which opens and closes a passageway by sliding over a port. (b) A
particular kind of sliding valve, often used in steam engines for
admitting steam to the piston and releasing it, alternately, having a
cuplike cavity in its face, through which the exhaust steam passes. It
is situated in the steam chest, and moved by the valve gear. It is
sometimes called a D valve, -- a name which is also applied to a
semicylindrical pipe used as a sliding valve.
In the illustration, a is the cylinder of a steam engine, in which
plays the piston p; b the steam chest, receiving its supply from the
pipe i, and containing the slide valve s, which is shown as admitting
steam to one end of the cylinder through the port e, and opening
communication between the exhaust passage f and the port c, for the
release of steam from the opposite end of the cylinder.
