Diesel engines for land and marine work . Fig. 25.—Jointed Valve Lever. the rings is a conically-shaped piece, in the periphery ofwhich is about the same number of channels as thereare holes in the rings, and these channels, which may be fromone-sixteenth to one-twentieth of an inch deep, form aseries of nozzles, through which the fuel has to pass, aftergetting through the holes in the rings. It then enters thecylinder by the expanding orifice, which is made of steel, theguides for the needle valve being of cast iron. The annular 72 DIESEL ENGINES FOR LAND AND MARINE WORK space C is always in direct connexion with the injectionair reservoir as soon as the valve on the reservoir is opened,and the air enters the space near the top through anotherpipe and a cylindrical hole in the same casting as that for the.

The space C is thus always subjected to the highpressure of the injection air, and immediately the needlevalve lifts, the fuel is forced through the pulveriser by the airin the form of a very fine spray, and combustion at once CONSTRUCTION OF THE DIESEL ENGINE 73 takes place. A small cock 31 is provided having con-nexion with the inlet pipe and serves the purpose of a test
