FIELD: engines and pumps.
SUBSTANCE: turbomachine comprises at least one screw with cowling with variable-pitch blades. These blades are retained by cylindrical plates fitted on spinning pins (B) fitted in radial grooves of circular rotor element and interconnected by their radially inner ends with adjusting ring. Said ring spins about turbomachine shaft (A) and reciprocates there along to drive the plates about their axes. Said adjusting ring is centred and driven about turbomachine axis at means that cannot spin bur are reciprocated along said axis by power cylinder retained by turbomachine stator. Said adjusting ring centring and guiding means comprise circular guide that features U-like cross-section. Aid guide comprises two lateral walls to confine circular flute extending outward. Adjusting ring is fitted in said flute. Bearings are arranged on both sides of adjusting ring between it and lateral walls.
EFFECT: simplified and efficient design.
