A variable nozzle turbocharger has a ring of vanes mounted within the annular passageway through which exhaust gases flow from a volute to the turbine rotor. The vanes can pivot on pins mounted in axial bores in a nozzle ring which defines one side of the passageway and is secured to the housing by dowels or bolts. The free ends of the vane pins are secured to respective vane arms which have outer ends which can rock in slots on the radially inner surface of a unison ring . The unison ring is mounted on rollers on dowels located in relation to the housing and the nozzle ring and can be turned around the nozzle ring by an external crank mechanism to pivot all the vanes together to vary the angle at which the exhaust gases are directed at the turbine rotor. The dowel and roller guides maintain the unison ring concentric with the nozzle ring which is itself concentrically located in relation to the housing.


Tonglint can design, process and produce nozzle rings per clients' drawings or samples. 


For clients in need of nozzle rings, it is strongly recommended to provide us the model and assembly no. of products. If you have some special requirements for a certain model, please specify your requests and offer the technical parameters.
