A turbomachine is described comprising a housing (2) at least two blade wheels (3 4) rotatably accommodated by the housing (2) at least two rotatably arranged blades (6) which are evenly distributed along a circle of the at least two blade wheels (3 4) and mounted with an axle parallel to the axis of the corresponding blade wheel. According to the invention each blade axle (6) is connected to an adjusting element (22 23) which can be displaced relative to the shaft of the second blade wheel (4) via a four bar link which lies in a plane perpendicular to the blade axle and consists mainly of a square arm that is fixed to the axle of the blades wherein a square arm is articulated to the bottom of the blade wheel whereas the other end is connected to the end of the first square arm via a connecting axle wherein the arm articulated to the bottom of the blade wheel is articulated to a sliding block in a positively driven manner said sliding block being displaceable in a guide which is fixed to the adjusting element wherein the sliding block guide system combined with the rotation of the blade wheel permits a control of the corresponding blade with a harmonic profile according to a curvature which can be altered similar to a sinusoidal line with an axis that coincides with the pitch circle of the blade wheel. |
