Abstract
An elastic support system is disclosed for a fuel system of motor vehicles of the type equipped with a mixture-compressing internal-combustion engine and an electrically driven fuel pump, a fuel filter and an accumulator, in which case at least the fuel pump is to be arranged in proximity of the tank at the underbody. A roller vane pump is used as the fuel pump which operates with heavy pulsations and therefore, in addition to its mechanically caused operating noises, also generates pulsation noises. It therefore must be disconnected or isolated from the underbody with respect to vibrations. For this purpose, it is suggested by the invention to provide, between the fuel pump and a suspension member fastened at the underbody of the motor vehicle, a connecting element that is held at the fuel pump and can be suspended at the suspension member. The connecting element consists exclusively of rubber-elastic material and at least in the area between the fuel pump and the suspension member exhibits a low spring rate. The soft development of the connecting element ensures an effective disconnection of vibrations between the fuel pump and the underbody of the motor vehicle during use of the system.
