Definitions

  • the invention relates to an axial piston engine with compressed sweeping chamber, for all means of transport or energy groups.
  • the two-stroke axial motor eliminates the drawbacks mentioned above by the fact that in order to ensure an optimization of the exchange of gases which must generate a high volumetric efficiency and ensure the free movement of the rod-oscillator system, the admission of the clean mixture is done directly in a sweeping chamber, through an admission window made at the bottom of the cylinder and actuated by the primary shaft which is provided with two longitudinal channels, the clean mixture being, under the action of the piston, discharged from the scanning chamber using a scanning window, inside a combustion chamber; between the sweeping chamber and the enclosure of the housing is mounted a separator, consisting of a box fixed on the engine block, a first spherical sleeve mounted between the movable connector and the box, and a second spherical sleeve mounted between the movable connector and the body of the connecting rod; between the first spherical sleeve and the movable connector and between the second spherical sleeve and
  • the two-stroke axial motor which is the subject of the present invention consists of a primary shaft A mounted parallel to the engine cylinders 1 in which work two pistons 2 which form between them a combustion chamber a, pistons which are assembled by a ball joint b with connecting rods B which oscillate during operation.
  • a separator C divides the enclosure of an already known casing into two parts.
  • the connecting rods B are assembled, still using a ball joint c with an oscillator D.
  • the axial motor also includes a sub-assembly E which guides the oscillator.
  • the primary shaft A which ensures the control of the gas exchange and transmits the engine torque to the outside, consists of four sections 3, 4, 5 and 6, which are mounted using wedges 7 and clamping screw 8, so that it can be removed.
  • the central section 4 of the primary shaft A there are at least two longitudinal channels d on the same generators which ensure the admission of fresh air or the fuel mixture from the intake manifold, already known and shown in the drawings.
  • the fresh air or mixture from the intake manifold passes through a window in the already known cylinder block to reach an annular space e created by a jump in the diameter f of the section 4 of the primary shaft A.
  • the fresh air or mixture circulates only when the channels d arrive opposite the intake windows g in the scanning chambers h.
  • the primary shaft A controls the suction of fresh air or mixture into the sweeping chamber h where the entire quantity of air or mixture sucked in is retained, which generates an increase in the high volumetric efficiency.
  • the fresh charge enters the combustion chamber a of the cylinder 1 through the scanning windows i actuated by the pistons 2.
  • the cylinder Under the action of the fresh charge flowing, the cylinder is scanned, the burnt gases being evacuated through the exhaust windows j.
  • the connecting rod B consists of a round rod 9 of a spherical element 10 which works in the spherical joint b joining with the piston 2, the spherical joint c and the oscillator D.
  • the connecting rod B describes a spatial movement, generating a conical surface having an elliptical section, the spatial movement of the connecting rod B being determined by the guide E, by games in spherical bearings k by which the two oscillators have been assembled on the primary shaft A D, and by inherent faults which appeared during the mounting of sections 3, 4, and 6 of the primary shaft A.
  • the separator C provides pendular and translational mobility of the connecting rod B and consists of a box 11 fixed to the already known engine block, a first spherical sleeve 12 mounted between the box 11 and a movable connector 13 and a spherical sleeve 14 mounted between the movable connector 13 and the round rod 9. Between the spherical sleeve 14 and the movable connector 13 and between the spherical sleeve 12 and the box 11, there are annular seals 15 and 16.
  • an anti-friction material for example a bronze alloy, has been mounted on the cylindrical interior surface of the sleeve.
  • the separator C divides the space corresponding to each piston into two spaces, the scanning chamber h and the enclosure of an already known casing.
  • the separation of the space of the casing and the sweeping chamber h generates an increase in the filling efficiency as well as a better sweeping of the enclosure of the cylinder 1 by the penetration in both directions of the fresh mixture existing under pressure in the scanning chamber h through the scanning windows i.
  • the oscillator D consists of a body formed by two flanges 17, bolts 18 arranged radially relative to the body and which make the connection between the body of the oscillator D and the spherical elements 19, which form with the cages at spherical cavity 20 and the bearing 21 the spherical joints C, and of a spherical bearing 22, of a crankpin bearing housing 23, of a crankpin bearing bearing 24 and of the clamping screws 25.
  • the spherical bearing cushion 22 is made of an anti-friction material which allows the slight oscillation of the body of the oscillator D on the spherical head / of the section 5 of the primary shaft A.
  • the crankpin bearing box 23 is fixed by clamping screws 25 on the body of the oscillator D and constitutes the support for the crank pin bearing 24 which can assume all the forces, both radial and axial.
  • Oscillator D is a sub-assembly of the motor which withstands the greatest mechanical stresses because it transforms the translational movement of the pistons 2 into the rotational movement of the primary shaft A using a bearing crank pin m formed by the bearing bearing crank pin 24 of the cylindrical part of the section 5 of the primary shaft A and the spherical bearing k formed by the spherical head / and by the spherical bearing 22.
  • a guide system E consisting of a fork 26 mounted so that it has the possibility of being mounted at the bottom of the casing rotation in the body of the oscillator on a guide rail 27 which is mounted in two radial bearings 28 which gives it the possibility of rotation.
  • the guidance system E gives the oscillator freedom of movement and allows it to assume any pendulum movements of the oscillator.
  • the two-stroke axial engine according to the present invention includes ignition, lubrication and cooling systems similar to conventional systems, already known, and this is why they will not be described in more detail here.
