The controllable vane compressor according to the invention has the advantages that pressure loading of the inner circular-arc-shaped vane surfaces (35) is produced by the selected minimal spring pressure, which acts even at standstill, and a surface-related dynamic pressure, which is built up on the relatively large inside vane surfaces (29) directly at start-up in the lowest rotational speed range, and a sufficient internal pressure on the sealing vane elements (22) against the inner circumferential housing wall (23) is produced, said internal pressure further increasing proportionally when the rotational speed increases. Tipping or tilting is completely prevented by the joint-like fastening of the vane elements (22). During the construction of the vane compressor, radially inward leakage is prevented by slide ring seals (32) inserted on both sides on the rotor (15). A controllable vane compressor has vanes (22) which are actually curved in a circular arc shape and which, at the rear end as viewed in the direction of rotation, are positioned in the manner of joints with the circular pin-like shape of the vanes as joints in the bores distributed evenly on the rotor (15). |
