Fifteen mechanical problems : reasons for their existence and their solution (1915)
Sargent, Charles Elliotte · leaf 237
n D is at the top of the stroke the crankcase is full of air at atmospheric pressure, having entered through the port Kwhich registers with the port in disc (Figs.2 and 4). Upon the downward strokethis air is compressed in the crank case and flowing through the passage F andvalve S fills the… … I L5 in the receiver the discharge valve H opons. As the pressure in the crankcase assists the piston on the up stroke, and the port on disc is so locatedthat it does not open the port K until atmospheric pressure is reached, no workis lost, and a high efficiency is maintained. As there are two…
