GAS PRESSURE ADJUSTER WITH STRAIGHT ACTION AND SELF-HEATING Russian patent published in 2004 - IPC

FIELD: hydraulic and pneumatic engineering.

SUBSTANCE: device has outer body, vortex chamber of energy separation coaxial to it having ring channel for diverting hot flow and an assembly for adjusting cross-section of tangential nozzle input of compressed gas into chamber as well as utilizing ejector. Adjusting assembly, in form of valve, is made in form of servo of hollow cylinder longitudinally displaced by rod, on the side of diaphragm of input collector interacting with saddle and output cross-section of nozzle input by longitudinal tangential channels of a wall, which collector envelopes outer wall of valve, while channel for diverting hot flow to cold end of chamber and nozzle input body is by its output connected to collector for supplying hot flow into ejector, made in form of tangential channels in side wall of channel for diversion of cold flow, and behind ejector displacement channel and side branch of mixed flow a said servo of adjuster is placed with sensitive element, for example - piston, loaded on one side by output pressure of reduced gas, and on other side - by force of pressure from main spring or controlling gas.

EFFECT: higher operation reliability and adjustment precision due to effective self-heating and dynamic balance of locking couple.
