A valve assembly for vehicle exhaust system

The utility model relates to a valve assembly for a vehicle exhaust system. The valve assembly comprises an exhaust component main body for limiting an exhaust gas flow path and a baffle plate which is arranged between a minimum flow position and a maximum flow position and pivots in the exhaust gas flow path. And at least one bushing support baffle for rotational movement about an axis relative to the exhaust component body. In one example, a damper is positioned radially between the bushing and the baffle and defines an inner diameter that is less than an outer diameter of the bushing. In another example, the damper is attached to the baffle such that the distal edge is not attached to the distal edge of the baffle such that when the baffle returns to the minimum flow position, the damper first contacts the exhaust component body and then the baffle contacts the damper. 本实用新型涉及一种用于车辆排气系统的阀组件，包括限定废气流动路径的排气部件主体以及安装成在最小流量位置与最大流量位置之间在排气流动路径中枢转的挡板。至少一个轴衬支撑挡板，用以相对于排气部件主体绕轴线进行旋转运动。在一个示例中，阻尼器径向地定位在轴衬与挡板之间并且限定内径，该内径
