Definitions

  • This invention relates to an air or gas compression system carried by piston along the cylinder which has diametrically located openings distributed in order to determine the compression ratio.
  • the compression piston is a generally cylindrical piece that is carried inside each one of preferably a plurality of cylinder chambers.
  • Each cylinder has a piston in its chamber.
  • This piston component is most often cast in light alloy and moves rectilinearly in two directions, up and down within its cylinder chamber, and its main role is to receive, when at its upper position within the cylinder chamber, the explosion of the mixture of air and fuel.
  • the explosion of the fuel/air mixture generates a mass movement of expanding gases within the combustion chamber and the piston receives this force and moves away from the head of the cylinder chamber, thus enlarging the chamber space.
  • geometries, and forms the pistons have different functions depending on the type of equipment in which is installed.
  • the compression height is the distance between the top and center of the existing hole in the piston pin. This height is an important measure because through it we can be sure that the piston is at top dead center with the correct distance in relation to the head, thus obtaining an appropriate rate for combustion.
  • a piston compression system has 4 time being the admission, when the cylinder is filled with air and fuel, the compression of air and fuel, the combustion that pushes the piston down and finally the elimination of the exhaustion gases.
  • the compression height i.e., of the area that will effectively carry out the compression of air or gas, is the distance between the top of the cylinder cavity and the center hole of the piston. It is through this length that we know if the piston is at the right point and the correct distance in relation to the cylinder in order to obtain an appropriate rate of combustion.
  • a system of compression by pistons in order to achieve the desired compression, it is necessary to provide a predetermined space in relation to the head of the cylinder when the piston is at its highest position, i.e., top dead center.
  • the present invention consists of the air or gases compression system carried by the piston where, to solve the existing problems in the prior art, openings are placed along the walls of the cylinder.
  • the portion of the piston stroke that will represent the active part of the gas compression is where these openings are closed.
  • the cylinder must have at least two openings always diametrically distributed through the cylinder walls to the chamber within the cylinder body.
  • Figure 1 represents a front view of a compression system found in the state of the art
  • Figure 2 represents a vertical cross-sectional view of the compression system shown in Figure 1 ;
  • Figure 3 represents a vertical cross-sectional view of a preferred embodiment of a compression system in accordance with the present invention in which the piston is located at a position within the cylinder at which the longitudinal openings along the cylinder body are exposed;
  • Figure 4 represents a vertical sectional view of the embodiment of a compression system as shown in Figure 3 in which the piston has moved vertically within the cylinder such that the longitudinal openings along the cylinder body are almost closed.
  • one embodiment of a compression system 10 in accordance with the invention comprises a cylinder (40) carrying within it a compression piston (20).
  • the cylinder (40) in which the piston will act includes at least two openings (30) passing through the peripheral wall of the cylinder 40. These openings 30 are specifically sized in relation to the total stroke of the piston 20 as it moves between top dead center and bottom dead center.
  • a specific part of the piston stroke to be the active part of the compression, i.e., that part where the compression will actually be held.
  • a piston 20 in motion will only begin the work of compression when it reaches the end of the openings 30 and thus closes off the openings 30. As the piston 20 is rising and there remains a part of at least one of the openings 30 still visible there will be no compression. When the piston 20 completely covers the last opening 30, then gas compression will start.
  • openings 30 are preferably diametrically arranged according to the size of the equipment. Thus, it allows us to define in which part of the course of travel of the piston 20 within the cylinder 40 will the compression of air or gases effectively occur.
  • the system 10 has four longitudinal openings 30 spaced symmetrically around the cylinder 40.

Abstract

La présente invention a trait à un système de compression gazeux qui comprend un cylindre creux doté d'une paroi de cylindre, un piston doté d'un mouvement de va-et-vient supporté à l'intérieur du cylindre, et une tige de piston connectée au piston. La commande de la compression gazeuse à l'intérieur du cylindre est déterminée en créant au moins deux ouvertures pouvant être fermées à travers la paroi de cylindre qui sont fermées lorsque le piston doté d'un mouvement de va-et-vient s'approche du point mort haut à l'intérieur du cylindre. Les ouvertures sont disposées de manière à être espacées et de préférence diamétralement opposées l'une par rapport à l'autre.
