Abstract

The power device including a supply chamber, supply conduits and gas off takes as well as a rotor characterized in that the supply chamber (3) has in fact a circular shape in a cross-section and in an outlet chamber there is placed a sleeve (5) equipped with at least two ports (6) at the end from the side of rotor, directed to the centre of chamber and located opposite each other, with a circular or elliptic cross-section, however the diameter of supply chamber (3) makes up from 1.01 to 5.00 of rotor diameter (7)

Description

  • 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.
  • In order to increase pressure force on blades as well as the most even distribution on all rotor blades in the interior of supply chamber there is placed a number of steering-wheels or guide blades. The solution of this kind is famous for the invention with the patent no. PL 173382 . The description reports the turbine with a turbocharger, driven with combustion gases and radiating flow, having the row of single shift guide blades, from which each one is rotated by means of shifting roller placed in a casing, however each shifting roller is activated by means of luffing-jib lever. Every two neighbouring luffing-jib levers are coupled by means of connecting element, however 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 essence of solution according to the invention is that 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.
  • It is advantageously, when a sleeve has a flange equipped with at least two ports with a circular section, placed opposite each other.
  • It is advantageously, when a sleeve has a flange equipped with at least four ports with a circular section, placed in pairs opposite each other.
  • It is very advantageously, when a sleeve has a flange equipped with at least a dozen or so ports with a circular section.
  • It is advantageously, when 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.
  • Such construction forms extremely efficient driveline. Homogeneous pressure distribution follows in a chamber with an annular section in its all capacity, and that results in an equal stream of flowing out gas from each hole in a sleeve, what gives an even load of turbine rotor blades. The invention is presented in performance examples in the figure, not restricting at all, on which fig. 1 demonstrates a schematic view of power device in a complex condition, fig. 2 demonstrates a schematic view of power device in a rearranged condition, fig. 3 presents a sleeve with a flange with a lot of circular section holes, fig. 4 presents a sleeve with a flange with four holes of circular section, 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. In an internal sleeve there is placed a flange sleeve 5, equipped with ports 6, directed to turbine blades 7. The flange sleeve is immobilized through a lid clamp 8.
