Technical Examples

The invention is a pressure reducing valve for reducing the pressure supplied to a head tooling hydraulic positioning valve and a controller for bypassing the pressure reducing valve in a blow-molding machine. A pressure-reducing valve and electrical controller are used to regulate the pressure of a cylinder that controls the position of a head tooling pin and die assembly in a blow-molding machine. The invention reduces pressure during all time intervals except during a "parison formation" interval of the cycle. The invention is also a process for regulating the pressure of a cylinder that controls the position of a head tooling pin and die assembly in a blow-molding machine and for bypassing the pressure reducing valve in a blow-molding machine.
