Description
〔発明の利点〕
機器のケースと電子回路の適当な接続線、例えば電子回路のアース接続線との間の電圧に依存している抵抗(バリスタ)、或いはこれと類似の電気的構成要素の回路によって、この 有利な方法によれば更に、この構成要素によって、例えば空気の流れによって発生する機器のケースの静電電荷が逃される。
上述の様な構造の故に、電子回路8又は9を静電パルス及び電磁放射から保護することが必要である。この目的のために、電圧依存性の抵抗器、例えばバリスタの様な電気的構成要素、或いはダイオード、火花ギャップ、コンデンサの様な構成要素が、スロットル弁スリーブと適当な接続部、例えば少なくとも一つの電子回路のアース接続の接続部との間に取り付けられている。静電放電パルスだけに対する保護は、反対方向に直列に接続された二つのツェナーダイオードによって達成される。
Claims (5)
