Abstract

Improved fluid logic elements are disclosed employing a laminar proportio fluid amplifier connected in a feedback arrangement. Logic functions such as AND, OR, and NOR as well as the flip-flop can be implemented with a reduced power consumption and signal to noise ratio relative to turbulent wall-attachment devices. In one embodiment, the outputs of a first laminar proportional fluid amplifier are input to a second laminar proportional fluid amplifier so as to decouple the operation of the first amplifier from a utilization circuit.
