Along eb, the steam would be passing from thesteam chest to the cylinder, the pressure being practically constantbecause of the comparatively enormous storage space in the boiler,while the piston moved outward, doing work. At 5, the supply ofsteam would cease, while communication would be immediatelyopened with the atmosphere or the condenser, causing the fall ofpressure along ht. The piston would then make its return stroke,the steam passing out of the cylinder at practically constant pressurealong td^ and at c? the position of the valve would again be changed,closing the exhaust and opening the supply and giving the instan-taneous rise of pressure indicated by de. 424. Expansion. This has been shown to be an inefficient cycle(Art. 417), and i
