For this arrangement there are also for working a steam-driven com- pressor. The electric-driven lubricating pumps suck up the oil from the tank, which is placed in the bottom of the ship, through the main-bearings, thence through the crank shaft, connecting rod brasses, through the hollow-bored con- necting rod to the cross-head brasses, . from there through the piston rod to the top of the oil-cooled piston, back through the piston rod, finally injecting over the gtide. Cooling the oil takes place on the guide-faces as these are cooled, and further cooling can be ex- ecuted by pumping oil through an oil- cooler formed as a surface condenser. From the two compressors of the auxiliary motors, which are carried out as triple-compressors, pipes are led from the intermediate cooler with an = air pressure of about 8 atm. to the siren, which is fitted on the mast. In the top of the casing two settling- tanks are arranged, to which fuel oil can be pumped from an air-driven pump in the engine room; each tank is of such dimensions that it contains suf- ficient oil for 12 hours normal work.
