Definitions

  • the present invention relates to a four-stroke endothermic engine with rotating drum, having pistons spreading apart with a reciprocating motion.
  • the design of an endothermic engine with a rotating drum i. e. an engine that does not use a crankshaft for the reciprocating motion of the pistons, like in conventional engines, has always been a fixed idea. It has been pursued through different, more or less successful solutions, which had scarce or short applications, apart from one case, the Wankel engine, produced and patented in the sixties. Many of the patents intended for this aim have proved more suitable to the construction of pumps rather than of actual endothermic engines.
  • Said internal combustion engine comprises a drive shaft onto which a cylindrical drum equipped with fixed radial blades is fitted, said shaft being rotatable inside a stationary body, the engine being characterised in that said drum internally defines a cylindrical compression chamber within which two pistons are arranged, which pistons perform a reciprocating rotary motion around the drive shaft to provide for the compression of the combustible mixture; said mixture being introduced into the hollow space defined between the drum and the stationary body, into the cell defined by two subsequent radial blades, and being dragged by the rotary motion of the drum to the burst chamber, the mixture explosion causing rotation of the drum and hence generating the driving force for the whole system.
  • - Fig. 1 is an elevational side view of a longitudinal section of the engine of the invention
  • i - Fig. 2 is a front view of a front section of the engine of the invention
  • FIG. 3 is a detailed view of the device actuating the drive cams of the admission gate.
  • Fig. 4 is a schematic view, similar to Fig. 2, of a variant embodiment including lightened pistons.
  • the engine of the invention essentially comprises: a drive shaft 1; a distribution box 3; a supporting wall 5; a compression chamber 7; a rotating drum 9; a central body 11; and a closing cap 13.
  • Drive shat 1 is a cylindrical linear axle, having fitted thereon a central gear 15 and, on the opposite side, the aforementioned rotating drum 9 which will be disclosed further on.
  • Distribution box 3 froming the external portion of the engine and the end support for drive shaft 1, internally contains:
  • Such cams are integrally formed at both sides of a central wheel 31 acting as a support, and they have different tasks: one of them provides for opening admission port 33, the other for closing same by actuating gate 29;
  • the distribution box also acts as a sump for collecting lubricating oil.
  • Support wall 5 besides performing its support function, includes admission ports 33 through which the gaseous mixture will be sucked. As said, opening and closing are controlled by gate 29, through cams 25, 27.
  • Compression chamber 7 is a cylindrical, hat-shaped chamber, which is to be fastened as shown.
  • Two ejection ports 43, 45 are formed along its side, in diametrically opposite points, and the compressed gaseous mixture will pass to burst chamber 47 through said ports.
  • Two pistons 49, 51 are located within compression chamber 7. The pistons are hinged on drive shaft 1 and their movements are driven by expansion keys 21, 23. Here, drive shaft 1 only acts as a pivot.
  • Each piston 49, 51 has a particular lobe 53, 55, having only safety functions for protecting admission gate 29 from the high pressure due to compression. It is to be appreciated that such lobe will assist in closing admission port 33, but it will not hinder the passage of the compressed mixture though ej ection ports 43, 45.
  • a plurality of curved blades 61 is provided onto the drum periphery, and they have such a height that said drum is allowed to rotate inside the central body.
  • a small cell 63 with side walls 65, 67 is formed between two consecutive blades, and opening port 69 thereof allows the compressed mixture to pass into burst chamber 47, of which said cell is part together with a small recess of the central body, where ignition plug 71 is arranged.
  • a second cell wholly similar to the cell described above, is provided on the opposite side and is spaced apart by 180° with respect to the cell described above. The description of that second cell is obviously omitted.
  • Drum 9 is also integral with the impeller (not shown) of a centrifugal pump for the lubricating oil.
  • Central body 11 is the central portion of the system, and it is shown in cross-sectional view in Fig. 2. It acts as a housing and is equipped with the actual burst chambers 47 and with exhaust manifolds 73, 75.
  • pistons 49, 51 In the opening phase, pistons 49, 51 will generate a gap of about 45° into which the gaseous mixture will be sucked through admission port 33. At the same time, on the opposite side, the same pistons 49, 51, in the closing phase, will compress the previously sucked mixture and will send it towards burst chamber 47 through ejection ports 43, 45. Now rotating drum 9 is made to intervene. The drum, by rotating in counterclockwise direction and at a speed twice that of expansion keys 21, 23, will transfer the compressed mixture, through opening port 69, into burst chamber 47, where plug 71 will cause explosion thereof.
  • Fig. 4 shows a variant embodiment of the engine of the invention, where pistons 49, 51 are lightened, i. e. they have a hollow interior.
  • ducts 81 belonging to the lubrication circuit can pass through the internal cavities of the pistons.
  • keys 21, 23 could be secured onto the respective shafts 17, 19 through strengthening members.
  • a longitudinal partition could be provided within the suction duct for the gaseous mixture, in order to protect gate 29 from the high pressure during the burst phase.

Abstract

L'invention concerne un moteur endothermique à quatre temps pourvu d'un tambour rotatif, constitué essentiellement d'un arbre (1) d'entraînement sur lequel est positionné un tambour rotatif (9) équipé de lames radiales fixes, l'arbre (1) pouvant effectuer un mouvement de rotation à l'intérieur d'un corps fixe (11). L'invention se caractérise en ce que ledit tambour (9) définit une chambre de compression cylindrique dans laquelle sont disposés deux pistons (49, 51) exécutant un mouvement rotatif alternatif autour de l'arbre (1) d'entraînement afin de permettre la compression du mélange combustible. Ledit mélange est introduit dans l'espace creux défini entre le tambour (9) et le corps fixe (11), dans la cellule (63) définie par deux lames radiales consécutives, et entraîné par le mouvement rotatif du tambour dans la chambre (47) d'explosion, l'explosion du mélange entraînant la rotation du tambour (9) et générant ainsi la force d'entraînement pour tout le système.
