    Abstract: The present invention relates to a variable valve mounted on a pipe to be opened or closed in accordance to pressure of discharged gas. The variable valve includes a closing plate mounted inside the pipe and having an opening hole perforated to block the flow of the discharged gas; a spring manufactured with elastic material and coupled to the closing plate; and a gate mounted to block the opening hole by elasticity of the spring, wherein the spring has two leg portions coupled to the closing plate from each end and a connection portion connecting the leg portions and coming in close contact with the gate, and the leg portions are twisted in the connection portion in different directions. Different from a conventional structure wherein a shaft, which is a rotary shaft of the gate, is disposed outside the pipe, the gate is opened and closed inside the pipe, thereby considerably reducing noise transferred outside when opening and closing the gate. The gate occupies small portion inside an internal space of a muffler, thereby reducing sizes of both the variable valve and peripheral parts.

    Abstract translation: 本发明涉及一种安装在要被打开或关闭的管道上的可变阀，该可变阀根据排放气体的压力。 可变阀包括安装在管内的封闭板，并具有穿孔以阻塞排出气体的流动的开孔; 用弹性材料制成的弹簧，并连接到封闭板上; 以及安装成通过弹簧的弹性阻挡开口孔的门，其中弹簧具有从每个端部联接到封闭板的两个腿部和连接腿部并与门紧密接触的连接部分，并且腿部 部分在不同方向上在连接部分中扭转。 不同于传统的结构，其中作为门的旋转轴的轴设置在管的外侧，门在管内被打开和关闭，从而大大减少了打开和关闭门时传递到外部的噪音。 门在消音器的内部空间内占据小部分，从而减小可变阀和外围部件的尺寸。

    Abstract: The present invention relates to a tail pipe for a silencer which improves the outer appearance and prevents air flow noises from occurring. The tail pipe for a silencer according to an embodiment of the present invention includes: an inner surface which is included in the rear side of a rear discharge pipe connected to the rear side of the silencer, is used as an outlet to discharge exhaust gas, and faces the hollow gap; an outer surface which is the opposite surface of the inner surface; one or more plates forming the inner and outer surfaces; a space which is formed between the inner surface and the outer surface and is surrounded by the plates; an accommodating hole formed in the inner surface; a barrier wall which is mounted in the space and protrudes to the hollow space through the accommodating hole. The barrier wall can collect he soot from the exhaust gas.
