Description

Druckluftwerkzeug mit, zwei Kolben Die Erfindung bezieht sich auf Druckluftwerkzeuge mit zwei Kolben, und zwar einem Vollkolben und einem Hohlkolben, welche gleichen Querschnitt haben und wechselseitig arbeiten. Die Kolben gleiten in konzentrischen, luftdicht voneinander getrennten Zylindern und arbeiten abwechselnd auf einen Amboß.Pneumatic tool with two piston The invention relates to pneumatic tools having two pistons, namely a solid piston and a hollow piston which have the same cross-section and working alternately. The pistons slide in concentric, airtight cylinders and work alternately on an anvil.

Die Erfindung besteht darin, daß der Durchmesser des Ambosses gleich dem des Zvlinders für den Hohlkolben ist und die Trennwand beider Zylinder in den Amboß hineinragt.The invention consists in that the diameter of the anvil is the same that of the cylinder for the hollow piston and the dividing wall of both cylinders into the Anvil protrudes.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Das Druckluftwerkzeug besteht aus vier Teilen, und zwar aus dem äußeren Zylinder r, dem inneren Zylinder a, dem Werkzeuggriff 7 und dem Amboß 5. Die innere Zylinderwand z ragt in den Amboß 5 hinein und ist luftdicht eingepaßt. Am entgegengesetzten Ende ist die innere Zylinderwand 2 mittels Gewindes im Werkzeuggriff 7 luftdicht befestigt. Der Durchmesser des Ambosses 5 ist gleich dem des Zylinders für den Hohlkolben. Von den vier Werkzeugteilen werden die beiden luftdicht voneinander getrennten Zylinder gebildet. In diesen beiden Zylindern gleiten wechselseitig der Vollkolben 3 und der Hohlkolben 4., die beide gleichen Querschnitt haben.The drawing shows an exemplary embodiment of the subject matter of the invention shown. The pneumatic tool consists of four parts, namely the outer one Cylinder r, the inner cylinder a, the tool handle 7 and the anvil 5. The inner Cylinder wall z protrudes into anvil 5 and is fitted airtight. On the opposite At the end, the inner cylinder wall 2 is airtight by means of a thread in the tool handle 7 attached. The diameter of the anvil 5 is equal to that of the cylinder for the hollow piston. Of the four tool parts, the two cylinders are separated from each other in airtight manner educated. The full piston 3 and slide alternately in these two cylinders the hollow piston 4., both of which have the same cross-section.

Als Vorteil gegenüber bekannten Zweikolbenwerkzeugen mit ineinanderlaufenden Kolben ergibt sich durch die erfindungsgemäße Anordnung, daß für beide Kolben die ganze und damit gleiche Zylinderlänge als Arbeitshub ausgenutzt wird.As an advantage over known two-piston tools with one inside the other Piston results from the arrangement according to the invention that for both pistons whole and thus the same cylinder length is used as the working stroke.
