Public works . TYPICAL UNAFLOW STEAM CYLINDERCARD. AND INDICATOR. INSTALLATION IN THE PORTER AVE. PUMPING STATIONOF THE BUFFALO WATERWORKS. The pump derives its name from the fact that the steamentering the cylinder travels through it continuously in onedirection. The heat energy of the steam is utilized in thecylinder during the period of its admission, expansion andflow, the expanded steam being exhausted through ports oropenings uncovered by the travel of the cylinder piston whenmost remote from the point of admission. A typical cylinderis shown in the accompanying diagram. In this, the piston is shown at one end of the stroke andthe exhaust ports are uncovered. The arrow indicates the pathof the steam through the cylinder. There is practically nochange of temperature of the steam until the point of cut-offis reached. After this, expansion takes place with a constantdrop in temperature, and at this time condensation begins dueto the changing of heat into work. The cylinder head isjacketed with high steam, consequently no condensation takesplace o
