Embodiment Construction

[0053] The following description is merely exemplary in nature and is not intended to limit the disclosure, application, or uses.

[0054] refer to figure 1, shown and indicated generally by reference numeral 10 is an air filter assembly according to the present invention. The air filter assembly 10 is shown mounted on an engine compartment wall 12 of a motor vehicle 14 such as, for example, a passenger car, sport utility vehicle, or light truck. The motor vehicle 14 includes a transmission 16 , which may be manual or automatic and which includes an outlet or vent or fitting 22 generally and preferably located on the top or upper portion of the transmission 16 . A flexible hose or tube 24 communicates between the transmission outlet or vent 22 (and thus the interior of the transmission 16 ) and the air filter assembly 10 . It will be appreciated that the air filter assembly 10 according to the present invention is useful and intended to be used with all ventilated motor vehi...

Abstract

An outside air filter for a vehicle transmission or the like includes a rigid, hollow body that may be spherical, cylindrical, rectangular, or shaped to fit the available, typically hood, space. If spherical, it may be assembled from a first lower hemisphere and a second upper hemisphere about their edges by, for example, a press fit or interference fit (received in complementary edge-adjacent channels). o-rings), adhesives or self-bonding. Other shapes and configurations may be assembled from the body with, for example, a solid bottom and an attachable lid, top or lid. The hollow body is filled with activated carbon filter media or passive fiber filter media. The upper hemisphere, cap or cover includes outlets and caps that reduce the likelihood of water being drawn into the filter. The lower hemisphere or body includes an inlet fitting to which a hose leading to an outlet or vent in the powertrain component is attached.

Description

technical field [0001] The present disclosure relates to air filters for motor vehicles, and more particularly, to filters for removing odors from air flowing from a transmission, transfer case, differential, etc. in a motor vehicle. Background technique [0002] The statements in this paragraph merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] With the recent widespread incorporation of air conditioning systems into passenger cars, it is not news that these passenger cars are operated as substantially sealed cabins with the only source of air being the heating, ventilation and air conditioning (HVAC) system. This situation imposes additional costs for supplying the passenger compartment with clean, fresh-smelling air free of any odour, at least from the driver's own vehicle. [0004] Low-viscosity oils, transmission oils, and gear lubricants of increasingly complex composition are accompanied by a curi...
