Claims (9)

1. Vorrichtung zum Abstrahlen der Innenflächen von Rohren (10), mit ei­ ner koaxial zum Rohr ausgerichteten, das Strahlmedium abgebenden Düse (12) und einem Ablenkkörper (16), der das Strahlmedium auf die Rohrwand lenkt, dadurch gekennzeichnet, daß der Ablenkkörper (16) mit dem grüßten Teil seiner Länge axial hinter der Mündung der Düse (12) liegt und allein oder gemeinsam mit der Düse durch das Rohr (10) bewegbar ist.1. Device for blasting the inner surfaces of pipes ( 10 ), with egg ner coaxially aligned to the pipe, the blasting medium emitting nozzle ( 12 ) and a deflector ( 16 ), which directs the blasting medium onto the pipe wall, characterized in that the deflector 16 ) lies with most of its length axially behind the mouth of the nozzle ( 12 ) and can be moved alone or together with the nozzle through the tube ( 10 ). 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Düse (12) als an das Rohrende ankuppelbarer Adapter zum Einleiten des Strahlme­ diums in das Rohr ausgebildet ist und daß der Ablenkkörper (16) relativ zur Düse durch das Rohr bewegbar ist.2. Apparatus according to claim 1, characterized in that the nozzle ( 12 ) is designed as a couplable to the tube end adapter for introducing the medium into the tube and that the deflector ( 16 ) is movable relative to the nozzle through the tube. 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß an dem Ab­ lenkkörper (16) ein Zugseil befestigt ist.3. Apparatus according to claim 2, characterized in that a traction cable is attached to the steering body ( 16 ). 4.
