Definitions

  • This invention relates to a rotary machine which exploits inner cyclic variable volumes.
  • Such an engine as described in the preamble of claim 1 is shown in FR-A-2 235 268.
  • the rotary machine according to the invention is composed of:
  • the rotor is composed of N r sides (N r ⁇ 1) which have N e equal ends with equal surfaces E.
  • N e surfaces E with plane r are N e equal circles or radius r with centres P i which are points of respective axes Y I .
  • Points P run on a curve R N which characterises the rotary machine, as in the Wankel engine, the geometry of which is based on a curve R N , which is a trochoid curve.
  • Perimetral surfaces M or stator cavity U is the external envelope of the rotor surfaces E, which slide round touching surface M along N e equal lines.
  • the present invention has rotor points P, running on trajectories R N different from the above trajectories and described in claim 1.
  • the present invention can work as a pump, compressor, motor, engine, valve, distributor or hydraulic joint; it may burn fuel for heat and/or electricity as in magneto-hydrodynamic generators; it can also be used as a compressor and/or booster for thermic motors with inner reactive combustion.
  • Stator body 1 has an inner cavity with perimetral surface M.
  • Transmission shaft 14 has rotary axis Y c which intersects plane r orthogonally at point C.
  • the rotor touches contour M by interposed rings 10 of radius r.
  • Cylinders 4 and rings 10 have common axis Y I .
  • An non-extensible connection (bar 7) joins pivot/s 6 centered in points D with transmission shaft 14 ( Figures 2 and 3).
  • Rotor sides or pistons 5 have equal height, their flat bases are parallel to plane r and slip over the stator bases.
  • External surface 9 of each piston 5 corresponds to one rotating chamber V.
  • Integer N is modulus of curve R N .
  • Each chamber V is defined by piston wall 9, two surfaces E of rings 10, cylinder M, and two stator bases.
  • N r pistons 5 form one chamber Z of variable volume Z ( ⁇ ) .
  • Chamber Z is defined by N e surfaces 13 of pistons 5, N e surfaces E or rings 10 and the two stator bases; it pumps a fluid which enters and exits through holding valves (not shown in figures). Volumes V ( ⁇ ) and Z ( ⁇ ) are defined in any position of the rotor. The fluid in chamber Z cools and lubricates the machine and may feed a hydraulic accumulator (not shown in figures).
  • the rotor can be made by packing thin metal sheets together. It may also be an open prismatic structure, and composed of only one side without hinges, or composed of solid cylinders only. Chambers V and Z may be interconnected.
  • Figure 4 shows a schematic view of a coaxial cyclic volume machine composed of one rotating cyclic volume machine as a compressor, and one rotating cyclic volume machine as an engine, with one common transmission shaft 14 and one common stator base between them.
  • Operating fluid enters 3 and flows through the two transfer channels 23 bored in the common base, and is controlled by engine rotor P 1 P 2 P 3 p 4 .
  • the fluid enters the two opposite combustion chambers, where it is further compressed for combustion. Waste gases are discharged through channels 24 bored in the stator base of the engine side. Maximum fluid compression occurs in engine area 11, where ignition takes place and expansion of gases rotates the polygonal structure of the engine and the compressor.
  • cooling fluid enters the Z area of the compressor, passing through the Z area of the engine, and powers a hydraulic accumulator which is also a heat radiator (not shown).
  • Axes X 1 and X 2 form angle ⁇ on projection plane. Angle ⁇ is important for precompression of the engine when the axis of channel 23 is parallel to axis Y c .
  • Modulus N conditions the choice of the maximum number N r of rotor sides 1 ⁇ Nr ⁇ N which have number N e of equal cylindrical ends E; 2 ⁇ Ne ⁇ 2(Nr ⁇ 1).
  • Rotor points-P, of the present invention run along curve R N belonging to a new class of curves called ROTOID CURVES with the peculiar geometrical property called invariant length W.
  • Points Fi 1 to N, lie on curve L and distributed in infinite groups of points, each group consisting of N points F 1 , ... F N , N ⁇ 2, (modulus N is constant integer).
  • Axis Y c is orthogonal to a plane r in a point C inside the region defined by curve L. Point C is distinct from baricentre 0 of N-polygon F i .
  • L being a closed curve, function f ( ⁇ ) will be defined for any value of a; then f ( ⁇ ) is a continuous function.
  • a system of N equalities expressed by f, a, ⁇ 1 , ⁇ 2 , ... ⁇ N is valid according to Carnot's theorem, to determine side length W ( ⁇ )
  • W is the side measure of one family of equilateral N-polygons P i .
  • Figure 1 shows a machine in the general case: rotor axis Y o is orthogonal to reference plane r in baricentre O. Baricentre 0 is different from pole C, Y o //Y c . Angles P i P ⁇ i+1 P i+2 vary with anomaly a.
  • Machines with rotor vertices on points Q i are characterized by the non-deformability of the rotor and rotoid curve R N is defined by radius CQ, Figure 5, angles Q i Q ⁇ i+1 Q i+2 are constant.
  • Machines characterized by these trajectories of rotor vertices have axis Y o coinciding with axis Y c and with the symmetry axis of stator cavity U.
  • equations g ( ⁇ ) of formula (2) have the property of invariant length W:
  • equation g ( ⁇ ) defines rotoid curves R N of the machines shown in Figure 3, in which the four points P, are vertices of a family of rhombuses P, with baricentre in pole C. Vertices P, are on rotoid curve R 4 defined by:
  • An inextensible connection (bar 7) joins the middle points of rotor sides P i P i +1 and P i+2 P i+3 to transmission shaft 14.
  • bar 7 has a centre of rotation coinciding with baricentre 0 of rhombus P i .
  • point D need not be on a circumference.
  • the rotor of the cyclic volume machine may be used as a tool to rectify perimetral surface M of inner stator cavity U.
  • Perimetral surface M of stator cavity U may be radiused with stator bases according to a complementary profile to the profile of rotor surface E.
