The piston islubricated by four Mollerup lubricators,which force the oil between the piston andthe cylinder; there are four inlets to thecylinder, and they are arranged to enter onthe fore and aft and athwartship centrelines. There are seven vaJlves and! anindicator cock in the cylinder valves are operated in the usual wayby cams and cam levers.

The pressure ofthe scavenging air is 3 lb. per sq. are four valves in the cylinder headfor the inlet of the scavenging air to copewith the large volume of low pressure airused in the engine. The scavenging pumpsare controlled by two piston valves workedby slipping eccentrics driven from the aftpart of the two piece interchangeable builtup crank shaft, and the change of angularpositon permitted by the slipping of theeccentric on the crank shaft automaticallyreverses the scavenging pump piston scavenging air is led by cast ironpipes from the valves to a built up 3-16 riveted steel plate reservoir runningalong the cylinder top and supplying thefour scavenging valves on each exhaust is led down by bent cast ironpipes from the cylinder belt to the mainexhaust pipe running along the engine tothe cast iron silencer.
