Title
(EN) OIL DUCT
(FR) CONDUITE D'HUILE
(JA) 油導入管
Abstract
(EN)
Disclosed is an oil duct which is provided with a vertically-extending outer pipe, a vertically-extending inner pipe, and a seal for providing sealing between the outer pipe and the inner pipe. The inner pipe moves vertically with respect to the outer pipe together with the crosshead in a crosshead diesel engine. Oil flows into a space inside the outer pipe above the seal inside the outer pipe. The inner pipe includes an upper-side section which is positioned inside the outer pipe above the seal when the crosshead is in the bottom dead centre position, and a lower-side section which is positioned below the seal when the crosshead is in the top dead centre position. The lower-side section is connected to an oil flow passage provided in the crosshead. The top end of the upper-side section is closed. An opening is formed in the side wall of the upper-side section.

L'invention concerne une conduite d'huile qui comporte un tuyau extérieur s'étendant à la verticale, un tuyau intérieur s'étendant à la verticale, et un joint d'étanchéité procurant une étanchéité entre le tuyau extérieur et le tuyau intérieur. Le tuyau intérieur se déplace à la verticale par rapport au tuyau extérieur en même temps que la crosse dans un moteur diesel à crosse. L'huile s'écoule dans un espace à l'intérieur du tuyau extérieur au-dessus du joint d'étanchéité à l'intérieur du tuyau extérieur. Le tuyau intérieur comprend une section côté supérieur qui est positionnée à l'intérieur du tuyau extérieur au-dessus du joint d'étanchéité quand la crosse est dans la position point mort bas, et une section côté inférieur qui est positionnée sous le joint d'étanchéité quand la crosse est dans la position point mort haut. La section côté inférieur est raccordée à un passage d'écoulement d'huile mis en œuvre dans la crosse. L'extrémité supérieure de la section côté supérieur est fermée. Une ouverture est formée dans la paroi latérale de la section côté supérieur.

 油導入管は、上下に延びる外管と、上下に延びる内管と、外管と内管との間をシールするシールとを具備する。内管は、クロスヘッド型ディーゼルエンジンのクロスヘッドとともに外管に対して上下に移動する。外管内のシールより上の外管内空間に油が流入する。内管は、クロスヘッドが下死点位置にあるときにシールより上で外管内に位置する上側部分と、クロスヘッドが上死点位置にあるときにシールより下に位置する下側部分とを含む。下側部分は、クロスヘッドに設けられた油流路に接続される。上側部分の上端が閉じられている。上側部分の側壁に開口が形成される。
