  • Patent number: 11922820
    Abstract: A communication system includes a traffic relay (TR) device for locating unmanned traffic in a controlled airspace. The TR device comprises one or more processors configured to perform the step of receive a status message from an unmanned aerial vehicle (UAV). The status message provides identification and location information of the UAV. The one or more processors are also configured to perform the step of generate a warning message for communication to at least one manned aerial vehicle (MAV) or a manned traffic manager (MTM) device that is communicatively connected to the at least one MAV. The warning message is based on a comparison of the location of the UAV to a designated airspace.

  • Patent number: 7690353
    Abstract: Noise and vibrations associated with a common rail fuel system drive linkage are reduced by synchronizing a high pressure common rail supply pump with engine operation. This may be accomplished by selecting a linkage associated with a desired ratio of engine speed to pump speed along with selecting a number of pump plungers and cam lobes that results in synchronizing action of the pump with engine combustion events. In particular, a pattern of pumping events per engine cycle repeats during each engine cycle. In a more sophisticated version, the pattern of pumping events per engine cycle includes a sub-pattern of pumping events that repeats an integer number of times each engine cycle, where the integer number equals the number of engine cylinders.

  • Publication number: 20070175448
    Abstract: A system for selectively intensifying fuel for injection utilizing a fuel injector having an intensifier piston connected to a drain and a pressurized fuel source. The intensifier piston includes a control chamber co-axially positioned opposite from an intensification chamber, and a pressurization chamber co-axially positioned between the control chamber and the intensification chamber. The control chamber selectively fluidly communicates with the pressurized fuel source and the drain. The intensification chamber fluidly communicates with the pressurized fuel source and the pressurization chamber fluidly communicates with the pressurized fuel source and a nozzle assembly.

  • Publication number: 20070074703
    Abstract: Often there is a limited fuel injector spatial envelope above and within a cylinder head for a fuel injector. In order to fit a fuel injector with a direct control needle valve and a capability of injecting fuel at a rail pressure and an intensified pressure into the limited fuel injector spatial envelope, the present disclosure includes a fuel injection system in which a pressure intensifier and nozzle outlets of a fuel injector are fluidly connected to a source of fuel via an intensifier line and an injector line, respectively. The flow of fuel to the pressure intensifier is controlled via a valve attached to the source of fuel.

  • Publication number: 20060009294
    Abstract: In order to prevent damage to a drive component, fail safe devices are often used to break a rotational coupling between an apparatus, such as a pump, and the drive component, such as a crank shaft of an engine, in the event of the apparatus seizing. In order to break the coupling between a drive component and an apparatus, the rotational coupling includes a coupler that is operable to rotate in a first direction attached to a shaft via a threaded fastener. A predetermined break away torque is set by tightening the threaded fastener in a direction opposite than the first direction with a predetermined tightening torque. A torque transmission interface includes opposing surfaces of the coupler and the shaft that remain fixed relative to one another below a predetermined break away torque and move relative to one another above the predetermined break away torque.

  • Publication number: 20050150972
    Abstract: A fuel injector includes an auxiliary valve member that can assist in raising a mean injection pressure, increase a nozzle valve opening pressure, and hasten the closure rate of a nozzle valve member over an equivalent fuel injector without the auxiliary valve. The auxiliary valve member is fluidly positioned between a needle control chamber and a high pressure space, which includes a fuel pressurization chamber within the fuel injector. The auxiliary valve member includes a closing hydraulic surface exposed to fluid pressure in the high pressure space. The plumbing and the auxiliary valve member allow high pressure fuel to act upon a closing hydraulic surface of the nozzle valve member to increase valve opening pressure and mean injection pressure. The needle control chamber may be vented or may be a closed volume when the auxiliary valve member is in its closed position.

    Abstract: A valve has a housing defining an interior of the valve. The valve has a first passage in the housing and a second passage in the housing. The valve has a flow limiter movable between a first position at which the first passage is in fluid communication with the second passage and a second position at which the first passage is not in fluid communication with the second passage. The valve has a flow restriction device movable between a first position at which a first flow rate is permitted into the interior of the valve and a second position at which a second flow rate is permitted out of the interior of the valve. The first flow rate is greater than the second flow rate.
