GAS-DISTRIBUTING VALVE Russian patent published in 2015 - IPC F16K11/85 F16K5/12 F16K5/04 

FIELD: machine building.

SUBSTANCE: gas-distributing valve contains body with input and two output nozzles, in which the flowrate holes are made, shutters located in the body and connected kinematically with the shaft and installed with radial clearance in relation to the shaft and output nozzles, with which they are in contact over similar surface of rotation. In the shaft ring lugs with shoulders are made, the shoulders enter the response through slots of the shutters' limiters. On the shoulders of the shaft ring lugs the pressing elements are fit installed, the elements are made out of resilient material in contact with the shutters' limiters. The shaft ring lugs are made in the transverse cross-section with rounding. The internal surface of the pressing elements in the transverse cross-section is made v with the external surface of the ring lugs.

EFFECT: increased operation reliability of the gas-distributing valves due to exclusion of the possibility of part collision prior to the valve operation.
