摘要： 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.

摘要： 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.

摘要： 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 rigid, relatively thick 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.

摘要： A fuel injector having a tubular debris shield diverter (62) mounted in a high pressure flow passage (30) within the fuel injector. The tubular debris shield diverter (62) provides the dual functions of passing the main flow of high pressure fuel with large debris particles to relatively large discharge openings, such as the injector spray holes (22), while allowing some high pressure fuel to flow through a multitude of very small transverse holes (62) to a sensitive hydraulic component, such an injector control valve circuit (52,54). In one embodiment, the tube (62) has a wall thickness in the range of about 0.1 to 0.5 mm and at least about 2000 holes with a diameter in the range of about 20 to 30 microns.
