  • Patent number: 8800598
    Abstract: Devices for conveying fuel are known having a conveying assembly and a pump holder holding the conveying assembly which has a receptacle for the conveying assembly and a holder connected to the receptacle via three damping elements. The damping elements damp the structure-born noise transmission from the conveying assembly to the adjacent components. The damping elements each have a cantilever section which projects starting from the receptacle into the region of the holder and runs in the radial direction and circumferential direction. The cantilever sections are designed as elastic spring arms, the axial deflection thereof in respect of a pump axis being able to exceed a maximum allowable value by means of external acceleration forces. The mechanical stresses occurring in the spring arms can lead to damage to the spring arms.

    Abstract: In a fuel supply apparatus for vehicles, a fuel pump is supported in a sub tank through cushioning members. Each cushioning member includes a plurality of resilient parts having a wavy shape in cross section in a radial direction and a plate width in an axial direction. The resilient parts thus support the fuel pump resiliently to absorb vibrations of the fuel pump caused in the radial direction, while withstanding the weight of the fuel pump and the reaction force generated upon fuel discharge operation of the fuel pump. The cushioning members are resin-molded unitarily with an inlet-side cover and an outlet-side cover which are fitted in the axial side ends of the fuel pump. The cushioning members have respective engagement parts which are fitted with the sub tank. The sub tank has stoppers which restrict the fuel pump from moving in the axial direction under a condition that the fuel pump is assembled with the sub tank.
