FUEL FEED DIRECTLY CONTROLLED VALVE TO CIRCUIT FOR FUEL FLOW INJECTION Russian patent published in 2004 - IPC

FIELD: systems for fuel flow injection to turbojet engines.

SUBSTANCE: valve includes unit for controlling position of valve rod. Said unit includes commutatorless motor inserted into valve housing and connected with device for fuel distribution. Commutatorless motor rotates around symmetry axis and drives mechanical reduction gear. The last is arranged in housing of valve and it includes inlet shaft and outlet pinion or outlet shaft for transmitting motion from reduction gear. In the result it provides transmission of rotation of electric motor to valve rod in order to realize respective movement of said rod that causes change of matching degree of first and second openings of sleeve one with another. Inlet opening for supplying fuel has constant flow-through cross section determined in direction normal relative to cranking axis of valve rod.

EFFECT: enhanced operational characteristics of valve.
