    摘要: An object is to provide an exhaust-gas purification device that is capable of uniformly mixing exhaust gas and a reduction agent together without being affected by the routing of an exhaust pipe of an internal combustion engine. An exhaust-gas purification device (1) includes an urea water injection nozzle (2) that is provided inside an exhaust pipe (14) and a catalyst reactor (12) that is provided on a downstream side of the urea water injection nozzle, and is configured to inject urea water from the urea water injection nozzle (2) into exhaust gas of an engine (18) and to reduce nitrogen oxide in the exhaust gas by a NOx catalyst (13) contained in the catalyst reactor (12), where the urea water injection nozzle is disposed in such a way as to inject the urea water from the axial center of the exhaust pipe toward the downstream side of the flow direction of the exhaust gas, and a mixer (11) is connected to an upstream end of the catalyst reactor, the mixer having a plurality of plate members (11b) radially disposed around the axial center of the exhaust pipe, the plate members each being formed in such a way that angles of plate surfaces (A, B) of the plate member to the flow direction of the exhaust gas are different values on the upstream side and the downstream side.

    摘要: In a pressure fluid control valve device, the fluid exhausted from an internal combustion engine flows through a pair of paths selectively or simultaneously.Each of the paths is opened and closed by a butterfly valve (12,13) fixed to a valve shaft. A coupling for connecting the valve shafts across the paths comprises a slitting recess (9a) and a projection (10a) provided at the opposing ends of the valve shafts respectively. The direction of the surface of the recess and the projection is set to within 30 degrees with respect to the direction of the surface of the valve disc fixed to the valve shaft having the recess. Thus, the corner of the recess is not engaged with the bearing surface which is loaded, thereby making axial length for connecting the valve shafts to zero to manufacture the light and compact device.
