Definitions

  • Turbines supplied with a pressurized fluid are already known. This is the case, for example, of the turbine represented in the French utility certificate No. 2 370 874 (registration No. 76 35 439) which, supplied with water under pressure, is capable of driving tools, such as brushes for underwater painting.
  • the invention intends to remedy these drawbacks and improve both the overall yield and the conditions of use of such turbines.
  • This turbine comprises means for guiding the pressurized fluid between the intake port and the exhaust ports.
  • the shutter is itself provided with holes 39, 40 which correspond to said first and two orifices, respectively, and which, moreover, according to the position of this shutter relative to the protuberance 8, coincide with certain exhaust orifices. .
  • the two holes 39 are centered on the same diameter of plate 29; one of the holes 40 is centered in the diametrical plane passing through the holes 39; and, the other two holes 40 are centered in a diametral plane angularly offset from the plane of the holes 39 and are, moreover, diametrically opposite.
  • the holes 39 and the hole 40 centered in their diametral plane are arranged opposite the first orifices 37 and one of the second orifices 38, respectively, allowing the fluid to s' escape out of the casing along the axis arrows 37a and an axis arrow 38a.
  • the space between the internal face 3 of the casing and the external face 11 of the injection ring 10 constitutes a chamber 41, known as, for admitting the pressurized fluid into the casing. From this chamber 41, the fluid passes inside the injection ring 10 by passing through injection orifices 42 preferably profiled in venturi. This fluid pushes on the blades 16 of the rotor, causing this rotor to rotate in the direction of arrow F in FIG. 1. Finally, passages 43 provided in the hub 15 of the rotor, between the blades 16, allow the fluid to pass from the external zone to the axial central cavity 17 of the hub in this cavity.
  • the upper surface 48 forms an angle B between 40 and 60 degrees. Furthermore, when the upper surface 48 of the extension 47 intersects the internal face 12 in the area of an injection orifice 42, it is noted that the angle C of the upper surface 48 with the mean axis 50 of this orifice d injection 42 is between 70 and 80 degrees.
  • each blade 16 contributes on the one hand, to obtaining a simple and little realization expensive, but also, on the other hand, to obtain a non-turbulent flow of the fluid as far as the axial cavity 17 of the mold, with high efficiency.
  • the various possibilities provided by the shutter 25 allow easy use of the turbine, and of the tool which it is capable of driving.
  • the exhaust flows 37 and 38 provided for the fluid are particularly direct and therefore cause the smallest possible losses in efficiency.
