METHOD FOR DIGITAL-TO-ANALOGUE CONVERSION AND JET-PNEUMATIC DIGITAL-TO-ANALOGUE CONVERTER Russian patent published in 2022 - IPC F15C4/00 

FIELD: information technology.

SUBSTANCE: group of inventions relates to the field of converters of discrete and analogue signals, in particular to pneumatic digital-to-analogue converters. A method for digital-to-analogue conversion is based on representation of a number in a binary code, proportional to moments of force action of jets, and it consists in that plate 1 is installed with the possibility of change and registration of its rotation angle, is suspended on gas support 2. A set of nozzles is connected to digital circuit 3 according to increasing values of signal weight and is located widely spaced from the center of rotation of plate 1, according to their positive and negative values, from both sides of plate 1. Between reading nozzle 4 and supplying throttle 6, inter-throttle chamber 7 is located, connected to an input of power amplifier 8 and compensation nozzle 11. Force action of jets on plate 1 is performed with the same pressure in front of nozzles of circuit 3. Amplifier 8 is made pneumatic and membrane. Nozzle 11 and feedback nozzle 10 are located before or after amplifier 8, respectively.

EFFECT: group of inventions is aimed at simplification of setting and increase in the accuracy of conversion of discrete signals represented in a binary code into a continuous analogue signal.
