Definitions

  • the variable volumes may rotate in one or two directions, like the transmission shaft.
  • the transmission shaft may rotate more or less than 2 ⁇ : when it is more than 2 ⁇ , this machine is of rotating cyclic volume type; when rotation is less than 2st, it is of alternate cyclic volume type.
  • the cyclic volume machine as a rotating type, because the alternate function does not change the characteristic of the original geometric discovery which lies at the base of this invention.
  • many rotating machines with inner variable volumes have been invented, but they all have problems, as for example the Wankel engine, whose inner wall contour, in cross-section obtained by means of a perpendicular plane to the longitudinal machine axis, is a trochoid curve.
  • the main problem of the Wankel engine is insufficient compression at low speed of rotation and consequent irregular combustion.
  • the angles of the Wankel rotor have no suitable contact with the trochoid surface, and neither they nor the springs last long.
  • the inner stator surface of this new machine is the envelope of a rotating solid whose rotation axis runs perpendicularly to a plane in the points which are those of a plane curve with a new invariance length.
  • This curve may be machine-tooled and drawn with continuity by means of continuous lines.
  • the present invention is composed of a stator body with an inner cavity containing a hinged prismatic rotating structure called a rotor. Between the stator and the rotor are variable volumes defined by chambers. The interior of the rotor also has one chamber of variable volume. The volumetric yield is higher than in the Wankel engine. The sides of the prismatic structure work with external and internal walls.
  • the transmission shaft connected to the rotor is supported by stator bases which always touch the rotor and stator body.
  • the cyclic volume machine may be made in many shapes and used for many purposes: it can work as a pump, compressor, motor, engine, valve, distributor, or hydraulic joint; it may burn fuel for heat and/or electricity as in magneto-hydrodynamic generators ; it can also be used as a compressor and/or booster for thermic motors with inner reactive combustion.
  • FIG. 1 and Figure 2 show two views, erection side and plan, by means of orthogonal projections, of a rotating cyclic volume machine with a four-sided rotor;
  • FIG. 3 shows the same stator of the rotating cyclic volume machine shown in Figure 1 and Figure 2 with another type of rotor composed of cylindrical sides:
  • FIG. 4 shows a rotating cyclic volume machine stator body and its six-sided rotor made by packing multiple thin sheets
  • FIG. 5 shows the scheme of a type of rotating cyclic volume machine used as a two-stroke engine.
  • Stator body 1 has an inner cavity defined by a wall with contour 2.
  • longitudinal axis Y of contour 2 is the longitudinal axis of the machine.
  • Y is perpendicular to the plane used to draw the section of the machine,
  • C is the point of intersection between centre line Y and the plane.
  • the motion of the machine's rotating parts are referred to the stator fixed to P .
  • N 4 P 1 constant length, each composed of one solid or piston 5 between two hinges which, in this case, are cylinders 4.
  • the rotor is inside 1 and touches 2 by interposed adaptable rings 10 between 2 and 4 and/or between 4, 5 (not shown) and stator bases or flanges 16.
  • Inextensible connection or bar 7 joins two pistons 5 reciprocally opposite by pivots 6.
  • Rotor side length (W) lies between two of the consecutive axes 4.
  • Pieces 4, 5, and 10 are in this case geometrical right- angled solids or pistons of equal height.
  • stator bases 16 Their flat bases are parallel to , and slip against flat inner surface 17 of stator bases 16.
  • the stator is composed of 16 together with 1.
  • Stator bases 16 hold transmission shaft 14 by bearings (not shown).
  • Lubricant inlet and outlet are 15, and 3, 12 respectively, passing through 14, 7, 6, 5 and 4 among the touching parts to create a fluid film.
  • each chamber On each rotor side is one rotating chamber, in this case four, each chamber retaining variable volume V ( ⁇ ) .
  • Volumes V ( ⁇ ) vary N times/revs corresponding to (N 2 /2 cycles/revs).
  • At the back of (N) rotating sides ) of the rotor is one chamber Z, whose volume (Z ( ⁇ ) ) varies (2N times/revs) corresponding to (N cycles/revs).
  • the valves in 3 are optionals, but may be necessary according to machine function.
  • rings 10 may not be necessary, according to machine function.
  • the four chambers with variable volume V ( ⁇ ) limited by rotating surfaces 9, two rings 10, stator contour 2 and two flanges 16, are defined for any value of ( ⁇ ) and retain one or two fluids in this case, or more than two fluids depending on the (N/2) number of chambers.
  • the cyclic volume machine transforms the movements of fluid/s in chambers V and/or chamber Z into rotation of transmission shaft 14: on the contrary, it may transform transmission shaft rotation into movements of fluid/s in chambers V and Z.
  • the fluid in chamber Z is the same used for the cooling and/or lubricating systems of the machine; it can load a hydraulic accumulator and/or drive other alternate and/or rotating tools.
  • wall 9 is a cylindrical surface.
