    • An alternate valve assembly for a smoke re-combustion device of a engine includes a pair of alternate valves which are symmetrically installed at each inlet of filters connected with branches of an exhaust manifold. Each of the valves comprises a valve body which is supported to be rotatable by a shaft having a rectangular part and a protruded end, in bearings of a valve housing, with bushes interposed, an arm connecting the valve body with the shaft, an actuator being placed in the outside of the valve housing and being connected with the protruded end through a link, a collar being inserted in the periphery of the shaft, rings for maintaining airtightness being inserted in peripheries of the shaft and the protruded end and being pressed elastically by springs toward the inner ends of the bushes, a pair of retainer rings being inserted in the inside of the bearing which supports the protruded end, a packing being positioned between the retainer rings, a ring-shaped valve seat being inserted in and being supported by an annular groove having a jaw which is formed in the inner periphery of the inlet of the valve housing, and a cushion being fixed to the outside of the ring-shaped valve seat.
