Abstract

Die Erfindung betrifft ein Verfahren zum Stellen der Geschwindigkeit einer mit einem gasförmigen Druckmedi­ um, insbesondere mit Druckluft betriebenen Antriebseinheit, dadurch gekennzeichnet, daß das gasförmige Druckmedium während eines Arbeitsvorganges zumindest zeitweise, vor­ zugsweise während des gesamten Arbeitsvorganges, pulsie­ rend in die Antriebseinheit eingespeist und/oder abgelassen wird. Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens, gekennzeichnet durch eine Antriebseinheit (1), die über eine Druckluftleitung (2) mit einem elektrisch betätigten Magnetventil (3) in Verbindung steht, das mit einem elektrischen Kabel (4) mit einer speicherprogrammierbaren Steuereinrichtung (5) verbunden ist. The invention relates to a method for making the Speed of one with a gaseous pressure medium um, in particular drive unit operated with compressed air, characterized in that the gaseous pressure medium at least temporarily during a work process preferably during the entire process, pulsie rend fed and / or discharged into the drive unit becomes. The invention further relates to a device for Carrying out the process, characterized by a Drive unit (1) with a compressed air line (2) an electrically operated solenoid valve (3) stands that with an electrical cable (4) with a Programmable logic controller (5) connected is.
