È stato dotato di quattro valvole, i motori della ffl ir York hanno solo due; e, inoltre, che mentre la parte anteriore dei motori di Minneapolis wassheld da colonne rotonde verticali, vi è un telaio a Y invertito su ogni lato dei New Yorks. Anche i diametri dei cilindri sono diversi, ma, con le eccezioni che abbiamo già notato, l'aspetto generale dei motori è praticamente lo stesso. Per quanto riguarda i dettagli delle dimensioni, le valvole a pistone sono utilizzate esclusivamente; hanno un diametro di 16 poll. Per il cilindro ad alta pressione, con un diametro medio

The diameters of the cylin-ders are also different, but, with the exceptions which we havealready noted, the general appearauce of the engines is practi-cally the same. Regarding the details of the dimensions, piston-valves areexclusively used ; they have a diameter of 16 in. for the high-pressure cylinder, with a mean diameter for the low-pressurecylinder of 29A in. All the valves are driven by double-barStephenson links. The intermediate and low-pressure cylin-ders are jacketed on the sides and bottoms, while the high-pressure cylinders are fitted wilh a lining or wearing cylinderof hard cast iron. All of the pistons are of cast steel. As wehave already said, the cylinders are carried by invertedY frames made of cast steel, to which the cast-iron guides arc.
