Piston assembly having a fusible core to form a cooling channel and a method for the manufacture thereof |
摘要 |
A piston is formed with a cooling channel in its crown by dissolving a fusible core cast into the crown. The fusible core is supported prior to casting by a strut which is itself supported on a plurality of cores which help to find the piston cavity. The plurality of cores are configured so as to be removable from the strut, after casting, in a downward direction. The fusible core is dissolved by introducing a dissolving liquid to the fusible core via inlet or outlet passages cut between the cavity and the fusible core.
