Definitions

  • the invention relates to an engine comprising at least one piston with reciprocating linear transmission movement in a combustion chamber and a swash plate mounted at an angle on a shaft driven in rotation in the casing or the engine block by the reciprocating movements of said plate. contact with said piston, the latter being integral with a piston rod whose end situated opposite the piston and comprising a slide guided in a slide forming part of the engine block and whose geometric axis coincides with that of the aforementioned connecting rod, the aforementioned slide trapping two shells constituting a housing for a ball joint connected by a neck to the aforementioned swash plate and extending laterally relative to said swash plate, means being provided for varying the volume of said combustion chamber.
  • the invention aims to allow automatic adjustment of the ratio between the compression ratio and the number of revolutions of the shaft mentioned in the preamble.
  • the aforementioned flywheel consists of two elements, one of which is fixed on said shaft and the other can slide axially thereon, defining between them said volumetric volumetric chamber, so that the element mobile which abuts against the aforementioned swash plate can move it to vary the volume of the combustion chamber remaining between two pistons with opposite translational movement.
  • the engine according to the invention comprises, in its embodiment according to Figure 1, an engine block in which move, two by two and in opposition, cylinders 2 ', 2 "and 3', 3".
  • Inlet lights have been represented schematically by the references 6 and 7.
  • the references 4 and 5 relate to the exhaust lights of the cylinders in which the pistons 2 'and 2 "and 3" and 3 "move. Lights 4 and 5 lead to a common collector. Lights 6 and 7 open onto a common manifold per cylinder.
  • FIG. 1 relates to a type of engine in which two cylinders in opposition are provided twice but that, in other variants to which it will be alluded to later, the engine may have four times two cylinders.
  • each piston is rigidly connected to a connecting rod 10.
  • the mounting elements of this connecting rod and of the slide which is associated with it make in particular the object of Figure 2 in which an exploded view of the cylinder 2 'and the elements with which cooperate its guide members is shown.
  • the connecting rod 10 is connected to a slide 11 having a central housing offering two parallel walls 12 terminated by a cover 13 which is tightened on the slide 11 using four screws 14 which pass through four orifices 15 and are screwed in plate 13 '.
  • the slider 11 is guided in a cylinder 16 which can, in practice, constitute a cylindrical cavity of the engine block but which has, in any case, a first slot 17 whose width is sufficient to allow the movements of the swash plate.
  • the width of the housing between the faces 12 of the slide is equal if not slightly greater than the width between parallel faces of the shells 18 intended to trap, two by two, a ball joint 19 of the swash plate shown diagrammatically under the reference 20.
  • the oscillating movement of the plate takes place in a single plane passing through the plane of symmetry of the housing and therefore also through the geometric axis of the connecting rod 10.
  • the shells 18 - 18 ', trapping the ball joint 19, slide without play along the faces 12' of the abovementioned housing.
  • a pin 23 ( Figure 4) equipped with a roller 24 trapped between guide profiles 25.
  • the purpose of the guide profiles 25 between which the roller 24 circulates is to prevent the rotation, about its geometric axis, of the swash plate 20.
  • the rotation of a piston, in this case the piston 2 ′ of FIG. 2 is prevented by the presence on the cover 13 of the slide 11 of a pin 26 with a roller 27, trapped between the opposite faces of the longitudinal slot 28, provided in the cylinder 16, opposite the wide slot 17. It should be noted that no lateral force is exerted either on the slide or on the connecting rod.
  • the swash plate 20 is wedged on a shaft 29 mounted in a ball bearing 30.
  • the second inclined plate constituted by the lower plate represented in section in FIG. 1 under the general reference 20 ′ is mounted on the same axis but according to an assembly which prevents its rotation relative to the axis but not to a certain longitudinal sliding .
  • Such an assembly is achieved by the presence of an edge 31 provided on the shaft 29 to cooperate with a recess of the elements constituting the swash plate 20 '.
