動軸4を支承する軸受け3の上方にピストン8により区
割されたオイルリザーバ室9を、またピストン8の上方
にタービン2を駆動した汚水の一部が浸入する室11を
設けたものにおいて、上記室11を本体1に設けた透孔
1aを介してアニユラス7に連通させると共に、上記室
11の上方にタービン2側から流入する汚水を制限する
シール部材13を設けてなるターボドリル。Above the bearing 3 that supports the drive shaft 4 that transmits the rotation of the turbine 2 to the pit 5 at the tip of the main body 1 is an oil reservoir chamber 9 divided by a piston 8, and above the piston 8 is the waste water that drove the turbine 2. In this device, the chamber 11 is communicated with the annulus 7 through the through hole 1a provided in the main body 1, and the sewage flowing into the upper part of the chamber 11 from the turbine 2 side is prevented. A turbo drill provided with a restricting seal member 13.
