HYDROMECHANICAL FUEL FEED GOVERNOR, GOVERNOR FUEL METER AND TURBOMACHINE EQUIPPED WITH SAID GOVERNOR Russian patent published in 2008 - IPC F02C9/26 

FIELD: mechanical engineering; turbomachines.

SUBSTANCE: proposed hydromechanical fuel feed governor is designed for delivery of fuel into turbomachines by means of fuel meter containing tachymetric balancer on base of rocker turning around axle under action of at least first force F1 applied by control rod of fuel meter through first elastic element. Governor contains additionally tie-rod connected with control piston applying force F4 to said balancer rocker by means of second elastic element, directed opposite to first force F1, to provide additional opening of fuel meter at changing over from first law of acceleration of engine to its second law of acceleration. Such design of hydromechanical governor and also meter and turbomachine makes it possible to use one and the same meter in realization of two different types of acceleration laws and provide possibility of changing over from one acceleration law to other law without excessive or insufficient fuel flow rate.

EFFECT: improved operation.
