Description

sT'rEs ERNST DAIBER AND PAUL A. BITTER, or KIEL, enari'ifiiv;
. COOLING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
To all whom it may concern:
Be it known that we, ERNST DAIBER and PAUL A. BITTER, citizens of the German Em .pire, residing at Kiel, Germany, have invented certain new and useful Im rovements tuations in temperature. These fluctuations in-temperature cause non-permissibly high strains of the material with at times consequent appearance of cracks in the walls, particularly where the straight'wall surfaces are interrupted, as for instance, at the edges of the valve openings. This is avoided in the present invention by providing thinwalled, water cooled. chambers around the inlet openings of the valves situated in the walls of the compression chamber, andv through which the valve cages are drawn.
Two embodiments of the present invention are illustrated in the accompanying drawing, and Figure 1 shows a vertical longitudinal section of the part in question of the working cylinder of an upright. two-strokecycle internal'combustion engine, the valves of which are situated in the cylinder cover, while Fig. 2 is a similar' representation of the same kind of engine, in which the valves are arranged in the walls of the cylinder.
The embodiment illustrated in Fig. 1 will first be described. A is the double walled working cylinder, B the -cylinder cover, and C the working piston. The necessary valves are situated in the cylinder cover, but onl two scavenging valves are shown.
n accordance with the-present invention, the inlet openings for the valves, provided in the compression chamber are' inclosed by exchangeable cooling chambers, which impinge with their upper end faces against the cylin er cover B, and these individual,
valve 2 inclosures are united into a single cooling chamber E for the sake of simplicity when ithe valves are situated close together. In order to facilitate the carrying ofl of the heat as far as possible, the walls of this cooling chamber, which are situated towardv the combustion chamber, are made very thin. The valves. D, leading through the cylinder cover and penetrating the cooling specification of Letters Iatent. t t Apt 25, Application filed June 15, 1914; Serial No. 845,505. l I
chamber E are, however, not packed against the latter, but against the cylindercover B, norder to avoid any straining of the cool ing chamber. The admittance and removal of the cooling water to and from the cooling chamber E takes place through pipes F and F which connect the cooling chamber with the cool Water chamber of the cylinder. The cooling chamber E can be produced and fimshed cheaply, and may, when necessary, easily be replaced by others, kept in store';
The embodiment of the invention illus trated in Fig. 2 differs from the one shown in Fig. 1, principally thereby that the necwalls only one scavenging valve D however, being shown in the drawing. The water cooled individual inclosing chambers, provided at the entering place of the valves, are also in this embodiment, for the sake of simplicity, united into a closed cooling ring. E which is provided with ahollow, water cooled bottom, reinforced b webs, forthe simultaneous protection 0 the cylinder cover, which feature, however, does not'conso f stitute the main object of the invention.
The admittance and removal of the water in the cooling chamber E is accomplished by means of special pipes G, G provided in the cover B 1. A cooling device for internal combustion engines, having a cylinder cover over ts combustion chamber, said device comprising a hollow member beneath said cover inserted at the combustion end of the cylinder, said member having apertures tor re ceiving the valve cages and completely inclosed spaces for coolingffiuid; surroundlng said valve apertures.
2. A cooling device for internal combus-' tion engines, having a cylinder cover over its combustion chamber, said device comprising a hollow member at the combustion end of the cylinder, said member having apertures for receiving the valve cages and completely inclosed spaces for cooling fluid,
surrounding said valve apertures, the walls.
of said member facing the combustion chamher being vcrv thin. v
3. A cooling device for internal combustion engines, having a cylinder cover over its combustion chamber, said device comprising a hollow member atthe combustion end of the cylinder, said member formiugthe combustion chamber and having apertures essary valves are arranged in the cylinder,"
cooling fluid therethrough;
4:. A cooling device for lnternal combustion engines, having a cylinder cover over' its combustion chamber, said device comprising ahollow member at the combustion end of the cylinder, said member forming thecombustion chamber and having apertures for receiving the valve cages and coinpletely inclosed spaces for cooling fluid, surrounding said valve apertures, said spaces intercommunicating to form a continuous inclosed chamber and conduits connecting the inclosed chamber or chambers with a cooling fluid storage. 5
In testimony whereof the foregoing speci fication is signed.
