  • Patent number: 4792068
    Abstract: A nozzle with at least one opening that can be closed off, and especially a nozzle for packaging machines, including those that handle liquid products, with a valve body in the form of a piston that moves back and forth between a retracted position wherein it leaves the opening free and an advanced position wherein it completely closes off the opening. The object is to provide a nozzle with highly effective product-trimming action and continued piston operation even during the sterilization process. A guide for the piston has at least two positioning surfaces that operate in conjunction with two essentially opposite surfaces on the piston and precisely position it in the nozzle opening. The piston is axially divided or slit. Tensioning components force the halves of the piston apart and tight against the walls of the nozzle opening.
