1 0 (ZZZ whom it may concern Be it known that I, KURT HrnnLn, en ginecr. whose post-oiiice address is No. llaslerstrasse, ,at Nuremberg, Bavaria, in the Empire of Germany, have invented cer tain new and useful Improvements in Cylinders for Combustiomlfingines; and. I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as willenable others skilled in the art to which it appertains to make and use the same.
This invention relates to power cylinders for internal combustion engines, in which are entirely or partly arranged In such cylinders, the basal form of which is illustrated in Figure 1 those points, at which the valve connections cylinder Z), corner pieces 0 arise, which are badly cooled as well as very highly strained by tensile stresses and therefore easily crack. .A strengthening of these parts by accumulation of material would lead to a further decrease in the cooling and thus would increase the danger of formation of heat cracks. The strengthening of the endan gered point by the insertion of bolts or the casting in of special resistant material, for instance ingot iron rings, is only possible in a limited degree, without-harmfully influencing the cooling and producing dangerous localstrains' Also the casting in of special water pipes into these parts offers no satisfactory solution, on account of thedificulties and during the manufacture and operation, especially in large cylinders with numerous valves. v v
My invention has for its object to radically remove the source of danger by transferring the tensile strains, which in combination with the heat strains, are very the endangered corner pieces into a well cooled region having a cross section of any desirable strength and at the same time by abundantly cooling the.
danger point by directing the entire cooling water past said point. 7
L y invention consists in arranging beg. neath the valve conneet1on, an annular rib,
which connects the'innercylinder with the outer shell.

Whereas in a normal cylinder (Fig. l) the piece 0 in Fig. l, in a cylinder as illus' trated in Fig.
2, the tension said pressure,
produced b is distributed y that is, to the" double-shaded face 0 l, 5, 6 of Fig. 2. The will then be so distributed in the sections 0 1, 5, 6, that they are least in the endangered sectional sur corner piece; for the said annular rib, which remams cooland counteracts the heat expansion of the hot inner cylinder, exercising thereby a pressure which by the amount of its own strength reduces the tensile strain to which the corner piece 0 is subjected on account of they explosion. manner, the outer flange f of the cylinder releases the corner piece d from its strain. The said continuous annular rib however does not-onlyremove the cause for the, pro namely, a too high tensile strain, but it also effectually prevents the insufficient cooling of the endangered point.
The separation of the space for the cooling water at the ends of the cylinder, due to the said rib, permits. the whole quantity of 0001- mg water to be directed straight to the Valve connections through holes arranged close to i the innerv wall of the 03 oughlyeffective cooling of the. endangered point a is obtained by the high and the water striking against the valve in this case, the entire quantity of cooling. water is-driven forward the effect is considerably greater than if thd squirted with speendangered points were cial water, in the well own manner.

In Fig. 4 the axial forces are transmitted by the outer jacket, which is therefore more strongly constructed. The annular rib e is formed as a flange for securing the outer jacket. In order to be able to guide the" cooling water close to the inner shell of the cylinder, a special guiding rib 2' is provided on the jacket h. The passage holes is for the cooling water are so arranged in the annular rib e; that they lie directly beneath the valve connections a.
. According to Fig. 6 the annular rib e lies so close beneath the valve connections a that same partly merge with the annular flange. The water is then directed through two holes on each side of the connections.
In Fig. 5 the annular rib e does not touch the supports. In this case one hole 70 is sufficient for the passage of the cooling water.
