Silencing device

Abstract

The "article relating to the design" of this design registration application (hereinafter referred to as "the Application") is a device for attenuating and reducing exhaust noise, particularly low-frequency noise, generated from various heavy machinery such as backhoes and other large construction machinery and equipment, as well as generators and other devices (hereinafter referred to as "construction equipment, etc.") mainly used at construction sites, and functions as an exhaust pipe. The Application is mounted and fixed to the construction equipment, etc. by a substantially triangular flange (hereinafter referred to as "flange"), and one end of the Application is connected to the exhaust port of the construction equipment, etc. using a heat-resistant duct. The mounting position and range in which the Application is mounted vary depending on the type of construction equipment, etc., but the Application is constructed of multiple pipe members fixed together via a flange, and the fitting width between the large-diameter pipe and the small-diameter pipe can be expanded or contracted, making it easy to install according to the width and length of the mounting location on the construction equipment, etc.
