Abstract: PURPOSE: An EGR valve assembly is provided to exactly control the amount of exhaust gas, and to prevent the temperature of the exhaust gas from increasing. CONSTITUTION: An EGR valve assembly comprises a motor, a valve rod, and a valve sheet plate. The motor is rotated based on the control of an electric control unit. The motor is formed into the cylindrical shape, and comprises a rotary member, which comprises screw threads on an inner surface. The valve rod moves up and down by being supplied with the torque of the motor. The valve rod comprises a screw part, in which the screw threads are formed with facing the screw threads of the rotary member. The valve sheet plate is installed in a lower part of the valve rod, and opens/closes a second exhaust gas path. One part of the valve rod is screwed inside the motor.

Abstract: 본발명은 EGR 밸브조립체에관한것으로, 하부에배기가스가유입되는유입구가형성되고, 일측에상기배기가스가배출되는배출구가형성되며, 상기유입구와배출구사이에는제 1 및제 2배출가스유로가형성되는하우징, 상기하우징에결합되어상기제 1 및제 2배출가스유로사이를개폐하는 EGR 밸브및 상기하우징과 EGR 밸브사이에설치되는개스킷을포함하고, 상기 EGR 밸브는전자제어유닛의제어에기초하여정역회전운동하는모터, 상기모터의회전운동을전달받아승강동작하는밸브로드및 상기밸브로드의하단에설치되어상기제 2배출가스유로를개폐하는밸브시트플레이트를포함하며, 상기밸브로드의일부분은상기모터의내부에나사결합되는구성을마련한다. 상기와같은 EGR 밸브조립체를이용하는것에의해, 본발명은모터의회전운동을이용해직접밸브로드를승강동작시켜 EGR 밸브의응답성을향상시키고, 밸브결합부재와하우징을통해냉각수를순환시켜재순환되는배기가스의온도가과도하게상승하는것을방지한다.

Abstract translation: EGR阀组件包括废气流入EGR阀组件的下部的入口端口，废气通过其排放的废气端口以及形成在废气端口与出口端口之间的第一废气流动通道和第二废气流动通道。 EGR阀，其与外壳连接并在第一和第二排气流动路径之间打开和关闭;以及垫圈，其设置在外壳和EGR阀之间， 阀座板安装在阀杆的下端，用于打开和关闭第二排气通道，其中阀杆的一部分连接到阀座板， 并在电机内部提供螺钉连接。 根据本发明的EGR阀组件能够通过利用马达的旋转运动直接移动阀杆并且使冷却水通过阀接合构件和壳体循环来提高EGR阀的响应性， 从而防止气体温度过度升高。
