In order to securethe greatest work from steam in the cylinder it is neces-sary to maintain its temperature as near that of the tem-perature at which it left the boiler as possible. This pointis duly recognized by the designers of this cylinder andprovided for by including air spaces between the enter-ing hot steam and (comparatively cool) exhaust steamand by keeping the live steam close to the cylinder, main-taining a hotter cylinder than is possible with the ordi-nary design, insuring a high initial pressure of steam foreach admission-to the cylinder. The valve is of insideadmission, consequently the exha
