Slots are left clear in the wire profile through which a fluid may pass. The wire profile is, at least in part, rigidly connected to the support rods and is enclosed in a screen grid. The screen grid, at least in part, rests against the wire profile, follows to the same extent the conical path of the filter element, and is provided on its ends with end components. Since the conical screen grid is in the form of a one-piece pull-on part fitted on the support structure and since the pull-on part is designed to be longer than the support structure, after the screen grid has been pulled onto the support structure, at least one projecting length of the screen grid may be separated for precision fitting and is connected to the respective end component of the filter element.Type: GrantFiled: May 1, 2003Date of Patent: January 4, 2005Assignee: HYDAC Process Technology GmbHInventors: Ralf Wnuk, Martin Winter, Norbert Lang

Patent number: 6808552Abstract: Filtration method and device for filtering solid contaminants from a stream of a flowing fluid such as internal combustion engine intake air. An imperforate housing has a tubular inlet exiting at its downstream end into a conically divergent first wall section terminating in a maximum diameter apex. A convergent second wall section terminates at a housing outlet opening of greater diameter than that of the housing inlet. A perforate filter element disposed within the housing conical portions has an exterior configuration generally complimental to the housing interior, and thus has a first generally conical divergent section, and a second generally conical downstream section convergent from a maximum diameter apex of the filter element and defining the filter device outlet. The housing and filter element define therebetween first and second frustoconical annular fluid flow chambers of successively diminishing cross-sectional radial thickness in the direction of downstream fluid flow.Type: GrantFiled: October 15, 2002Date of Patent: October 26, 2004Assignee: Borla Perfomance Industries, Inc.Inventor: Alexander Borla

Patent number: 6739460Abstract: A non-contaminating paint strainer is comprised of a conical receptacle having a conical tapering side wall. The side wall has an inner surface and an outer surface. The conical receptacle defines a lower filtration portion having an aperture provided with reinforcing ribs formed integral with the side wall and extending into the aperture. A filtration mesh screen is secured to the outer surface of the tapering side wall adjacent the aperture and to an outer surface of the reinforcing ribs by glue applied solely to the outer surface of the side wall and outer surface of the reinforcing rib, whereby paint being filtered by the conical receptacle will be in contact solely with the inner surface, free of the glue. Any ink printing is provided on the outer surface of the conical side wall above the mesh screen.Type: GrantFiled: May 15, 2002Date of Patent: May 25, 2004Assignee: Arslan Automotive Canada Ltd.Inventor: Arman Gurarslan

Patent number: 6722508Abstract: A one-piece filter cartridge is formed by inserting an open ended cylindrical screen and an end screen for the cylindrical screen in a mold and overmolding with engineered resinous material to form spaced annular and axial support ribs for the screen material. The cartridge is suitable for use in an hydraulic circuit for filtering bi-directional and radial flow without backwashing trapped particles from flow in one axial direction. One of the ribs has an annular groove for a seal ring for sealing about the cartridge upon insertion in a flow passage.Type: GrantFiled: May 15, 2002Date of Patent: April 20, 2004Assignee: Eaton CorporationInventors: Kenneth J. Parker, Jorge A. Moreno, Chuck Chang, William J. Gorski, Jr.

Publication number: 20040031747Abstract: A fluid filtering system for filtering dirt and other debris from fluids being conveyed in a pipeline for snow making apparatus and other devices. An upright pipe segment is connected to a horizontal pipe segment through a pipe elbow or angle for conveying fluid such as water and/or air under pressure from the horizontal pipe segment through the pipe angle and upwardly through the upright pipe segment. A filter is provided in the upright pipe segment adjacent its lower end and an external drain is disposed in the pipe angle directly under the filter to automatically flush and clean the filter when the drain is opened.Type: ApplicationFiled: August 14, 2002Publication date: February 19, 2004Inventor: Herman K. Dupre

Patent number: 6692639Abstract: A conically shaped filtration and/or separation apparatus is provided which is constructed from a stack of filters at least some of which are different sizes superposed above each, other, of said plurality of said filters in a fluid communicable relationship. A collapsible version of such conically shaped filter and/or separation apparatus is provided whereby a plurality of such filters are connected together using two piece interlocking or connecting end caps.Type: GrantFiled: April 15, 1999Date of Patent: February 17, 2004Assignee: Porous Media CorporationInventors: Patrick R. Spearman, Michael R. Spearman, Majid Zia
