Description

technical field [0001] The invention belongs to the field of aero-engine fuel accessories, and relates to an aero-engine fuel control technology, in particular to a hydraulic stability adjustment device composed of a piston damper and a variable throttling nozzle. Background technique [0002] The fuel adjustment device controls the fuel output by sensing typical operating parameters such as speed and pressure, and the output flow will fluctuate instantaneously with the internal adjustment of the device. At present, the fuel adjustment device adopts the direct output flow method, which has a fast response speed, but the output flow fluctuates greatly, that is, the stability is poor; another product uses an electromagnetic control valve for stability adjustment, but it is susceptible to electromagnetic interference and has a reliable lesser problem. Contents of the invention [0003] The object of the present invention is to propose a hydraulic stability adjustment device ...
