A turbomachine, comprising a housing, at least two blade wheels rotatably accommodated by the housing, at least two rotatably arranged blades, which are evenly distributed along a circle of the at least two blade wheels and mounted with an axle parallel to the axis of the corresponding blade wheel.
A turbomachine, comprising a housing, at least two blade wheels rotatably accommodated by the housing, at least two rotatably arranged blades, which are evenly distributed along a circle of the at least two blade wheels and mounted with an axle parallel to the axis of the corresponding blade wheel. According to the invention, each blade axle is connected to an adjusting element, which can be displaced relative to the shaft of the second blade wheel 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.

1. A fluid dynamic machine with at least one impeller, comprising a body, the at least one impeller including a first impeller and a second impeller rotatably housed by the body, at least two blades rotatably arranged, uniformly distributed along a circumference of the at least one impeller and supported with a parallel axis to an axis of the at least one impeller, a shaft of the first impeller being connected to a first motion transmission means and a second impeller being connected to a second motion transmission means on a bottom of the second impeller, and the bottom of the second impeller is concentric with a bottom of the shaft of the first impeller, the first motion transmission means of the first impeller and the second motion transmission means of the second impeller are connected in a common drive shaft, wherein each blade axis is connected with an element that is capable of being moved with respect to a shaft of the second impeller through a serially articulated connector that is located in a plane perpendicular to the axis of the blade and that comprises a first arm of the connector integral with the axis of the blades, a second arm of the connector being pivoted on the bottom of the second impeller, whereas another end of the second arm is connected to an end of the first arm through a connection axis, the second arm being hinged on the bottom of the at least one impeller and being articulated to a sliding block in an integral guide with a movement element, a block-guide system combined with a turning rotation leading to a control of the respective blade with harmonic motion according to a variable curve with an axis coinciding with a part of circumference of the second impeller. 2. The machine according to claim 1, wherein a coinciding motion of bearing collars of each respective impeller on which the block-guide pairs are mounted for the control of the articulations of the serially articulated connector, and the impeller blades are actuated by a system of leverages and rods, the geometry of the leverages and rods of constraints and joints leads to an angular synchrony between the bearing collars and the each respective impeller, but leaving the same bearing collar free to be moved at the same time in the radial directions with respect to a longitudinal axis envisaged on the orientation plane. 3. The machine according to claim 2, wherein the leverage and rods system consists of the connector both for the blade of an internal impeller as the first impeller and for an external impeller as the second impeller, one of the ends of the first arm being articulated to each blade axis, another end of the first arm being articulated to one of two ends of a connection rod, the connection rod's other end is articulated to one of the ends of a lever articulated in a pivoted point to the bottom of the respective internal or external impeller, the lever being rocking-lever articulated to a sliding block in a guide integral with a ring or collar rotating on the bearing collars. 4. The machine according to claim 1 wherein the movement element comprises a supported and articulated carrier, being equipped with a spherical surface housed in a corresponding housing of the machine body; actuating means are provided to move the carrier with the carrier's pivot in a centre of rotation resting on the central axis of the machine, to eccentrically oscillate the carrier; on the carrier, a collar resting in a plane is arranged in a sliding manner in a direction at right angles to the shaft of the impeller; and the collar itself mounts a radial bearing respectively for each impeller with respect to the shaft of the impeller, from which a respective connector of the blade leverages are moved through a block-guide pairs; and the pivot of the oscillation of the carrier and the articulation of the actuating means, are inverted in the positioning, except for the decentralisation efficacy of the block-guide collar. 5. The machine according to claim 4 wherein the collar is moved with the block-guide system sliding in integral slots appropriately obtained in the geometry of the collar, and each block is articulated to the centre with a radially arranged shaft and parallel to the central axis of the machine, the machine is integral with a lever with an arch movement on a plane parallel to that of the impeller, which in turn is integral and moved by a shaft with a parallel axis to the central shaft, articulated to the corresponding housing of the machine structure and equipped with another arm moved by an actuator articulated to the machine structure. 6. The machine according to claim 1, wherein the machine further comprises a plurality of counter-rotating impellers synergized with the blades in the fluid; this combined with appropriate angular speeds of each impeller minimises the reactive, torsional and direction derivation effects, as well as making the thrust of any entity on the axis of rotation coincide. 7. The machine according to claim 1, wherein a system of actuators comprises a plurality of actuators, each actuator having a piston stem at a free end of which one of the ends of a connection arm is articulated, other end of the connection arm is articulated to a pivot rotatable in a flange integral with the body of the machine, one end of the pivot being articulated to one of the ends of the connection arm whose other end is articulated to a pivot housed in a housing integral with a carrier. 8. The machine according to claim 1, wherein one of the ends of a first elbow lever is articulated at the bottom of the first or second impeller, another end of the first elbow lever is articulated to a first rod, the first rod is articulated in turn articulated to a shackle which is also articulated to a lug integral with a ring, a first orientation lever also being articulated to the shackle articulated to the bottom of the first or second impeller, a second rod also being articulated to the shackle in turn also articulated to a second elbow lever to which one of the ends of a third rod is articulated, whose other end is articulated to a third elbow lever to which a fourth rod is articulated joined to a second shackle to which a second orientation lever is also articulated and it is articulated to a second lug integral with the ring and to which a fourth rod is articulated in turn articulated to a fourth elbow lever which is also articulated to the aforementioned first elbow lever.
