FR2760786A1 - Circular IC engine with oscillating motion - Google Patents

Abstract

The engine has a circular toroid cylinder made from two or more components (1, 2) which are screwed together to form a hermetically sealed structure containing four round pistons, two (5) fixed to the main section of the cylinder and two (6) to an inner shaft (4). The cylinder components are fixed to an outer shaft (3) which performs an oscillating motion together with the inner shaft (4), transmitted to ellipsoid synchronised gears (7, 8) offset at 90 degrees to one another and driving an output shaft (9) via toothed chains (10). The fuel/air mixture intake and exhaust gas outlet is controlled by a plate with orifices (11), while ignition is provided by four spark plugs (12).

  to the inner diameter of the ring. To make a full rotation, there are four explosions.

  i.ntrc each movement, there is intake of exhaust gases or exhaust of gases. burned. The control of these lonclions is done by holes or by valves. Ies oscillating rolation movements are controlled by four elilips pinions (idc.

  With regard to particular embodiments, the combustion chambers could have the form of a circular section with a straight axial or radial base, equipped with pistons in the form of a quarter. The synchronization of the rotating and oscillating opening of myself: that the entrainment in the prisc shaft of the orcc can be milked by chains, belts, gears

  This thermal engine can run on petrol fuel. by vaporization in a carburetor, by direct or indirect injection, as well as with unc in; high pressure ction

  According to particular embodiments, this engine can include a number of

  pistons, combustion chambers and dillSrents spark plugs.

  According to these particular models, the same overall realization of my invention is

  The accompanying drawings illustrate the invention: FIG. I represents a drawing of the exploding parts of the ring-torch cylinder engine with a drive for controlling the oscillating movement and the power take-off by

notched chains.

  FIG. 2 represents a drawing of the exploding parts of the derivative of my invention of the combustion chamber engine in the sector elm of a semicircle with an axial base,

  and a PTO drive by compound lever.

  With reference to the drawing in FIG. 1, the parts of the main cylinder I and auxiliary cylinder 2 with their cylindrical combustion chambers in the form of a ring and the pistons 5 are) hcrmletically assembled and screwed onto the external shaft 3. L, ' inner shaft 4 and the pistons 6 is held movable by an iaç; it oscillates in the housing 1 and 2. According to my drawing, Figure I we see the arrangement of the two pistons 5 on the main part of the cylinder I and two pistons 6 on the inner shaft 4. The ellipsoid pinions 7, one on the outer shaft 3 and the other on the inner shaft 4, are offset by 90 degrees. l.es pinions 8 are fixed integrally also offset at 90 degrees on the PTO shaft 9. L, 'the set of four pinions 7 and 8 is driven and synchronized by the notched chains 10. The plate 1 1 shows the diff '' slow gas inlet and exhaust ports. The four candles 12 are fixed on the part 2 and

  rotate with the motor. This engine is provided with air cooling.

  A derivative of my invention shown in Figure 2 shows a main part 1 and

  ) auxiliary 2, with their chambers in lfrme of a sector of a semicircle and an axial base.

  There, these parts are fixed hcrmétique together, and screwed on the outside shaft 3. The two pistons 6, in the shape of quarter, are fixed on the inside shaft 4 this one being held movable in an oscillating way in the housings I and 2. The two pistons 5 are held in the part of the main cylinder. Two braces 13 are fixed one on the outer shaft 3 and the other on the inner shaft 4. These braces are also held at 90 degrees relative to the great length of their pivoting. A disc 14 with connectors 16 fixed on the power take-off, is placed between the two crosspieces so as to be able to obtain the pivotings 15 of the crosspieces in the notches.!, The pivoting position is alternately a large lever law and once a small lever . l) û at the unpacking of the braces, in a notch 16, we find each 'Ibis with

  two pivots of opposite lengths.
