Abstract

PURPOSE: To provide stabilized driving of an impeller by automatically making a labyrinth bush slide to regulate the labyrinth gap by a control device actuated by the suction flow rate and the exhaust pressure to regulate the by-pass flow rate.
CONSTITUTION: A flow rate indicating regulator 6 calculates the required by-pass flow rate (Q2-Q1) using a pressure differential signal given by an orifice 2 and an exhaust pressure signal given by a pressure signal generator 4. The result of the calculation is sent to a regulator 12 which calculates the labyrinth gas δB required for allowing the flow of the calculated by-pass flow rate. A position detecting probe 13 send a labyrinth gap signal to the regulator 12 where the measured labyrinth gap signal is compared with the calculated gas δB, then the opening of a pressure control valve 19 is adjusted to shift and fix a labyrinth bush 11 at a position where the labyrinth gap coincides with the calculated gap δB. Thus stabilized driving of the impeller 10 is provided as the by-pass flow rate is continuously adjusted to (Q2-Q1).
