Definitions

  • the invention relates to a volumetric machine comprising a cylindrical capsulism essentially consisting of a cylindrical piston (male organ), a cylindrical capsule which surrounds it (female organ) and a third organ in rotoidal connection with the male organ. around the axis thereof, in rotoidal connection with the female member around the axis thereof, the shape of this third member imposing the parallelism of these two axes.
  • the cylinder defining the shape of the piston has an order of symmetry with respect to its axis equal to s P , that of the capsule an order of symmetry equal to s C ; s P and s C are chosen so that these values differ by one.
  • the geometry of the piston and the capsule are chosen so that there is contact between these elements.
  • the axis of the cylinder defining the interior shape of the capsule must be coincident with the axis of its rotoid connection with the third member.
  • the axis of the cylinder defining the external shape of the piston can be chosen arbitrarily, provided that it is parallel to the axes of the third member.
  • the axis of the cylinder defining the internal shape of the capsule can be chosen arbitrarily, provided that it is parallel to the axes of the third member.
  • either the piston or the capsule has a director which is a shortened hypotrochoid or an epitrochoid, or a curve uniformly distant from a non-elongated hypotrochoid or an epitrochoid (that is to say ordinary or shortened). All these curves have only one or two shape parameters which can only be chosen between close limits. They do not make it possible to satisfy all the technological constraints, as is desired in modern machines.
  • machines according to the invention can be derived from machines belonging to one of the four preceding families. Indeed, one can use a director D2 of which at least a part is identified with the envelope of D1 in its movement relative to D2 and of which at least a part is external to this envelope in the case of families I or II and is inside this envelope in the case of families III or IV, the different parts connecting to define a closed curve.
  • these machines transform fluid energy into mechanical energy or vice versa.
  • Mechanical energy is exchanged with the outside by a tree.
  • this tree identifies with it and in this case it is bent.
  • this shaft of rectilinear shape, is distinct from it and it is integral with the capsule or the piston.
  • the fluid energy is introduced and extracted from the machine by a set of valves, lights and / or valves arranged in the capsule and / or the piston, according to the conventional techniques used in known volumetric machines and directly applicable by the skilled in the art.
  • These fluid distribution devices can possibly be adjustable to allow a variation of the filling.
  • the distribution of the fluid can be adapted to the nature thereof (incompressible or compressible fluid) and to the direction of energy transformation (fluid generating machine: compressor or pump and machine generator of mechanical energy: motor). It will be observed that, in the particular case of machines where the third organ is immobile, when these machines belong to families I or II and when the director D2 is not completely identified with the envelope of D1 in the relative planetary movement, the part of the director D2 which is external to this envelope can be deleted, the different parts of the director D2 which identify with the envelope are then disjoint and the director no longer constitutes a closed curve.
  • a fixed casing which identifies with the third member surrounds the capsule to ensure sealing, the capsule and the piston ensuring the distribution of the fluid, by discovering and periodically closing in their absolute rotational movements, a light d at least one inlet and at least one exhaust light fixed in the machine.
  • Figures 1 to 4 schematically represent a machine according to the invention.
  • Figures 5 to 8 schematically show another machine according to the invention. These representations are the result of a computer numerical simulation.
  • Figures 9 and 10 show a compressor where the capsule is stationary and where the third member is a bent shaft.
  • Figures 11 and 12 show a machine where the third body, stationary, identifies with a housing surrounding the capsule, with which the piston and the capsule are in rotoid connections.
  • the shape of the interior surface of the capsule and of the exterior surface of the piston correspond to the diagrams presented in FIGS. 1 to 4.
  • the capsule (10) of director D2 which surrounds the piston (11) of director D1.
  • Figure 3 shows the director D1 (12)
  • Figure 4 shows several positions of D1 relative to the capsule, the latter not being shown for clarity.
  • Sa length is equal to 4A, i.e. (1 + S) 2E.
  • D2 has three line segments of length equal to (1 + S) 2E arranged at 2 ⁇ / (S + 1) with respect to each other.
  • the connection of these three line segments is obtained for other relations between ⁇ and ⁇ satisfying relation (1).
  • relation (4) When relation (4) is verified, there exist, for all the angular positions of the piston defined by ⁇ , three points of contact with the directrix defined by the three corresponding values of l and therefore of ⁇ .
  • a value of ⁇ and a value of ⁇ verifying one of the determinations of the relation (4) define a point of contact located on one of the three line segments of D2 and, for a particular value of ⁇ , at each determination of the relation (4), corresponds a line segment of D2. It follows that on the one hand the director of the capsule must identify with these three straight segments and can, outside of these segments, depart from the director D2 provided that it is external to it.
  • the director D2 of the corresponding capsule has a symmetry of order 2.
  • the resolution of the relation (1) for all the relative positions piston-capsule shows that one has permanently three contacts between D1 and its external envelope D2. This leads to the existence of three working chambers for the fluid.
  • FIG. 4 represents the planetary movement of a curve D1 of order of symmetry equal to 2, represented in FIG. 3.
  • the planetary movement is characterized by the rolling of a circumference C1 of radius equal to 2E (with which is associated the director D1) on a fixed circumference C2 of radius equal to 3E.
  • FIG. 4 we can observe the outer and inner envelopes integral with this fixed circumference C2. These envelopes both have an order of symmetry equal to 3.
  • FIG. 8 represents the planetary movement of a curve D1 of order of symmetry equal to 3, represented in FIG. 7.
  • the planetary movement is characterized by the rolling of a circumference C1 of radius equal to 3E (with which the director D1 is associated) on a fixed circumference C2 of equal radius to 2E.
  • C1 of radius equal to 3E (with which the director D1 is associated)
  • C2 of equal radius to 2E.
  • FIG. 8 we can distinguish the outer and inner envelopes integral with this fixed circumference C2. These envelopes both have an order of symmetry equal to 2.
  • the corresponding machine belongs to family IV.
  • Figures 9 and 10 show a cross section and an axial section respectively, in a compressor where the compressed fluid is sufficiently lubricating to allow the piston-capsule couple to directly carry out the planetary movement.
  • the fluid is admitted into the compressor by the valves (41,42,43) located in the rear flange (101) of the capsule (10) and escapes therefrom by the valves (51,52,53) located in the part tubular (100) of the capsule (10).
  • Controlled shutters such as (61), located in the front flange (102) of the capsule (10) allow maintenance at the intake pressure of one, two or three compressor working chambers. It is thus possible to regulate the flow in three steps and operate the compressor at zero flow without ceasing to drive it, thus avoiding the use of a clutch interposed between the bent shaft and the pulley or avoiding stopping the motor when it must continue to drive other machines.
  • Figure 11 is a machine which comprises a piston and a capsule, in rotoidal connection with a fixed casing; this view in the direction of the axes of the rotoid connections represents the machine without the flange located on the side of the drive.
  • Figure 12 is a section through the machine on a plane containing the axes of the two rotoid connections. In this section, the piston 11, the capsule 10 and the casing made up of a tubular part 130 and two flanges 230 and 330 are distinguished.
  • the piston 11 is, in the machine shown, in one piece with the shaft 111 whose bearings 112 and 113 materialize the rotoid connection of the piston 11 with the flanges 230 and 330 of the casing.
  • the capsule 10 is in rotoidal connection by the plain bearing 110 with the tubular part 130 of the casing.
  • the fluid is admitted into the machine through the light 140 connected in the flange 230 to the tube 340 and the exhaust is made through the light 150 connected to the tube 350 in the flange 330.
