Abstract:

A bypass valve for a vehicle with excellent durability is provided, which can be easily manufactured with a simple structure, which can allow a flap for selectively discharging exhaust gas to smoothly work, and which does not cause an erroneous operation or a deformation in a long-term use. The bypass valve includes: an intake port formed in a surface of a valve housing; a first exhaust port formed in another surface of the valve housing and connected to a cooling flow channel of an EGR cooler; a second exhaust port formed to be 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 so as to connect the intake port and the first and second exhaust ports; a housing cover coupled to an opened side of the junction section; a shaft of which both ends are coupled to the valve housing and the housing cover and which is rotatably disposed in the junction section; a flap coupled to the middle of the shaft so as to selectively open and close the first and second exhaust ports; and a driving mechanism disposed on one side of the valve housing so as to cause the flap to swing.
