<p>PURPOSE:To prevent leakage of oil in a crank chamber to the outside, by forming a sealing water chamber between a crosshead and one end portion of a cylinder, and communicating a water inlet part with a space formed between the cylinder and a piston and also with the outside via a water pipe. CONSTITUTION:Lubricating oil leaked from a crank chamber 2 along the sliding surface of a crosshead 3 is mixed with sea in a sealing water chamber 8, and the oily water is carried via an oily water recovering pipe 11a into a waste oil recovering means 11, in which oily water is recovered. Further, since a sealing section 12 is formed between the sealing water chamber 8 and a water inlet portion 13 and the water inlet part 13 is disposed between the sealing section 12 and a cylinder 5, it is prevented that the lubricating oil leaked from the crank chamber 2 into the sealing water chamber 8 is drawn directly into the cylinder 5.</p> |
