VORTEX PRESSURE CONTROLLER Russian patent published in 2011 - IPC G05D16/00 

FIELD: machine building.

SUBSTANCE: vortex pressure controller of gas with positive feedback consists of supplying pipeline connected to cylinder of temperature division via unit of gas flow control by means of channel and connected with lateral pipeline via diaphragm. The lateral pipeline is connected with a pilot device. Also, positive feedback is facilitated in a "hot" circuit by means of the channel between the pipeline and the cylinder of temperature division which contains a cross piece with profiled blades gradually straightening gas flow and a device for overflow of "hot gas" after the cross piece into centre of a "cold" vortex on axis of the cylinder. The unit for control of an inlet flow contains at least two nozzles uniformly arranged along circumference and profiled nozzle gates corresponding to nozzles and rotating around fixture axes for control of flow section of each nozzle. At the "hot" end of the temperature division cylinder there is installed a ribbed head with channels of "hot" gas overflow in walls. These channels are connected with pipes positioned in the channel around the cylinder for temperature division to facilitate outlet of overflow part of "hot" gas from the cylinder into a gas ejector with its outlet connected to the lateral pipeline. The vortex gas pressure controller additionally has a unit for control of outlet flow. The unit is equipped with at least two "shutters" uniformly distributed along circumference and rotating around fixation axes for control of flow section of the diaphragm. Ribs on the head are screwed, while the pipes connected with "hot" gas overflow channels are made as spiral ribbed pipes.

EFFECT: improved operational characteristics of controller, raised effect of temperature division.
