Cylinder

Solid, bounded by a cylindrical and two parallel plane surfaces called bases; cla ified (1) according to the character of the cylindrical surface; (2) as right or oblique, as the elements of the cylindrical surface form right or oblique angles with the basal planes. In steam engine practice, the hollow cylinder has a piston fitting its bore, and the expansive force of steam moves the piston to and fro, and performs work. Engine cylinders are always of cast-iron.
