Patent number: 7900854Abstract: A filter for use with overhead sprinkler irrigation systems is disclosed. The filter includes a hollow cylindrical body, a removable screen, and a manually-actuated plunger adjacent the screen. The plunger is positioned for reciprocal movement through a debris outlet between an open, debris-discharging position, and a closed filtering position. The plunger defaults to the closed filtering position by pressurized water flowing through the body. The water is simultaneously filtered through the screen and passes out a clean water outlet while debris accumulates within the body. The plunger may be manually retracted to the open, debris-discharging position at any time, whereby accumulated debris is flushed out of the body through the debris outlet by residual water flowing therethrough.Type: GrantFiled: April 9, 2007Date of Patent: March 8, 2011Assignee: American Agriculture Products, LLCInventor: Gerald Beer

Patent number: 7891587Abstract: The invention relates to an intermediate plate for a fuel injector, comprising a high-pressure through-hole which connects a high-pressure passage in a valve body and is connected to a high-pressure fuel reservoir, to a high-pressure space in a nozzle body, wherein the intermediate plate is arranged between the valve body and the nozzle body. In order to improve the injection behaviour of a fuel injector provided with the intermediate plate, in particular during multiple injection of small injection quantities, the high-pressure through-hole has a cross-sectional profile which improves the flow through the high-pressure through-hole from the valve body towards the nozzle body and impairs the flow in the opposite direction from the nozzle body towards the valve body.Type: GrantFiled: October 9, 2006Date of Patent: February 22, 2011Assignee: Robert Bosch GmbHInventor: Patrick Mattes

Patent number: 7878426Abstract: A sanitary outlet unit (1) is provided, including an outlet armature (2), with a flow regulator (4) in a region of the water outlet (3) thereof, wherein an aeration device is provided for aeration of the water flow. The outlet unit (1) provides that the aeration unit (5) is located in the outlet armature (2) and/or in at least one water line leading to the outlet armature (2) separately from the flow regulator (4). Through the spatial separation of the functions of flow shaping or water discharge and the aeration of the water flow, there are many possible embodiments for optionally providing the water outlet (3) of the sanitary outlet unit (1) with an extremely thin design.Type: GrantFiled: January 19, 2006Date of Patent: February 1, 2011Assignee: Neoperl GmbHInventor: Oliver Denzler

Patent number: 7878427Abstract: An injector having an injector body to which a fuel line is connected for delivering fuel at high pressure. A filter bore is formed in the body and a fuel filter is disposed, through which filter the delivered fuel flows. A sealing seat is formed in the filter bore against which seat the end of the fuel line is pressed upon fastening of the fuel line to the injector body. The filter bore discharges at the outside of the injector body. The sealing seat is disposed with its longitudinal axis inclined to the longitudinal axis of the filter bore, and in the injector body, a bore extending at least approximately coaxially to the sealing seat is provided, into which the end region of the fuel line plunges. By the end region, plunging into the bore, of the fuel line, an outer end region of the filter bore, discharging at the outside of the injector body, is separated from an inner end region, subjected to high pressure, of the filter bore, and the fuel filter is disposed in the inner end region of the filter bore.Type: GrantFiled: July 18, 2005Date of Patent: February 1, 2011Assignee: Robert Bosch GmbHInventor: Andreas Wengert

Publication number: 20110011955Abstract: A fuel injector that comprises a parallel circuit fuel filtration circuit providing filtered fuel to the control valve. Specifically, a fuel filter is positioned inside the injector within the passage leading to the control valve. Debris is removed from the fuel and filtered fuel is allowed to pass through to the control valve. Unfiltered fuel may be purged from the fuel injector during injection. Alternatively, unfiltered fuel may be removed from the injector via the drain.Type: ApplicationFiled: July 20, 2009Publication date: January 20, 2011Applicant: Caterpillar Inc.Inventor: Bryan D.

Publication number: 20110006136Abstract: A lower fuel injector filter includes a generally planar disk having an annular shape and including a plurality of filter holes. The disk is retained by a valve guide within a valve seat. The disk prevents internally generated contamination particles contained in fuel flowing through the filter holes from reaching a valve and seat interface positioned downstream of the valve guide. The disk may also be retained by a ball valve stop proximate the valve seat.Type: ApplicationFiled: July 7, 2009Publication date: January 13, 2011Inventors: Vicki A. Flynn, Stefan O. Fedunyszyn, Dominic N. Dalo, Paul A. Wheeler, Otto Muller-Girard, JR., Cynthia J. Baron

Patent number: 7866576Abstract: A combination shower arm and water filter having an integrated design for attachment between a water pipe behind a shower wall and a showerhead. The combination shower arm and water filter including a body having a first hollow arm and a second hollow arm connected to a central cartridge holding portion. The filter holding portion has a central opening with a filter cartridge or element removably held in a hollow chamber formed above the filter holding portion by means of a cap that is removably secured to the an upwardly extending annular portion formed on the filter holding portion. Water entering the combined shower arm and filter assembly through the first hollow arm is directed into the hollow chamber for passage through filter media in the filter cartridge or element before it exits through the second hollow arm and out a showerhead.Type: GrantFiled: March 7, 2006Date of Patent: January 11, 2011Inventor: David K. Farley
