EQUIPMENT FOR FORMING CONTAINERS BY MEANS OF BLOW MOLDING COMPRISING AN IMPROVED DEVICE FOR CONTROLLING A VALVE FOR DISPENSING THE BLOW-MOLDING FLUID

摘要

The invention relates to forming equipment (10) provided with a dispensing valve (22), comprising: a piston (42) that divides a cylinder (40) into a first working chamber (44) and a second working chamber (46); and first controlled pressurization means for increasing the pressure of a fluid in the first working chamber (44) beyond an actuation pressure (Pa) that enables the piston (42) to be moved to the second switching position thereof, characterized in that the dispensing valve (22) comprises locking means that are controlled between a first locked state, in which the piston (42) is locked in the first switching position thereof, and a released state, in which the sliding of the piston (42)to the second switching position thereof is enabled.
