ABSTRACT:
A valve block for glassware forming machines is rendered faster and more accurate by substituting, for the pilot air valve system, a plurality of solenoids directly coupled with the cartridge valves, the coupling between said solenoids and said valves comprising a lost motion mechanical memory which, on reception of one pulse by the solenoid, pushes the cartridge valve and forces it to remain open, until reception of the next pulse by said solenoid, when it releases the cartridge valve to be closed; and a compensating spring, which is stronger than the force necessary to open said valves but weaker than the maximum force exerted by said solenoid, between said lost motion mechanical memory and said cartridge valve.
