BYPASS VALVE HAVING EGR VALVE

摘要

A bypass valve having an EGR valve in which the bypass valve and the EGR valve are assembled into a module is provided. The bypass valve having an EGR valve includes: an intake port formed in a side surface of a valve housing; a first exhaust port formed in another side surface of the valve housing and connected to a cooling flow channel of an EGR cooler; a second exhaust port formed adjacent to the first exhaust port and connected to a bypass flow channel of the EGR cooler; a gas transfer channel formed in the valve housing and having a junction section formed in the middle thereof so as to connect the intake port to the first and second exhaust ports; an EGR valve coupling section formed in the top surface of the valve housing close to the intake port; the EGR valve coupled to the EGR valve coupling section and partially located at a position of the gas transfer channel close to the intake port so as to pass or intercept exhaust gas; and a flap swingably disposed in the junction section so as to selectively open and close the first and second exhaust ports. Since the bypass valve and the EGR valve are assembled into a module, it is advantageous for guaranteeing a space of an engine room at the time of designing a vehicle engine. In addition, the components for connecting the bypass valve and the EGR valve are not necessary, thereby reducing the cost.
