1. A compressor (1) for the transport of gases consisting of a vane wheel (2) fitted with vanes (3) to drive gas when the vane wheel (2) rotates, and of a cover (4) to delimit the working space and safeguard the moving parts of the compressor (1), which is equipped with at least one entry duct (5) for gas intake to the compressor (1) and at least one exhaust duct (6) to drive gas out of the compressor (1), further the compressor (1) is equipped with at least two compression barriers (8, 9) and a separator (10) to create the compression space where the external compression barrier (8) is arranged before the entry duct (6) in the direction of the vane wheel (2) rotation around at least a part of the trajectory of the outer rims of the vanes (3), the internal compression barrier (9) is arranged before the exhaust duct (6) in the direction of the vane wheel (2) rotation around at least a part of the trajectory of the inner rims of the vanes (3), and the separator (10) is arranged in the inlet of the exhaust duct (6), characterized in that the vane wheel (2) is formed by two circular bases (7) of the same diameter, the bases (7) of the vane wheel (2) are not axially aligned and their rotation axes (o) are parallel, the vanes (3) are attached between the bases (7) of the vane wheel (2) with the possibility of rotation around the axes (u) of their mounting allowing their tilting with the rotation of the vane wheel (2), the bases (7) are fitted with perpendicular pins (11) along the circumference on the near sides for fitting the vanes (3), and every vane (3) is on both sides equipped by holes for inserting the pin (11), where the pins (11) on both bases (7) are arranged in an alternating manner, where the internal compression barrier (9) and the separator (10) delimit the opening for the exit of the vanes (3) out of the compression space.

2. The compressor according to claim 1, characterized in that the pins (11) are shorter than a pitch of the bases (7).

3. The compressor according to claims 1 and 2, characterized in that the pins (11) are attached to bearings (12) which are integrated in the bases (7) of the vane wheel (2), or they are attached to the bases (7).

4. The compressor according to claims 1 to 3, characterized in that the pins (11) are attached to the bases (7) of the vane wheel (2) in a fixed manner and the vanes (3) include integrated bearings (12) for the pivotal mounting of the vanes (3) onto the pins (11), or the bearings (12) are attached to the vanes (3).

5. The compressor according to claim 1, characterized in that the internal compression barrier (9) is equipped with at least one compensating channel (13) to reduce pressure.
