Robinsons Engine House 2: The images on this page are all taken in the middle chamber of the engine house. On this floor are the valve chests and the top of the cylinder.
This engine is unique in respect that it has two valve chests, one for live and the other for equilibrium steam. The idea behind this was to minimize heat loss from the live steam when it passed over the surfaces cooled by the outgoing steam.
