ABSTRACT:
Centrifugal high-pressure machine comprising an impeller blade rotor positioned within a housing and a spiral chamber surrounding the housing and forming with the blade rotor a diffuser chamber. The machine is provided with an axially movable piston member which with an outer wall and an enclosure member constitutes a chamber of various volume. The chamber is arranged to be connected to the inlet of the machine and to the spiral chamber respectively. The piston member is positioned against a side wall of the blade rotor and has a lateral face congruent with that of the blade rotor. The axial movement of the piston member constitutes diffuser chambers of various geometry and volume.
