  • Patent number: 9732678
    Abstract: A system and method for supplementing fuel feed pressure and flow within an aircraft fuel system. The fuel system includes boost and override fuel pumps delivering fuel from the tanks to a fuel manifold, and a jettison fuel pump. The method includes the steps of: (a) sensing whether the aircraft engine is operating near maximum power; (b) upon sensing the condition, operating the jettison fuel pump in fluid interconnection with the override fuel pump to deliver fuel to the fuel manifold; and (c) upon sensing the cessation of the condition, deactivating the jettison fuel pump. The system includes a monitoring circuit signaling when the aircraft engine speed is greater than a predetermined threshold, and a fuel system control circuit operating a jettison fuel pump enable circuit portion in response to the signal while omitting other jettisoning operations. The jettison fuel pump consequently functions as an override fuel pump assist.

  • Publication number: 20150136262
    Abstract: An electrically-controlled water pressure regulator for use with a poultry watering system receives potable water at a first high pressure level and reduces the water pressure level of the water provided to watering valves that dispense water to the flock within a poultry house. A variable control valve uses a needle-shaped cone to engage a round port inside the housing of the regulator. A stepper motor controls the liner movement of the control valve in incremental microsteps to adjust the water pressure level provided to the flock. A feedback component enables the variable control valve to maintain the water pressure level at a desired set point for the flock. The desired set point for the flock is controlled or automated to match the growth of the flock over their growth cycle. An electrical controller and suitable cabling enable multiple regulators to be controlled efficiently and cost-effectively.

  • Patent number: 7673645
    Abstract: The multiple antisymmetric optimal (MAO) control algorithm is disclosed for a gas delivery system including a flow ratio controller for dividing a single mass flow into multiple flow lines. In the MAO control algorithm, each flow line is provided with a flow sensor and a valve actively controlled by a SISO feedback controller combined with a linear saturator to achieve the targeted flow ratio set point. For optimal control performance, these SISO controller and linear saturators are substantial identical. It is proved that each valve control command is multiple antisymmetric to the summation of all other valve control commands. Therefore, the MAO control algorithm guarantees that there exists at least one valve at the allowable maximum open position at any moment, which achieves the optimal solution in terms of the maximum total valve conductance for a given set of flow ratio set points.

  • Patent number: 7059581
    Abstract: A valve for supplying fuel gas to a fuel gas appliance comprises a valve housing which defines a valve chamber within which a main carrier member is axially moveable. The main carrier carries a primary and a secondary valving member for co-operating respectively with a primary and a secondary valve seat. A pilot fluid outlet supplies fuel gas to a pilot jet. A stepper motor comprising a rotor and four magnetic coils urges the main carrier between a fully open and closed position. An electro-magnetic coil located in the main carrier magnetically couples primary and secondary end plates to the main carrier. Magnetic decoupling of the primary and secondary end plates from the main carrier permits the main carrier to be urged into the closed position by primary compression springs. The drive transmission comprises a drive shaft from the rotor of the stepper motor and a drive spindle.

  • Patent number: 6968853
    Abstract: The motor-operated valve for regulating a gas flow is the lift type with a modulating valve cut-off member (11), coupled to a valve spindle (10,10a) sliding linearly along a central gas flow conduit (5). A flame safety valve is open initially due to the pressure of the spindle (10a) and in case of the movement of the spindle being locked because of the change in the direction of rotation of the motor, safety cut-off means (5a, 21-24, 21?-22?) drawn by the spindle (10) are interposed between the valve inlet conduit (6) and the outlet conduits (7,8,20) to prevent gas escaping, while the modulating cut-off member (21,21?) is still not actuated.

  • Patent number: 6957666
    Abstract: Improved low flow impedance flow control valves are disclosed in the present invention wherein spring valve means (12) captured between a valve spool (28) and a shoulder (30) are utilized for selectively metering a flow of fluid from an inlet port (18) to an outlet port (14) via a round edged helical orifice (82) formed between the open coils of the spring valve (12) as a function of the instant axial position of the valve spool (28) and the differential pressure therebetween. An improved method of controlling low impedance flow control valves is also disclosed in the present invention. The improved method provides better accuracy in controlling fluid flow through low flow impedance flow control valves through continually cycling a means for substantially interrupting fluid flow therethrough in a low frequency pulse width modulated fashion.

  • Patent number: 6918408
    Abstract: A valve driving device comprises a main case having one or more inlet pipes through which a fluid flows in from an external compressor and two or more outlet pipes through which the fluid flows out and also having built-in valve elements to open and close openings that are portions of a fluid path for the fluid and are connected to the outlet pipes to flow and stop the fluid and a driving portion for driving the valve elements. When the driving portion is driven in the driving direction, the openings and the valve elements together can switch between four operation modes (close-close, open-close, close-open, and open-open) with respect to the two outlet pipes; three or more of the operation modes, including the close-close mode, being obtained; the driving portion is driven back and forth while two modes of the three or more modes are assigned to be at both ends of the driving direction; and the close-close mode is assigned to be at one of the ends.

  • Patent number: 6874533
    Abstract: A 3/2 normally closed module includes a main body, a housing and a magnetically energizable coil. The main body includes a bore, an armature and a rod. The housing includes first and second valve seats and is configured to receive a first and second ball. The housing also includes a first, a second and a third port. When the module is in an energized state, current flows through the coil, generating a magnetic field. The magnetic field forces the armature against the rod, which in turn, forces the first ball to engage the first valve seat. As the first ball engages the first valve seat, the first ball forces the second ball to disengage from the second valve seat. As a result, a fluid flow path is created between the first and second ports. When the module is in a de-energized state, a spring, disposed between the main body and the second ball, forces the second ball to engage with the second valve seat.

  • Patent number: 6776240
    Abstract: A valve for downhole well service, having a rotary indexer carrying an elastically-loaded valve element on a valve seat surface in a flow passage, the valve element adapted to obstruct one or more flow passages in the valve seat surface when aligned therewith. The valve may additionally, or alternatively, comprise an elastically-loaded valve element mounted in one or more flow passages in the valve seat surface, this valve element adapted to obstruct the flow passage in which it is installed when urged into contact with the valve seat surface. When a valve element is mounted in one or more of the flow passages in the valve seat, the indexer comprises a protrusion positioned to engage such valve element and force it out of contact with the valve seat surface. The valve may be actuated by command from the surface by sending telemetry elements to a downhole telemetry data detector.
