Embodiment Construction

[0008] The positive and negative cups and barrels are directly and independently made into each single piece by cold stamping technology in advance, and a set of forward cups and barrels with different diameters are combined with another set of reversed cups and barrels with different diameters. Group 3 is installed on the intake pipe 1 through their respective bottom through holes, and the mouths of the forward cup and barrel group 2 and the reverse cup and barrel group 3 are opposite, and the forward and reverse cup and barrel groups are spaced apart from each other to form a contained and contained state , the gaps formed in between form a labyrinth circuit. On the intake pipe 1, densely distributed damping holes 4 are formed, and the intake pipe 1 is blocked outside the reverse cup and barrel group 3 with a head 5, and the sealing end cover 6 is fixed to the outermost mouth of the forward cup and barrel group 2; A fixed exhaust pipe 7 is installed on the end cover 6 .

Abstract

The invention discloses a labyrinth type silencer, belonging to the technical field of silencers. The labyrinth type silencer is characterized in that forward and reverse cup-shaped barrel groups with different diameters are arranged on a gas inlet pipe; the openings of the forward cup-shaped barrel group are opposite to that of the reverse cup-shaped barrel group; the forward and reverse cup-shaped barrel group bodies are arranged at interval to form containing and contained states, and gaps formed among the forward and reverse cup-shaped barrel group bodies form a labyrinth loop; and damping holes distributed densely are manufactured on the gas inlet pipe. The labyrinth type silencer has the advantages of simple structure, better manufacture technique, lower cost and better silencing effect.

Description

technical field [0001] The invention relates to a muffler and belongs to the technical field of mufflers. Background technique [0002] At present, although the structure of the muffler is not the same, there are generally defects such as complex structure, poor manufacturing process, and high cost. The damping space and diffusion space that the airflow passes through in the space are generally limited, so there is also the defect of poor sound attenuation effect. Contents of the invention [0003] The purpose of the present invention is to provide a labyrinth silencer to overcome the disadvantages of the existing silencer, such as complex structure, poor manufacturing process, high cost, and poor noise reduction effect. The above-mentioned defects that exist. [0004] The technical solution adopted by the present invention to achieve the above object is to adopt a labyrinth structure, that is, a group of forward cups and barrels with different diameters and another set ...
