Definitions

  • the invention relates to a rotary piston machine with stroke and slip engagement with a piston arranged centrally within a housing shell, which by means of sealing elements - radially movable vanes or rollers - is in sealing engagement with the inner surface of the housing shell, the generatrix of which consists of working and sealing bends.
  • this arc and the hypertrochoid representing the main part of the stroke curve were connected by an arc, which mostly belongs to the circumference of a circle, the center of which is of course different from the center of the guideline of the rotor.
  • a plane curve is of the symmetry order s with reference to a point O if the revolution with the amplitude 2 ⁇ / s around point O is the smallest revolution through which the curve returns to itself.
  • This revolution of the smallest amplitude is the revolution that brings a point A of the curve, at which the polar radius is minimal, to congruence with point B of the curve, at which the polar radius is again minimal and which one encounters when one moves away from point A moving in the direction of rotation on the curve.
  • the generator (stroke curve) is a closed hypertrochoid, the symmetry order S H of which differs from the symmetry order S s of the stroke curve and is necessarily expressed by a rational number, which, however, must not be an integer, and by is given, where one puts.
  • Each hypertrochoid is contained in a circular ring, the outer periphery of which the hypertrochoid circumscribes is necessarily real and has a radius R a , which is defined as follows: and the periphery inscribed in the hypertrochoid has a radius R j , the module
  • the invention only considers those hypertrochoids for which the inner periphery is real. It is clear that the cylindrical hypertrochoid surface, the generator of which is a hypertrochoid, permits a cylindrical nucleus, the guideline of which is the periphery inscribed in the hypertrochoid. These hypertrochoids are called "nuclear hypertrochoids".
  • a shortened hypertrochoid is necessarily selected by numerically evaluating the complex number Z for all possible values of the parameter K between zero and K * .
  • the hypertrochoids used in the invention can be summarized as shortened nuclear hypertrochoids, the symmetry order S H of which is rational without being an integer.
  • the first working arc is any flap of the hypertrochoid; of course this flap is followed by a sealing sheet associated with the core of the hypertrochoid, the extreme end of which coincides with the beginning of the following flap sheet forming another working sheet, and so on, until one has returned to the beginning of the first flap sheet.
  • a stroke curve according to the present invention has a symmetry order S s with respect to its center point, without necessarily having the same symmetry with respect to any straight line emanating from this center point.
  • FIG. 1 and 2 show an example of the considerations set out above and FIG. 3 shows, as a simplified sectional drawing, a vane compressor according to the present invention.
  • the values of ßk are chosen so that the polar angle corresponding to the point of contact A of the first lobe with the core becomes 15 °.
  • the nuclear hypertrochoid according to FIG. 1 is completely defined in this way; it has twelve lobes and closes after five rounds.
  • FIG. 2 shows the generator (stroke curve) constructed in accordance with the invention and starting from the preceding nuclear hypertrochoid, the output being point A.
  • FIG. 3 shows a drawing of a compressor cut perpendicular to the axis, in which the stroke curve defined in FIG. 2 is used.
  • This compressor comprises a shaft 1, a rotor 2, the radius of which is R r , a housing jacket 3, which is delimited on the inside in the sectional drawing by the generatrix (stroke curve) 4.
  • the generator 4 has sealing arches 5 and 6. Inlet slots 7 and 8, and pressure valves 9 and 10 ensure the supply and discharge of the pressure medium.
  • An outer housing 14 surrounds the machine.
