本考案は、ニューマチックガバナを有するディーゼル機
関において、ニューマチックガバナ負圧室に溜った潤滑
油を機関本体へ戻すようにした吸引装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a suction device for returning lubricating oil accumulated in a pneumatic governor negative pressure chamber to the engine body in a diesel engine having a pneumatic governor.
従来のニューマチックガバナを有するテ′イーゼル機関
においては、ニューマチックガバナ負圧室内に常にベン
チュリーで発生する負圧が作用している。In a conventional easel engine having a pneumatic governor, negative pressure generated by a venturi always acts within the negative pressure chamber of the pneumatic governor.
そのため、燃料噴射ポンプを潤滑している潤滑油がコン
トロールラックを伝わって大気圧室に入り、これがダイ
ヤフラムを介して経済的に負圧側に吸引され、負圧室に
潤滑油が溜ってくる。Therefore, the lubricating oil that lubricates the fuel injection pump passes through the control rack and enters the atmospheric pressure chamber, which is economically sucked into the negative pressure side through the diaphragm, and the lubricating oil accumulates in the negative pressure chamber.
この負圧室に溜った潤滑油の量がある程度増加してくる

圧室に正確に伝達されなくなり、或いは溜った油がダイ
ヤフラムの変位を妨げることになり、機関が突然停止し
たり吹き上がったりして、機関運転に異常を来たす。When the amount of lubricating oil accumulated in this negative pressure chamber increases to a certain extent, it will accumulate in the path between the venturi and the governor negative pressure chamber, and the negative pressure characteristics of the venturi will remain as they are in the governor negative pressure chamber. If the oil is not transmitted or the accumulated oil prevents the displacement of the diaphragm, the engine may suddenly stop or blow up, causing abnormal engine operation.

を外部に廃棄し不経済であった。Conventionally, the negative pressure chamber of a general pneumatic governor is completely sealed except for the negative pressure inlet leading to the venturi, and the lubricating oil accumulated in the negative pressure chamber does not move at all, or the negative pressure chamber is located below the negative pressure chamber. A drain cock is provided in the chamber to periodically take out the lubricating oil from the negative pressure chamber to the outside, but it is complicated to take out the lubricating oil regularly and it is uneconomical to dispose of the lubricating oil outside. Ta.
