Definitions

  • the invention relates to a gas exchange valve of an internal combustion engine according to the preamble of patent claim 1.
  • Such gas exchange valves are known for example from W099 / 16295 and US 2,398,514.
  • the invention is concerned with the problem of minimizing the stresses which occur on the valve disc, in particular in its base region, due to temperature and combustion chamber pressure, by means of an optimized disc geometry, in particular in its base region, while at the same time minimizing wall thicknesses. In doing so, particular attention should be paid to the overall deformation of the valve with regard to a displacement of the valve stem on the one hand and the deformation of the valve base between the support in the center of the base and the outer base area under combustion chamber pressure on the other hand.
  • the invention is based on the general idea of reinforcing the valve base in the case of an overall convex shape by means of ring-shaped bead areas which run around the valve axis and each have a convex outward-facing cross-section.
  • a single such ring bead which can also be referred to as a toroidal section, between the inner support on the valve stem and the outer connection to the valve cone can be sufficient.
  • a plurality of annular beads arranged concentrically to one another within the valve base can also be provided.
  • the central region of the valve base when it adjoins a hollow valve stem, can be convex or concave to the outside.
  • the individual elements of the gas exchange valve according to the invention are generally welded to one another when the valve is made of metal.
  • valve cone which is generally used in practice, “cone” with regard to its shape is not to be understood strictly mathematically, but rather in the sense of any funnel shape.
  • the valve base closes the valve cone via a connecting collar on.
  • the connection is made in such a way that the radially outer edge areas of the valve base in the form of the connecting collar on the one hand and the valve cone on the other hand lie in a conical surface formed by the lateral surface of a fictitious cone built in the valve axis with a tapering in the same direction as the valve cone run out together towards the cone base surface.
  • hollow valve disks also show in longitudinal cross section
  • valve base reinforced by a single ring bead
  • FIG. 2 a valve base according to FIG. 1 with a radially outer connection collar
  • FIG. 3 shows a valve base according to FIG. 2 with a valve stem widened within the valve plate
  • FIG. 4 shows a valve base according to FIG. 1 with an additional, convex design in the central area
  • FIG. 5 shows a valve base in a basic form according to FIG. 2 with an additional ring bead and a support cone within the valve plate.
  • valve plate made of metal are welded to one another without the weld seams being shown as such.
  • the valve disk according to the invention according to FIG. 1 comprises a valve base 1, a hollow valve cone 2 and a hollow valve stem 3.
  • the valve base 1 is welded to the hollow cylindrical valve stem 3 on the one hand and the outer edge of the valve cone 2 on the other hand.
  • the tapered end of the valve cone 2 is also welded to the valve stem 3.
  • the above-mentioned components which are connected to one another jointly form a rigid rotational surface structure.
  • the valve base 1 has a largely flat, central area 4 in the center of the base.
  • the ring area lying between this central area 4 and the outer edge of the valve base 1 is designed as an annular bead 5, which can also be referred to as a torus section, with an outwardly convex curvature.
  • a connecting collar 7 is additionally formed between the ring bead 5 and a radially outer joining area 6 between the valve base 1 and valve cone 2.
  • the connecting collar 7 adjoins the valve cone 2 in a connecting surface which is formed on a conical surface, which is erected in the valve axis and has a taper which is the same in relation to the valve cone 2.
  • the connecting collar 7 and the adjacent edge area of the valve cone 2 run out together in this conical surface in the direction of the conical base surface.
  • valve stem 3 with an area 8 widened inside the valve is used.
  • This widened area 8 provides improved support for the valve base 1 in its central area.
  • valve stem 3 1 inside the enlarged area 8 of the valve stem 3 is convexly curved outwards in a central area 9.
  • FIG. 5 is based on a basic valve shape according to FIG. 2. In contrast to the embodiment according to Fig.
  • a support cone 10 is provided in the interior of the valve cone 2. In its tapered area, this support cone 10 is welded to the valve stem 3. The support cone 10 is also welded to the valve base 1. The area in which the support cone 10 is welded to the valve base 1 lies between ring beads 5 ′ and 5 ′ that are formed concentrically to one another in the valve base 1. 11, both of which have a convex cross-section.
  • the valve base with two concentric annular beads 5 ', 11 has particularly good stability. All of the features shown in the description and in the following claims can be essential to the invention both individually and in any form.

Abstract

L'invention concerne une soupape d'échange des gaz d'un moteur à combustion pourvue d'une tige (3) de soupape, en particulier creuse, et d'une tête de soupape, ladite tête de soupape présentant une base (1) de soupape et un cône (2) de soupape creux, relié au bord extérieur de cette dernière et dont la section décroît à mesure qu'elle s'éloigne de la base, ladite tige (3) de soupape traversant le cône (2) de soupape creux, laquelle tige est, d'un côté, solidement reliée à la base (1) de soupape et, de l'autre, reliée à l'extrémité à section décroissante du cône (2) de soupape, et l'extrémité de la tige (3) de soupape, reliée à la base (1) de soupape, s'étendant au-delà du plan de liaison entre le cône (2) de soupape et la base (1) de soupape. L'objectif de cette invention est d'améliorer ladite soupape d'échange des gaz du point de vue de sa stabilité et de son endurance. A cet effet, cette soupape d'échange des gaz se caractérise en ce que la base (1) de soupape présente au moins une rainure annulaire (5 ; 5', 11) radialement adjacente, pourvue d'une surface de section transversale convexe vers l'extérieur, dans la zone annulaire située entre sa liaison avec la tige (3) de soupape, d'une part, et avec le cône (2) de soupape, d'autre part.
