Steam Engine, Transparent

1. Description
A steam engine operates in a two-stroke cycle
recognisable by the inward and outward motions
of the piston.
The outward motion of the piston is the working
stroke and is powered by steam pressure, which
is then transferred via the connecting rod to the
flywheel. The return motion of the piston is pro-
pelled in the simplest instance either by the en-
ergy stored in the flywheel or by using a "double
acting" piston whereby steam pressure is used
to push the piston in both directions.
The input of steam into the cylinder is controlled
by a slide valve.
