  • Publication number: 20170191580
    Abstract: An isolation valve includes a flow restrictor in a passage and having an orifice and configured to provide a first, second, and third flow paths. A spring may bias the flow restrictor to an open position that opens the second flow path. A solenoid assembly may include a coil and an armature moveable between an extended position that moves the flow restrictor to close the first, second, and third flow paths, and a retracted position that opens the first flow path. The first flow path may include a path from a first reservoir through the orifice to a second reservoir. The second flow path may include a first flow direction from the first reservoir to the second reservoir via a second path, the second path including a space between the flow restrictor and the passage. The third flow path may include a second flow direction from the second reservoir to the first reservoir via the second path.

  • Patent number: 9624875
    Abstract: A valve assembly for a high-pressure fluid reservoir includes an isolation valve having a selectively energizable coil, an armature that is moveable between a first position when the coil is energized and a second position when the coil is de-energized, and an isolation valve seal coupled to the armature. The assembly also includes a float valve having a float with a passage at a bottom portion and an orifice at a top portion of the float, wherein the isolation valve seal is aligned to open and close the passage and wherein vapor flows through the passage and the orifice when the coil is energized during a high pressure condition. A housing houses both the isolation valve and the float valve and has a port that is opened and closed by the float valve.

  • Patent number: 9500291
    Abstract: An isolation valve may include a flow restrictor disposed in a passage having non-parallel sides, the flow restrictor having an orifice. A flow restrictor spring may apply a biasing force on the flow restrictor to bias the flow restrictor to an open position. A solenoid assembly may include having a coil and an armature that may be moveable between (i) an extended position that overcomes the biasing force of the restrictor spring to move the flow restrictor to a closed position and to close the second orifice, and (ii) a retracted position to open the orifice. If the coil is energized, the armature may move to the retracted position to allow vapor to flow through the orifice at least until the biasing force of the flow restrictor spring overcomes a vapor pressure. The open position of the flow restrictor may allow vapor to flow through a space between the flow restrictor and the passage.

  • Patent number: 9371803
    Abstract: An angle flow valve comprises a housing and a cover. The housing comprises a first recess for receiving a flow restrictor, a second recess for receiving a relief valve, a first port fluidly connected to the first recess, an angled flow path fluidly connected to the first recess and to the second recess, a second port fluidly connected to the angled flow path, and a relief passage between the first recess and the second recess. The first recess is parallel to the second recess, permitting drop-in assembly of the flow restrictor and relief valve. The cover comprises a solenoid assembly, and the cover couples to the housing by adjoining the solenoid against the flow restrictor and by adjoining the cover against the relief valve. A single o-ring seals the leak path between the cover and the housing.

  • Patent number: 9360872
    Abstract: A vent valve assembly includes a first housing component, a second housing component, and a third housing component, as well as a first valve and a second valve. The first, second, and third housing components are configured to assemble together along one directional axis with the second housing component, the first valve and the second valve between the first and third housing components and with the second valve laterally-spaced from the first valve. A vapor flow path directs vapor from the first valve to the second valve, thereby reducing an overall height of the vent valve assembly.

  • Publication number: 20160123490
    Abstract: An angle flow valve comprises a carriage. The carriage comprises a first recess, a flow restrictor in the first recess, a second recess, and a relief valve in the second recess. A first port is fluidly connected to the first recess. An angled flow path is fluidly connected to the first recess and to the second recess. A second port is fluidly connected to the angled flow path. The first recess is parallel to the second recess. A solenoid assembly is mounted to the carriage. The solenoid assembly comprises a lead, a bobbin, coil windings, a pole piece, a flux collector, and a sleeve. An integrally formed overmold layer surrounds the carriage and the solenoid assembly.
