Claims (5)
- ツールをその長軸方向に移動可能に内部に配設することができるフレームと、打撃装置に圧力液体を供給し、圧力液体タンクに圧力液体を戻す手段と、該圧力液体の圧力を利用することにより前記ツール内に応力パルスを発生させる手段とを含み、圧力液体で満たされた作動圧力チャンバと、該作動圧力チャンバおよび前記ツールの間にあって、前記フレームの長軸方向に移動可能に配設されて少なくとも応力パルス発生中は前記ツールに直接的または間接的に接触する伝達ピストンと、該伝達ピストンの該ツールに面する側にある供給圧力チャンバとを含み、該伝達ピストンは、前記作動圧力チャンバに面する圧力面と、前記供給圧力チャンバの側にあって前記ツールに面する圧力面とを備える圧力流体作動打撃装置において、前記応力パルスを発生させる手段は、前記作動圧力チャンバに接続されて該作動圧力チャンバ内の圧力を維持する圧力液体源である第1の圧力液体供給手段と、断続的に圧力液体を前記供給圧力チャンバに供給する第2の圧力液体供給手段とを含み、第2の圧力液体供給手段は圧力液体を該供給圧力チャンバに供給して、該圧力液体の圧力によって前記伝達ピストンは前記作動圧力チャンバの方へ、該作動圧力チャンバ内の前記圧力液体の圧力に抗って、かつ前記伝達ピストンの所定の後退位置へ押し、これにより前記作動圧力チャンバ内の液体は該作動圧力チャンバから排出され、第2の圧力液体供給手段は、該圧力液体の供給圧力チャンバへの供給と交互に、圧力液体を前記供給圧力チャンバから急速に排出させて、これにより前記作動圧力チャンバ内の、および第1の圧力液体供給手段から該作動圧力チャンバに流れ込む加圧された圧力液体の力が、前記後退位置にあって実質的に前記ツールと接触している前記伝達ピストンを前記ツールの方向に押して、該ツールをその長手方向に押して、前記ピストンが前記ツールを押している間該ピストンを該ツールに接触させたまま、該ツール内に応力パルスを発生させ、第1の圧力液体供給手段は、圧力液体を供給して、前記作動圧力チャンバ内の圧力を、該打撃装置の作動中、実質的に一定に維持するよう構成されていることを特徴とする圧力流体作動打撃装置。
- 請求項1に記載の打撃装置において、等しい圧力の圧力液体が前記作動圧力チャンバおよび前記供給圧力チャンバに供給され、該作動圧力チャンバおよび該供給圧力チャンバに面する前記伝達ピストンの前記圧力面はそれぞれ、発生している力の和によって該伝達ピストンがその後退位置へ押されるよう大きさが決められていることを特徴とする圧力流体作動打撃装置。
- 請求項1または2に記載の打撃装置において、前記作動圧力チャンバは第1の圧力液体供給手段に接続されて、第1の圧力液体供給手段が継続的に圧力液体を前記作動圧力チャンバに供給しようとすることを特徴とする圧力流体作動打撃装置。
- 請求項1ないし3のいずれかに記載の打撃装置において、該打撃装置は前記作動圧力チャンバに接続された蓄圧装置である第3の圧力液体供給手段を含むことを特徴とする圧力流体作動打撃装置。
- 請求項1に記載の打撃装置において、第1の圧力液体供給手段は圧力液体ポンプであることを特徴とする圧力流体作動打撃装置。
