MODULAR FUEL-FEED SET OF VEHICLE ENGINE FUEL SYSTEM Russian patent published in 2001 - IPC

FIELD: transport engineering; internal combustion engine fuel system. SUBSTANCE: proposed modular fuel- feed set has fuel tank accommodating electric fuel pump and perforated shell installed with clearance relative to inner part of fuel tank wall. Clearances between part of shell outer surface and fuel tank walls opposite to shell surface are of different sizes. Shell can be made in form of common part secured on walls of fuel tank by means of vibration damping members. Common part is made in form of hollow perforated capsule. Shell can be made in form of separate local members arranged parallel and/or with tilting relative to fuel tank walls and secured on these walls by means of vibration damping members. Shell can be provided with partitions. Shell, partitions and vibration damping members can be made of metallic porous gauze material. Partitions can be located in antinode zones of lower natural oscillation modes of fuel tank space volume. EFFECT: improved comfort by reducing noise of modular fuel-feed set. 6 cl, 2 dwg
