AI Technical Summary
Technical Problem
The existing fuel supply system suffers from poor fuel supply uniformity, slow response to changes in fuel flow, serious fuel leakage problems in the in-shaft fuel supply method, and fuel splashing and accumulating downwards in the oil slinger.
Method used
It adopts a dual-ring chamber fuel supply assembly and a baffled oil slinger structure, in which fuel is distributed circumferentially multiple times in the fuel supply path. The wedge-shaped baffle reduces fuel splashing, improves fuel uniformity, and avoids fuel leakage.
Benefits of technology
It improves the uniformity of the engine fuel supply system and the uniformity of the combustion chamber outlet temperature field, reduces the probability of hot spots in the combustion chamber, and improves fuel atomization.

Abstract
The application belongs to the field of power machinery, and discloses a kind of oil supply assembly-oil throwing disc structure, including oil supply assembly (1) and oil throwing disc (2);Oil throwing disc (2) is centrifugal oil throwing disc, and there are radial oil injection holes on the side surface of oil throwing disc evenly;Oil throwing disc (2) is disc-shaped as a whole, and the radial recessed cavity with inward opening is arranged on one side thereof, the opening of the recessed cavity is provided with wedge baffle, and the wedge baffle partially shields the opening of radial recessed cavity;The position of the radial recessed cavity of the oil throwing disc (2) corresponds to the position of the oil injection hole of the rear annular cavity of the oil supply assembly (1).The application adopts double-annular-cavity oil supply assembly and oil throwing disc structure with baffle, realizes multiple circumferential distribution of fuel in oil supply flow path, simultaneously weakens the influence of fuel splashing on fuel uniformity, effectively improves the uniformity of engine oil supply system, and improves the uniformity of combustion chamber outlet temperature field.
