Abstract

Description
一方の圧縮容器(標準高圧金属シリンダー、50L容量)が、それから他方の容器に作動流体をポンプ送りすることにより吸引モードで2.0KPa(約200mmH2O)の圧力のガス源からのガスで完全に満たされる。一方の容器から他方の容器への作動流体の交互ポンピング(交互汲み出し)は、自動車の燃料タンク内へのガスの完全移動をもたらす。10L/min(毎分10リットル)の配送率の液圧駆動を利用したとき、50L容量の燃料タンク(ガソリンの10〜11Lに相当する)は、17時間をかけて20MPa(200バール)の圧力まで充填される。
本発明に従うガス充填装置の作動効率を向上させるため、充填中の圧縮容器の入口において住宅用のネットワーク(ガス供給網)から供給されるガスの圧力を2バールまで高めるプレ圧縮機が使用される。この場合、同量の圧縮ガスを得るのに要する時間が半減される。
本発明に従うガス充填装置の利便性を高めるために、蓄積容器、例えば、(車両が非介在の場合に)圧縮ガスで200バールまで事前に充填されてもよい50L容器が用いられても良い。この場合、蓄積容器に接続された車両の充填は、この容器からのガスの液圧移送により5分以内に行われる。
作動流体(30)が可動閉塞要素(44)の底部エッジに達すると、当該閉塞要素は低い位置から上動し、そのテーパー部によって接続具(47)のバルブ座部(46)を閉塞する。同時に、磁性インサート(45)が圧縮容器(1)の流体レベルセンサ(4)の領域を離れ、当該センサは、液体の流れを逆転モードに変えるために電子制御ユニット(25)に信号を送る。その逆転モードでは、電磁弁(9)及び(12)が閉じられ、電磁弁(10)及び(11)が開かれ、完全充填された圧縮容器(1)からの作動流体(30)が、圧縮容器(2)に進入し始める。圧縮容器(2)の外へガスを強制移送すると共に、ガスで圧縮容器(1)を満たすというプロセスは、上述のプロセスと同様のものである。ガス(29)の充填移送および作動流体(30)のポンプ送りのサイクルを繰り返すこと(反復すること)は、(車両の燃料タンク(22)に燃料供給するところの)出口側パイプライン(21)においてガス圧を次第に高める結果となる。出口側パイプライン(21)の圧力は、電気接触圧力計(24)によって監視されている。出口側パイプライン(21)が目標圧力に達すると、圧力計(24)は電子制御ユニット(25)に信号を送り、圧縮容器(1)又は(2)の流体レベルセンサ(4)の作動流体(30)に対する応答時に、電子制御ユニット(25)は、次の充填サイクルを開始すべく準備された初期状態で当該ガス充填装置の動作を停止する命令を発する。
作動流体(30)が可動閉塞要素(44)の底部エッジに達すると、当該閉塞要素は低い位置から上動し、そのテーパー部によって接続具(47)のバルブ座部(46)を閉塞する。同時に、磁性インサート(45)が圧縮容器(1)の流体レベルセンサ(4)の領域を離れ、当該センサは、液体の流れを逆転モードに変えるために電子制御ユニット(25)に信号を送る。その逆転モードでは、電磁弁(9)及び(12)が閉じられ、電磁弁(10)及び(11)が開かれ、完全充填された圧縮容器(1)からの作動流体(30)が、圧縮容器(2)の充填を開始する。圧縮容器(2)からガスを移すと共に(ガスで)圧縮容器(1)を満たすというプロセスは、上述のプロセスと同様のものである。ガス(29)の充填移送および作動流体のポンプ送りのサイクルを繰り返すこと(反復すること)は、(蓄積容器(31)を充填するところの)出口側パイプライン(21)においてガス圧を次第に高める結果となる。出口側パイプライン(21)の圧力は、電気接触圧力計(24)によって監視されている。出口側パイプライン(21)で目標圧力が達成されると、圧力計(24)は電子制御ユニット(25)に信号を送り、圧縮容器(2)の流体レベルセンサ(4)の作動流体に対する応答時に、電子制御ユニット(25)は、車両の燃料タンク(22)の充填を開始すべく準備された初期状態で当該ガス充填装置の動作を停止する命令を発する。
車両燃料タンク(22)が200バールの作動圧まで完全に充填されると共に、移送されなかった若干のガスが蓄積容器(31)に残った場合、電気接触圧力計(24)は電子制御ユニット(25)に信号を送り、該ユニットからは、コネクタ(23)の電磁弁を閉じる信号が送られる。作動流体(30)での蓄積容器(31)の充填は継続するが、ドレイン管(32)およびガス圧によって開かれたバイパス弁(33)を経由するガスは、車両燃料タンク(22)には入らず、作動流体での蓄積容器(31)の完全充填、流体レベルセンサ(4)の応答、および、蓄積容器(31)から圧縮容器(2)へのガスの完全強制移送の瞬間まで、圧縮容器(2)の方に入る。蓄積容器(31)の完全充填を知らせる流体レベルセンサ(4)の応答によって、液圧システムは、電子制御ユニット(25)からの信号によって、蓄積容器(31)から圧縮容器(2)に作動流体を戻す状態にもたらされ、その圧縮容器からのガスは、出口側パイプライン(21)を介して蓄積容器(31)に強制移送される。こうしてシステムは、圧縮容器(31)の充填を開始する準備が整った初期状態にもたらされる。
