Triple and Quadruple expansion enginesare simply the results of high steam pressure, and more liberalexpansion. The engines from wnich these diagrams were taken belongto the slow or medium speed type. In reference to indicator cards in general it will be seenthat in many cases their lines do not reach that degree of excel-lence as shown in Fig. 152. The fault is often due to bad valve setting or poor valveconstruction, and it may sometimes be due to the indicatoritself, either of which may cause the steam line to be wavy from And Its Appliances. 269 start to finish. The usual reason assigned, however, is thepresence of water, which comes in such volume that its inertia. 3 3L° Fig. 153.
