JET-PNEUMATIC PRELIMINARY AND DIFFERENTIATION UNIT Russian patent published in 2022 - IPC G05B11/50 F15B11/76 

FIELD: pneumatic automatic regulators.

SUBSTANCE: invention relates to the field of pneumatic automatic regulators. The jet-pneumatic block of preliminary and differentiation is an equilibrium bridge based on the force action of the jets and consisting of a plate suspended on a gas support, on one side of which there is an input inertial link, including a variable resistance, a constant volume tank, a consumable exact repeater and a nozzle, oriented perpendicular to the plate, and on the other hand, a reading unit for the angle of rotation of the plate, made in the form of a throttle of the "nozzle-shutter" type, pneumatic membrane power amplifier, covered by two compensation nozzles, forming a regenerative feedback with an amplification factor greater than one. Moreover, to implement the control law during the preliminary operation, an inlet pressure source is connected to the zero point displacement nozzle, and to implement the control law during the differentiation operation, a source with a different pressure is connected.

EFFECT: technical the result is an expansion of the field of application of the block when implementing the laws of anticipation and differentiation due to the use of a consumable inertial link in a linear compensation scheme based on the force action of the jet on a movable barrier made in the form of a plate.
