Definitions

  • the invention herein refers to a system consisting of two or more rotors with at least one piston on each moving at varying and alternatively opposite velocities to each other inside a cylindrical chamber, either independent or formed by the rotors themselves.
  • the volume of the chambers will vary according to the relative velocity of the rotors in relation to each other, thereby enabling aspiration, compression of fluids in the case of a compressor, or the four basic operations of any internal combustion engine (suction, compression, explosion, expulsion).
  • This system also permits the building of motors that operate by heating a fluid inside and its later cooling and compression or using the pressure of any kind of fluid.
  • This new mechanism does not require the use of valves since the same pistons in their trajectory alternatively open and close the openings of the cylindrical chamber when they move.
  • the movement of two or more rotors at varying and alternatively opposite velocities to each other can be obtained by different types of eccentric mechanisms or through an alternate variation of a diameter of gear segments or varying through electronic media at a velocity of two electric motors. Basically they can be divided in four types of systems, as follows:
  • the first system for transforming a continuous circular movement of an axis in an alternately varying and opposite movement of velocities of the axes to each other and vice versa characterized by the fact that: the center of the moving axis is separate from the center of the other two axes; the pair of axes and the moving axis are connected to brackets; at least one pair of these brackets has fixed points from where it transmits the movement and the other pair has a shape that is suitable for fixed transmission points to slide along their length; the fixed points of movement are forced to move along the radius length of the other brackets, thereby varying the length of the movement-transmitting bracket, and thus varying the velocity and transforming a movement of continuous velocity into a movement of varying velocity; and the brackets are placed counter to each other so that alternatively when a larger movement is transmitted to one then a smaller movement is transmitted to the other.
  • a second driving system characterized by the fact that eccentric gears are used connected to each of the independent rotors operating in gear through belts or chains to two other also eccentric gears joined to another axis and placed in opposite positions so that, as the gears are off-center and placed in opposite positions, depending on the intersection point between them, the quantity of movement transmitted or received varies. This produces a movement of varying velocity in an alternate and opposite manner.
  • the eccentric gears can have an elliptical shape that facilitates their coupling or transmits their movement through chains or belts.
  • a third driving system characterized by the fact of comprising the use of at least one gear linked to each rotor, each consisting of at least two segments of a circumference arc, one with a larger and the other with a smaller diameter, which relate alternatively to two other gears also formed by at least two segments of a circumference arc (larger and smaller), which operate joined to another axis in opposite positions, so that they alternatively transmit a movement at greater or lesser velocity, in an alternate and opposite form, depending on the pair of gear segments relating to each other.
  • a fourth driving system characterized by the use of at least two electric motors that operate joined to each rotor at varying and alternatively opposite velocities commanded by an electronic circuit.
  • compressor pumps that can be basically divided into two major groups: the alternative pumps that use pistons and a system of rods to move it; and the rotary pumps where most are by eccentric movements with fixed or mobile blades.
  • the invention herein substitutes the eccentric movement for a concentric movement of the rotors, thus guaranteeing perfect tightness of the chambers while maintaining all the advantages offered by the circular pumps.
  • the compressor or motor systems are known to be formed by two rotors, most of which, through some mechanism, hold one of the rotors while the other moves and then the one that is held is released and the one in movement is held.
  • the invention herein does not require this kind of alternating stop and go movement of the rotors and proposes a continuous movement of the rotors at velocities varying in alternate form, thus preventing friction and loss of power and vibrations produced by the other systems. These characteristics undoubtedly permit an increase in velocity of the device, thus increasing its output.
  • Through the invention herein it will be possible to build motors operating in a similar way to the Stirling system by heating, cooling and compression of fluids or motors driven by fluid pressure.
  • the pressure originating from the expansion of the gases will occur on the two pistons, one starting a fast and the other a slow movement.
  • the force will be counter to the direction of the movement.
  • the moving axis will receive two forces through the gears, one of them in the opposite direction to the movement, but the force in the direction of the movement will be greater because it will be transmitted from a smaller to a larger gear, being contrary to a gear with a larger diameter to one with a smaller diameter in the case of the piston that starts moving slowly. This imbalance will drive the moving axis in the desired direction.

  • Other sealing elements 20 run between the two rotors.
  • Seal elements 19 run between the rotors 2 and 3 and chamber 1.

  • Brackets 22 and 23 work joined to these axes respectively, both having two fixed elements 24 and 25 that move freely in part 26.
  • a U-shaped piece is joined to the driving axis 14, the center of this axis is displaced from the center of axes 8 and 9 so that the radius length from where the movement is transmitted may vary.
  • Figure 2 shows a side view of the driving mechanism where the dotted line 28 shows the trajectory of the U-shaped piece 26.
  • the dotted line 29 describes the trajectory of the brackets 22 and 23 with their respective driving parts 24 and 25.

  • the pistons are also seen to open and close the suction and compression openings, without requiring to use valves.
  • Figure 5 shows a side view diagram of a second way for the rotors to move through eccentric gears with an elliptical shape, where the driving effect is similar to that described in figures 4A to 4D.

  • gear 34 joined to the axis 14 and to gear 35 placed opposite to the former, both fixed to axis 14 working in gear with gear 33 joined to axis 9.
  • axis 14 moves, varied and alternatively opposing velocities will occur on axes 8 and 9, respectively.
  • the same effect but with sharp variations in velocity will be achieved using the third system in gear shown in figure 6A-6B where a side view shows the pairs of gears conformed by two segments of a circumference arc in opposite positions.

  • Two rotors 2 and 3 move in a cylindrical chamber 1, each having two pistons 4 and 5 (in rotor 2) and 6 and 7 (in rotor 3) that each run against the other rotor and the chamber so that they share it in four compartments.
  • Each rotor is joined to an axis 8 and 9 respectively, and a pair of gears of different sizes 10 and 11 (on the axis 8) and another pair 12 and 13 (on axis 9) work joined to them.
  • Such gears are built with two circumference segments of equal radius placed in diametrically opposite positions.
  • Gears 10 and 12 have the same diameter, in the example, 3/8 of a circumference, while gears 11 and 13 have 1/8 of a circumference arc.
  • Two pairs of gears 15-16 and 17-18 are fixed on the axis 14, and describe, like the former, two 1/4 circumference radii each placed in diametrically opposite positions.
  • Gears 15-16 and 17-18 are related to gears
  • gears 15 and 17 have a 1-3 larger diameter than that of 10 and 12 and gears 16 and 18, in their turn, have half the diameter of gears 11 and 13.
  • Both rotors move alternatively at two different velocities, one fast and the other slow, describing in each turn two large fast and two smaller slow movements in an alternate and opposite manner.
  • This variation in alternate and opposite velocity of the rotors forces an also alternate modification of the volume of the four chambers formed between the four pistons, thereby permitting suction, compression, explosion and expulsion operations.
  • Openings formed in the cylindrical chamber will permit the admission 30 of air and fuel and expulsion 31 of fluids, closing or opening according to the movement of the pistons.
  • An ignition system placed at point 32 will ignite the mixture.
