ABSTRACT:
A sequential inhibitor (NOT) fluid logic device has a control input (a), a supply input (b), and an output (c). The output signal is terminated through output (c) from supply input (b) only when a control signal at control input (a) precedes a supply signal at supply input (b). The device includes a series of three plate members defining a connected cavity and chamber. An arrangement of valve seats in the cavity and chamber cooperate with a poppet and diaphragm. The area of the seats cooperative with the diaphragm and poppet insure the sequential operation of the device. An exhaust passage (d) may be actively integrated into a circuit utilizing the device to provide a combined OR fluid logic device and sequential inhibitor having an input (d), a supply input (b), a control input (a) and an output (c).
