KNUT JONAS ELIAS HESSELMAN, OF STOCKHIQLM, SWEDEN.

CYLINDER-HEAD FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Yatent.

Patented Aug. 18,

Application filed February 24, 1913. Serial No. 750,351.

To all whom it may concern:

Be it known that I, KNUT JoNAs ELIAS HESSELMAN, a citizen of the Kingdom of Sweden, residing at Stockholm, Sweden, have nvented new and useful Improvements in Cylinder-Heads for Internal-Combustion Engines, of which the following is a specification.

This invention relates to internal combustion engines and more especially to such water-cooled heads thereof that are formed with an aperture extending through the head and adapted to take up a fuel nozzle.

The object of the invention is to attain a more effective cooling of the said fuel nozzle than heretofore by compelling a part of the cooling water passing through the head of the cylinder to fiow axially along the walls of the said opening before it leaves the head.

The invention consists, briefly, in the provision of a water chamber surrounding the said opening and separated from the other water space of the head, said chamber being provided with an inlet for the water at the end facing the cylinder and with an outlet for the water at the other end.

In the accompanying drawing I have shown two embodiments of my invention.

Figure 1 shows a cylinder head seen from above and Fig. 2 shows a sectional view on line A'BC of Fig. 1. Fig. 3 shows another head in axial cross section.

Referring to Fig. 1, the head 1 is in well known manner formed with a central aperdesigned at its inner end to communicate with. the explosion chamber of an internal combustion engine. The Water space. of the head is by means of an intermediate wall 3 divided into two chambers 4t and 5 of which the inner one 4 surrounds the aperture 2 and at its lower end communicates. with the outer chamber 5 through a series of ports 6 in the said intermediate wall 3. At the upper end the inner chamber a is provided with an outlet 7, and in the lower portion of thesame chamber 4 maybe provided radial wings or walls 8 adapted to prevent the water flowing in through the ports 6 from flowing in peripheral direction Within the chamber 4.- The outer chamber 5 is adapted to communicate in the usual manner with the Water jacket of the cylinder through ports 9 after the head 1 has been placed in position on the cylinder.

In the constructional form shown in Fig. 3 the chamber 4 formed between the intermediate Wall 3 and the walls of the aperture 2 is in direct communication with the water jacket of the cylinder after the head has been placed in position on the latter. The connection is established by means of one or more channels or ports 10 in the wall of the head facing the cylinder, said channels ending in the lower end of the chamber 4. At the other end the chamber 4 has an outlet 7. In-the constructional form shown in Fig. 3 water may be supplied to the other water space 5 of the head 1 for instance through an aperture 11 in the wall of the outlet 7 or it may be supplied in the usual manner direct from the water jacket of the cylinder.

The constructional forms shown in the rawing may eventually be combined with each other in such a manner that the water flowing axially through the chamber 4 is taken partly direct from the water jacket of the cylinder partly from the water space of the head 1. I

Having now described my invention what I claim as new and desire to secure by Letters Patent is:

l. A cylinder head for internal combustion engines having an aperture extending through the head and open at the inner sine of thehead and adapted to takeup a fuel nozzle and also having an intermediate wall surrounding and spaced from the wall of said aperture and dividing the interior of the head into inner and outer water-receiving chambers, means for letting waterinto and out of the outer chamber, means for letting water into the inner chamber at end thereof, and means for letting water 01."; of the said chamber at the other end thereof.

2. A cylinder head for internal combus tion engines having an aperture extending through the head and open at the inner side of the head and adapted to take up a fuelnozzle and also having an intermediate wall surrounding and spaced from the wall of said aperture and dividing the interior of the head into inner and outer water-receiving chambers, spaced radial walls, of less length than the inner chamber, arranged in said chamber and extending between the Wall of the aperture and said spaced wall, means 1fler lgetting wate; inltomand out of the outer C am er means 01 e in Water II] 0 the inner chamber at one end %hereof, and KNUT JONAS A HESSELMAN' 5 means for lettin Water out of the said Witnesses:

chem er at the ot er end thereof. CONRAD MUNN,

In testimony that I claim the foregoing RUTH PETERSSON.

as my invention, I have signed my name i1 presence of two subscrlblng wltnesses.
