JET-PNEUMATIC SEMI-PROPORTIONAL REGULATOR Russian patent published in 2022 - IPC G05B11/44 

FIELD: automatic systems.

SUBSTANCE: invention relates to the field of automatic control systems, in particular to pneumatic automatic regulators. The device consists of a proportional regulator and a node for forming a control command to turn off the regulator when the controlled value and its speed deviate from the task. The output of the jet-pneumatic proportional regulator is connected via a disconnecting relay with two parallel jet-pneumatic threshold elements. In this case, the first threshold element includes nozzles located opposite to the sensitive element (the plate) connected to the output of the regulator and to the threshold element of the error sign, and the second threshold element contains nozzles connected to the speed sign detection unit.

EFFECT: increase in the speed of regulation by using a compensation scheme in a semi-proportional regulator based on the force action of the jet on a movable barrier.
