Claims (2)
- 加圧空気供給通路(14)を備えたハウジング(10)と、空気圧モーター(15)と、出力軸(18)と、モーター(15)を出力軸(18)に間欠的に連結しまたモーター(15)に接続された慣性駆動部材(21)を包含する衝撃ユニット(20)と、バルブロッド(26)を備えまた目標トルクレベルの達成でモーター(15)への加圧空気供給を遮断するよう配置された遮断弁(23)と、慣性駆動部材(21)に支持され移動可能な減速応動慣性要素(28)を備えた、遮断弁(23)を作動する機構(25)と、慣性要素(28)によって変位可能で且つ遮断弁(23)の完全に開放された位置でバルブロッド(26)を端面支持するための主接触面(34)を設けた引はずし要素(24)とを有し、引はずし要素(24)が、引はずし要素(24)の変位で主接触面(34)とのアラインメントから外れたバルブロッド(26)を受けるための開口部(32)を備え、それにより完全に開放された位置から完全に閉鎖された位置に向けて遮断弁(23)の動きを可能にする空気圧トルク衝撃レンチにおいて、
引はずし要素(24)が、開口部(32)の縁部に位置する1つ以上の肩部(35、36)を備え、部分的に遮断弁(23)を閉鎖する1つ以上の位置でバルブロッド(26)を端面支持するための第二の接触面を1つ以上形成することによって、目標トルクレベルに接近する際に連続的に増大する慣性駆動部材(21)の減速規模で遮閉弁(23)の段階的な閉鎖を達成することを特徴とする衝撃レンチ。 - 前記肩部のうちの1つ(35a)が、遮断弁(23)の閉鎖方向でバルブロッド(26)の連続的に前進する支持位置を提供する傾斜した接触面を有し、それぞれの位置が連続的に増加する慣性駆動部材(21)の減速規模による引はずし要素(24)の実際の段階的な変位に依存することを特徴とする請求項1に記載の衝撃レンチ。
