Abstract

　油圧装置において、第１回転部材（２５）及び第２回転部材（３６）を同一の中心軸心（Ｏ）をもって相対回転自在に設け、第１回転部材（２５）にカム（２６）を設け、第２回転部材（３６）にカム（２５）に対向してピストン（３８ａ～３８ｈ）を配置し、圧縮コイルスプリング（４０ａ～４０ｈ）によりピストン（３８ａ～３８ｈ）をカム（２６）に接触するように押し付け、第２回転部材（３６）にピストン（３８ａ～３８ｈ）の移動に伴って容積が拡大縮小する油室（４１ａ～４１ｈ）を設け、この油室（４１ａ～４１ｈ）に対してオイルが流入または排出する第１流体通路及び第２流体通路を設け、この第１流体通路及び第２流体通路の圧力差に応じて第１流体通路及び第２流体通路におけるオイルの流入方向及び排出方向が切換わる通路切換装置（８）を設ける。
