It will be noticedthat there is a supplementarypassage extending from the topof the valve chamber, around theoutside and joining the one going from the bottom of the cham-ber directly to the cylinder. This allows the steam to havetwo-passages, and with the same distance of port opening givesa length equal to twice the length of the valve strip; exhauststeam also follows the same path. It will also be noticed thatthe passage of the steam to and from the cylinder is more di-rect than that usually found in the slide or piston valve.
