  • Patent number: 4033112
    Abstract: Fuel control apparatus including a fuel conduit connected to receive pressurized fuel from a fuel pump and provided with fuel servo actuated metering valve means therein for controlling the rate of fuel flow therethrough to an engine. The fuel servo actuated metering valve is actuated by a fuel servo piston pressurized by a servo valve controlled fuel pressure differential derived from a predetermined fuel pressure differential maintained by a pressurizing valve downstream from and in series flow relationship with the metering valve. The metered fuel flow for actuating the servo piston is extracted from the fuel conduit upstream from the pressurizing valve and returned to the fuel conduit downstream from the pressurizing valve.

  • Patent number: 4033116
    Abstract: Fuel distribution apparatus comprising a jet and two valves arranged in parallel in a passage connecting the fuel delivery line to the main manifold. The first valve maintains a predetermined pilot manifold pressure required for steady combustion of the fuel delivered through the pilot manifold. The second valve has a flow area greater than that of the jet and the first valve. When engine speed is reached at which the combustion of the fuel delivered through the main manifold becomes steady, the second valve opens and allows fuel to flow therethrough, effectively bypassing the jet and the first valve.

  • Patent number: 4031864
    Abstract: A multiple fuel supply or an internal combustion engine wherein phase separation of components is deliberately induced. The resulting separation permits the use of a single fuel tank to supply components of either or both phases to the engine. Specifically, phase separation of a gasoline/methanol blend is induced by the addition of a minor amount of water sufficient to guarantee separation into an upper gasoline phase and a lower methanol/water phase. A single fuel tank holds the two-phase liquid with separate fuel pickups and separate level indicators for each phase. Either gasoline or methanol, or both, can be supplied to the engine as required by predetermined parameters. A fuel supply system for a phase-separated multiple fuel supply contained in a single fuel tank is described.

  • Patent number: 4031773
    Abstract: A device for actuating a sheathed control cable comprises a push button wh is movable to apply a tension to the cable. An inclined surface rigid with the push button engages, via a ball, a traction member anchored to the cable. When the button is depressed the inclined surface displaces the traction member via the ball whereby the cable is tensioned. The ball rolls along the inclined surface during this movement whereby such movement occurs substantially without friction.

  • Patent number: 4027472
    Abstract: This invention relates to fuel controls for turbine types of power plants and to the means for resetting the idle speed and stator vanes from a single point contact. In one embodiment, fuel flow is reset by changing the hydraulic forces on the throttle valve and its control system which serves to provide a W.sub.f /P.sub.3 .times. P.sub.3 control function, where W.sub.f = fuel flow in pounds per hour and P.sub.3 = compressor discharge pressure in pounds per square inch absolute. The profile of the 3-D cam utilized to control the stator vanes is also utilized to set the droop schedule of the idle speed setting controlled by the fuel control.
