Definitions

  • the machine object of the present application overcomes one or more of the aforementioned drawbacks.
  • the invention relates to a pump, characterized in that it comprises at least one machine according to the invention.
  • the invention also relates to a compressor, characterized in that it comprises at least one machine according to the invention.
  • the invention finally relates to a hydraulic, pneumatic or thermal engine with external combustion, characterized in that it comprises at least one machine according to the invention.
  • the rotor is composed of a disk (1), two concentric shoulders (4 and 8) disposed on either side of said disk and two fixed pallets (3 and 7) arranged diametrically opposite from each other; other of said disk each against a face of said disk and contiguous to the periphery of said shoulders, so as to obtain a rotationally balanced assembly, said rotor being machined in one piece or made using components assembled, said rotor being housed in a cylindrical chamber (2) arranged in a stator, the stops (5 and 6) are housed in the stator, movable and actuated by mechanical or hydraulic or pneumatic or electrical actuating means or by a combination of said means disposed at a distance from said cylindrical chamber, so that the working volume is free of any form of lubrication and can operate dry and at high temperature, so as to allow a rotation in continuous said rotor, said stops being positioned very close to said shoulders during the working phase, so as to generate volume variations between said blades or vanes and said stops and returned to
  • the volume generated by revolution of the pallets (3, 7) or torus is not necessarily square or rectangular section as shown. In particular a circular section is possible.
  • the organs of the present device are adaptable according to the section of the torus.
  • the rotor is secured to a shaft (15) and positioned axially on the one hand between the stator lids (12 and 13) integral with the stator (9) and on the other hand between the bearings (10 and 16) to the using spacers (11 and 14) whose length is defined in the range of dimensions, so that the rotor can rotate without coming into contact with said covers.
  • Bearings are the only points that require lubrication.
  • the rotor is positioned at 235 ° in the positive direction and the front stop is in the extended position.
  • the thickness (17) of the abutment (5, 6) is one of the defining features of the seal.
  • the ducts (18 and 19) serve as intake or discharge in the direction of rotation.
  • the rotor is positioned at 270 ° in the positive direction and the stop (6) is in the retracted position in the stator to allow continuous rotation of the rotor.
  • the rotor is positioned at 325 ° in the positive direction and the stop is in the extended position, the ratio of volumes is represented by hatching: the volume (20) is well larger than the volume (21), which is due to the fact that there is only one pallet per shoulder.
  • the crown of the shoulder is of reduced outside diameter while the flanks of the pallet are directed towards the axis of the rotor.
  • the rotor is positioned at 250 ° in the positive direction and the hinged stop (25) is in the extended position.
  • These stops (25) are carried by an axis (26) disposed at a distance from said cylindrical chamber (2) in order to be controllable by mechanical or hydraulic or pneumatic or electrical means or by a combination of said means arranged at a distance of said cylindrical chamber, so that the working volume is free of any form of lubrication and can operate dry and at high temperature, the articulation of said stop around said axis can thus be lubricated independently without influence to inside the said cylindrical chamber.
  • the pipe (24) is rather intended for convey the high pressures, while the pipe (27) is rather intended to convey the low pressures.
  • the arc angle (28) defining the width of the sealing area between a shoulder and a rocker stop is comparable to that bearing the reference (17).
  • the said axis can also participate in positioning the covers relative to the stator.
  • the rotor is positioned at 305 ° in the positive direction and the hinged stop (25) is in the retracted position.
  • the rotor is positioned at 350 ° in the positive direction and the stop (25) articulated in the extended position.
  • a torque represented by the arrow (29) occurs while the pressing pressure causes a reaction represented by the arrow (31) of equal length.
  • the effort is always directed towards the center of the axis (26).
  • the face (30) of the abutment (25) can bear a greater load than the face (32), it goes without saying that it is on this side that must be the said pipe for conveying the high pressures.
  • each hinged stop (25) is controlled by a hydraulic or pneumatic cylinder (34) articulated in the stator (9) so as to be able to follow the curve of the arc defined by the angular displacement of its attachment point (33) on said rocking stop (25), so as to limit the number of friction points.
  • the cylinder (34) and the stop (25) are retracted to allow the passage of the pallet (3, 7).
  • the number of points to be lubricated is three, therefore, counting the two said bearings, it amounts to five, all located at a distance from the work volume.
  • each tilting abutment is controlled by at least one electric motor (35, 38) controlling a worm (36) actuating a sector (37) integral with each of said tilting abutments ( 25).
  • the stop (25) is exit.
  • Efforts are balanced when two electric motors are used. Apart from the points to be lubricated inside the electric motors, the number of points to be lubricated is two. Counting the two said bearings, it amounts to four, all located at a distance from the work volume.
  • the operating clearances (39) are defined such that the characteristics of shapes and dimensions can be measured in a conventional manner while the arithmetic roughness of the facing surfaces (40 and 41) are defined such that the turbulences generated cause the required sealing, the hydraulic diameters being here also measured in a conventional manner.
  • This machine is suitable for producing groups formed of two or more so-called common shaft machines, possibly of different sizes.
  • one of the covers (12 or 13) can be replaced by a partition separating the different work volumes, the number of partitions being defined by the number of working volumes.
  • the two pallets of a machine of the invention may have different dimensions in order to generate two tori of different volumes.
  • the figure 17 illustrates the leakage observed at the pallet (3, 7) in the case of an application to a pump or a compressor: the suction pressure (42) is lower than the atmospheric pressure, so there is a vacuum. The pressure (46) is greater than the atmospheric pressure either because it is necessary to overcome the friction or because it is desired to obtain a pressure on this side of the pallet. Tolerated leaks will compensate for depression (42).
  • the figure 18 illustrates the leakage observed at the pallet (3, 7) in the case of an application to a hydraulic or pneumatic motor: the pressure (51) is greater than the atmospheric pressure because it is desired to generate a motor torque.
  • the pressure (47) is greater than the atmospheric pressure because it is necessary to overcome the friction due to the backflow. Leaks will be fully or partially balanced on both sides of the pallets.
  • the parts of the rotor and / or the stator (9) in relative motion can be constituted (or covered) with a self-lubricating material to withstand accidental friction (for example in the presence of impurities or depending on the nature of the fluid present in the volume of the cylindrical chamber (2)).
