Title: Fuel supplying device provided with rotary pump
Inventor: FRANK KURT
IPC: F04D29/70
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To suppress operating noise of a high frequency generated by a rotary pump by arranging a noise eliminating device of a fuel one-through type, upstream from a fuel inlet connecting part of a fuel pump. SOLUTION: A noise eliminating device l3 is formed of a porous vibration damping material in its inside, for example, it is formed of a foam material of continuous bubbles. As a result, only few fluidized resistance is not generated on fuel, and operating noise discharged from an inlet connecting part 3 is damped by dispersion of vibration. The noise eliminating device 13 is arranged in a front chamber so as to cover all cross sectional part of the inlet connecting part 3, and operating noise transmitted bypassing fuel in a pump 2 is prevented from discharging from the inlet connecting part 3 at a linear distance. The noise eliminating device 13 is expanded along all horizontal cross sectional surface of the front chamber, and it is brought into tightly contact with a side wall 8, and thereby, reflected operating noise can be damped.  It is thus possible to suppress operating noise of a high frequency generated by a rotary pump.
