INTERNAL-COMBUSTION ENGINE WITH A OF OF KUEHLWASSER FLOWED THROUGH CYLINDER BLOCK.

towards:

Fig. 1 an axial section dutch the top of a cylinder and a part of the Zylinderdeekels, Fig. 2 in gr Ssserem yardstick as in Fig. 1 a set memo dutch the upper end of the cylinder employment with Sammelkammer and withdrawal chamber ffir the Ktihlwasser and Fig. 3 a horizontal cut by the chambers entspreehend the line III III in Fig. 1.

In accordance with, s Fig. 1 is in cylinder block-goes iuse 1 to a Dieselbrennkraftmasehine e.g. the V-design a cylinder employment 2 arranged, in which a piston is abbeweglich 3 aufnnd, which is linked at a connecting rod 4. The cylinder employment 2 outstanding with its upper end from the cylinder block exhibits a flange rising up outward, with which it rests on the Zylinderblockgehiiuse 1 at this end. Between cylinder block-go use 1 and to the cylinder employment 2 is intended a ringf6rmiger, wasserdurchstrSmter Kiihlraum 6. The wall of the Zylinderblockgehiiuses 1 drew in against its upper end something and rests with this drawn in section 7 the cylinder employment 2 sealing. Accordingly also the lower, not represented end of the Zylinderblockgehiiuses 1 something drew in and rest sealing against the cylinder employment 2. is on the cylinder employment 2 rests the ZylinderdeckeI 9, which distributed more tiber several, fibre the range of the cylinder employment and in the Zylinderbloekgeh iuse 1 fastened studs 8 is connected with this 16sbar. The Zylinderdeekel 9, which exhibits a Brennstoffeinspritzdiise of 10, not drawn Einund exhaust valves as well as a Arffahrventil 11, enthiilt several wasserdurchstr6mte Riiume 12, 13, those among themselves in nieht niiher represented way in connection stehen.

In the range of the flange 5 of the cylinder employment 2 as well as the wall section 7 cylinder block-go iuses I are in the z5 cylinder employment 2 fibre the extent gleichmgssig distributes 48 straight-lined and rising running Kan ile 14 intended, with its lower end into the ringf6rmigen the Kiihlraum 6 to miinden. Above the flange 5 the cylinder employment 2 is surrounded yon a ringf6rmigen, two concentric, ineinanderliea0 gende chambers 16 and 17 containing Hohlk6rper 15 diehtend, that on the flange 5 rests (Fig. 2). Into the internal, all around passing chamber 16 the 48 Kane 14 mfinden, by being ingert at their upper end of fibre one radial channel each 14j to znm iusseren extent of the Zylindereinas of set of 2 verl. Thus the internal chamber 16 forms a collecting area fiir from the ringf6rmigen the Kfihlraum 6 ago 14 ile by the Kan, 14j strSmende Kfihlwasser. Between the internal chamber 16 and the iiusseren chamber 17 a partition 20 passing all around is intended, those in the sketch of the Hohlk6rpers 15 after a regelmiissigen eight-hits a corner verl inft (Fig. 3). At each Eeke this Aehteeks bulges out the partition 20 to close to the cylinder employment 2 out, so that the chamber 16 aeht dureh in such a way formed Verdikkungen of the partition in sections is subdivided, those in as 615,980 Drnckausgleich with one another. At each Ausbanchnng of the partition 20 a durehgehendes hole 21 is intended, by sees in each case one that above erw to ihnten studs 8 extended. Between two bulges each a Drossel6ffnung 22 is intended, the Kiihlwasser from the zugeh6rigen Abscbnitt of the chamber 16 into the iussere chamber 17 fibre-stepped fibre those in the partition 20. This chamber 17 exhibits only one Austritts6ffhung 23 on the top side of the Hohlk6rpers 15, to in not niiher represented way the line 25 (Fig. 1) is attached, those the chamber 17 with the Wasserriiumen 12, 13 in the cylinder cap 9 connects. In the line 25 a shutoff device is zweckrniissig vorgesehen.

As best from Fig. , str6mt is evident to 2 in the enterprise of the internal-combustion engine the Kfihlwasser from the Kfihlraum 6 14 of the cylinder employment ile into the Kiihl Kan 2, wodureh these in its upper, temperaturund druekmiissig at the stiirksten stressed range is gekiihlt intensively. From the Kaniilen 14 the Kiihlwasser fibre the radial Kaniile 14/arrives into the internal chamber 16, whereby the eight ilen gleichm issig fibre the extent of the partition 20 distributed throttle points 22 ffir a among themselves gleicbmiissige exhaust velocity of the water from the Kan 14/ensure. The cross sections of the throttle points 22 are so limited the fact that the Wassergesehwindigkeit is larger at least in the square in the throttle points 10maI as in the cross sections of the KanSle 14/and in the cross sections of the closest places zwisehen the Verdiekungen of the partition 20 and after passing the throttle points 22 arrives to the iiusseren wall 18 of the Hohlk6rpers the Kiihlwasser into the iussere hammer 17, in that it at the Austritts6ffnung 23 str6mt and fibre this as well as the line 25 (Fig attached to it. 1) the Hohlk6rper 15 verl eats. From the line 25 the Kiihlwasser arrives into the Hohlriiume 12 and 13 of the cylinder cap 9. when dismantling the cylinder cap is only the connection of the line 25 too lessen.

Abweiehend of the descriptive Ausfiihrungsbeispiel is it aueh m Sglich to arrange the Austritts6ffnung 23 in the iusseren wall 18 of the Hohlk6rpers 15. It is further m6glich that the iussere chamber 17 about only fibre three-quarter of the extent of the Hohlk6rpers 15 erstreekt itself, as at the two ends of this chamber the partition 20 with the iusseren wall 18 is zusammengeftihrt. The iussere wall 18 verl iuft then, deviating yon in Fig. 3 drawn circle, in the Absehnitt the two ends of the chamber 17 in smaller distance to the cylinder employment 2. such an organization necessarily zwisehen can from Platzgriinden sein.
