Abstract

The invention relates to a washer for reducing noise and a system for reducing noise of wastegate valve apparatus by using the same. The system for reducing noise of a wastegate valve apparatus includes a bypass passage, a wastegate valve, an actuator and a link unit delivering the power of the actuator to the wastegate valve, may have a first link connected to the actuator, a third link connected to the wastegate valve, a second link provided with a rod disposed between the first link and the third link, wherein the second link includes a rod end ball bearing having a penetration hole into which a bolt member is inserted and a ball coupled to the penetration hole, and a joint connecting the rod and the third link, and a first washer disposed between the rod end ball bearing and the first link, wherein the first washer includes a support body, and an elastic member disposed between the first link and the support body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0127969 filed with the Korean Intellectual Property Office on Dec. 1, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a gasket for reducing noise and a system for reducing noise of a wastegate device by using the same, and more particularly, the present invention relates to a gasket for reducing noise and for reducing wastegate Noiseless system to reduce the noise generated at the connecting rod of the wastegate device. Background technique [0004] The wastegate device is adapted to control the rotation of the turbine of the turbocharger and thus the amount of intake air flowing into the combustion chamber by controlling the flow rate of exhaust gas according to the driving conditions of the engine. [0005] Generally, a wastegate device includ...
