Definitions

  • the present invention refers to a system for the construction of pumps, compressors and rotary engine composed of two rotors with one, two or more displacers per rotor, so as to create among the displacers two or more chambers, depending on the quantity of displacers per rotor.
  • the chambers vary in volume according to the degree of separation between the pistons caused by velocities that are varying and alternatively opposite between the two rotors.
  • This variation in speed is produced by a system composed of a double crankshaft and connecting rods for sliding or rotating that work in opposite positions articulating with the arms attached to each of the rotors and at a distance from their geometric axis. This distance allows the variation of the length of the radio in which the movement is broadcast, thus transforming a continuous movement of the double crankshaft in a varied movement of acceleration and deceleration in the rotors with their displacers or vice- versa.
  • the new system is characterized by the fact that the displaced volume can be varied, altering the distance between the geometric axes from the double crankshaft that articulates this oscillating movement of varied speed and the geometric axis of the arms attached to the rotors with their respective displacement.
  • the double crankshaft or the positive displacement machine By placing the double crankshaft or the positive displacement machine on a chute or on sliding axes and change by means of a spindle the distances between the geometric axes, there is also a change of the degree of maximum and minimum distance between the displacers, thus changing the volume displaced.
  • This displaced volume change can be modified with the system in movement or static.
  • This spindle can be manual or mechanical through a suitable electric motor, which obeys a computerized program with pre-established answers, maintained by readings of temperature sensors, speed, torque, burning quality, etc. and other supplied information.
  • a suitable electric motor which obeys a computerized program with pre-established answers, maintained by readings of temperature sensors, speed, torque, burning quality, etc. and other supplied information.
  • This way the compression rate of an engine, or a compressor, for example:, could be modified during their operation, optimizing their performance.
  • this invention also proposes a mechanism that permits a variation of the relative position between the fixed part of the chambers where there are the intake and exhaust ports, spark plugs, valves, etc. of the rotors with their respective displacers.
  • This change in position can be done by moving in a sliding manner the fixed parts of the chamber where the intake, exhaust ports etc. are placed around the geometric axis of the rotors through the gearing (see Figure 2) of a spindle attached to an arm, for example.
  • Another possibility is moving the angular distance between the geometric axis of the double crankshaft around the geometric axis of the rotors, thereby changing the relative position between the fixed part of the chamber and the rotors with their displacers (see Figure 6).
  • This option offers the possibility to increase the rate of displacement with the opening time of the suction in relation to the speed of the system.
  • This displacement can be done through a manual mechanism or moved by a step engine, controlled by a computerized program, up to the desired position, according to readings of sensors of speed, torque, temperature, etc.
  • the new system is characterized by replacing the attached arms directly to the rotors by a pair of larger gears that mate with another pair of smaller gears attached to the arms.
  • the gears attached to the arms connect themselves in opposite positions with the double crankshaft through sliding or rotating rods, and thus allow the movement at varying and alternatively opposite speed of both rotors with their displacers.
  • the size of the gear and the number of teeth should be proportional to the amount of displacers that supports each rotor. Operating a reduction to half when there are two displacers per rotor, a third for three displacers per rotor, a quarter for four displacers, and so on.
  • the double crankshaft with its articulated or sliding connecting rods working at a distance from the geometric axis of the rotors produce at each 180° a cycle of acceleration and deceleration of these rotors.
  • this innovation proposes a geared system of reduction that transforms the cycle of acceleration and deceleration caused by the removal of the geometric axes at each 180° by means of reduction gear from 2 to 1 in 4 cycles, where, for example, a rotor will run through 45° and the other 135° and in the other 180°, already gone through by the crankshaft, will reverse the set of movement of rotors and that rotor which moved 45° will run over 135° and the other 45 ° ( Figure 5).
  • the alternative piston or rotary eccentric engines as the Wankel engine, work with a fixed compression rate determined to prevent pre-detonation, which is why they work with lower rates of compression to prevent pre-detonation in low-speed, so that even in low rotation the dreaded pre-detonation will not be produced.
