Definitions

  • the invention relates to an internal combustion engine in modular design with several identical individual machines, each of which has a cylinder block with a cylindrical longitudinal opening and a cylindrical transverse opening arranged perpendicular thereto, a camshaft mounted in the transverse opening with a three-point cam arranged in the inner cavity of the cylinder block, two laterally cylinders with cylinder heads arranged on the cylinder block and coaxial to the axis of the longitudinal opening, two piston parts sliding in the cylinders and connected to one another, combustion chambers being formed between their pin surfaces and the cylinder heads, and two rollers which are fastened to the piston parts via joints and which act on the cams arranged between them concern.
  • rollers of each individual machine are mounted on axles which are fastened to the two ends of a frame which encloses the driven camshaft.
  • the two ends of the frame merge into rods, at the free ends of which a piston is attached, to which a cylinder is assigned.
  • the two cylinders are attached to a cylinder block in which the three-point cam rotates.
  • the structure of the piston group is complicated.
  • the arrangement of the three-point cam between the rollers is complex.
  • the internal combustion engine has large dimensions and is relatively heavy. The vertical force load on the cylinders results in high friction losses.
  • the object on which the invention is based is now to design the internal combustion engine in a modular design of the generic type in such a way that an increase in efficiency can be achieved with a simple construction, low weight and small dimensions by reducing the friction between the piston and the cylinder.
  • the cylinder block consists of an upper cover with a viewing opening and a lower cover and is cruciform in that an upper shell and a lower one in the longitudinal opening corresponding to the upper and lower cover Shell are attached, which together with the cylinders surrounded by water bushes form a cylindrical cavity, that the piston parts are connected to a rigidly assembled piston arranged in the cavity, that the rollers are arranged on spherical joints, so that they fit in any position place the cam, and that the cam rotates in vertical incisions of the piston and in outer incisions of the upper shell and the lower shell.
  • the internal combustion engine according to the invention in modular design has the advantage that its structure is simple and its dimensions and weight are light.
  • the internal combustion engine works with high efficiency, is reliable and easy to repair.
  • the individual machines can be easily replaced.
  • the desired performance of the machine can be set by arranging the corresponding number of these individual machines. The higher the number of individual machines used, the better the torque of the internal combustion engine can be evened out in modular design.
  • the internal combustion engine shown in Figures 1 and 3 in modular design has a cruciform cylinder block 1 with an upper cover 2, which has a viewing opening 3, and with a lower cover 4, whereby a cylindrical longitudinal opening 5 and a cylindrical transverse opening 6 are formed, which are mutually are vertical and their axes lie in one plane.
  • cylinders 7 with water bushings 8 and cylinder heads 9 are attached along the cylindrical longitudinal opening 5.
  • An upper shell 10 and a lower shell 11 are correspondingly attached to the upper cover 2 and the lower cover 4.
  • the upper shell 10 and the lower shell 11 have a step 12 at one end in order to avoid coaxial displacement.
  • a composite piston 14 is arranged, which consists of an upper body 15 and a lower body 16 and end faces 17, with channels for on both sides Sealing segments 18 are provided. Combustion chambers 19 are located between the end faces 17, the cylinders 7 and the cylinder heads 9. Vertical incisions 20 and horizontal incisions 21 are formed on the assembled piston 14. In the upper cover 2 and in the lower cover 4 as well as in the upper shell 10 and in the lower shell 11, external incisions 22 are provided.
  • a spherical joint 23 which has an axis 24 on which a bearing bush 25 sits, on which in turn a bush with a spherical outer surface 26 is arranged.
  • a bush with a spherical outer surface 26 is arranged on the socket with the spherical outer surface 26 .
  • a right spherical segment 27 and a left spherical segment 28 on each of which a roller 29 is seated, which is self-adapting.
  • An upper bearing shell 30 and a lower bearing shell 31 are provided in the cylindrical transverse opening 6, in which a shaft 32 for the cams 33 having three tips is mounted.
  • the three-point cam 33 also protrudes into the vertical notch 20, the horizontal notch 21 and the outer notch 22.
  • the three-point cam 33 geometrically makes a tension engagement with the self-adapting rollers 29.
