Definitions

  • the invention relates to the field of undulating membrane circulators.
  • An object of the invention is to provide a means of controlling parameter(s) influencing the vibrations of the circulator.
  • This circulator is essentially characterized in that it also comprises a device for detecting at least one value representative of a displacement of the membrane relative to the body, this detection device being functionally connected to a unit of power supply to the motor, this power supply unit being arranged to deliver at least one electric power supply signal to the motor as a function of a detection signal delivered to the power supply unit by said detection device, this detection signal being a function of said at least one detected value.
  • the detection of a value representative of the displacement of the membrane then the generation of a detection signal representative of this at least one detected value and finally the control of the motor via said at least one electric power supply signal of the motor itself function of a detection signal, allows control of the operation of the motor and therefore makes it possible to act on the movement of the membrane in the body.
  • This control allows servoing of the circulator according to the displacement of the first edge of the membrane which, in addition to controlling the frequency and/or the amplitude of displacement of the edge of the membrane, allows the hydrodynamic characteristics of the circulator to be varied. at each instant, i.e. the flow rate of fluid pumped, the pressure difference between the inlet and the outlet of the chamber, the curve of the evolution over time of the flow rate and/or the pressure in bedroom exit.
  • the actuation mechanism is arranged to define a maximum MAX amplitude of the reciprocating movement of the first edge of the variable membrane in function of said at least one power supply signal delivered to the motor.
  • the motor is thus a motor whose maximum amplitude of oscillation/maximum travel of the rotor relative to the stator is variable as a function of said at least one electric power supply signal of the motor.
  • the term rotor designates the part of the motor which is movable relative to the stator without implying that this mobility is necessarily a rotation.
  • the rotor can be linearly or substantially linearly movable with respect to the stator.
  • a linear motor is any motor whose rotor, over a complete motor cycle, moves relative to the stator along a trajectory which extends along a line segment, passing through the extremities of this straight line segment and without ever deviating from this straight line segment by a distance greater than 10% of the length of this straight line segment.
  • the supply unit can thus adjust the distance between the edge of the membrane and the wall of the chamber to vary the "occlusivity", that is to say the minimum fluid passage section authorized by the membrane every moment of its undulation.
  • This minimum authorized fluid passage section being the smallest authorized passage section at a given instant between the fluid inlet opening and the fluid outlet opening. It is also noted that by adjusting the maximum amplitude of displacement of the membrane as well as its oscillation frequency and by following a movement imposed in the time of displacement of the first edge of the membrane with respect to the support, the unit of power supply can define the variation of the wavelength transiting along the membrane and through therefore the number of inflections of the wave traveling along the membrane in the chamber.
  • the circulator according to the invention by allowing regulation of said at least one motor supply signal taking into account the value or values detected and representative of the displacement of the first edge of the membrane, makes it possible to regulate the amplitude of displacement of the first upstream edge and/or the oscillation frequency of this first edge and/or the force applied to this first edge of the membrane and/or the displacement curve over time of this first edge of the membrane.
  • the circulator makes it possible to control the value of the minimum passage section through the chamber and the number of inflections of the membrane, which plays on the flow rate of fluid and the pressure of fluid delivered by the circulator.
  • a linear alternating motion designates a displacement of a given point or object which, over a complete cycle of the alternation, follows a trajectory which extends along a segment of line, passing through the extremities of this line segment, without ever deviating from this line segment by a distance greater than 10% of the length of this line segment.
  • the first membrane edge is stiffened by a reinforcement in order to limit its deformation when this first edge is moved following the reciprocating movement. There is thus a uniform displacement of the first edge of the membrane, which limits the appearance of secondary waves on the membrane.
  • the circulator according to the invention has a device 5 for detecting at least one value representative of a displacement of the membrane 3 relative to the body 2.
  • This detection device 5 is functionally connected to a power supply unit 6 of the motor which can be an inverter. Depending on the case, this inverter can be connected to a direct or alternating current, single-phase or polyphase power supply network.

  • the invention makes it possible to regulate the motor according to the actual displacement of the membrane in the chamber, this displacement being estimated by measuring at least one value representative of this displacement by said detection device 5.
  • the movement of the membrane can be controlled so that the circulator adopts an expected operating point.
  • the operating point is a state of various operating parameters of the circulator at a given time of operation.
  • the circulator can be controlled to limit the vibratory level induced during its operation and thus limit the energy lost by contact of the membrane against the wall of the chamber and/or the energy lost in the form of shock of the membrane against the wall.
