Abstract:
1. A rotary machine which comprises: a stator, a rotor with a plurality of channels wherein a plurality of axially movable displacers are located, a mechanism for setting an axial mutual position of the displacers, a working chamber bounded in axial direction by a first flank of the rotor and comprising a suction space and a pumping space connected correspondingly to an inlet port and an outlet port, a partition mounted on the stator opposite the first flank of the rotor, an axially movable regulating member mounted on the stator opposite the first flank of the rotor, an additional working chamber bounded in axial direction by a second flank of the rotor and including its own working suction space and pumping space, a partition and an axially movable regulating member both mounted on the stator opposite the second flank of the rotor, which regulating member is mounted so that its flank perpendicular to the rotor axis, is located opposite the perpendicular to the rotor axis flank of the partition which is mounted on the stator opposite the first flank of the rotor, wherein the partition mounted opposite the second flank of the rotor is mounted so that its flank perpendicular to the rotor axis is located opposite the perpendicular to the rotor axis flank of the regulating member mounted on the stator opposite the first flank of the rotor, wherein the regulating members are kinematically tied so that movement of one regulating member causes the other regulating member to move, wherein the working spaces of both the working chambers located in axial direction opposite one another are connected to each other by channels, and wherein the mechanism for setting an axial mutual position of the displacers is made so that it insures sliding contact of each regulating member with at least one displacer.
