TYPES OF SLIDEVALVES. Slide valve of theBayley engine. A flat valve ridingunder a balanced pressure plate is held in place bystays against the steam chest. 178. PARSONS STEAM TURBINE. Steam is admitted at thegovernor valve and arrives at the chamber, A, at the small end of the. revolving part of the turbine. The steam passes along to the rightthrough the turbine blades, passing through a series of fixed bladeswhich deflect it in one direction, thence striking the moving blades of 86 STEAM POWER APPLIANCES. the turbine which deflect it in the opposite direction, and so on. Inthis way the current of steam impinging upon the moving bladesdrives them around. The areas of the passages increase, progressingin volume corresponding with the expansion of the steam. On theleft of the steam inlet are revolving balance pistons, CCC, one cor-responding to each of the cylinders in the turbine. The enteringsteam at A presses equally against the revolving part of the turbineand against the first balancing piston. When it arrives at the passage,E, it presses against the next larger section of the revolving part of theturbine and also against the next largest balancing piston, connectionbetween the two being secured by the passage, F.
