Definitions

  • Subject of the design is a machine with a rotating rotor fuelled by a pneumatic medium, acting as an engine, turbine or pump and used for powering household appliances, industrial or transportation devices.
  • Machines, engines, turbines and other devices using flat, rotary core are already common and are used for power supply of household appliances, industrial or transportation devices.
  • the well-known engines with a rotary core in a shape close to triangular, with slightly flattened edges were equipped with a body with an elliptic-shaped chamber, inside of which the piston rotated eccentrically around an axis of a drive shaft. This movement was realized by a geared connection placed inside of the piston, and outside the drive shaft.
  • Other solution, used in German patent and known in Poland as the patent number 61652 is the use of lining in internal engine chamber with a flat rotating piston, which is improving the engine's durability/reliability factor.
  • German patented solution number 59513 a thermal insulation of a triangular-shaped, rotating piston's layer is implicated for the purpose of increasing the lifetime.
  • Other engines with rotating piston, cylindrical body and rotor in a shape close to elliptical or circular, are also known.
  • Polish patent 76238 describes an engine with an elliptical-shaped piston rotating inside of a cylindrical-shaped body. The described piston has four channels - two of them are inlet channels and the remaining two are outlet channels - and four moveable surfaces of the combustion chambers, which are controlled with the use of pushers.
  • Polish patent specification number 94611 A cylindrical body and eccentrically rotating rotor is equipped with four symmetrically placed turbine vanes, which position is changed centrifugally.
  • inflow and outflow compressed air channels inside of the body, placed tangentially to the rotor chamber. Between the rotor blades the cut-outs are located asymmetrically and shifted away from symmetry plane in the direction opposite to the rotor movement.
  • vane rotor of pneumatic engine is placed on a shaft, concentrically to the body's main chamber. This invention is equipped with the inflow and outflow channels with nozzles inclined with regard to the rotor vanes.
  • a tri-vertex rotor placed eccentrically on a shaft moves in elliptic body chamber, and the rotor's shaft is equipped with an axial channel, that converts into a radial channel, together with a counterweight.
  • the hereby invented rotary machine is built of a cylindrically-shaped body with two separate covers and a rotor coaxially fixed on a shaft, sealed together in a collective body.
  • the aim of sealing the system is to prevent the fluid from unexpected leaking.
  • the rotor is cylindrically shaped and it has three splines placed on the apexes of an equilateral triangle. Those splines are involutedly shaped and are sealed in the body's main chamber. Inside of the body, some inflow and outflow boreholes are drilled to enable the flow of pneumatic medium. Those holes are placed on the bottom board of the body, symmetrically and are alternating one another.
  • the sealing discs have circumferential cut-outs with shape corresponding to involutes of the splines on the rotor accordingly.
  • the pneumatic medium pressured into the chamber through nozzles, causes the pressure in a chamber between cylindrical body and the rotor, to increase. The increased pressure then acts onto the splines, causing the rotor to move until the outflow nozzle is revealed by these splines.
  • the machine with rotary rotor according to the invention's description, is shown as an exemplary model on a separate drawing, where fig. 1 shows the cross-section of the machine.
  • the machine with a rotary rotor had been exemplary built with a cylindrical body (3), together with covers and concentric to the rotor (1) sealed in the body (3).
  • the rotor (1) has a cylindrical shape and three splines (2) shaping the corners of an equilateral triangle. Those splines have involute-based shapes and are sealed in the body's main chamber (3).
  • some inflow nozzle holes (4) and outflow nozzle holes (5) for the pneumatic medium are drilled, and are placed symmetrically, and alternating one another, on the bottom board of the body (3). Between the inflow (4) and outflow (5) nozzle, the rotating sealing discs (6) are symmetrically placed.
  • the rotational speed of those sealing discs is synchronized with the rotational speed of the main machine shaft placed inside of the rotor (1), but their directions are contrary.
  • the sealing discs (6) have circumferential cut-outs, which shape is adequate to the shape of the splines on the rotor (1), as it had been described.
  • the pneumatic gaseous medium forced through the inflow nozzle (4) causes the pressure inside of the chamber between the body (3) and the rotor (1) to rise, henceforth acting with force onto the splines (2) of the rotor (1). This phenomenon causes the rotor to rotate until the moment, in which the outflow nozzle (5) is revealed by the rotor's splines (2). This cycle is then being repeated with the use of a second pair of nozzles.
  • the cylindrical rotor might have an increased number of splines, placed on the apexes of some figures with shapes close to other regular figures, provided that the number of inflow and outflow nozzles should be adequate to the number of splines.
