FIG. 1 is a schematic view of an automotive fuel vapor intake manifold assembly according to the present invention.
Fig. 2 is a structural view of the resonance damper element according to the present invention.
Detailed Description
As shown in figure 1, the automobile fuel steam intake pipe assembly comprises a first joint 1, a circulating pipe 2, a three-way joint 3, a first branch pipe 4, a second branch pipe 6, a third branch pipe 8 and a second joint 9, wherein one end of the circulating pipe 2 is connected to the first joint 1, the other end of the circulating pipe is connected to an inlet of the three-way joint 3, a first outlet of the three-way joint 3 is connected to an inlet of the first branch pipe 4, a second outlet of the three-way joint 3 is connected to a fuel filling quantity limiting valve on a fuel tank, an outlet of the first branch pipe 4 is connected to an inlet of the second branch pipe 6, an outlet of the second branch pipe 6 is connected to an inlet of a resonance noise elimination element 7, an outlet of the resonance noise elimination element 7 is connected to an inlet of the third branch pipe 8, and an outlet of the third branch pipe 8 is connected to the second joint 9.
Further, the resonance noise elimination element 7 includes a first noise elimination cavity 701 and a second noise elimination cavity 702 which are fixedly connected, one end of the first noise elimination cavity 701 is provided with an air inlet port 703, and the inner diameter of the first noise elimination cavity 701 is larger than that of the air inlet port 703; an air outlet port 704 is formed in one end of the second sound attenuation cavity 702, and the inner diameter of the second sound attenuation cavity 702 is larger than that of the air outlet port 704; the first silencing cavity 701 is communicated with the second silencing cavity 702.
Further, the first muffling cavity 701 and the second muffling cavity 702 are both of a cavity structure.
Further, in order to be fixedly connected with the pipelines at the two ends better and increase the pulling-out force of the resonance silencing element 7 connected with the pipelines, barb structures are arranged on the air inlet port 703 and the air outlet port 704.
