Heating elements (110, 128) are provided within the cyclonic separator (72) to prevent blockage of ice and water discharge ports (118, 78). A mixture of fuel, ice and water is passed from the cyclonic separator (72) and into a reclamation unit (80), in which gravity separates a reclaimed portion of the fuel from the ice and water.

  • Patent number: 5499651
    Abstract: Auto-deicing system with a valve having a butterfly plate (5).The spindle (8) of the valve (4) is controlled by a system terminated by a pin (11) coaxial to the spindle (8) and which, like the latter, has slots (13). When the pin (8) is iced up, the control system initiates a movement of the pin (11) so that the slots (12, 13) come into extension with one another, which allows a circulation of the hot gas on one side of the butterfly plate (5) through the spindle (8), which is thus reheated. The opening movement resumes when the ice has melted.The invention is applicable to cold starting systems on aircraft engines.(FIG.

  • Patent number: 5406798
    Abstract: A main flow divider valve for a main stage of a multi-stage combustor includes a cooling loop for flowing pilot fuel therethrough to remove heat from the main flow divider valve. Various construction details are disclosed which provide cooling of the main flow divider valve during pilot only operation of the multi-stage combustor. In a particular embodiment, the main flow divider valve includes a cooling loop disposed about a housing of the main flow divider valve. The cooling loop has an inlet in fluid communication with a first port of a relief valve and an outlet in fluid communication with the pilot fuel lines. The cooling loop receives a flow of pilot fuel during all operational conditions of the gas turbine engine.

  • Patent number: 4750514
    Abstract: Disclosed is a solenoid valve assembly for use in an fuel injection pump of a motor vehicle basically comprising an electromagnetic actuator section including a stator, a core and a winding and a valve section having a valve for interrupting flow of fuel in a fuel passage. A rod-like member is coupled between the valve and the core and is movable within a guide hole made at the center of the stator so that the movement of the core is transmitted to the valve. The valve is biased by a spring in a direction closing the fuel passage. The valve is actuated to open the fuel passage in response to energization of the winding and is actuated to close the fuel passage in response to deenergization of the winding, the opening degree of the valve being regulated and adjusted by a stopper. The spring and the stopper is provided at a high pressure side of the fuel passage communicating with a compression chamber of the fuel injection pump.

  • Patent number: 4650042
    Abstract: A vibration damping system for vehicles, with a damping element in a cylinder. The cylinder holds a damping medium and is divided into two chambers by a piston. A damping valve, located in a bypass, is connected parallel to the work cylinder. The damping valve variably controls damping to any desired damping in the decompression and compression stages of operation of the vibration damping system. The damping valve has an axially-movable, controllable valve being disposable in an opening. The controllable valve is connected in a series fluid flow relationship with at least one pressure-controlled, spring-loaded valve within the same valve body. The damping valve can be installed in numerous variations in vibration damping systems of vehicles.

  • Patent number: 4630445
    Abstract: The disclosure illustrates a wastegate valve for an internal combustion engine turbocharger comprising a valve head carried by a valve stem and arranged to cooperate with a valve seat in a bypass passage, the valve stem being mounted in a valve guide for movement between a position in which the valve head and valve seat cooperate to close the valve and a position in which the valve head is spaced from the valve seat. A shield formed from a cup shaped thin wall pressing is provided at least partly surrounding the valve stem in a region thereof exposed to heat from the exhaust gases, the shield being disposed so as to deflect hot exhaust gases away from that part of the stem surrounded by the shield. Passageways are provided for conducting a flow of cooling fluid to said valve stem in between a pair of spaced valve guide inserts in at least part of the region surrounded by the shield.

  • Patent number: 4096883
    Abstract: A closed-center controller is disclosed, especially of the type utilized in hydrostatic power steering systems. The controller includes valving which, in the neutral position, defines a bypass passage communicating inlet fluid through the interior of the hollow, primary valve member to the tank port of the controller. The bypass passage includes a variable bypass orifice having a maximum flow area in the neutral position of the valving and decreasing to zero as the valving is displaced from the neutral position. The variable bypass orifice permits the passage of just enough fluid, typically in the range of about 0.25 gpm to about 0.5 gpm, to minimize the temperature difference between the controller valving and the remainder of the hydraulic system, thus minimizing the possibility of thermal seizure of the valving within the controller.
