JET DEVICE FOR CALCULATION OF SIGN OF DERIVATIVE

摘要

FIELD: automation equipment, in particular, for extreme regulation. SUBSTANCE: device has proportional jet amplifier, which control channels are connected to each other by communication lines, which has pneumatic resistors and pneumatic capacitor. Connection point of communication lines is connected to input pressure. Goal of invention is achieved by connection of connection point of communication lines and input pressure channel to amplifier power supply channel by additional communication line. EFFECT: increased regulation range, increased sensitivity. 1 dwgl
