DEFINITION

Classification: 137/838

(under subclass 834) Device provided with a plurality of fourth passages or a plurality of fifth passages, the number of passages diverging away from said common zone permitting fluid to exit from said zone being three or more, or provided with fourth and fifth passages that come to a second common zone downstream of the first common zone.

(1) Note. In the case of the rejoined outlet passages, one of the passages is usually longer than the other so that a pulse of fluid through the longer passage will be delayed in its arrival at the second zone relative to the pulse through the shorter passage.
