Claims (7)
daß ein zylindrisches Rohrstück vorgesehen ist, das an seiner Innenwandung mit einem mit einem Innengewinde versehenen Abschnitt versehen ist, der mit einem mit einem Außengewinde versehenen Abschnitt der Schwenkwelle in Eingriff ist,
daß das Rohrstück ein in einem in dem Gehäuse ausgebildeten Zylinderraum axial verschieblicher, aber undrehbar gehaltener Ringkolben ist,
daß die Steigung des Gewindes so groß ist, daß der Ringkolben durch seine Axialverschiebung der Schwenkwelle das erforderliche Drehmoment zu erteilen vermag, und
daß der Verschiebeweg des Ringkolbens zwischen den beiden ringförmigen Zylinderkammern, die im Wechsel mit Hydrauliköl beaufschlagbare Hoch- und Niederdruckkammern sind, dem gewünschten Schwenkwinkel der beiden Schafen entspricht.5. swivel motor, preferably for a reversible fork according to claims 1 to 4, consisting of a tubular housing in which a rotatable by hydraulic forces pivot shaft is mounted, characterized in that
that a cylindrical tube piece is provided, which is provided on its inner wall with a section provided with an internal thread, which engages with a section of the pivot shaft provided with an external thread,
that the tube piece is an annular piston which is axially displaceable but rotatably held in a cylinder space formed in the housing,
that the pitch of the thread is so large that the annular piston can give the required torque by its axial displacement of the swivel shaft, and
that the displacement of the annular piston between the two annular cylinder chambers, which are alternately pressurized with hydraulic oil high and low pressure chambers, corresponds to the desired swivel angle of the two sheep.
