20140158216 | FUEL TANK VENT VALVE ASSEMBLY AND METHOD OF ASSEMBLY - 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. | 06-12-2014 |
20150096633 | VALVE ASSEMBLY - 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. | 04-09-2015 |
20150144819 | ISOLATION VALVE WITH FAST DEPRESSURIZATION FOR HIGH-PRESSURE FUEL TANK - 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. | 05-28-2015 |
