JET DEVICE FOR CONTROLLING PNEUMATIC CYLINDER Russian patent published in 2009 - IPC G05B19/44 

FIELD: physics; control.

SUBSTANCE: present invention pertains to automation equipment and can be used in automatically controlled pneumatic systems. The outcome is achieved through that, the said jet device has a pneumatic cylinder, distributor, pneumatic amplifier, RS flip-flop, made from jet discrete monostable elements, controlled by "Start" and "Stop" buttons. The proposed device differs from existing devices in that, it has a complement flip-flop, which switches when a logic-0 level signal applied to its complementing input, as well as an AND-fluid gate and a tuning throttle. The discharge line of the distributor is connected to the input of the tuning throttle and the complementing input of the complement flip-flop. The output of the RS flip-flop, set to the logic-1 level when the "Stop" button is pressed, is connected to the set input of the complementing flip-flop. The second output of the RS flip-flop is connected to the input of the AND-element. The output of the complementing flip-flop, set to the logic-1 level when a logic-1 level signal is applied to its set input, is connected to the second input of the AND element. The output of the AND element is connected to the input of the pneumatic amplifier, and the output of the tuning throttle opens to the atmosphere.

EFFECT: simpler design, increased reliability, more functional capabilities.
