Title
(EN) CROSSHEAD AND CROSSHEAD-TYPE INTERNAL COMBUSTION ENGINE
(FR) CROSSE ET MOTEUR À COMBUSTION INTERNE DE TYPE À CROSSE
(JA) クロスヘッドおよびクロスヘッド式内燃機関
Abstract
(EN)
A crosshead (4) that comprises a lubricant passage (50) that distributes lubricating oil to a piston rod (21) and a connecting rod (25). The lubricant passage (50) has: an introduction channel (51) that extends from an outer surface of a crosshead pin (41) to the inside; a first branch channel (52) that branches from the introduction channel (51) and communicates with an oil channel (21b) that is provided inside the piston rod (21); and a second branch channel (53) that branches from the introduction channel (51) and communicates with an oil channel (25b) that is provided inside the connecting rod (25). The first branch channel (52) and the second branch channel (53) communicate with each other as viewed in a cross-section that passes through the piston rod (21) and the connecting rod (25).
(FR)
L'invention porte sur une crosse (4) comprenant un passage de lubrifiant (50) qui distribue de l'huile lubrifiante à une tige de piston (21) et une bielle (25). Le passage de lubrifiant (50) comporte : un canal d'introduction (51) qui s'étend à partir d'une surface extérieure d'une tige de crosse (41) vers l'intérieur ; un premier canal de ramification (52) qui part du canal d'introduction (51) et communique avec un canal d'huile (21b) qui est disposé à l'intérieur de la tige de piston (21) ; et un second canal de ramification (53) qui part du canal d'introduction (51) et qui communique avec un canal d'huile (25b) qui est disposé à l'intérieur de la bielle (25). Le premier canal de ramification (52) et le second canal de ramification (53) communiquent l'un avec l'autre comme observé dans une section transversale qui traverse la tige de piston (21) et la bielle (25).
