International Classification:

B05B 130

US Classification:

2395851, 2395332, 4272497, 42724915, 427490, 427577

Abstract:

An electromagnetic fuel injector having improved wear characteristics comprises a body having a fuel inlet and a fuel outlet. A valve seat is sealably connected to the body, and a moveable valve member positioned at the fuel outlet for controlling the flow of fuel from the outlet comprises a valve outlet element that provides a sealing interface with the valve seat. The valve member and included valve outlet element further comprise wear surfaces that are subject to repeated impact and/or sliding contact; at least a portion of these wear surfaces comprise an applied layer of diamond-like carbon (DLC) stabilized by inclusion of greater than 30 weight percent of a carbide-forming material selected from the group consisting of silicon, titanium, and tungsten.

International Classification:

F02M 3704

US Classification:

123541

Abstract:

A liquid cooled fuel rail assembly includes an elongate tubular fuel conduit having a longitudinal central axis and a first diameter. The fuel conduit is configured for carrying fuel and defines at least one port, each port being configured to receive an intake end of a corresponding fuel injector. A first end plug is associated with a first end of the fuel conduit and defines a first bore and a second bore therethrough. The first end plug seals the first end of the fuel conduit. A second end plug is associated with a second end of the fuel conduit and defines a first bore and a second bore therethrough. The second end plug seals the second end of the fuel conduit. A fuel inlet is in fluid communication with the second bore of the first end plug. A fuel outlet is in fluid communication with the second bore of the second end plug. An elongate tubular coolant conduit has a second outside diameter that is less than the first outside diameter of the fuel conduit.

International Classification:

F02M 6108
F16K 5100

US Classification:

2395337

Abstract:

A fuel injection system is disclosed having a fuel injection nozzle which receives pressurized fuel pulses from a source. The nozzle includes a body having a tubular nozzle body with a longitudinally extending opening extending therethrough. A valve seat is located between the upstream and downstream ends of the longitudinal opening in the valve body for engagement with a valve member to thereby regulate the flow of fuel through the opening. A downstream stop member includes a hollow cylinder with a diametrical member extending across one end. The cylindrical stop member is received over the downstream end of the nozzle body with the diametrically extending member disposed across the downstream end of the longitudinal opening to thereby limit the outward range of movement of the valve member from the opening. As a result, the valve member and the downstream end of the longitudinally extending opening define an annular fuel metering orifice therebetween to regulate the flow of fuel from the nozzle.

Abstract:

A high pressure hydraulic diaphragm pump having a pressure chamber on one side of a diaphragm and a fluid delivery chamber on the other side of the diaphragm with a reciprocating piston assembly including a piston member being provided for pressurizing the hydraulic fluid in the pressure chamber and having the pressure chamber connected with a pressure regulator which maintains the desired discharge pressure of the fluid and in which the piston assembly is combined with a diaphragm positioning mechanism for maintaining the diaphragm at a desired position relative to the piston member so as to assure full stroke of the diaphragm during normal operation of the pump.
