Abstract

PURPOSE:To obtain an oil immersion preventing structure with high reliability by providing a pressure control mechanism for holding a pressure in the upper space of a crosshead higher than that in the lower space. CONSTITUTION:The open end 2a of a draft tube 2 to the space 6 inside a crank case is located a position where it is blocked by the crosshead 24 even when the crosshead 24 is located at lower dead point (c) in reciprocation. The open end 2b to the upper space of the crosshead is blocked by the side surface of the crosshead 24 when the crosshead 24 is located in the vicinity of the upper dead point (b), and when the crosshead 24 is located at the lower dead point (c), the open end 2b is located at the position connecting to the groove 1 provided on the crosshead 24. In such a positional relation the open ends 2a and 2b of the draft tube 2 are arranged so that it is possible to usually hold the average pressure in the upper space of the crosshead higher than that of the average pressure in the space 6 inside the crank case.
