PURPOSE:To make a tank compact, by fixing a compressor mounting stand on a lid plate located at the upper portion of the tank, and projecting a drive shaft of a compressor detachably mounted on the compressor mounting stand into the stand. CONSTITUTION:An engine body 4 is mounted on the lower side of a lid plate 3 covering an upper portion of a tank 1 under a submerged condition. A mounting stand 18 is fixed on the lid plate 3, and a compressor 17 is detachably mounted on the stand 18. A rotating shaft 19 of the compressor 17 is projected into the mounting stand 18, and a coupling 20 is fixed at a projecting end of the shaft 19. Accordingly, the lid plate may be lowered to the tank by a distance equal to a height of the mounting stand, thereby making the tank itself compact.
