REDUCER AND GAS FLOW REGULATION METHOD Russian patent published in 2014 - IPC G05D16/06 B63C11/32 F16K31/12 

FIELD: machine building.

SUBSTANCE: reducer comprises a case with three chambers divided by walls: a high-pressure chamber, a reduced pressure chamber and a regulation chamber, a partition coupled with a movable plunger diving the regulation chamber into a piston cavity and an annular cavity, a valve which is connected with the plunger, set in the high-pressure chamber, fitted with a sealing element interacting with a seat in the wall, the first channel connecting the reduced pressure chamber with the piston cavity of the regulation chamber, the second channel with a check valve connecting one of the regulation chamber cavities with the environment, the third channel with a regulated throttle connecting the high-pressure chamber with the piston cavity. The method involves the supply of gas to the piston cavity of the high-pressure chamber, delivery of gas to the reduced pressure chamber and to the consumer, it is possible to change the flow and pressure of gas delivered to the consumer, bleeding of gas from the piston cavity into the environment through the second channel.

EFFECT: reduced dimensions and weight of a reducer with low amplitude of pressure fluctuations.
