Definitions

  • the invention relates to a volumetric roller motor receiving energy from any type of fluid, liquid or gaseous.
  • the cell thus defined is therefore the volume in which the working chambers circulate and evolve.
  • a motor comprising cells in number k necessarily comprises k rotors wedged on the same shaft as well as a stator made up of k stator rings and watertight bulkheads in number (k - 1), each of which separates two cells and the two flanges acting as end partitions.
  • Roller machines operating as liquid pumps have been described, constructed and used; they have a distribution similar to that of vane machines and rollers with a large clearance in their groove, the passage of the roller from one face to the other of the groove allowing it to play the role of an internal distribution member, avoiding in principle that a certain volume of liquid may, at one point in the cycle, be enclosed in a working chamber whose volume is decreasing.
  • KLESSIG differs from the engine presented here by the organization of its distribution, which remains close to that of a vane engine: KLESSIG also points out that the driving elements are, in its engine, either pallets or rollers.
  • the distribution comprises two intake ports in one flange and two exhaust ports in the other flange or two intake ports symmetrically split in the two flanges so as to ensure the balance of the axial forces due to the fluid on the rotor and two exhaust lights located in the stator ring.
  • intake and exhaust ports are located differently from the geometrical location described by the contacts that a roller can have with its groove during a complete revolution of the rotor when this roller is otherwise kept in contact with the surface. stator.
  • the geometrical location in question consists of the set of two very close regulated surfaces, closed on themselves, corresponding respectively to the contact with the thrust face and with the pipe face.
  • the intake ports are located entirely within this geometric location, the entire exhaust ports outside this same geometric location.
  • the first originality of the distribution using the lights thus located is as follows: a successive intake and exhaust in the direction of movement of the rotor are necessarily closed and opened respectively by the driving face of a groove and by the corresponding roller.
  • This organization of the distribution therefore differs fundamentally from that of a pallet machine, where a successive admission and exhaust in the direction of movement are necessarily closed and opened respectively by two successive pallets delimiting a working chamber.
  • each exhaust light is located angularly so as to be opened by the roller operating when this is located in the vicinity of the position which corresponds to its maximum distance from the axis of the rotor (at its maximum “exit"), and preferably exactly in this position.
  • each intake lumen is also angularly located so that its closing by the driving face of the groove of the operating roller is ideally carried out at the same time as the opening of the lumen. exhaust by roller; in an engine receiving its energy from a gaseous fluid, closing the intake can, by an appropriate angular offset from the ends of the lights, precede the opening of the exhaust, so as to allow a certain expansion of the admitted gas.
  • the third originality of the distribution relates to the conditions of opening of each intake lumen: this opening is made by the pushing face of a groove, and, due to the location of the intake lumen, the fluid under pressure is necessarily admitted between the bottom of the groove and the level of contact that the roller has, at this instant, with its groove if it is otherwise in contact with the stator surface.
  • the roller is in principle driven, it tends to bear on the driving face of its groove: arrangements must therefore be made for the flow of the fluid at high pressure is applied to the expanding working chamber.
  • an open channel is provided in the driving face of the groove, of sufficient cross-section so that the resistance to the passage of the fluid through this channel is less than that which it would meet when passing between the roller supported on the driving face of its groove and the pushing face of the latter, towards the exhaust opened in the meantime by the preceding roller.
  • roller motors according to the invention appear in practice to be relatively insensitive to the local shape of the stator curve as long as it is continuous: the various curves of general elliptical shape which are used in machines with palettes give little different results here, and are therefore directly transferable.
  • stator surface can then be rectified by simple mechanical generation on known machines.
  • the parameters to be imposed on the generation of a cylindrical surface having a Polygon P2 profile as its director are limited to the mean radius and to the eccentricity of the profile: to use this profile as the stator curve of an engine according to the invention, it It suffices to impose an eccentricity equal to half of the maximum stroke desired for the rollers and an average radius equal to that of the rotor profile increased by half the maximum stroke imposed on the rollers.
  • the number of rollers is in principle arbitrary, as long as it is odd, but it is disadvantageous that more than two rollers can be put simultaneously at the admission into each of the half-machines separated by the main plane of the corresponding stator surface at its smallest curvature.
  • rollers originally present in their groove in order to satisfy as easily as possible, even after a certain wear, the condition imposed by the third characteristic of the distribution described above.
  • the wear of the rollers can have an unfavorable influence on the operation of the engine when it becomes very important: in any case, the materials constituting the various elements of the machine must be chosen so that the wear on the rollers is as low. as possible.
  • This effect can be obtained by angularly shifting the rotors on their shaft without shifting the stator rings, or by angularly shifting the stator rings without shifting the rotors, or by combining the two possibilities.
  • the motor can or must comprise at least two identical cells
  • a variant can be made to the invention, according to which the number of rollers n r * guided by each rotor is even.
  • the advantage of this variant lies in the fact that because of the even number of rollers, the radial resultant of the pressures of the fluid on each rotor is permanently zero: there is therefore no radial force due to the fluid on the bearings of the machine. If, in addition, the lights of the same name are located in the partition, the axial thrusts on the rotors can also be balanced and the bearings are then withdrawn from any force due to the fluid.
  • the machines according to the invention in which the closing of an intake and the opening of the consecutive exhaust are simultaneous or almost simultaneous, can be used as pumps with a simple transfer, whatever the fluid pumped, if they are driven by any motor in the opposite direction to the engine, the intake and exhaust ports being thus reversed.
  • Such pumps do not experience any undesirable overpressure, even when the pumped fluid is a liquid, but they practically require to be provided with a non-return valve on each of the exhausts.
  • the motor comprises a stator consisting of the flanges 1 and 2, here produced in two parts, and of a stator ring 3.
  • the rotor 4 is fixed on the shaft 5, in rotunda connection with the stator by means of the bearings 6 and 7.
  • the rotor which turns in the direction of the arrow, has seven grooves such as 8, guiding seven rollers such as 9, 10 and 11.
  • the two intake ports 12 and 13 are located in the flange 1 and the two exhaust ports 14 and 15 in the flange 2.
  • the roller 10 In the represented position of the rotor, the roller 10, at the end of the motor period, is about to open the exhaust port 14, and the pipe face 16 of its groove is about to close the port light 'admission 12; the roller 9 is about to become a motor and the intake port 12 already feeds the expanding working chamber 17 through the open channel 18 provided in the pipe face of its groove.
  • the roller 11, applied to the thrust face 19 of its groove is in full period of movement.
  • the stator curve 20 is here a Polygon P2 profile.
