Definitions

  • the present invention relates to a Stirling machine comprising a transfer piston and a movable member of a generator or an electric motor, the transfer piston being mounted in a cylinder, in which it periodically moves a working gas between a an expansion chamber and a compression chamber constituting the working volume of said Stirling machine, respectively associated with two working faces of said transfer piston by passing said gas through a heat exchanger, connected to a heat source, a regenerator and a cooling exchanger connected to a heat sink and resilient biasing means exerting a force on said transfer piston, the ratio of section a C / a E between the two working faces of said piston being ⁇ 0.35 so that its displacement along an axis oriented towards the expansion volume generates a pressure component of said working gas in phase opposite said displacement of said udder ton, so as to transmit between the transfer piston and said movable member all of said mechanical energy produced.
  • this invention relates to a Stirling machine as defined by claim 1.
  • the essential advantage of the invention over two-piston Stirling machines according to the state of the art lies in the fact that the resonant piston no longer needs to be controlled, to eliminate any active servocontrol requiring electronics complex.
  • the volume located between the transfer piston 6, 6a and the outer end of the housing 5 communicates with a hot heat exchanger 7 connected to a hot source (not shown) and constitutes the hot chamber or expansion volume V E of the Stirling engine, while the volume located at the other end of this cylindrical housing 5 communicates with a cold exchanger 8 connected to a cold source (not shown), which is the cold room or compression volume V C Stirling engine.
  • a regenerator 9 is disposed between the heat exchanger 7 and cold 8.
  • the internal volume of the cylindrical portion 3 encloses a movable member 14 of an electric generator, here constituted by a cylindrical element carrying permanent magnets.
  • This movable element 14 is integral with the periphery of an annular support 15, whose inner edge is integral with an annular elastic suspension member 16, similar to the member 12.
  • the periphery of this member 12 is fixed to the frame 4 and its center is secured to a rod 17, one end of which is fixed to the transfer piston 6, 6a.
  • the armature of the generator is formed of an assembly of plates 18 arranged radially and in which are housed one or more windings 19 of annular shape.
  • the movable element 14 of the electric generator is surrounded by an armature 20, formed here of an assembly of plates arranged in radial planes.
  • the interior of the piston 10 is hollow, providing a housing 26 serving as a gas reservoir for supplying nozzles 27 opening into the annular slots between the two pistons 6a and 10, respectively between the pistons and the adjacent surfaces of the housing elongated 1, respectively of the wall of the piston 6a.
  • the compartment 26 is fed through a non-return valve 28 from the working volume and maintained permanently at the maximum pressure prevailing in this volume.
  • Compartment 26 can also placed in the transfer piston 6, 6a or in the frame 4, to feed the nozzles 27 of the static gas bearings.
  • the moving part of the electric generator may be provided with a flywheel 34, to balance the rotary movement and thus to smooth the superimposed waves to the generated voltage. Moreover, a mass 35 makes it possible to attenuate the vibrations due to the reciprocating movement of the pistons.
  • the operation of the Stirling machine described is as follows:
  • the movement of the second resonant piston 10 is dictated by the forces communicated by the elastic elements and the gas pressure exerted on its axial surfaces. By its movement, the pressure of the working gas varies.
  • This transfer-motor piston can be designed as a free piston. Its elastic suspension must then be tuned so that the piston oscillates at the same frequency as the resonant piston. Its amplitude is controlled by the forces electric powered by the generator; it remains fixed if a constant electric charge is applied to the terminals of the electric generator.
  • the figure 5 compares the mechanical energy released by a Stirling engine comprising a transfer piston and a working piston, as a function of the temperature T H of the heating tubes (curve 1) with that of an engine according to the invention (curve 2).
  • the hot exchanger In order to start the Stirling machine which is the subject of the invention, the hot exchanger must first be brought to a relatively high temperature T H (for example 600 ° C.), which threshold depends on the ratio a C / a E chosen.
  • the transfer-motor piston 6, 6a is then oscillated using the electric generator associated therewith.
  • the resonant piston 10 first oscillates with a small amplitude, which gradually increases with the heating temperature T H.
  • the amplitude of the working gas pressure also increases, as well as the mechanical power supplied by this machine. The nominal power is reached when the heat exchanger is heated to about 700 ° C.
  • the resonant piston 10 receives at each cycle a small amount of energy which serves to compensate for its friction losses and keep it in oscillating motion.
  • the amplitude of its movement Y determines the pressure variation of the working gas and therefore the engine speed. Fine tuning is possible insofar as piston friction remains relatively constant over time as can be achieved using the aforementioned static gas bearings.
  • the control valve 24 makes it possible to adjust the pressure amplitude of the working gas, and therefore the amplitude of the resonant piston.
  • temperatures T H of the heat exchanger vary only slightly with the engine load is particularly advantageous in units heated with fuel.
  • the operation of a burner depends strongly on the temperature conditions which settle there; complete combustion with a minimum of pollutants can only be achieved if the temperature conditions remain sufficiently stable.
  • the two pistons 10a and 10b are arranged coaxially in a common cylinder disposed laterally to the main axis of the machine.
  • the two external volumes 45a and 45b of the common cylinder are connected to the compression volume V C of the Stirling engine by ducts 29.
  • the central volume 45c can be connected by a duct 44 to a volume 48 exposed to an almost constant mean pressure, through example that of the volume of the electric generator.
  • the central volume 45c can be connected to the cold room V C and the external volumes 45a and 45c to the volume 48.
  • the present invention proposes another system for attenuating the vibrations transmitted to the enclosure of the machine, illustrated by the figure 10 .
  • the additional mass 41 is elastically connected to the transfer piston 6, 6a and to the frame 4 of the machine.
  • the elastic suspensions 42a, b and c are adjusted so that at the operating frequency of the machine, these two masses oscillate in opposite directions with respect to each other, so that the vibratory forces transmitted to the enclosure or frame of the machine are canceled.
  • the vibrations generated by the movement of the pistons are thus reduced at the source.
  • the elastic means 42a, b and c may consist of spiral or flat mechanical springs, electromagnets, pneumatic means or combinations of these various elastic supports.
  • This vibration suppression system effectively compensates for the action of a single oscillator. It is therefore particularly suitable for Stirling machines with opposite resonant masses, since only vibrations generated by the transfer piston must be compensated.
