| 20110272340 | FILTER ASSEMBLY AND FILTER ELEMENT - A filter assembly includes a header, a bowl and a replaceable filter element. The bowl is indexed to have a single installed orientation with respect to the header. The filter element is keyed and indexed to both the bowl and the header, with index structures on the filter element engaging complementary coding structures on both the bowl and the header to define a single installed orientation of the filter element with respect to the filter assembly. The filter element lower end cap includes a notch and the filer media defines a longitudinal channel corresponding in position and configuration to the notch in the lower end cap. The lower end cap and channel in the filter media engage a protrusion inside the bowl. The bowl maintains angular orientation (prevents twisting) of the upper and lower end caps when the filter media is exposed to high differential pressures. | 11-10-2011 |
| 20100314470 | Injector having swirl structure downstream of valve seat - An atomizing injector comprises a body having a central bore with a valve situated in the bore, leading to a chamber. An actuator moves the valve between closed condition and open conditions, selectively exposing the chamber to a flow of pressurized liquid. A discharge port extends from the chamber to a discharge orifice. A swirl element is situated in the chamber, while leaving a free space in the chamber immediately above the discharge port. When the valve is opened, liquid flows into the chamber, through the swirl element into the space, forming a whirl in the space before passing through the discharge port and exiting the discharge orifice as an atomized whirling spray. | 12-16-2010 |
| 20100313553 | Integrated pump and injector for exhaust after treatment - A urea solution injection system and an injector with which urea solution or other exhaust treatment liquid from a source tank can be injected as an atomized spray into an exhaust pipe. A metering pump with integrated injection nozzle are contained in a common housing mounted directly to the exhaust pipe, thereby eliminating the separate electric motor driven pump, line between pump, and injector in conventional systems. | 12-16-2010 |
| 20090208355 | Radial piston fuel supply pump - A high pressure radial piston fuel pump is featured having an hydraulic head with two individual radial pumping pistons and associated pumping chambers, annularly spaced around a cavity in the head where a rotating eccentric drive member with associated actuation ring are situated. A rolling interaction is provided between the actuation ring and the inner ends of the pistons for intermittent actuation. Relative rotation is provided between the actuation ring and the drive member. Each piston has a piston bore that has a centerline that intersects the actuation ring but is offset (X) from the drive axis as viewed in cross section perpendicularly to the drive axis and the piston bore centerlines are parallel to each other but offset (Y) from each other as viewed in longitudinal section along the drive axis. | 08-20-2009 |
