August 17, 2011
The present invention relates to an exhaust gas recirculation valve in a vehicle in which two valves are controlled individually by using one driving source and which enables secure operation of a vehicle even in a case the driving source is out of order. The exhaust gas recirculation EGR valve in a vehicle includes a driving unit (100) having a driving motor (102) for rotating a motor shaft (101), an interlocking unit for receiving rotation force from the motor shaft (101), a rod portion (300) arranged perpendicular to the interlocking unit for moving upon reception of the rotation force from the interlocking unit, a valve unit (400) provided to an end portion of the rod portion (300) for controlling a flow rate of the exhaust gas, and a valve housing (500) coupled to the driving unit as one unit, having an EGR port (532) and a bypass port (534), wherein the interlocking unit includes a valve return member (600) for rotating the motor shaft (101) forcibly to make the valve unit (400) to move to an initial position.
