Flow Path With Serial Valves And/or Closures Patents (Class 137/613)
  • Patent number: 10920934
    Abstract: A mobile dispenser may be used to at least partially fill hydrogen tanks of fuel cell-powered vehicles. The dispenser uses a purely mechanical control of the fill using an orifice plate across which a pressure differential is maintained through use of a backpressure regulator whose reference pressure is controlled by a differential pressure regulator. Because it does need or use electrical power, it may be used in situations where no electrical power is available or convenient.

  • Patent number: 10773045
    Abstract: An anesthesia delivery and ventilation system (ADVS) includes an expiratory section, a circulation flow system (CFS), an inspiratory section, a ventilation drive system (VDS), and an anesthesia delivery system (ADS). The expiratory section receives gases from a patient and the inspiratory section and fresh gases from a fresh gas supply system. An elastic mixing reservoir receives and mixes the gases circulated by the CFS with residual gases via a connector element. The inspiratory section connects to the expiratory section at one end and to a patient connector tube at the other end. The ADS infuses an anesthetic agent into the mixed gases in the inspiratory section. The VDS delivers the mixed gases with the anesthetic agent to the patient. The VDS and the CFS are controlled and operate independently of each other to provide positive end-expiratory pressure control and ventilation control to the patient without use of a proportional valve.

The sections on either side of the barrier may be rated for different pressures, temperatures, and/or flow rates. For example, the first section (upstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a first (higher) threshold. The second section (downstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a second (lower) threshold. The disclosed subsea production system methodology, which uses barriers to divide the system components between two pressure ratings, may allow for enhanced development of HPHT reservoirs.

  • Patent number: 9541005
    Abstract: There is described a system and method for filling an engine fuel manifold. An adaptive filling function is used to determine a flow rate at which fuel is to be delivered to the fuel manifold. The filling function receives as an input a present measurement of the engine's speed and computes the flow rate accordingly. The fuel manifold may then be filled according to the computed flow rate so as to match the engine's speed. Appropriate fuel/air ration conditions can therefore be achieved for successful engine start.

  • Patent number: 9383035
    Abstract: In one embodiment, a constant-flow valve assembly is provided that comprises a first fluid passageway carrying fluid at a first fluid pressure, a piston chamber, and a second fluid passageway connected to the chamber and carrying fluid at a second fluid pressure. A third fluid passageway is configured to carry fluid at a third fluid pressure. An adjustable valve member is provided between the chamber and the third passageway to provide constant fluid flow to the third passageway. An adjustable restrictor assembly is positioned between the first and second fluid passageways. An inlet portion of the restrictor assembly receives fluid at the first fluid pressure and directs the fluid to a restrictor. An outlet portion receives fluid from the restrictor and directs the fluid to the second fluid passageway at the second fluid pressure.

  • Publication number: 20150122358
    Abstract: Disclosed valves for drinking from a portable fluid container allow for manual actuation of the valve between an open configuration that permits fluid flow and a closed configuration that substantially prevents fluid flow. Disclosed valves comprise a valve housing having inner bore fluidly coupled to an inflow channel and an outflow channel that are angled with respect to one another, and a reciprocating valve member that is adjustably positioned partially within the bore to open and close the fluid flow pathway through the bore from the inflow channel to the outflow channel. The reciprocating valve member is shaped such that it can prevent fluid flow when fully inserted within the bore to a closed configuration, and can allow fluid flow when the valve member is retracted from this closed position by a relatively short distance to an open configuration.
