Definitions

  • the present invention relates to a new cylinder head prototype with removal of valves and attached components, for four-stroke internal combustion engines.
  • Traditional distribution systems are provided with valves and attached components.
  • the cylinder head object of this invention patent whose scheme is represented in Figure 1, simplified to a single cylinder. It allows to comply with the four times in internal combustion engines in synchronization with the reciprocating movement of the piston, increasing the gas inlet and outlet area as well as achieving the necessary tightness in the combustion chamber.
  • Figure 1 indicates the elementary unit that forms the whole of the invention, referred to in this case to a cylinder, with the possibility of incorporating as many units as cylinders the engine has, either independently or linked in the same rotary axis distributor with as many spherical parts such as cylinders, together with their corresponding closing and sealing elements.
  • the rotating distributor shaft (1) has the intake (8) and exhaust ducts (7), both independent and communicate the chamber (9) in their corresponding time with the external intake (11) and exhaust (10). Its spherical surface (6) allows the sliding contact of the closing sleeve (2), achieving the sealing of the chamber (9) in its corresponding times.
  • the turning movement is transmitted to the rotating rotary shaft (1) by means of a supportive outer pulley (14) that has the possibility of correction in its relative angular position to allow a correct synchronization of the system with the crankshaft.
  • This pulley will also serve to achieve static and dynamic balancing of the distributor rotating shaft (1).
  • another compensation pulley could be arranged at the opposite end of said shaft. Friction is relieved in the contact area of the closing bushing (2) with the spherical surface (6) by means of a compact formed by a graphite ring incorporated into the closing bushing (2) and another self-lubricated material in its upper part which it takes advantage of the residual oil coming from the internal aeration ducts of the engine or vents led to the intake.
  • the supports (12,13) may be by means of sliding bearings with hydrodynamic lubrication and their corresponding sealing elements or suitable bearings may be provided.
  • the lower body (4) and the upper body (5) locate all the mentioned components forming in their assembly the cylinder head assembly.
  • the compression chamber (9) will be made, which will be designed to achieve the required coverage in the compression ratio of the engine.
  • both bodies (5,4) will have the ducts and cavities that form the particular cooling circuit of the cylinder head.
  • the system thus formed can be executed on any internal combustion engine of four times of ignition by compression or caused.

Abstract

Cinq composants essentiels (1, 2, 3, 4, 5) permettent de coordonner les quatre temps du moteur en combinant la distribution des gaz et l'étanchéité dans la chambre de combustion avec le mouvement alternatif du piston. Un arbre rotatif de distribution (1) synchronisé avec le vilebrequin du moteur dispose d'orifices d'admission (8) et d'échappement (7) avec sorties dans la surfase sphérique (6), lesquels communiquent avec le cylindre lors des temps correspondants. Des orifices ne communiquant pas entre eux sont réalisés pour coïncider avec les prises d'admission et d'échappement à l'extérieur. Une douille de fermeture (2) en contact intermittent, coulissant et compensé sur la surface sphérique (6) ainsi qu'un ressort conique (3) permettent d'étanchéifier la chambre de combustion lors de la compression et de l'expansion, et conduisent à travers l'orifice (9) ménagé dans le corps inférieur (4) les gaz d'admission et d'échappement lors de chaque temps correspondant. Un corps inférieur (4) et un corps supérieur (5) logent tous les composants susmentionnés qui forment l'ensemble culasse.
