Fluid Binary Full Adder

The fluid binary full-adder has two fluid amplifiers, active elements 11 and 12 and two gates, passive elements 13 and 14.

A and B are the fluid pressure signals representing the two digits to be added. C(IN) is the incoming and C (OUT) the outgoing carry signal. S is the output signal indicating the sum. The output signal

of the passive And, interacting free jet device 13, is fed into the passive Or 14, the output signal of which is C(OUT). Active elements 11 and 12 are indicated by wide arrows representing the power jet.

Dots in front of a receiver mark stable positions of the jet. This is when equal signals at the control ports provide symmetric conditions. Thus, fluid amplifier 11 delivers the output signal AB + AB. This is used as one control signal for fluid amplifier 12. Its other control signal is the incoming carry signal C(IN) of the preceding binary order. Symmetric control produces output signal S. When only input signal C(IN) is present, fluid amplifier 12 propagates the carry signal via the Or 14 to output C(OUT).
