    • The present invention relates to an exhaust gas recirculation (EGR) valve for a vehicle and, more particularly, to an EGR valve for a vehicle which is capable of simply and efficiently controlling a flow of exhaust gas which flows in through the EGR passage to an engine, and a fresh air in the outside which is related. The present invention comprises the following: a fresh air passage; an EGR passage which is connected to the fresh air passage; a valve unit which is prepared to selectively block the part of the fresh air passage according to the open and close status of the EGR passage while opening and closing the EGR passage; wherein the valve unit comprises a first valve which opens and closes the EGR passage; a second valve which is prepared to have different alignment angle with the first valve, and positioned in the one side of the first valve. The second valve provides the EGR valve which is prepared not to selectively interfere the flowing of the fresh air in the fresh air passage by moving together with the first valve.
    • 本发明涉及一种用于车辆的废气再循环(EGR)阀,更具体地,涉及一种用于车辆的EGR阀,其能够简单且有效地控制通过EGR通道流入的废气流到 发动机和外界新鲜空气相关。 本发明包括:新鲜空气通道; 连接到新鲜空气通道的EGR通道; 阀单元,其被设计成在打开和关闭EGR通道的同时根据EGR通道的打开和关闭状态选择性地阻塞新鲜空气通道的一部分; 其中所述阀单元包括打开和关闭所述EGR通道的第一阀; 第二阀,其准备与第一阀具有不同的对准角,并且位于第一阀的一侧。 第二阀提供EGR阀,其通过与第一阀一起移动而不选择性地干扰新鲜空气通道中的新鲜空气的流动。
