Definitions

  • the present invention relates in general to the art of charging and withdrawing gas from containers. More specifically, the present invention relates to a charging system and process which effects sequential charging of a group of containers beginning with the container having the highest residual pressure before charging and ending with the container having the lowest residual pressure, and which effects sequential withdrawal beginning with the container having the lowest pressure before withdrawal commences and ending with the container having the highest pressure.

  • the sequencer valve-means each hasaifillposition and a transfer position.
  • Means is provided for maintaining each sequencer valve means in its fill position and in communication with its container below a predetermined pressure, typically the rated pressure of the containers.
  • Means is also provided for each sequencer valve means to change the valves position from its fill position to its transfer position in response to the predetermined pressure existing in its associated container and to then establish communication between a downstream valve and the gas source.
  • Means is also provided to prevent gas communication between a container and the source of pressurized gas when another container is being charged.
  • each sequencer valve means control of flow of gas from the source of pressurized gas to succeeding containers in a series of containers by preventing gas communication beyond the valve means admitting to gas flow to its container. This may be done by connecting the source of gas to the containers in series through the sequencer valve means and providing each sequencer valve means with means for preventing gas flow downstream from it when it is admitting to gas flow into its container.

  • the predetermined pressure would be lower than the rated pressure of the container.
  • the present invention also contemplates the selective charging of other vessels or containers from the storage containers by charging from the storage container having the lowest beginning pressure initially and ending at the storage container having the highest beginning initial pressure.

  • each valve On the withdrawal side of each valve a draw and bypass spool is provided, the position of which between a draw position and a bypass position is determined by its container pressure and a reference pressure.

  • container 14 when there is not enough time to bring all the containers up to rated pressure between withdrawals, container 14 will always have a residual pressure before charging in excess of the residual pressure in containers l6 and 18. Similarly, container 16 will have a residual pressure before charging in excess of the pressure existing in container 18. Of course, if there is sufficient charging time between withdrawals, all the containers will be at the same pressure. But for purposes of this discussion it will be assumed that there is insufficient time to bring all the containers up to their rated pressure before withdrawal to a vehicle 's gas storage tanks.

  • each valve shifts from its bypass position to its draw position when its container pressure exceeds a given value relative to the pressure in the tanks being charged
  • the withdrawal side of each of the valves 20, 22 and 24 is in pressure communication with the tanks being charged through parallel branch lines 56, 58 and 60, respectively, all of which are connected to the tanks being charged downstream of transfer valve 36 through a common line 62.

  • Line 26 from valve 20 opens into bore 66 for incoming gas and, as such, constitutes an inlet line for the valve.
  • Line 28 also opens into the bore for outgoing gas to valve 24 and, as such, constitutes an outlet line from the valve.

  • the reference pressure chamber is in direct communication with reference pressure vessel 40.
  • the latter vessel is in thermal communication with container 16.
  • the pressure in the reference pressure chamber is determined by the temperature of gas within container 16. Because the gas in the reference pressure chamber line 46 and vessel 40 constitutes a closed system, the reference pressure in the chamber is a direct function of temperature. As a consequence, when the temperature in container 16 is relatively high, so will be the pressure in reference pressure chamber 76. The converse is also true.
  • the pressure in vessel 40, acting in chamber 76, is such that during charging spool 70 will shift to its transfer position when the pressure exerted on it from 7 68 and emanates from the transfer chamber of valve 20.

  • Line 27 leads to the part of valve 20 corresponding to line 26 in FIG. 2.
  • O-rings are provided to prevent leakage of gas from or to the channel along the interface between the spool and the wall of bore 68. These O-rings are indicated by reference numerals 102, 104 and 106 and are disposed in lands 108, 110 and 112, respectively.
  • Spool 72 shifts to its bypass position when the pressure in the tanks being charged and biasing spring 98 is sufficient to overcome the pressure within container 16 acting in chamber 74.
  • line 34 leads from the valve at the same location that line 32 leaves valve 22 but goes directly to the tanks being charged.
  • Line 37 leads either to a compressor shutdown device of the compressor inlet to control the compressor when all tanks are filled.
  • the compressor will be in direct communication with line 26 through line 30, channel 100 and line 101. With this communication, the compressor directly charges the vehicles tanks.

  • compressor 10 will still be in communication with the vehicles tanks through channel 100 and line 26 (the latter corresponding to line 32 in FIG. 2).
  • valve 20 the compressor is connected through line 12 to the part corresponding to line 30 in FIG. 2 so that when all available gas has been transferred from container 14 to the vehicle being charged, the movement of the spool of valve 20 corresponding to spool 72 will connect the compressor directly to the vehicle. During this final filling mode no gas will be placed in the storage tanks.
  • container 18 So long as container 18 has more pressure than the vehicle to be charged, withdrawal will begin with container 18.

  • the biasing spring of valve 24 and tank pressure will force the draw and bypass spool to its bypass position and gas transfer to the tanks of the vehicle will switch to container 16. The same sequence of events occurs in changing from container 16 to container 14.
  • valve 20 admits to direct communication between the tanks of the vehicle being charged and the compressor.
  • the present invention provides a chargingsystem and process which, by charging storage containers having the highest beginning residual pressure first, maximizes the filling of vehicle tanks because the charging sequence maximizes available container pressure.
