^ the steam pipe a tothe steam chest b, and from there passes through b d andb d^ alternately above and below the piston, the exhauststeam passing out through the pipe c. The expansion valveor plug in b is moved, as we have just explained, by a spi-ral spring f and a double-ribbed cone r. This cone… … movable up and down on the spindle KL, which is made torevolve by the gear wheels H, K. The governor MM, whenthe velocity increases, raises r and thus diminishes thesteam entrance, while, when the velocity decreases, r islowered, and thus the supply of steam increased. Moreover,the weight of r is…
