Definitions

  • the present invention regards to a silencer for automobiles, architectural and other mechanical facilities, especially for automobi les.
  • the silencer is composed of a resonant room and its wall through which the exhaust gas passes. This is to remove the noise generated when an exhaust valve opens by offsetting the sound wave progressing to the right direction with the reflected sound wave progressing to the reverse direction in the silencer.
  • This invention is suggested to solve the problem of existing technologies. It provides the silencer with a natural and smooth exhaustion as well as an excellent removal of exhaust noise. Thus, it can fully satisfy the exhausting amount required by the engine or other industrial facilities even with a small volume, and can save the space and the cost a lot. It can give the vehicle designers a freedom to choose the space for the silencer. Most of all, the main purpose of this silencer is to facilitate the exhaustion enough to enhance the output of engine and to save the fuel considerably.
  • the silencer of this design is installed on the exhaust system of the mechanical structure.

  • multiple noise absorption guides are situated inside the body of the silencer consecutively at regular intervals.
  • the noise absorption guide has a hollow form, of which the inlet is situated to the inlet of the body and the outlet is to the outlet of the body.
  • the circumference of the above outlet is combined with the inside surface of the body.
  • the surface connecting the circumferences of above inlet and outlet is tilted to get farther from the inner surface of the body while it goes from the outlet to the inlet.

  • the screw element (30) makes the exhaust gas a strong whirl to pass through the body fast and smoothly. With this, a large amount of mixed air can quickly come into the engine to enhance its output. Moreover, it accomplishes nearly the complete combustion and improves the mileage. Meanwhile, the sound wave of exhaust noise comes into the body(l ⁇ ) and progresses straight. When it passes through the screw element (30), the sound is blocked and refracted by the twisted surface of the screw element(30) and the refracted sound wave is reflected on the tapered surface and returned to the source direction. The returned wave makes the offsetting interference with the incoming wave to be destroyed or naturally disappear in the space between the wall of body(l ⁇ ) and the tapered surface of noise absorption guide(20). In this way, the noise is removed.
  • this invention has many advantages. Through the twisted screw element installed in it, it induces the natural exhaustion of the gas. Moreover, with the screw element and the washer-type noise absorption guides that are protruded slantingly around the screw element, it removes the noises. Thus, it has nearly no exhaust pressure enough to enhance the mileage and to reduce the loss of output, minimizing the noises. It size is a little bit larger than the conventional muffler. So, it can be freely installed on any place of the vehicle when the vehicle is designed. With a small size, it is also light weighted. Thus, it can reduce the total weight of the vehicle, as well as many costs related with it.

Abstract

L'invention concerne un pot d'échappement pour automobiles, installations architecturales et autres installations mécaniques. Ledit pot d'échappement est constitué des composants suivants : un corps de type tuyau installé sur le système d'échappement de la structure mécanique et dont une extrémité forme l'entrée des gaz d'échappement et l'autre forme la sortie de décharge des gaz d'échappement ; des guides d'absorption de bruit multiples installés dans le corps du silencieux à des intervalles réguliers, l'un après l'autre, de l'entrée vers la sortie du corps ci-dessus. Le guide d'absorption de bruit est creux ; son entrée est située vers l'entrée du corps et sa sortie vers la sortie du corps. La circonférence de la sortie du corps est combinée avec la surface intérieure du corps. La surface reliant la circonférence de l'entrée et de la sortie du corps est inclinée et s'éloigne de la surface intérieure du corps, de la sortie vers l'entrée ; l'élément de vis formé en torsadant une plaque, passe à travers l'entrée et la sortie des multiples guides d'absorption de bruit et est fixé sur la circonférence d'entrée du guide d'absorption du bruit, à l'intérieur du corps.
