Definitions

  • the subject of invention is a power device, especially of blade turbines, particularly useful for turbo-compressors designed for motor vehicles with self-ignition, for devices balancing all kinds of machine, device and vehicle rotators, and also for pneumatic tools.
  • Well-known power devices in which gases are the power factor, have a worm-shaped chamber with a rotor equipped with blades.
  • Gas supply is realized by the pipe placed tangentially and its release by the pipe centrally located in relation to the rotor axle.
  • Through decreasing diameter of supply chamber as going away from an inlet pipe, one can obtain mildly even pressure of gas particles on rotor blades on its whole periphery.
  • the fundamental difficulty is appropriate designing of worm curvature as to obtain optimally even pressure on all rotor blades for occurring range of power gas pressures.
  • connecting elements have a rotation axis in their mounting points with a luffing-jib lever, while the space between rotation axes of connecting element corresponds with the space between two neighbouring shifting rollers.
  • the solution according to this invention guarantees that all luffing-jib levers do the same angular travel, but it has to be kept a lot of accomplishment precision of moving elements in order not to occur mechanism binding during utilization as a result of thermal expansion induced by hot combustion gases.
  • the solution according to the invention described below eliminates these inconveniences.
  • the supply chamber has got in a cross-section a circular shape in fact, and in an outlet chamber there is placed a sleeve equipped with at least two ports at the end from the rotor side, directed to the centre of chamber and located opposite each other, with a circular cross-section or elliptic section, however the diameter of supply chamber makes up from 1.01 to 5.00 of rotor diameter.
  • a sleeve has a flange equipped with at least two ports with a circular section, placed opposite each other.
  • a sleeve has a flange equipped with at least four ports with a circular section, placed in pairs opposite each other.
  • a sleeve has a flange equipped with at least a dozen or so ports with a circular section.
  • a sleeve has a flange equipped with at least two ports with an elliptic section, placed opposite each other, which elongated axis is tangential to the rotor periphery. It is advantageously, when a sleeve has a flange equipped with at least four ports with an elliptic section, placed in pairs opposite each other, which elongated axis is tangential to the rotor periphery. It is very advantageously, when a sleeve has a flange equipped with at least a dozen or so ports with an elliptic section, which elongated axis is tangential to the rotor periphery.
  • FIG. 5 demonstrates the view of sleeve with a flange with two holes of circular section
  • fig. 6 presents a sleeve with a flange with a lot of elliptic cross-section holes
  • fig. 7 presents a sleeve with a flange with four holes of elliptic cross-section
  • a fig. 8 presents a sleeve with a flange with two holes of elliptic cross-section.
  • the driving device has got a body 1 with a central sleeve 2 and a supply chamber 3 in a ring shape formed in this way, equipped with a power cable 4A and piping away outlet pipe 4B centrally placed 4B.
  • a flange sleeve 5 equipped with ports 6, directed to turbine blades 7.
  • the flange sleeve is immobilized through a lid clamp 8.
