Definitions

  • the present invention pertains to the Machine Building industry and it can be used for directing the flow of a medium (water, air) in any direction, and, also, for giving rise to rotative motion of rotatable members in any kind of devices by placing the working member into the moving flow.

  • Such devices are described in a number of patents (DE-PS589452, EPA-0283439, EP-B-O 614028), and in an international application PCT/CH 00341 which has been regarded as most relevant to the present invention.
  • the device which is the most relevant to the present invention operates in the following manner: rotative motion of the rotary shaft by means of the rotary lever connected rigidly to the running lever by means of the rotation bearing ensures that the running lever performs complex motion, i.e. rotates both about its own axis and along the conical trajectory.
  • rotation of the rotary shaft by a certain angle precisely corresponds to the rotation angle of the running lever about its own axis, yet its position along the conical trajectory.
  • Changing of the rotation angle of the rotary shaft causes rotation of the running lever about its own rotation axis.
  • rotation angle of the running lever about its own axis is twice less than the rotation angle of the rotary shaft about its own axis during the whole process of operation, i.e. performing rotation by 180° angle about its own axis the rotary shaft causes rotation of the rotary lever by 90° angle, and, correspondingly, rotating of the rotary shaft by 360° angle the rotary lever turns by 180° angle, and so forth.
  • connection between the rotary shaft and the running lever is made fixed and rigid.
  • Such connection is possible by an angle existing between the rotation bearing rotation axis and the rotation axis of the running lever.
  • the value of the angle defines conical outline of the lever rotation trajectory.
  • the running lever becomes capable of turning freely about its own rotation axis not regarding the dynamic conditions of the rotary shaft and rotary lever, i.e. regardless they are rotating or not. This is why the internal aperture of the rotation bearing turns along with the axis inserted therein and the cinematical connection is upset which causes blocking of the device and breaking of it during its operation.

  • Another objective of the present invention is to provide proportionality of the angular accelerations of the running lever with respect to the axis of the conical trajectory and, also, with respect to its own rotation axis and that of the rotary shaft.
  • Yet another objective of the present invention is to provide continuous change in direction of the total vector of forces developed by the running lever directly in the process of operation.
  • another objective of the present invention is to provide variability of the inclination angle of the running lever rotation axis with respect to the rotation axis of the rotary shaft (so called adjustable cone), and, also, to provide capability of increasing the number of running levers for a single rotary shaft in order to carry the pulsed mode of the running lever operation cycle,
