Definitions

  • the present invention belongs to the pumps and motors sector, and more specifically to that of fluid machines. It provides a new tool system that can interchangeably operate as a motor machine, generating machine or both in unison. All this only depending on the direction of energy transfer between the machine and the fluid.
  • the fluid machines can be classified into four groups:
  • Generating machines They consume mechanical energy by transferring it to the fluid, such as pumps, fans and compressors.
  • Motor machines They extract energy from the fluid by converting it into mechanical energy that can be transmitted to an electric generator, or directly to a vehicle, a machine tool, etc.
  • Reversible machines They can function interchangeably as generators or motor, such as the Turbine-Pump groups that are used in the accumulation plants by pumping.
  • Transmitting machines They allow to transmit energy by means of a fluid, being constituted by a combination of motor and generating machines. Typical examples are couplings, torque converters, hydraulic and pneumatic transmissions, etc. According to their operating principle, fluid machines can be classified into two groups:
  • Dynamic machines They are based on the exchange of movement between the machine and the fluid. They are generalized in the so-called rotodynamic machines (Turbomachines), which exchange energy with the fluid through a variation of kinetic moment.
  • Volumetric or positive displacement machines They are based primarily on fluid and static principles, characterized by confining certain fluid mass in a compartment that moves from the machine's feed zone to the discharge zone.
  • Dynamic generating machines are characterized by their high displacement capacity and are the most widespread in the industry because they adapt to almost any use, constituting at least 80% of the worldwide pump production. It is justified by moving a greater quantity of liquid than the volumetric ones, lacking valves and providing a uniform flow free of low frequency pulses.
  • the volumetric or positive displacement pumps have a more specific use irreplaceable by the previous ones. They are more useful for manual operation, extremely high pressures, relatively low and controlled discharges, low speed, variable suctions and deep wells without requiring high flow rates. They are excellent vacuum pumps and handle viscous fluids well.
  • the present invention relates to a new volumetric fluid machine system that It can operate as a generating machine, motor machine or both at the same time, characterized by having a single rotor that moves radially and axially adjusted to the housing where the holes of the entry and exit tracks are arranged, which can be located both in the radial as axial faces of the housing, even in both to choose the most suitable at the time of installation.
  • the rotor describes a translational movement adjusted to the walls of the housing, which by its geometry guarantees at all times to keep the entry and exit paths isolated. Being the rotor of a single piece or element can be designed with a multitude of silhouettes without breaking with its principle, giving rise to several compartments or independent chambers in tune with the housing that enhance its productivity and performance.
  • the adjustment that guarantees the tightness and isolation between the inlet and outlet tracks is produced by radial and axial coupling of the rotor with the housing.
  • the combined geometries of the rotor and the housing guarantee that at no time there are absences of radial and axial contact, providing absolute tight sealing to the system.
  • the principle of operation of the system is such that it does not condition the design to regular symmetries or geometries.
  • Admission (Suction) and continuous evacuation assisted by the translation of the rotor permanently adjusted radially and axially to the housing occurs at any interval in the sequence of a rotor translation cycle.
  • the input and output circuits follow a uniformly increasing and decreasing cycle respectively, which can be reversed by simply changing the direction of translation of the rotor.
  • the rotor translation system is attended by guiding means that guarantee this type of displacement.
  • an object of the present invention is to provide a high performance and low cost multipurpose fluid machine system that exceeds performance at what is currently included in the state of the art.
  • Another object is to combine in a single system the benefits that separately characterize the current volumetric and rotodynamic fluid machines.
  • valve system would be a means for enhancing the resources of the present invention.
  • the present invention is capable of covering the two market niches that up to date independently occupy the different known fluid machine systems (Rotodynamic and Volumetric), further enhancing the benefits that each of them can offer. Unless otherwise indicated, all technical and scientific elements used herein have the meaning normally understood by a person skilled in the art to which this invention pertains.

  • the rotor describes a translational movement adjusted to the walls of the housing, which by its geometry guarantees at all times to keep the entry and exit paths (3) and (4) or intake and expulsion isolated.
  • the adjustment that guarantees the tightness and isolation between the inlet and outlet tracks (3) and (4) is produced by the radial coupling that is schematized as a radial section in ( Figure-3), representing as (1) the housing , (2) the rotor, and the arrows being the ones that indicate the most unfavorable and leakage point due to the different pressures that will exist between the intake and expulsion channels (3) and (4).

  • the geometry of the rotor (2) and therefore the housing (1) can take many forms without altering the principle of the system. In ( Figure-5) we show five examples of silhouettes that the system could adopt, being able to appreciate that this figure can be extended to what the imagination itself wants to achieve.
  • the rotor translation system (2) is guaranteed by at least one guiding means (5) that forces this type of movement, based on the eccentric rotation that would be produced by rotating a support or shaft located in the rotor (2) around a support or shaft located in the housing (1).

It shows in diagrams (Fig-8c) a radial section, (Fig-8d) axial section and (Fig-8e) perspective of what being a single element is composed of two axes (10 and 1 1) displaced from each other to provide eccentric displacement.
  • the translation guide means (5) comprise any system that already exists in the state of the art that provides rotation of a support around an axis (crankshaft effect), the detail set forth in ( Figure-8) being only one Shallow but practical sample to help understand the type of displacement.

  • the present invention is completed by demonstrating that it is not a single arc-shaped rotor (2) with a pair of input tracks -output (3-4) (Admission- Expulsion), but a single rotor (2) with a design that can contain from one to several arches with one or several pairs of input-output tracks (3-4), not being a condition it is mandatory that the arcs be geometrically equal in the case of more than one, just as the quantity of them does not have an even or odd obligation.
  • the guiding means containing the driving axles (10) that guide the translation of the rotor can be from one to several without a specific location, but the designer is the one who chooses the quantity and its location by adjusting at your own discretion and requirements.
  • FIG.-12c shows the housing (1) that would correspond to the rotor of ( Figure-12a) distinguishing a pair of input-output tracks (3 and 4), which although it was previously justified that it was indifferent to locate them in the axial or radial face of the housing (1), in ( Figure-12c) we show the option where the entry (3) and exit (4) tracks are located on one or both axial faces (12) of the housing (one).

Abstract

L'invention concerne une machine à fluide polyvalente qui comprend un rotor (2) accouplé radialement et axialement à l'intérieur d'un bâti (1), la géométrie du rotor (2) en harmonie avec celle du bâti (1) pouvant être conçue avec une multitude de silhouettes constituées de paires d'arcs, non conditionnés à des formes rectangulaires, cylindriques ou à des symétries. Ainsi, aussi bien des paires de voies d'entrée-sortie (3',3''-4',4'') que des paires d'arcs forment le rotor (2). Le rotor (2) obéit à un mouvement translationnel assisté par des moyens de guidage (5) logés dans n'importe quelle partie de ce dernier (2). Seulement en interagissant avec l'alimentation des voies d'entrée (3',3'') ou de sortie (4',4''), le rotor peut fonctionner indistinctement comme machine génératrice, motrice, réversible ou de transmission, y compris à la fois comme machine motrice et génératrice sans d'axes qui sortent à l'extérieur du bâti (1).
