Blow cylinder with fluid cushion

Novel blow cylinders use a retract fluid at a minimum pressure, located between a piston head and a wall of a cylinder body, to prevent the piston head from violently impacting the wall when the piston head is moved so that a blow needle engages a parison. The retract fluid at a minimum pressure is...

Zusammenfassung:	Novel blow cylinders use a retract fluid at a minimum pressure, located between a piston head and a wall of a cylinder body, to prevent the piston head from violently impacting the wall when the piston head is moved so that a blow needle engages a parison. The retract fluid at a minimum pressure is also used to move the piston head so that the blow needle disengages the parison.
