Crank. This rotates the shaft of the engine and per- mits the change of rectilinear into circular motion. Eccentric. This forms a sort of crank which, as its name implies, does not turn around a true center. It opens and closes the steam ports in the valve chest by means of the eccentric rod which forms the connection between it and the slide valve. Setting the Slide Valve. The slide valve should be.
