COOLING DEVICE FOR INTERNAL COMBUSTION ENGINES Filed Aug. 18, 1931 Patented Mar. 22, 1932;
UNITED STATES PATENT OFFICE.
OSCAR SIMMEN, OF ERLAGH, SWITZERLAND, ASSIGNOR T FIRM" SULZER FRERES SOCIETE ANONYME, OF WINTER-THUR, SWITZERLAND COOLING DEVICE FOR'INTERNAL COMBUSTION ENGINES Application filed August 18, 1931,,Seria1 No.
' the valves is taken from the medium for cooling the cylinders before this medium enters the cooling chambers of the cylinders. The cooling medium is circulated through the valve cooling chambers in series, while it flows in parallel through the cooling chambers of the cylinders. v The object of this arrangement is to supply each portion to be cooled with the correct quantity of cooling medium and to reduce to a minimum the throttling of the quantity of the cooling medium passing through.
One construction according to this invention is illustrated by way of example in the accompanying drawings, in which Flgure 1 1s a sectional elevation of a single-acting internal combustion engine according to this invention, and
Figure 2 is a plan showing diagrammatically the application of the arrangement shown inFigure 1 to a six'cylinder internal combustion engine.
In the construction illustrated the engine comprises a bed plate 1 closed by a sump 2 and having mounted upon it a supporting frame 3 which carries the cylinders 1. Each cylinder is provided with a cylinder head 5 in which is mounted a fuelinjection valve 6 having a cooling chamber. Reciprocating Within the cylinder is a piston 7 from which the-forces are transmitted by means of a piston rod 8, a crosshead 9 and a connecting rod 10 to the crank 11.
As shown the cooling jackets 12 of the cylinders 4 have cooling medium delivered to them in parallel by pipes 13 from a common supply passage or manifold 14, this cooling medium flowing from the cooling jackets 12 through pipes 18 into the cooling chambers ofthe cylinder heads 5 from which it is discharged into a common discharge pipe or manifold 19.
The cooling chambers of the fuel injection valves 6 are, in known manner, connected together in series and cooling medium is supplied thereto from the supply manifold 14;
557,803,'and in Switzerlandv August 28, 1930.
through a pipe 15 and is discharged through a pipe 16 separately from the cooling medlum from the cylinders so that the flow of coollng medium through the cooling chambers of the fuel injection valves can be observed. A control valve 20 may beprovided 1n the pipe 15 for varying the flow of cooling medium through the coo-ling chambers of the fuel injection valves.
If the crosshead guides are provided with cooling chambers then the cooling medium may be passed through these cooling chambers before passing to the cylinder cooling jackets. I The arrangement according to the present invention has the advantage that the cooling of the fuel valves may be regulated from asingle point of control and that all valves may equally be cooled even if the resistance to flow of the cooling medium is different in the single valves.
I claim: I
In a Inulti-cylinder internal combustion engine, in combination cylinders each receiv-' ing a reciprocating piston, a acket surrounding each of said cylinders, a cylinder head for each cylinder provided with a cooling chamber, a fuel injection valve having a cooling chamber arranged in each of said cylinder heads, a cooling medium supply manifold common to all sad cylinders, a branch pipe leading from said manifold to each of said cylinder jackets for delivering cooling medium in parallel to said cylinder jackets, pipes connecting said cylinder jackets to the cooling chambers of said cylinder heads, pipes connecting each cylinder jacket to a common discharge tube, and a pipe branching from said manifold and connecting in series all cooling chambers of said fuel injection valves.
In testimony whereof I ha-ve affixed my signature.
OSCAR SIMMEN.
