CYLINDER SEALING STRIPS
The sealing strip (fig. 4-21) prevents the loss of
steam from the cylinders by sealing the space between
the cylinder lip and the cylinder cover. As the steam
piston assemblies move through the cylinders, the
piston connectors lift the sealing strips and the sealing
strip guides reseat them. Action of the sealing strip is
shown in figure 4-22. View A shows the strip position
forward of the piston assembly. View B shows the
connector lifting the strip to permit the piston-shuttle
connector to pass under it. View C shows the guide
