Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve.

Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings. The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the ...
Early spark arrestors were simply iron wire screens installed within the stack. However, the screen reduced the rate at which smoke and steam could escape from the boiler. As well, embers caught by the screen further reduced available space for the passage of steam, and smoke and heat generated by the burning embers rapidly melted the wire screen.
The first kind is the steam lap, which is the amount by which the valve overlaps the steam port on the live steam side of the piston or slide valve (i.e. the distance the valve needs to move to just begin to uncover the port).
