Abstract (en)

The compressor has a suction area that is sealed to an actuator (50) of a prerotation-guiding device, where the sealing takes place by an dip tube (54) that is movable tangential to an adjusting ring (30) of the guiding device. The adjusting ring adjusts a guiding blade (20) of the guiding device, where the actuator drives the adjusting ring and is designed as a stepper motor. A threaded spindle (52) engages in a spindle groove that is secured to the element. The adjusting ring is driven by a sliding pin (41) having milled grooves that are arranged in parallel.

Abstract (de)

Die Gewindespindel (52) greift in eine Spindelmutter (53) ein, welche an einem translatorisch verschiebbaren Element (54) befestigt ist. Durch Drehen der Spindel wird das Element in die gewünschte Position geschoben. Der Antrieb des Verstellrings (30) erfolgt über einen Gleitstift (41) mit parallel angeordneten Anfräsungen welcher drehbar in den beiden Laschen (33) des Nutringes gelagert wird.
