A fea-ture of these engines is that the low-pressure piston is easily accessible for inspection or repairs from between the two cylin-ders. Effective lubrication is provided for journals, guides,etc., by means of a gravity system, with elevated oil tanks in theengine room for gravity flow. The condensers, which are located beneath in the basement,are mechanically operated from the main engines by means of.

The airpumps are arranged vertically in a single body for each engine,and are of the duplex single-acting type. Suction valves areomitted, whereby the resistance to the entering water is reducedand the pumps tend toward noiseless operation.
