NOVEL PISTON VALVE for a steam engine. A sideelevation, partly in section, of the valve and its casing, and a longitu-dinal sectional elevation. Ihevalve consists principally of a re-Hef valve held seated by a spring,but exposed at the opposite sideto the pressure of the steam, sothat in case of excessive pressure,suction, or vacuum, the enginebeing in motion and steam shutoff, the valve will lift, and steamor hot vapor and gases will enterand destroy compression and vac-uum, by way of the aperturesunder the valve leading to theexhaust, as we
