ABSTRACT:
The drive shaft is formed with a longitudinally extending groove and the wall of a blind bore formed in the valve disc for receiving the shaft is formed with a projection which fits in the groove by a punching operation. The mating parts are readily made by conventional metal forming techniques and there is no need to pierce the disc.
