FEEDING AND DISCHARGING DEVICE FOR INJECTOR Russian patent published in 2017 - IPC F02C7/232 F16K17/18 F16K17/196 

FIELD: machine engineering.

SUBSTANCE: feeding and purge device (1) for a nozzle of a turbomachine chamber, which comprises: a tube (2) with a first opening (3) and a second opening (4), a blocking system (5) to block the tube, allows to control the passage of fluids into the tube (2). At that, the blocking system (5) is arranged with the possibility to provide the flow of fuel from the first opening (3) to the second opening (4) only from the first pressure of said fuel, for passage of fuel feed. At that, the blocking system (5) is also configured to provide the air flow from the second opening (4) to the first opening (3) only from the second pressure of said air, for the passage of the purge air with the second pressure being greater than the first pressure. Also, an assembly of a turbomachine, a nozzle for a combustion chamber of the turbomachine, and the turbomachine comprising a combustion chamber nozzle, are provided.

EFFECT: invention makes it possible to develop simple and compact device, which is made with possibility of adjustment of both fuel and purge air supply, which allows to provide complete blowing.