  • the variation of compression rate while the engine is functioning at different revolutions per minute, taking into account the operating temperature, etc. will permit a better use of different fuels without the risk of pre- detonations.
  • This invention allows the modification of the compression rate and the positioning of the intake and exhaust ports optimizing its volumetric efficiency according to parameters of speed, torque and temperature, providing better combustion of fuels, which means lower levels of pollution and more energetic use.
  • crankshaft with sliding or rotating rod were designed to work with fixed distances between the geometric axes, with prefixed compression rates.
  • the displacers can only be moved without collisions separating the axis of the rotor from the crankshaft to create such an eccentricity that at the displacement of 180° of the crankshaft, it makes the first rotor with its respective displacers 1 and 1 ' run through and an angle of 225° and the other one with its displacers 2 and T go through an angle of 135° so producing a first approach between the four displacers 1 and 2 and 1' and 2'.
  • the new system proposes using a reduction geared with 2-1 in the case of 4 pistons, so that when the double crankshaft run through 180° and this movement become a movement via rods of 270° and 90° in each of the rotors, the movement is reduced by the gear attached to the rotors and the arms at the displacements of 135° and 45°, respectively, for each of the rotors. See figures 5a-5b.
  • this invention provides a system for the construction of pumps, compressors and rotary engine composed of two rotors with one, two or more displacers each, which move in the same direction at speeds that are varying and alternately opposite one another, using a system of double crankshaft with connecting rods or sliding and rotating rods, characterized by the fact that the displaced volume rate can be modified changing the distance between the geometric axis of the arms attached to the rotors and the geometric axis of the double crankshaft.
  • the rotors when they support two displacers each, they should be attached each to bigger gears related to other smaller gears, half the diameter of the first, each attached to arms that connect at opposite positions with the double crankshaft through sliding rods or rotating rods.
  • the proportion of reduction between gears depends on the amount of displacers that each rotor supports, being a third of the diameter for three displacers per rotor, a quarter for four displacers per rotor and so on.
  • the double crankshaft or the set of rotors and arms are fixed on rails or sliding axes and can be mechanically moved changing the distance between their geometric axes by means of a spindle, so as to vary the distance between the displacers thereby changing the displaced volume or the compression rate of the two sets of pistons in a gradual manner whether the system is static or moving.
  • the relative position between the rotors and their displacers with the fixed parts of the chamber where there are the exhaust and intake ports, sparkplugs, etc. can be modified changing the angular distance of the fixed part of the chamber, in relation to the geometric axis of the rotors and their respective arms and vice versa.
  • this change is done by moving the fixed part of the chamber by means of a spindle or by gearing, changing the angular distance in relation to the geometric axis of the rotors, thereby changing the relative position between the fixed part of chamber and the rotors with their displacements.
  • this modification may be done putting the bearings that support the double crankshaft on sliding rails and using a spindle system that allows changing in a sliding manner the angular distance between them.
  • the relative position between the rotors and their displacers with the fixed parts of the chamber where there are the exhaust and intake ports, sparkplugs, etc. can be modified together with the compression rate putting the bearings in a sliding manner on rails from a inclined plane to move it by means of a spindle so as to change in the right measure the compression rate together with the relative position of the ports in relation to the displacers.

Abstract

Le nouveau système selon l'invention est caractérisé en ce qu'il permet de faire varier le volume déplacé et la position relative du port d'entrée (31), du port de sortie (30), des bougies etc. par rapport aux dispositifs de déplacement (1,1 ' et 3,3), par modification de la distance angulaire et linéaire séparant les axes géométriques du double vilebrequin (11), ce qui permet d'obtenir un mouvement oscillant à vitesse variable, et les axes géométriques des bras (6,7) fixés au rotor au moyen de leur dispositif de déplacement respectif. Le fait de placer le double vilebrequin (11) ou la machine à déplacement direct sur une goulotte (13) ou sur des axes de glissement, et de modifier, au moyen d'une broche (14), les distances entre les axes géométriques, provoque la modification du niveau de distance maximale et minimale parmi les dispositifs de déplacement. Le fait de modifier la distance angulaire entre les parties fixes de la chambre et le double vilebrequin provoque la modification de la position du port d'entrée et du port de sortie, cette modification peut s'opérer lorsque le système est fixe ou en mouvement, de manière manuelle ou informatique.
