Patent number: 8852443Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.Type: GrantFiled: September 12, 2007Date of Patent: October 7, 2014Assignee: Cummins Filtration IP, Inc.Inventors: Todd Forrest, J. Bruce Schelkopf, Ted S. Loftis, Barry Verdegan, Wassem Abdalla, Mark Wieczorek, Gérard Malgorn, Charles W. Hawkins, Chad Thomas, Joe Saxon, Mark Johnson, Naren Shaam

Publication number: 20060283815Abstract: An apparatus, system, and method for fluid filtering with contaminant removal, such as removing water from the surface of a top loading-type fuel filter element, includes a housing containing a cavity, a fluid flow inlet leading into the cavity, a filter element disposed in the cavity, and a flow director configured to direct the flow of fluid against the filter element such that contaminant collected on the surface of the filter element is sloughed off. The flow director may be configured to direct the fluid flow at least partially parallel to the filter element. The flow director may further be configured as one or more holes in a filter element housing disposed around the filter element.Type: ApplicationFiled: June 19, 2006Publication date: December 21, 2006Inventor: Mark Wieczorek

Publication number: 20060086649Abstract: A fuel water separator system includes a fuel tank for storing fuel and a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator. The fuel pump has a high pressure side where the fuel has a higher pressure than at the suction side. A water pump, such as a venturi or a jet pump, is fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank. The water pump is fluidly coupled to the high pressure side of the fuel pump to receive the fuel at the higher pressure to drive the water pump.Type: ApplicationFiled: October 26, 2004Publication date: April 27, 2006Inventors: Mark Wieczorek, Peter Herman, Ricky England, Jean-Yves Picard, Benoit Le Roux, Jean-Luc Guichaoua

Publication number: 20060053756Abstract: A filter system includes a filter configured to regulate fuel pressure as well as automatically vent air from the filter. A pressure regulator valve is positioned in the top of a standpipe of the filter. The filter includes a filter cartridge with top and bottom end caps. The top end cap of the filter cartridge has a hole with radial sealing gasket, which seals against the top of the standpipe to prohibit flow from bypassing the filter cartridge. This arrangement exposes the regulator valve to the fuel and/or air at the top of the filter housing. Pressure in the housing opens the valve, allowing air and/or fuel to be vented through the standpipe, and back to the fuel tank.Type: ApplicationFiled: September 14, 2005Publication date: March 16, 2006Inventors: Charles Hawkins, Mark Wieczorek, Clinton DeWeese, Ricky England

Publication number: 20050155427Abstract: A fluid level detector system, which may measure the amount of fluid in a reservoir, and may further trigger an alarm when the fluid level in the cassette reaches a low level condition. The cassette's reservoir may contain a transient sterile solution, which is moving through the cassette to be either cooled or heated in the heat exchanger area. The detection scheme includes a ring magnet housed in a float assembly located in the fluid reservoir of the cassette and, e.g., two magnetic sensors, such as may form a Hall effect integrated circuit, which may be fixed within the console.Type: ApplicationFiled: November 18, 2004Publication date: July 21, 2005Inventors: Michael Magers, Adib Daoud, Mark Wieczorek

Publication number: 20050084256Abstract: A fuel filter housing and fuel heater combination for a fuel-water separator includes, as part of the fuel filter housing, a heater-receiving bore and a protrusion adjacent the heater-receiving bore. The fuel heater is constructed and arranged for inserting into the bore and includes a flange that is attached to the housing for securing the fuel heater in position. The fuel heater includes a notch that is constructed and arranged with a ramp portion. With the fuel heater properly seated, the protrusion inserts into the notch and is seated against the ramp portion. O-ring seal swelling may cause the fuel heater to be difficult to remove and the protrusion cooperates with the ramp portion by way of a camming action to facilitate removal of the fuel heater from the bore under such conditions.Type: ApplicationFiled: September 3, 2004Publication date: April 21, 2005Inventor: Mark Wieczorek
