| description | A two-part wastegate valve member assembly 37, eg for a turbocharger or power turbine, comprises a valve member 35 and a support member 36 having an aperture 80. The valve member 35 comprises a central portion 82 extending through the aperture 80 and two integrally formed end portions 84, 86 disposed on opposite sides of the aperture 80. Each of the two end portions 84, 86 has dimensions such that the valve member 35 is held captive by the support member 36. A method for forming the two-part wastegate valve member assembly 37 comprises casting a single manufacturing intermediate 140, eg by investment casting, and processing the intermediate 140, eg by cutting, so as to form the two-part assembly 37. The second end portion 86 may be deformed, eg in a hydraulic press, to reduce the extent of movement of the valve member 35. Vibration may be used to deburr the assembly 37. |
