【考案の詳細な説明】
本考案は内燃機関用ターボチャージャーの潤滑油戻し管
装置に関し、更に限定して云えば既設の内燃機関にター
ボチャージャーを附加してその性能向上を計る場合の、
ターボチャージャー軸承室より機関クランク室への潤滑
油の戻し管装置の改良に関するものである。[Detailed description of the invention] The present invention relates to a lubricating oil return pipe device for a turbocharger for an internal combustion engine, and more specifically, when a turbocharger is added to an existing internal combustion engine to improve its performance.
This invention relates to improvement of a return pipe device for lubricating oil from a turbocharger bearing chamber to an engine crank chamber.

向上を行わせる場合に、従来はそのタービン軸潤滑油の
軸承室から機関クランク室への戻し管を、クランク室側
面にニップルを新設して、これに上記戻し管を接続して
居るのである。When adding a turbocharger to an engine in use to improve its performance, conventionally a return pipe for the turbine shaft lubricating oil from the bearing chamber to the engine crank chamber was installed with a new nipple on the side of the crank chamber. The return pipe mentioned above is connected to this.
然しこの場合クランク室内は機関運転中には常時脈動圧
となっているので、該脈動圧による上記戻し管内の気柱
振動が成る条件になった時、管内の油の流下を妨げ軸承
室内の潤滑油を不良にし、軸の焼付きを生ずる不具合が
たまたま発生する。However, in this case, the pressure in the crank chamber is always pulsating during engine operation, so when the pulsating pressure causes the air column vibration in the return pipe to occur, it prevents the oil in the pipe from flowing down and reduces the lubrication in the bearing chamber. It just so happens that a problem occurs that causes the oil to become defective and cause the shaft to seize.

説明する。In this invention, the oil return pipe is installed inside the oil pan at the bottom of the crankcase and by using the plug seat of the oil pan's drain plug, and a new nipple is purposefully installed on the crankcase wall as described above. The device of the present invention will be explained next with reference to the drawings.

である。In the oil return pipe installation according to the present invention, a plug pipe 15 that protrudes into the drain plug seat 14 provided at the bottom of the lower oil pan 11 of the crankcase with a size that fits inside the oil pan 11 is installed.
is attached, and the oil return pipe 9 is extended and connected to this 9'.
第３図に上記プラグ管１５部分を拡大して示す。FIG. 3 shows an enlarged view of the plug pipe 15 portion.
