BY-PASS VALVE HAVING EGR VALVE

摘要

PURPOSE: An EGR(Exhaust Gas Recirculation) valve integrated bypass valve is provided to efficiently reduce the nitric oxide by cooling exhaustion gas flowing into a EGR cooler. CONSTITUTION: An EGR valve integrated bypass valve includes an inhalation hole, a first exhaust pipe, a second exhaust pipe, a gas transfer furnace, an EGR valve mounting unit, an EGR valve(120), and a flap. The inhalation hole is formed in one side of a valve housing(110). The first exhaust pipe is formed in the other side of the valve housing and is connected to a cooling channel of the EGR cooler. The second exhaust pipe is contiguous to the first exhaust pipe and is connected to the bypass channel of the EGR cooler. The gas transfer furnace is formed inside the valve housing. The EGR valve is combined through the EGR valve mounting unit. A part of the EGR valve is located in the inhalation hole of the gas transfer furnace and inhales or secludes the exhaust gas. The flap is installed in a branch point and selectively switches the first and the second exhaust pipe.
