INDIRECT ACTION PRESSURE ADJUSTER WITH SELF-HEATING FEATURE Russian patent published in 2005 - IPC

FIELD: hydro-pneumo-automatics.

SUBSTANCE: device has outer cylindrical body, vortex chamber coaxial to the latter for energy separation with circular channel for intake of hot flow and assembly for adjusting cross-section of tangential nozzle intake of compressed gas into chamber, positioned between diaphragm and chamber, and also utilizing ejector, while adjusting assembly, valve in particular, is made in form of diaphragm body moved in longitudinal fashion by servo rod, and interacting with outlet cross-section of nozzle intake via longitudinal tangential channels on the wall of cold end of vortex chamber, enveloping outer wall of valve, while channel for intake of hot flow to cold end of chamber by its outlet is connected to inlet of hot flow into ejector, while outer cylindrical body with side inlet of compressed gas and shut on the side of outlet of servo rod and hot end of vortex chamber has a spin diffuser directed along hot flow, with turbulence promoter, intermediate wall, held in flange groove of outer body, and also - outlet extending wall in such a way, that in ring-shaped area, forming an inlet collector across from side inlet of compressed gas, coaxially to outer body ejector pipes rigidly connected to walls are positioned with nozzles for outlet of hot flow in parallel to output of cold flow from diaphragm. Rod, mounted strictly along axis of vortex chamber, on the side of output of cold flow by ball support is connected to intersection of body of diaphragm and valve.

EFFECT: higher reliability, higher durability, higher efficiency.
