Patent ID: 7971578

Claim:
An EGR valve for a vehicle comprising: a valve housing connected to an exhaust line for discharging exhaust gas therethrough, having a flow line with an inside area divided for taking and re-circulating a portion of the exhaust gas to a suction manifold; a driving unit on one side of the valve housing, and a valve unit mounted in a flow line of the valve housing for receiving driving force from the driving unit directly to control flows of the exhaust gas flowing through the flow line at the same time, individually, wherein the valve unit includes: a plurality of valves configured to close or open a plurality of holes formed in the valve housing; and rotation shaft coupled to the driving unit and the plurality of valves, the rotation shaft including: a first rotation shaft coupled to the driving unit; a second rotation shaft coupled to the plurality of valves; and a coupling coupled to the first rotation shaft and the second rotation shaft for receiving rotation force through the first rotation shaft and for transmitting the rotation force to the second shaft, and for preventing heat from transmitting to the first rotation shaft from the second shaft.
