    • Disclosed is a bypass valve for vehicles, which provides effective control of exhaust gas, permits effective use of an internal space of the bypass valve, and guarantees good durability of flaps and a shaft. The bypass valve includes a valve-housing coupled to an outlet of an EGR cooler, a first intake port formed on one side of the valve-housing and connected to a cooling passage of the EGR cooler, a second intake port on the one side of the valve-housing and connected to a bypass passage of the EGR cooler, an exhaust port on the other side of the valve-housing, a first transfer channel in the valve-housing to connect the first intake port to the exhaust port, a second transfer channel in the valve-housing to connect the second intake port to the exhaust port, a first flap rotatably disposed in the first transfer channel, and a second flap rotatably disposed in the second transfer channel. The first and second flaps selectively open or close the first and second transfer channels to allow some of exhaust gas from an exhaust manifold to be directly recirculated to an intake manifold or to be recirculated thereto after being cooled.
    • 公开了一种用于车辆的旁通阀,其提供废气的有效控制,允许有效地使用旁通阀的内部空间,并且保证翼片和轴的良好的耐久性。 旁通阀包括联接到EGR冷却器的出口的阀壳体,形成在阀壳体的一侧并连接到EGR冷却器的冷却通道的第一进气口,在EGR壳体的一侧上的第二进气口 所述阀壳体连接到所述EGR冷却器的旁通通道,所述阀壳体的另一侧的排气口,所述阀壳体中的将所述第一进气口连接到所述排气口的第一输送通道, 将第二进气口连接到排气口,可转动地设置在第一传送通道中的第一挡板和可旋转地设置在第二传送通道中的第二挡板。 第一和第二翼片选择性地打开或关闭第一和第二输送通道,以允许来自排气歧管的一些排气直接再循环到进气歧管或在冷却之后再循环到进气歧管。

    • 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.
    • 提供一种耐久性优异的车辆用旁通阀,能够容易地制造简单的结构,能够使排气选择性地排出的翼片平稳地工作,并且不会造成长时间的错误操作或变形 - 使用。 旁通阀包括:形成在阀壳体的表面中的进气口; 形成在所述阀壳体的另一表面中并连接到EGR冷却器的冷却流道的第一排气口; 第二排气口,形成为与所述第一排气口相邻并且连接到所述EGR冷却器的旁通流动通道; 气体输送通道,形成在所述阀壳体中并且具有形成在所述中间的接合部分,以连接所述进气口和所述第一和第二排气口; 耦合到所述接合部分的开放侧的壳体盖; 其两端联接到阀壳体和壳体盖并且可旋转地设置在接合部分中的轴; 翼片,其联接到所述轴的中部,以便选择性地打开和关闭所述第一和第二排气口; 以及驱动机构,其设置在阀壳体的一侧,以使挡板摆动。
