動についても非常に弱い欠点があった。(2) Conventional technology An outlet B of a direct exhaust path for directly exhausting exhaust gas such as engine exhaust gas entering from an inlet A and a waste heat recovery path provided with a waste heat recovery facility for effectively utilizing the waste heat of the exhaust gas. The three-way damper which can be switched to one of the two outlets having the outlet C and the outlet C is always in a completely closed state in order to avoid engine trouble and the like due to the completely closed state of the passage. From the functional requirements that must not exist,
When a two-way valve 21 is used for each of the two outlets B and C as shown in FIG. 6, there is an opportunity for the two outlets to be closed at the same time to be in a completely closed state, which is not preferable. As shown in FIG. 3, a three-way damper in which a valve plate 31 is rotatably attached to a valve shaft 32 provided at a corner between the outlets B and C is adopted. In the case of this three-way damper, the fluid that has entered from the inlet A switches the flow path to the outlet B or C by rotating the valve plate 31 by 90 degrees, and in addition to satisfying the above conditions,
Although it has the advantages of a simple structure and small size with little pressure loss, on the other hand, the operating tokule is very large, and because the installation location is around the engine, it is unavoidable that vibration is transmitted. Since one end is so-called cantilevered support supported by the valve shaft 32, the free end side of the valve plate 31 causes a chattering phenomenon that opens in small steps, and there is a drawback that it is very weak in vibration resistance such as lack of airtightness. It was

り位置決めされている。An inlet 2 is provided on one side of the damper case 1 and outlets 3 and 4 are provided on the other side. The valve shaft 5 is provided at the center of both side plates of the case 1.
Is rotatably supported. One end of a transmission arm 6 is fixed to predetermined portions on both sides of the valve shaft 5 in the case 1, and a long hole 7 elongated in the normal direction is formed at the center of the other end of the transmission arm 6. The pin portion 8 of the pin arm 11 is fitted into the elongated hole 7 of the transmission arm 6. Further, the pin portion 8 is slidably fitted along the groove path 10 of a linear guide rail 9 laid at equal angles with respect to the two outlets 3 and 4 on the back surface of both side plates of the case 1. An elongated hole 12 is opened in the arm portion of the pin arm 11, and the valve action 5 penetrates the elongated hole 12. A connecting rod 13 having a predetermined length which is perpendicular to the valve shaft 5 and extends in a direction substantially perpendicular to the valve shaft 5 can be attached to the square pin arm 11. 13
A valve body is provided at the tip of which is connected and fixed an end edge portion of an arc-shaped valve plate 14 having a radius of curvature as a distance between the valve shaft 5 and the outlets 3, 4. A weight 15 for balancing with the valve body is attached to an arm portion extending in the direction opposite to the valve mounting direction of the pin arm 11, and the weight 15 moves along the long hole 12 with respect to the valve shaft 5. The pin arm 11 which can be mounted is positioned by a ring 16 which is fixed to the valve shaft 5 inside the pin arm 11.

する。Since the present invention is configured as described above, first, the valve shaft 5 is at the position indicated by the solid line in the drawing, that is, the valve plate of the valve body.
When 14 rotates in the direction of the outlet 4 from the position where the outlet 3 is closed, the transmission arm 6 fixed to the valve shaft 5 integrally rotates in the same direction, and the rotation of the transmission arm 6 causes the transmission arm 6 to rotate. The pin portion 8 of the pin arm 11 into which the long hole 7 of 6 is fitted is provided with two outlets 3, 4 on the back surface of both side plates of the case 1.
Groove of straight guide rail 9 laid at an equal angle to
Sliding along 10. Accordingly, as the valve shaft 5 moves from the closed one outlet 3 to the intermediate position in the direction of the other outlet 4, the pin arm 11 immediate valve plate as shown in FIG.
14 is gradually pulled inward, that is, toward the valve shaft 5 side by the maximum movement width a. Then, when passing through the intermediate position, this time, conversely, the valve plate 14 is gradually pushed outward in response to the movement in the direction of the outlet 4 and finally rotated to reach the position of the outlet 4, and the valve plate 14 is moved to the outlet. 4 is pressed so that the valve is closed from the inside.

し、耐振動に優れた効果を発揮させることもできる。Therefore, when switching the flow path by moving the valve body from one outlet where the valve plate is closed to the other outlet, the valve body gradually reduces the radius of gyration of the valve plate, and the inside of the sealing surface When it reaches the position where the other outlet is closed, it moves in the original direction, and the force pressing against the sealing surface of the outlet acts to completely secure the shutoff. Further, by attaching a balance weight to balance with the valve element, the operation is smoothed, and it is possible to exert an excellent effect of vibration resistance.

The path mechanism makes it possible to minimize the amount of leak, has excellent airtightness and vibration resistance, and has many excellent effects such as simple structure and small size with little pressure loss and small operating torque. It is a thing.
