DEFINITION

Classification: 137/834

(under subclass 803) Device provided with at least five passages joined at a zone common to all the passages, including a first passage permitting entry into said common zone of a power input stream of fluid, a second passage and a third passage permitting entry into said common zone of control input signals (i.e., stream of fluid or energy field), said second and third passages being substantially opposed to one another and substantially perpendicular to said first passage and the three passages thus forming approximately a letter "T"; and also including a fourth passage and a fifth passage permitting exit from said common zone of power output fluid, said fourth and fifth passages diverging substantially oppositely away from said first passage and said common zone and thus forming approximately a letter "V"; the overall arrangement of passages thus forming a "V" joined to a "T" at the common juncture of zone.

(1) Note. The common zone described is known as an "interaction chamber" or "interaction region", and is referred to in subclasses 811 and 823 above, as well as being the subject matter of subclass 839 below.

(2) Note. The arrangement defined permits a control-input signal to enter the interaction chamber via either the second passage or the third passage thereby to divert or deflect a stream of fluid that is entering the common zone via the first passage. The stream, which has been exiting via one of

the passages (i.e., either the fourth or the fifth) is thus caused to switch (in full or in part) to thereafter exit via the other of the passages (i.e., either the fifth or the fourth) until another control input signal causes another switch.
