The present invention is directed to an exhaust gas recirculation valve (10) incorporating a DC motor (30) and a dual poppet valve assembly (22). A motor (30) is contained inside of the valve housing (36). The motor (30) has a rotatable motor shaft (56) with a first gear (58) connected to the end of the motor shaft (56). A second gear (60) is engageable to the first gear (58) and is configured to rotate in response to the movement of the first gear (58) and the motor shaft (58). The second gear (60) is also connected to a pin member (48) disposed through the top portion of a shaft (44) that has two poppet valves (38, 40) disposed on to the shaft (44). The two ends of the pin (48) member are slidably engageable to either an two slots (53, 55). When the second gear (60) rotates the shaft (44) rotates and moves upward or downward to cause the valve members (38, 40) to move between an open and closed position. |
