Abstract

The invention relates to a control means for actuating the valves for supplying pressurized blowing fluid and working fluid to the blow mold stations of the blow wheel of a blow mold machine. The blow wheel comprises a center-free wheel ring of which the outer periphery is rotatably supported on a base. Facing the inner periphery of the wheel ring there is a stationary rail on which carriages are adjustably mounted. The carriages accommodate cams for actuating the plungers of the valves mounted on the wheel ring through a yoke which provides a self-holding action. Thus, adjusting of proper valve operation is facilitated while the operation of the blow molding machine is continued.