  • This plate which consists of the same elements as the swash plate 20, will be described in detail below and constitutes an essential element of the invention.
  • the motor axis 29 is, opposite the ball bearing 30, mounted by means of a plain bearing 32 in the opposite face of the motor unit 1.
  • This end of the shaft 29 is equipped with a flywheel bearing the general reference 33, consisting of two coaxial elements 34 and 35.
  • the element 34 fixed on the shaft 29 has a circular groove 36 for the circular edge 37 of the element 35 of the steering wheel 33.
  • the element 35 can, thanks to a mounting known per se, slide slightly along the shaft 29 but cannot be rotated relative to this shaft.
  • the rotation of the shaft 29 and the element 35 of the flywheel 33 are obviously integral.
  • the swash plate 20 ′ acts via the cylindrical body 39.
  • the swash plate 20 ′ abuts, in its central part, on the transverse face of the cylindrical body 39 which is integral with the steering wheel element 35.
  • the steering wheel designated by the general reference 33, also consists of two elements, the element of which, fixed relative to the shaft 29, which bears the reference 40.
  • This steering wheel element 40 is equipped with a series of flyweights 41 arranged in a circle inside the rim 42 of the element 40.
  • Each counterweight is subjected to the action of a spring 43 wound on a rod 44 which serves also guide to the corresponding counterweight.
  • the flyweights 41 have the form of wedges, the large base of which is directed towards the periphery of the steering wheel 40 or, again, towards the rim 42 of the steering wheel element 40.
  • the steering wheel element 45 which is rotated by the shaft 29 can execute a certain longitudinal movement relative to this shaft, thanks to a construction which is moreover known per se.
  • the means for guiding the pistons 2'- 2 "and 3'- 3" ensure rigorous linearity in the alternating movement of the sliders 11 moving inside the slides formed by the cylinders 16 or similar cylindrical cavities forming part of the engine block. This rigorous linearity is ensured thanks, in particular, to the design of the mounting between the shells of the ball joints 19 of the oscillating plates 20 or 20 ′.
  • the oscillating movement of the plate is carried out strictly in a single plane comprising the geometric axis of the shaft 20 and the geometric axis of the connecting rods 10.
  • the design of the swash plates 20 - 21 is such that they can, without danger of fatigue which would cause premature wear of their constituent elements, be subjected to extremely high stresses. These stresses come from the forces exerted on the ball joints 19 by means of the slides 11 of the connecting rods 10 and the various pistons 2'- 2 "and 3'-3".
  • the swash plate consists of a ring 47 carrying at least two diametrically opposite ball joints 19 joined to the ring 47 by a collar 22.
  • the ring 47 is mounted on a central bush 48 by by means of a first needle bearing 49 and by a second needle bearing 50.
  • the needle bearing 50 is held in position on the corresponding lateral flank of the crown 47 by a circular element 51.
  • the cylindrical elements of which the needle bearing 49 is made up are alternately composed of two and three coaxial elements. This arrangement is provided to take account of the variations in angular speed which these elements undergo when considering the rotation of the central sleeve 48 with respect to to crown 47.
  • the central bush 48 the internal diameter of the central bore corresponds to the external diameter of the shaft 29, has two external flanks 52 and 53 which are mutually parallel as well as with the plane of symmetry of the crown 47 at height the center line 54.
  • the flank 52 of the central sleeve is cut by a plane which extends at right angles to the geometric axis of the shaft 29. This plane is given in FIG. 8 the reference 55.
  • the part of this plane which is in permanent contact with the external face of the cylindrical body 39 is indicated in solid lines by said reference 55 in FIG.
  • a third needle bearing, or, in the case of pressure lubrication, a plain bearing, forming a circular crown inside the crown 47 is represented by one of these elements under the reference 56.
  • one of the ball joints 19 has a threaded axial bore into which a pin 23 carrying a roller 27 can be screwed, as these elements have been represented in FIG. 4.
