Definitions

  • the invention generally relates to an oscillating-rotational subassembly and an oscillating-rotary pumping device for volumetric pumping of a fluid.
  • volumetric pumping devices for production and / or reconstitution (liquid-solid or liquid-liquid mixtures) and / or administration (injection, infusion, oral, spray, etc.) is known, in particular for medical, aesthetic, veterinary applications.
  • precise quantities of fluid for example to a container, or to be administered directly to a patient via an injection device, must be pumped in a controlled manner, infusion or other suitable device.
  • the devices of the "push syringe" type require the pre-filling of the syringe. This filling is, most of the time done manually, which represents a laborious operation to achieve, especially since this filling requires the respect of specific precautions to ensure the integrity of the liquid and the safety of the personnel.
  • Cartridge type devices require the use of silicone to lubricate the cartridge body and thereby facilitate sliding between the generally elastomeric piston and the cartridge body generally made of glass or plastic.
  • the presence of silicone in direct contact with the fluid generates problems of stability of the molecules during storage in the cartridge before use.
  • Peristaltic pumps are bulky and bulky. Moreover, the operating principle of these peristaltic pumps requires them to have a flexible hose that prevents reaching high pressures. Due to the flexibility of the pipe, the volumetric efficiency (actual flow / demand flow) changes significantly with the pressure variations of the output fluid and quickly degrades the dosing accuracy without the help of auxiliary sensor (eg a flow sensor ). Thus, the operating pressures of such peristaltic pumps are typically less than 5 bar which limits their implementation with viscous liquids. In addition, it is common that this type of pump generates tiny air bubbles in the fluid, which can have an unacceptable effect. Finally, the rapid aging of the mechanical properties of the pipe poses problems of modifying the performances and / or the reliability over time of this type of pump. The same type of disadvantages are encountered with diaphragm pumps.
  • flap pumps It is also possible to use flap pumps. However, the passage of the fluid is then free between the inlet and outlet ducts in the case where the inlet is in overpressure with respect to the outlet. Also, the valve pumps do not offer the possibility of having a neutral position in which any circulation of the fluid is prevented. Finally they are not reversible.
  • the fluid can be sucked by one of the conduits during the intake phase, stored in the working chamber during the switching phase, and then discharged by the other conduit during the discharge phase.
  • this rotary tilt-rotary pumping device imposes a good seal between the piston and the cavity, which requires severe manufacturing tolerances, difficult to meet without significant additional cost of production and / or significant friction penalizing the energy efficiency of the rotary tilt-rotary pumping device.
  • the object of the invention is to overcome these drawbacks by proposing an oscillation-rotary subassembly for volumetric pumping and a volumetric oscillation-rotary pumping device of a moderate manufacturing cost with a limited number of parts, reversible, precise , allowing the transfer of viscous liquid even at high pressure, and having a good fluid and energy efficiency.
  • the idea underlying the invention is to provide a seal between the piston and the body, this seal having a particular shape to ensure effective sealing while limiting friction to improve energy efficiency. and increase the flow accuracy of the tilt and turn subassembly.

For this purpose, it comprises two stages, a first stage similar to that of the oscillating-rotary subassembly 1 and a second stage comprising two conduits 111, 112, a working chamber 131, a groove 122, a recessed area 129 such that those of the first floor.
  • each pair of pipes 11, 12 called intake and discharge corresponds to a single groove 22, 122.

  • the body 102 also comprises an annular groove 135, coplanar with the shoulder 106 separating the cavity 110 and the bore 107, oriented towards the inside of the body 102 and intended to receive, for example, a complementary seal 36 or any other sealing member ensuring the seal between the piston 103 and the body 102.
  • a stage is in the admission phase ("Adm phase") with the groove 22, 122 facing the duct 11, 111 said admission
  • the other stage is in the discharge phase ("phase Ref") with the groove 22, 122 facing the duct 12, 112 called discharge ( Figures 16, 17, 19 and 20 ).

  • the so-called inlet ducts 11, 111 of each stage can be fluidically connected to a common inlet of the same fluid and the so-called discharge ducts 12, 112 of each stage can be fluidically connected to a common outlet of the same fluid.
  • the double-acting oscillating-rotational subassembly can advantageously be used to produce mixtures using a stage for a first fluid and another stage for a second fluid, the pipes 12, 112 known as delivery pipes of each stage being for example connected to the same container for receiving the mixture obtained.
  • the dosage of the mixture obtained can be varied.
  • the flow rate of the pumping device incorporating such a double-effect oscillo-rotary subassembly 101 will be increased, with a pulse frequency that is twice as high, relative to a single-acting oscillating-rotary subset 1. .
  • the conduit 12 said delivery of a stage can be fluidly connected to the conduit 11, said admission, the other floor.
  • the sucked fluid passes successively through the working chambers 31, 131. It is possible to accumulate in cascade the discharge pressures generated by each stage.

  • the two phases of admission of the two stages are concomitant with each other, and the two phases of discharge of the two stages are concomitant with each other.
  • the flow rate of the pumping device incorporating such a double-acting oscillating-rotational subassembly 101 will be doubled with an identical pulse frequency with respect to a single-effect tilt-rotary subassembly 1.
  • each so-called intake duct is angularly offset from the corresponding discharge duct by a predetermined angle
  • the grooves are angularly offset from each other by the same predetermined angle
  • the recessed areas are also angularly offset from one another. same predetermined angle.
  • the fluidic connections through the so-called intake ducts and the so-called intake ducts are in separate longitudinal planes angularly offset from the predetermined angle. This angle can be chosen to facilitate the spatial organization of the fluidic connections.
  • the oscillating-rotary subassembly 1, 101 according to the invention is simple to manufacture with a limited number of parts.
  • the seal makes it possible to limit the geometrical constraints to be respected and facilitates the manufacture of the oscillating-rotational subassembly 1, 101. It is also easier to assemble and the recessed area 29, 129 makes it possible to improve its energy efficiency.
  • the oscillating-rotary subassembly 1, 101 makes it possible to ensure a precise flow independent of the user and / or the viscosity of the fluid. It can be coupled to an angular position sensor.
  • the oscillating-rotational subassembly 1, 101 according to the invention is reversible, simply by inverting the direction of rotation of the piston 3, 103.
  • the duct 11, 111 called admission becomes duct 12, 112 called repression and vice versa.
  • the mechanical decoupling between the piston 3, 103 and the drive means make it possible to obtain a disposable tilt-rotary subassembly while the driving part is reusable. This ensures, at lower cost, the sterility of the tilt-rotary subassembly 1, 101 by replacing it between two uses.
  • the fluidic portion of the tilt-rotary pumping device is to be renewed, the motorization and control parts being kept between two uses.
  • the oscillating-rotational subassembly 1, 101 prohibits any fluid flow with the ducts 11, 111, 12, 112 called inlet and discharge during the switching phases, without creating an overpressure effect. or depression by hydraulic blockage during these phases. It also allows to limit the dead volume.
