  • Patent number: 9897256
    Abstract: A method of continuously conveying compressed gas to a plurality of vehicles, where the plurality of vehicles includes at least a first vehicle having a higher tank pressure and a second vehicle having a lower tank pressure that are simultaneously seeking compressed gas from the same delivery conduit. The method includes compressing gas using at least one compressor, conveying the compressed gas from the at least one compressor to a backpressure apparatus, conveying a non-bypass fill portion through the backpressure apparatus, diverting a bypass fill portion through a bypass conduit to at least one distributor, conveying the bypass fill portion through the at least one distributor to at least one of the one or more delivery conduits and subsequently to at least the first vehicle, and conveying the non-bypass fill portion through at least one of the one or more the delivery conduits to at least the second vehicle.

  • Patent number: 9772068
    Abstract: A compressed gas delivery system includes a control system and at least one compressor fluidly connected to the control system for providing a compressed gas to the control system. The system also has a backpressure apparatus that is fluidly connected between the at least one compressor and the control system. The backpressure apparatus conveys a portion of the compressed gas to the control system. The compressed gas delivery system also includes a bypass conduit that is fluidly connected between the at least one compressor and the backpressure apparatus. The bypass conduit conveys a portion of the compressed gas through the flow limiting distributor directly to one or more vehicles during a dispensing operation.