  • the rotor can be made by packing thin metallic sheets 20 and 21 as in Figure 4. it may also be an open prismatic structure, and composed of only one side without hinges, or composed of solid cylinders only.
  • Figure 3 is the model of a pump for liquids, whose transmission shaft is connected to cylinders 4, sliding on cross-bar 22.
  • F - P a , constant, we transform: [ l h ] ⁇ [R N ]
  • ⁇ N ( ⁇ ) ⁇ a 2 - f 2 ( ⁇ ) , 0 ⁇ ⁇ ⁇ 2 ⁇ (1)
  • the shape of the cross- section of the stator inner wall of a cyclic volume machine may be a mixed line; in this case, the rotor may travel less than (2 ⁇ ) and the result is an alternate cyclic volume machine and/or a rotating cyclic volume machine with inner interconnected chambers: in this case the sides of the rotor may not be all equal.
  • the rotating cyclic volume machine in Figure 1 and Figure 2 may also be a two-stroke engine. It is presumed that: channels 3, 12 and 19 are eliminated, four channels bored in each slipper piston are controlled by one-way valves; where stator inner wall 2 is at its maximum curvature, two exhaust channels are placed (not shown). The combustible mixture is precompressed in Z and, through the four piston channels, enters chambers V. When the pistons are in. 11 ignitions occur, the expansion of gases moves the rotor, and waste gases are discharged through the exhaust channels.
  • the axis of the inner cavity of the stator body cannot coincide with the axis of the cyclic volume machine and/or the machine axis cannot coincide with the rotation axis. All longitudinal axes must, always be parallel to them. Channels for fluids, controlled by valves according to machine function, can also be inserted in the transmission shaft and rotor sides. Rotating cyclic volume machines may be connected to only one virtual or real rotation axis, giving compound rotating cyclic volume machines with their V and Z chambers all directly or indirectly connected to the transfer channel/s by the same rotors or otherwise controlled.
  • Figure 5 shows a schematic view, by means of orthogonal projections, of a coaxial cyclic volume machine or compound machine, composed of one rotating compressor cyclic volume machine and one rotating engine cyclic volume machine with only one transmission shaft 14 and one common stator flange between them.
  • Operating fluid enters 3 and, through the two transfer channels 23 bored in common flange 26 controlled by engine rotor P 1 P 2 P 3 P 4 , passes to the two opposite chambers sending waste gases through exhaust channels 24 bored in the stator flange of the engine side.
  • Maximum fluid compression occurs in engine area 25, where ignition takes place and expansion of gases rotates the polygonal structure of the engine and compressor.
  • cooling fluid enters the Z area of the compressor, passing through the Z area of the engine, and loads a hydraulic accumulator which is also a heat radiator (not shown).
  • Transversal axes X 1 and X 2 form angle ⁇ on the projection plane.
  • Angle ⁇ is important for correct precompression of the engine.
  • the cyclic volume machine may be modified or varied in many ways without changing its peculiar geometry which is the basis of the invention, i.e., the geometrical discovery of invariance length (W) which is a geometric property of many mathematical functions. Only when trajectory (R N ) with invariance (W) are defined, can machine tools or tools be programmed.
  • V ( ⁇ ) and Z ( ⁇ ) volume variations can be planned according to desired phenomena to obtain the thermodynamic cycles suitable for various functions.
  • suitable segments 10 and/or abrasive oils By the liddition of suitable segments 10 and/or abrasive oils, the same cyclic volume machine rotor can be used as a tool to rectify inner stator surface 2, which is the envelope of external surface of rings 10 rotating and/or oscillating round ( R N )points and pole C.
  • the surface of 10 touching 2 need not be cylindrical, and can be radiused to the internal surface of the stator bases.
  • the inner stator wall contour may have only one symmetry axis.

Abstract

Machine rotative avec volumes variables pouvant tourner dans un et/ou deux sens, tel qu'un arbre de transmission plus ou moins que (2pi). La machine est composée d'un boîtier avec une cavité intérieure qui contient une structure rotative articulée prismatique composée d'un ou de plusieurs côtés. Entre la cavité intérieure et les côtés de la structure prismatique, et le long de ces mêmes côtés dans la zone intérieure, se trouvent des chambres à volume variable de rétention de fluides. La machine à volume cyclique exploite les variations des caractéristiques physiques de fluides dont les mouvements sont la cause ou l'effet de la rotation de l'arbre de transmission. Des forces centripètes s'opposent à des forces centrifuges au niveau de barres transversales et/ou de charnières appropriées situées entre les côtés du rotor. Des systèmes de lubrification et de refroidissement sont également prévus. La machine à volume cyclique peut avoir le même axe qu'un arbre de transmission commun et peut être utilisée comme pompe, compresseur, moteur, soupape, distributeur, accouplement hydraulique, et générateur de chaleur. Elle peut également alimenter un générateur électrique magnétohydrodynamique, et servir de compresseur ou de dispositif de renfort pour moteurs à combustion réactive interne.
