The invention discloses a fuel distributor, which comprises a main oil passage valve assembly, an auxiliary oil passage outlet (1), an auxiliary oil passage valve assembly (2), a main oil discharge port (9) of the fuel distributor, and a main oil passage outlet ( 15), fuel inlet (18), solenoid valve (19), the main oil circuit valve assembly includes the main oil circuit spring seat cavity (5), the main oil circuit spring seat (6), the main oil circuit oil discharge port (8), Main oil circuit spring (11), main oil circuit valve sleeve (12), main oil circuit spool (14). Compared with the previous products, the fuel distributor has the characteristics of more precise, fast and reliable control, so as to achieve the purpose of distributing fuel more reasonably and effectively, and there will be no unstable pressure in the combustion chamber when cutting fuel.
Description
technical field [0001] The invention belongs to engine accessories and relates to the structural improvement of a fuel distributor. Background technique [0002] At present, most of the fuel distributors used in aero-engines mainly rely on the mechanical hydraulic system to control the opening and closing of the main and auxiliary oil circuits. The control accuracy and reliability are relatively low, and the general mechanical structure has unstable pressure in the combustion chamber when cutting oil. disadvantages. Contents of the invention [0003] Purpose of the present invention: to design a more accurate, fast and stable fuel distributor, thereby improving the working reliability of the whole engine fuel system. [0004] The technical solution of the present invention: a fuel distributor, comprising a main oil circuit valve assembly, an auxiliary oil circuit valve assembly 2, an auxiliary oil circuit outlet 1, a fuel distributor main oil discharge port 9, a main oil ...
