Abstract
【解決手段】空気取入路16を具備した固定子10と、回転子12と、最高速度レベルを決定する調速装置とを有し、回転子12に接続された速度反応アクチュエータ34と、モーター速度レベルが予定の最高レベルを超えて到達することで、速度調節の不調になる際に、アクチュエータ34によって、通常の開口位置から閉鎖位置へシフト可能な弁33とを備えた、空気圧回転モーター用の過速度安全装置であり、アクチュエータ34が、回転子12に接続され、且つ遠心力の作用に感応する、スプリングでバイアスされる接触要素48を備え、弁33がディスク型の弁要素36を備えており、弁要素36は、取入路16に回動可能に支持されて、一方の磁石42によってその開口位置に保持され、他方の磁石43によってその閉鎖位置に保持される。

- 空気取入路(16)を具備した固定子(10)と、速度反応アクチュエータ(34)を具備した回転子(12)と、前記アクチュエータ(34)によって開口位置から閉鎖位置へシフト可能な弁(33)とを備え、速度反応アクチュエータが回転子(12)に、それと共に回転するために接続されており、
前記アクチュエータ(34)が、遠心力によって停止位置と作動位置との間を放射方向に可動な接触要素(48)と、前記接触要素(48)を予定最高速度レベルの下のモーター速度レベルで、前記停止位置に保持し、且つ前記接触要素(48)を前記最高速度レベルの上のモーター速度レベルで、前記作動位置へ、放射方向に動かすために配置されたスプリング(46)とを備え、それによって前記弁(33)を前記開口位置から前記閉鎖位置へシフトを行う、
空気圧回転モーター用の過速度安全装置において、
前記弁(33)が、前記開口位置と前記閉鎖位置との間を移動するように、回動軸(37)の周囲を回転可能なディスク型の弁要素(36)を備え、それは前記開口位置において前記弁要素(36)が、実質的に取入路(16)と並行に配置され、前記閉鎖位置において前記弁要素(36)が、取入路(16)に対して横方向に配置されること、
前記回動軸(37)が取入路(16)に対して横方向に延び、回転子(12)の回転軸に関して横にずれて設定された位置に配置され、前記接触要素(48)が前記停止位置を取る時、前記開口位置において前記弁要素(36)が、前記接触要素(48)によって届いておらず、前記作動位置において前記接触要素(48)が、放射方向に伸びて、前記弁要素(36)に当たり、それを前記開口位置から前記閉鎖位置へシフトさせ、前記保持手段(42)が前記要素(36)を解放可能に前記開口位置に保持すること、
を特徴とする過速度安全装置。 - 前記弁要素(36)が、鉄製の材料から作られており、前記保持手段が、取入路(16)に取り付けられ、且つ前記弁要素(36)を前記開口位置に、引き寄せて保持するために配置された、第一磁石(42)と、前記弁要素(36)を前記閉鎖位置に、引き寄せて保持するために配置された、第二磁石(43)とを備えることを特徴とする請求項1に記載の過速度安全装置。
- 取入路(16)が、前記閉鎖位置で取入路(16)に対し実質的に横方向に配置され、且つ前記弁要素(36)と接合するように配置された、軸線方向に面する弁座表面(41)によって形成されること、を特徴とする請求項1または2に記載の過速度安全装置。
- 前記スプリング(46)が、同心配置で回転子(12)に接続され、且つ前記接触要素(48)を支持する自由端部を有する、実質的に直線状のロッドによって形成されること、を特徴とする請求項1〜3のいずれか一項に記載の過速度安全装置。
