Enhanced Storage System
A compressed natural gas (CNG) refueling station system includes a station storage container configured to receive gas at a first pressure, a dispenser configured to deliver CNG to a vehicle tank up to a second pressure below the first pressure, and a pressure regulator disposed between the station storage container and the dispenser.
1 . A compressed natural gas (CNG) refueling station system, comprising:
a station storage container configured to receive gas at a first pressure;
a dispenser configured to deliver CNG to a vehicle tank up to a second pressure below the first pressure; and
a pressure regulator disposed between the station storage container and the dispenser.
2 . The CNG refueling station system of claim 1 , wherein the pressure regulator is configured to restrict an output pressure to a pressure lower than a maximum allowable pressure of a vehicle tank connected to the dispenser.
3 . The CNG refueling station system of claim 1 , wherein the station storage container is in fluid communication with each of a compressor and the dispenser via a single connection.
4 . The CNG refueling station system of claim 3 , wherein the pressure regulator is disposed between the station storage container and each of the compressor and the dispenser.
5 . The CNG refueling station system of claim 4 , further comprising:
a check valve connected both upstream and downstream relative to the pressure regulator.
6 . The CNG refueling station system of claim 5 , further comprising:
a first actuated valve connected both upstream and downstream relative to the pressure regulator.
7 . The CNG refueling station system of claim 6 , further comprising:
a first pressure switch connected between the station storage container and the pressure regulator.
8 . The CNG refueling station system of claim 7 , wherein the first actuated valve is actuated as a function of the operation of the first pressure switch.
9 . The CNG refueling station system of claim 8 , further comprising:
a second actuated valve disposed between the pressure regulator and each of the compressor and the dispenser.
10 . The CNG refueling station system of claim 9 , further comprising:
a second pressure switch connected between the second actuated valve and the dispenser.
11 . The CNG refueling station system of claim 10 , wherein the second actuated valve is actuated as a function of the operation of the second pressure switch.
12 . A compressed natural gas (CNG) refueling station system, comprising:
a compressor;
a plurality of station storage containers connected downstream relative to the compressor;
a dispenser comprising a plurality of dispenser valves, each dispenser valve selectively in unrestricted fluid communication with respective station storage containers; and
each dispenser valve selectively in restricted fluid communication with respective station storage containers via a single pressure regulator.
13 . A compressed natural gas (CNG) refueling station system, comprising:
a compressor;
a station storage container connected downstream relative to the compressor;
a plurality of dispensers connected downstream relative to the station storage container; and
a plurality of pressure regulators, each dispenser being connected to the station storage container via separate ones of the plurality of pressure regulators.
