The carries guide bars, the main air compressors, wards proaching the bottom of its stroke. The scavenging pistons also serve the purpose of Starting or reversing the engine, as by an arrangement of piston valves, operated from the start- the air upwards, thus ensuring the thor- ough cleansing of the cylinders. With the arrangement adopted in this type of engine, it may be pointed the bilge and circulating water pumps, etc. The cylinder liner and barrel are one casting, the space between form- ing a water jacket. The cylinder cov- ers and piston are also water-cooled, of 75 Ibs. per sq ing platform, air from the starting air receivers is admitted to the un- der side of these pistons at a pressure . in, which causes the motors to revolve in the desired dj- out the cylinder covers and tops are much simplified, the pistons are much more quickly accessible, and cams, levers and springs are reduced to a minimum.
