PURPOSE: A device for integrating a turbo charger pressure control valve and an exhaust gas recirculation valve is provided to reduce a space occupied by two valves and to save a raw cost by unifying a wiring and a connector. CONSTITUTION: A device for integrating a turbo charger pressure control valve and an exhaust gas recirculation valve comprises a guiding pipe(40), a branch portion(50) and an operating portion(70). The guiding pipe is branched from an exhaust pipe(24) between an exhaust manifold(20) of an engine(10) and a turbo charger(22). The branch portion is formed in the guiding pipe to connect the guiding pipe to an intake manifold(30) and an exhaust pipe(24). The operating portion is controlled by an ECU(electronic control unit)(60) in the branch portion to selectively change the direction of exhaust gas. Thus, a pressure control valve and an exhaust gas recirculation valve are integrated together, then a space occupied by two valves is remarkably reduced and the number of components is decreased. Furthermore, a wiring and a connector are unified to save a raw cost and to enhance maintenance efficiency.
