Oscillating
Steam Engine

This style steam engine employs the cylinder as the steam valve.
It operates on the same principle as the locomotive steam engine.
Steam from the boiler enters the power manifold and is and is
admitted to the top end of the cylinder when the cylinder port aligns
with the manifold port.  The steam presses the piston downward,
driving the flywheel around one half turn.
At the end of the stroke the cylinder shifts, exposing the top port
to the exhaust manifold.  The expended steam is
released.
At the same time, the bottom cylinder port, aligns with the power
manifold, admitting steam to the bottom end of the cylinder.  This
presses the piston upward, driving the flywheel around another half turn.
At the end of the stroke, the bottom port aligns with the exhaust
manifold, releasing the expended steam.
Due to its exceedingly simple construction,
this type of engine is popular in working toy steam engines, including
one I had as a kid.  An
even simpler type employs power in only one direction, relying on flywheel
momentum to carry the piston around for the remainder of the
cycle.  This is called a single acting engine.  The
type illustrated here is a double acting engine.
