installed between the cap body and the filter, thereby facilitating the replacement of parts and the installation of the O-ring, favoring automatic assembly due to a tool insertion groove that can be formed long, achieving compactness of the cap due to the reduction of a total height of the cap when the cap body and the filter are engaged, improving a filtering effect by increasing the size of the filter with the cap being maintained in the same size, and facilitating engagement between the cap body and the filter and preventing the cap body from being released from a tank by discharging the air between the cap body and the filter.Type: GrantFiled: August 8, 2005Date of Patent: August 17, 2010Assignee: Halla Climate Control CorporationInventors: Eunki Min, Junil Jang, Hyongnyol Kim, Youngsung Lee, Goangsik Min, Seongkyun Byeon, Junyoung Shin
