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 materializing two axes parallel to those of the cylinders. defining the shape of the piston and the capsule, this third member being in rotoidal connection around its axes, respectively with the piston and with the capsule.
  • 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.
  • volumetric machines with planetary movement which are described in the article cited above are distinguished from the machines according to the invention by the geometry of the capsule and that of the piston.
  • 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 (i.e. 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.
  • one of the organs, male or female has a director D1 which identifies with a curve uniformly distant from a closed hypertrochoid, presenting neither double point nor point of cusp, excluding hypertrochoids degenerated into hypotrochoids, epitrochoids or peritrochoids. It is clear that while remaining within the scope of the invention, the director D1 can also be at zero distance from such a hypertrochoid and therefore identify with it.
  • the definition of hypertrochoids is specified in patent FR-A-2,203,421.
  • 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.
  • Expression (1) provides a relationship between ⁇ and ⁇ which, introduced in expression (2), allows the definition of Z2 as a function of a single kinematic parameter ⁇ or ⁇ .
  • ⁇ * ⁇ corresponding to a particular position ⁇ * of D1
  • Z2 corresponds to the interior and exterior envelopes, that it is advisable to separate these two envelopes and to use one of them according to the family of machines that one wishes to produce. This separation can for example be based on the comparison of the radii of curvature at the contact points of D1 and D2.
  • the relative planetary movement can be achieved by a constant ratio transmission and in particular by an internal gear with parallel axes, the wheels E1 and E piston of which are respectively integral with the pistons and capsule and whose primitive radii are respectively equal to R1 and R2.
  • 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. Whether it is adjustable or not, 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).
  • a particularly interesting group of machines belonging to family I is the one whose director D1 answers the following equation in the complex plane: in which Z1 designates the affix of the generator point of the director D1, each point being specified by a particular value of the kinematic parameter ⁇ whose range of variation is between 0 and 2S ⁇ to traverse the curve once, S is a number integer which designates the order of symmetry of D1 with respect to the origin of the complex plane and is chosen arbitrarily, expi represents the imaginary exponential function, E and R m are two lengths chosen freely provided that the corresponding curve has neither point double, no cusp, which indirectly limits the value of the E / R m ratio .
  • 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 digital simulation on a computer.
  • Figures 9 and 10 show a compressor where the capsule is stationary and where the third member is a bent shaft.
  • FIGS. 11 and 12 represent a machine where the third stationary member is identified with a casing surrounding the capsule, with which the piston and the capsule are in rotoid connections.
  • 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.
  • D2 has three line segments of length equal to (1 + S) 2E arranged at 2 ⁇ / (S + 1) with respect to each other.
  • connection of these three line segments is obtained for other relations between ⁇ and ⁇ satisfying relation (1). There correspond three arcs with variable curvature.
  • 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 lines and can, outside of these segments, depart from the director D2 provided that it is external to it. In this case, the contacts of the director of the capsule with the director D1 of the piston are always made at three points and the relative planetary movement of the piston-capsule can be carried out directly by these contacts, without the need for recourse. to a gear materializing the wheels E1 and E2.
  • 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.
  • D1 is the piston
  • the corresponding machine belongs to family I.
  • D1 is the capsule
  • the corresponding machine belongs to family III.
  • 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.
  • D1 is the piston
  • the corresponding machine belongs to family II.
  • 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 working chambers of the compressor. 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 drive side.
  • Figure 12 is a section through the machine through a plane containing the axes of the two rotoid connections.
  • 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 housing.
  • 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 by the light 140 connected in the flange 230 to the tube 340 and the exhaust is made by the light 150 connected to the tube 350 in the flange 330.
