Claims (1)
- ハウジング内のシリンダ内にピストンを摺動自在に嵌挿してシリンダ内にピストン上室とピストン下室を画成し、前記ピストンが初期位置に復帰した際の衝撃を吸収するヘッドバンパを前記ハウジング内に固定するとともに、前記シリンダの外周に沿って移動して前記ピストン上室をハウジング内の蓄圧室又は大気に選択的に連通させるスリーブバルブを設け、初期状態において前記スリーブバルブを前記ヘッドバンドに嵌合させて前記ピストン上室と前記蓄圧室との連通を遮断するとともに、ピストン上室を大気に連通させ、打込作業が開始されると前記スリーブバルブを移動させて前記ピストン上室を前記蓄圧室に連通させるとともに、ピストン上室と大気との連通を遮断し、蓄圧室からピストン上室に流入する圧縮空気の圧力によって前記ピストンをシリンダ内で急激に移動させて止具を打撃するようにした打込機において、
前記ヘッドバンパに、前記ヘッドバンパと前記ハウジングとの接触面を前記シリンダ上室に連通させる排気孔を形成し、
前記蓄圧室から前記ハウジングと前記ヘッドバンパとの接触部へ侵入する圧縮空気を、前記排気孔を介して大気中に排出することを特徴とする打込機。
