Description
Steuerung für einseitig arbeitende Preßluftmotoren. Es ist bei einseitig arbeitenden Preßluftmotoren bekannt, die Steuerung durch einen kraftschlüssig gesteuerten Schieber in Verbindung mit einem vom Kolben angeschlagenen, also in das Zylinderinnere einragenden Hilfsschieber vorzunehmen. Dabei wird die Hublänge dadurch bestimmt, daß eine Auspufföffnung, die in der Zylinderwandung angeordnet ist, vom Kolben überschliffen wird. Die Hublänge liegt also insoweit fest, als sie mit der Lage dieser Öffnung bestimmt ist.Control for single-sided compressed air motors. It's one-sided at working compressed air motors known, the control by a force-fit controlled Slide in connection with a struck by the piston, i.e. in the inside of the cylinder make protruding auxiliary slide. The stroke length is determined by that an exhaust port, which is arranged in the cylinder wall, is ground by the piston will. The stroke length is therefore fixed to the extent that than they are with the location this opening is intended.
Durch die Erfindung soll die Hublänge für jedes Bedürfnis eingestellt werden können. Zu diesem Zweck ist ein zweites Hilfsventä dem kraftschlüssig gesteuerten Hauptventil zugeordnet, welches von einem Anschlag, der von der Kolbenstange getragen wird, bedient wird. Der Anschlag kann, auf der Kolbenstange verschoben und in jeder Lage festgestellt werden. Trifft er gegen das Hilfsventil, so steuert er das Hauptventil um, derart, daß der Auspuff frei wird. Damit ist dann auch die Umsteuerung des Arbeitskolbens bestimmt.The invention aims to set the stroke length for every need can be. For this purpose, a second auxiliary valve is the non-positively controlled one Associated main valve, which is carried by a stop carried by the piston rod is served. The stop can be moved on the piston rod and in each Location to be determined. If it hits the auxiliary valve, it controls the main valve um, in such a way that the exhaust becomes free. This then also reverses the working piston certainly.
In. der Zeichnung ist die Erfindung schematisch dargestellt.In. the invention is shown schematically in the drawing.
Im Zylinder a wird Kolben b geführt. Durch den Kolbenschieber b wird die Druckluft gesteuert, indem durch diesen Schieb.err je nach seiner Stellung bald der Durchgang des- Treibmittels durch den Kanal d freigegeben und der Auspuff e abgeschlossen ist, wie es die gezeichnete Stellung erkennen, läßt, bald aber umgekehrt die Zuströmung nach =Übergang in die Linksstellung verschlossen und der Auspuff geöffnet wird. Die Bewegung des Kolbenschiebers c geschieht durch die beiden Hilfsventile f, il, von denen das Ventil f vom Kolben b und f 1 vom Anschlag g angeschlagen wird. Die Kammer k steht ständig unter Preßluftdruck, da sie durch den Kanal i mit dem Zuführungskanal d in Verbindung steht. Sie steht ferner in Verbindung mit der Kammer hl durch den Kanal k.Piston b is guided in cylinder a. The compressed air is controlled by the piston valve b by the passage of the propellant through the channel d and the exhaust e is closed, as can be seen in the position shown, soon reversed, depending on its position through this Schieb.err Inflow to = transition to the left position is closed and the exhaust is opened. The movement of the piston valve c takes place through the two auxiliary valves f, il, of which the valve f is struck by the piston b and f 1 by the stop g . The chamber k is constantly under compressed air pressure, since it is in communication with the supply channel d through the channel i. It is also in communication with the chamber hl through the channel k.
In der gezeichneten Darstellung befindet sich der Kolben b noch in seiner Bewegung nach links. Trifft nun der Anschlag g gegen das Ventil/-, so wird der Kanal l offengestellt und der Kolbenschieber c geht nach links. Damit öffnet sich der Auspuff e, so daß der Hub sein Ende erreicht hät. Nunmehr bewegt sich der Kolben b in bekannter Weise unter der Gewichtswirkung- der Rinne oder unter einem fremden Gewichte zurück, bis er gegen f anschlägt. Dadurch wird der Kanal m offengestellt, und es tritt wiederum die Umsteuerung ein, die den Ventilkolben c in die gezeichnete Stellung nach rechts zurückführt. Die Hublänge kann durch entsprechende Verschiebung des Anschlages g auf der Kolbenstange auf jedes beliebige Maß eingestellt werden.In the illustration shown, piston b is still moving to the left. If the stop g hits the valve / -, the channel l is opened and the piston valve c moves to the left. This opens the exhaust e so that the stroke has reached its end. The piston b now moves back in a known manner under the effect of the weight of the groove or under an external weight until it strikes against f. As a result, the channel m is opened, and the reversal occurs again, which returns the valve piston c to the position shown to the right. The stroke length can be adjusted to any dimension by moving the stop g on the piston rod accordingly.
