Abstract: A damper assembly for a fuel pump includes at least one diaphragm assembly formed by joining two metal diaphragms to respective two sides of an imperforate central plate, thereby creating a pair of closely spaced diaphragms, each acting upon its own gas volume. Preferably, the diaphragm assembly has (a) a circular or polygonal central plate, (b) a first circular diaphragm having a rim portion sealingly secured as by welding to the plate and a relatively thin, flexible, convex portion projecting from one side of the plate and defining a first pressurized gas volume, and (c) a second circular diaphragm having a rim portion sealingly secured as by welding to the plate and a relatively thin, flexible, convex portion projecting from the other side of the plate and defining an independent second pressurized gas volume. The diaphragm assembly can be supported radially inside, outside, or on the weld.

Abstract: 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.

Abstract: A high pressure piston fuel pump having a discharge check valve between the pumping chamber and a pressurized fuel reservoir and a pressure relief valve between the fuel reservoir and a passageway in the housing, wherein the discharge check valve and the pressure relief valve are contained within a single fitting assembly affixed at the pump housing. A first end flow passage is in fluid communication with the pumping chamber and provides an inlet to the discharge check valve and an outlet from the pressure relief valve. A second end flow passage is in fluid communication with the fuel reservoir and provides an outlet for the discharge check valve and an inlet for the pressure relief valve. Advantages include the ability to pre-test the outlet check and pressure relief prior to assembly into the pump housing, and improved flexibility of the outlet fitting location.

Abstract: 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.
