Benefits of technology

The present invention provides a variable valve for reducing noise in an exhaust gas system. This valve can be installed at any position along the exhaust line, minimizing abnormal noise and ensuring maximum efficiency. The valve uses a leaf spring with a simplified structure, making it easy to install and effective in reducing noise. Ultimately, this valve helps to create a quieter and more efficient exhaust system.

Problems solved by technology

However, the position where variable valves of the related art is installed is limited the muffler, thus causing difficulty in effectively reducing noise generated at various positions on the exhaust line.
Further, the variable valves have complicated parts, and abnormal noise and touching noise are generated by the coil spring and the operation of the gate, respectively, in the operation of the variable valves.

Abstract

A variable valve for an exhaust pipe that includes a housing disposed within an exhaust line and a partition that is fixed within the housing and divides the inside of the housing into a first exhaust gas channel and a second exhaust gas channel. A gate is disposed within the housing to selectively open and close the second exhaust gas channel and a leaf spring connects the partition with the gate and opens and closes the gate using pressure of an exhaust gas.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2012-0142062 filed in the Korean Intellectual Property Office on Dec. 7, 2012, the entire contents of which are incorporated herein by reference.BACKGROUND[0002](a) Field of the Invention[0003]The present invention relates to a variable valve for an exhaust pipe. More particularly, the present invention relates to a variable valve for an exhaust pipe that reduces exhaust noise and improves the output of an engine by opening and closing the channel of an exhaust pipe based on the output of the engine of a vehicle.[0004](b) Description of the Related Art[0005]In general, exhaust gases produced by the engine of vehicles are exhausted by an exhaust system and the exhaust system includes an exhaust line that guides exhaust gases to the rear of a vehicle and a muffler disposed within the exhaust line and that reduces exhaust noise.[0006]The muffler may be equ...
