Problems solved by technology

[0002] After being pressurized by the supercharger, the air blown out from the outlet of the pressure casing has a strong pressure and flow velocity. When it passes through the long pressure casing flow channel, it will produce squealing and noise, which will cause the supercharger to vibrate abnormally and affect the engine. normal work

Embodiment Construction

[0008] Such as figure 1 , the present invention comprises a cylindrical shell 1, an inner cylinder 2 is housed inside the cylindrical shell 1, and two raised rings 3 and 4 are arranged on the waist of the inner cylinder 2, and the raised rings 3 and 4 connect the inner The cavity formed by the cylinder 2 and the cylinder shell 1 is divided into two independent annular cavities. The upper part of the inner wall of the cylindrical shell 1 is provided with internal threads, the bottom of the internal threads is provided with chamfers, the bottom of the inner cylinder 2 is provided with chamfers, and the outside of the raised ring 3 is provided with external threads.

[0009] When in use, just install the muffler at the air outlet of the pressure shell. When the sound wave is introduced into the muffler along with the air from the air outlet of the pressure shell, the energy of the sound wave will be greatly weakened after passing through the two closed cavities. The noise is...

Abstract

The invention relates to a silencer for an air outlet of a pressure shell, which is simple in structure, convenient in manufacture, and capable of effectively reducing noise, avoiding abnormal vibration of turbocharger, and assisting the turbocharger in operating normally. The silencer comprises a tubular outer shell, an inner tube is mounted in the tubular outer shell, an upper convex ring and a lower convex ring are arranged at the waist of the inner tube, a cavity formed by the inner tube and the tubular outer shell is divided into two independent annular cavities by the two convex rings, an internal thread is arranged on the upper portion of the inner wall of the tubular outer shell, the lower portion of the internal thread is chamfered, the inner side of the bottom end of the inner tube is chamfered, and an external thread is disposed on the outer side of the inner tube at a position close to the upper convex ring.

Description

technical field [0001] The invention relates to a pressure shell of a turbocharger, in particular to a muffler for an air outlet of the pressure shell. Background technique [0002] After being pressurized by the supercharger, the air blown out from the outlet of the pressure casing has a strong pressure and flow velocity. When it passes through the long pressure casing flow channel, it will produce squealing and noise, which will cause the supercharger to vibrate abnormally and affect the engine. normal work. Contents of the invention [0003] In view of the above problems, the present invention provides a muffler for the gas outlet of the pressure shell, which has a simple structure, is easy to manufacture, can effectively reduce noise, and helps the supercharger to work normally. [0004] Its technical solution is as follows: pressure shell gas outlet muffler is characterized in that it includes a cylindrical shell, and an inner cylinder is installed inside the...
