Description
,Wird ein an einem Gerät angeschlossener Schlauch von einem aufgefärigteii'oder'ahi B<J4en liegenden zusammengerollten Stapel abgezogen, so wird er dabei axial verdreht, weil seine starre Befestigung sowohl an dem Gerät ad*jajicfe..an der Druckiaptstelle einen Ausgleich der Torsion durch Zurückdrehen nicht zuläßt. Der Verdrehungsgrad ist der Anzahl der von dem Stapel abgezogenen Schlau^M-| windungen direkt proportional. Wird nun ein di verdrehter Schlauch beim Verbringen des G'i die Arbeitsstelle durch Nachschleppen allniM. gestreckt, so ziehen sich die am Boden liegf * Windungen zu ständig kleiner werdenden Schleifet! zusammen, die, besonders bei dünnwandigen Schläuchen,, bis zum Einknicken des Schlauches führen können. . '■ " ' ' "''' ' If a hose connected to a device is pulled from a rolled-up stack lying on it, it is rotated axially because its rigid attachment to the device ad * jajicfe..at the pressure point compensates for the torsion by turning back does not allow. The degree of twist is the number of loops ^ M- | pulled from the stack turns directly proportional. Now a di twisted hose when moving the G'i the job by dragging allniM. stretched, so the * turns lying on the ground pull themselves into ever smaller loops! which, especially with thin-walled hoses, can lead to the hose kinking. . '■ "''"''''

Zweck der nachstehend beschriebenen Erfindung ist, die bisher nur auf umständliche und zeitraubende Art durch Drehen des ganzen Arbeitsgeräts zu beseitigenden Schlingen und Würgstellen an Schläuchen schon im Entstehen zu verhindern oder bei ungünstigen Schlauchlagen solche doch entstandene Stellen selbsttätig'zuTie'seitigen. r The purpose of the invention described below is to prevent the loops and choking points on hoses that had previously only arisen in a cumbersome and time-consuming manner by turning the entire work device, or to automatically end such places in the case of unfavorable hose positions. r
Die Kupplung, besteht aus vier Einzelteilen (Abb. 1). In dem ;?yljndri*eh*n Hohlkörper 1 bcr findet sich der leicht drehbare am äußeren Ende mit einer Schlauchtülle versehene Kolben 2. Den Abschluß des Hohlkörpers bildet der eingeschraubte, außen ebenfalls mit einer Schlauchtülle versehene" Abschlußkörper 3. Zur Abdichtung ist auf dem inneren Boden des Hohlkörpers der Gummidichtungsring 4 eingebracht. .,....'The coupling consists of four individual parts (Fig. 1). In the;?

Die Wirkungsweise der Vorrichtung ist folgende. Sowie die Schlauchleitung unter Druck gesetzt wird, verschiebt sich infolge des^ entstehenden Innen-. drucks der Kolben 2 in Richtung nach außen und preßt sich mit seiner der Druckluft abgekehrten unteren Fläche an den Dichtungsring 4 an. Um ein vollkommenes Dichthalten der Kupplung bei gleichzeitiger leichter Drehbarkeit zu erzielen, ist an der unteren Kolbenfläche eine im Querschnitt schneidenförmige Dichtungsleiste ausgedreht, die sich in den Dichtungsring 4 eindrückt, jedoch wegen ihrer sehrThe operation of the device is as follows. As soon as the hose line is pressurized, shifts as a result of the interior. pressure of the piston 2 in the outward direction and presses itself away from the compressed air with its lower surface to the sealing ring 4. In order to achieve a perfectly tight holding of the coupling while at the same time being easy to rotate, the Lower piston surface turned a cross-sectional cutting edge-shaped sealing strip, which is in the Sealing ring 4 pushes in, but because of their very
