Definitions

  • the present invention relates to a fluid accelerator device for a central water heating circuit.
  • the simplest known circulators are driven by an electric motor. As a result, the problem of possible local overheating becomes particularly crucial in the event of a power failure.
  • thermosyphon in any heating system supplied by a wood or coal boiler.
  • a heat recovery unit installed in an open fire, mounting in a thermosyphon is very often impossible.
  • the recuperator is generally at the same height as the radiators, so that a thermosyphon installation is hardly possible.
  • German patent No 457 674 describes a fluid accelerator device, comprising an accelerator member mounted in a circuit of a first fluid, an electric motor coupled to said accelerator member, a drive turbine powered by a second pressurized fluid and also coupled to said accelerator member, and a valve mounted on the second fluid supply circuit of the turbine and automatically controlled to start the drive turbine in the event of the power supply to the electric motor stopping, said valve being coupled to an electro -magnet.
  • the present invention proposes to overcome the various drawbacks mentioned above and proposes to ensure the permanent operation of an accelerator whose autonomy is unlimited, the reduced size and the relatively modest cost.
  • the simple design of the proposed device guarantees almost total reliability and zero maintenance.
  • the accelerator device as mentioned above, is characterized in that the circuit of the first fluid is a domestic central heating circuit, that the second fluid is water and in that the electromagnet and the valve are arranged so as to also close the supply circuit for the second pressurized fluid in the event of restoration of the supply current to the electric motor.
  • the accelerator, the electric motor and the turbine are mounted in respective adjacent watertight housings.
  • the turbine 1, mounted in a housing 10, is intended to be driven in rotation about its central axis 6 when a jet of pressurized water 5 is projected onto its blades by the injector 2.
  • a electromagnetic valve 4 opens or closes the circuit connecting the water pipe 5 to the injector 2.
  • the housing 10 of the turbine is secured to the carcass of an electric motor 7, the axis 6 of which is connected to the both to the turbine 1 and to the accelerator 8, these two members being arranged on either side of the carcass 7 of the engine.
  • the electric motor 7 supplied with current drives the accelerator 8 which is in charge, since it is mounted on a conventional circuit 9 of central heating, or on the part of the circuit in which is incorporated a heat recovery unit placed in an open fireplace.
  • the electric motor also drives the turbine 1 which rotates when empty.
  • the electromagnetic valve 4 pre-armed by means of a spring (not shown), opens the water supply 5 of the injector 2, and generates the rotation of the turbine 1, which takes over from the electric motor 7 to rotate the accelerator 8.
  • the water projected by the injector 2 on the blades of the turbine 1 is discharged through the conduit 3.
  • the accelerator 8 is driven either by an electric motor 7 or by the turbine 1, and the transition from the first to the second drive mode takes place automatically in the event of a cut, even accidental, of the electric current supply to the motor 7.
