Embodiment Construction

[0029] Hereinafter, the noise reduction variable intake device will be described in detail with reference to the accompanying drawings.

[0030] In the exemplary embodiment of the noise-reducing variable air intake device, a magnet 31 is installed on the valve 20 or the duct body 11, and a steel member 32 is installed on the other of the valve 20 and the duct body 11 to keep the valve 20 In a position where the through-hole 11 a of the duct main body 11 is closed. A buffer member 33 that prevents sound from being generated when the pipe main body 11 is hit due to the valve 20 being closed is mounted on the valve 20 or the pipe main body 11 .

[0031] The air duct 12 serves as an inlet for introducing fresh air from outside the vehicle. The air duct 12 includes passages for air flow, and depending on the operating conditions of the vehicle, air may enter the engine through the passages in the air duct 12 , thereby reducing engine noise.

[0032] The duct body 11 is installed ...

Abstract

The present invention discloses a variable intake device including a valve configured to open a through hole formed at a duct main body to change the path of air introduced to the engine according to the engine RPM when the engine is driven at a high output, wherein the magnet Installed on either one of the valve and the piping body and a steel member on the other of them to keep the valve in a state where the through hole is closed, and a buffer member is installed on either of the valve and the piping body to prevent the There is a crashing sound when hitting the main body of the pipe.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of Korean Patent Application No. 2016-0128926 filed on October 6, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] Exemplary embodiments of the present disclosure relate to a variable intake device installed in a vehicle intake duct to change an air flow path according to engine RPM, and more particularly, to a noise-reducing variable intake device, It prevents the sound from being hit on the side of the duct body when the valve is opened or closed when the engine RPM is drastically reduced. Background technique [0004] There is known a variable intake system in which air is introduced into the engine and which can have different paths depending on the engine RPM. [0005] In the variable air intake system, when the vehicle engine is operating at low RPM, the path through which air is drawn into the engine from the outsi...
