Patent application numberDescriptionPublished
20080203614Method for Making Filter Element - A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally molded seal is provided.08-28-2008
20080276580Oil Mist Removal Device with Oil Fill - An oil mist removal device, with oil fill, is provided for an internal combustion engine. A housing has first and second passages, and a separator therebetween. An oil fill port in the first passage is provided for adding oil to the engine.11-13-2008
20090120854Inertial Gas-Liquid Separator with Valve and Variable Flow Actuator - A self-governing continuously variable inertial gas-liquid separator has an axially movable valve controlling axial flow through a nozzle orifice, and a variable flow controller upstream of and controlling the valve.05-14-2009
20090126324Authorized Filter Servicing and Replacement - A method is provided for servicing a filter, and structure is provided disabling assembly of the filter unless an authorized replacement filter element is used.05-21-2009
20090193770Gas-Liquid Separator with Expansion Transition Flow - A gas-liquid separator assembly has a flow passage providing expansion of and reduced flow velocity of the post-separation gas stream, and in some embodiments provides pre-escape regions facilitating partial pre-transition of some of the flow.08-06-2009
20100077710Filter Assembly with Sealed Windowed Flow Path - A filter assembly includes a laterally extending filter element having an element plate extending laterally outwardly therefrom and mounted between axially spaced first and second housing shells. First and second sets of one or more windows are formed axially through the element plate and define a flow path through the assembly.04-01-2010
20100101425Inertial Gas-Liquid Separator with Axially Variable Orifice Area - An inertial gas-liquid separator removes liquid particles from a gas-liquid stream and has a variable orifice area variable along an axial direction and dependent upon axial movement of a plunger relative to a housing sleeve.04-29-2010
20110113737Combination Relief Valve and Drainage Mechanism Requiring Inserted Element to Permit Drainage in a Coalescer System - Disclosed are coalescer systems for coalescing a liquid phase dispersed in a gas phase. The disclosed systems include a filter element which, when installed in the system, contacts and moves a valve to an open drainage position to permit flow of liquid through the system. In the disclosed systems, the filter element and valve also are configured such that under excess pressure conditions the valve permits the gas phase to bypass filter media of the filter element. In particular, the disclosed coalescer systems may be utilized in a CV system in order to remove oil mist from gas in the CV system.05-19-2011
