Definitions
- the invention relates to a crankcase with an integrated ventilation space according to the preamble of claim 1.
- the object of the invention is therefore to produce this calming space to make casting technology more advantageous.
- Figure 1 shows in cross section through a crankcase 1 with bore 2 for receiving a wet cylinder liner 3.
- the blow-by from the crank chamber 4 are 1 relaxation rooms on both sides of the crankcase 5a, 5b are provided.
- the Bore 2 turns 6 in which sealing rings are inserted, which after installation of the liners take over the sealing function for the cooling water.
- the crankcase 1 also has a collar 7 which the large seal of the crank chamber 4 against splash oil.
- the separation of the Crank spaces 4 against each other are made by bulkheads 8 which also the storage chairs Record 9.
- each of the crank chambers 4 is now opened in via a window opening 10 the bulkhead 8 and via bilateral transitions 11a and 11b with the calming rooms 5a, 5b connected.
- the blow-by reaches the crank chamber 4 which is open Window opening 10 and the transitions 11a, 11b as with a broken line and arrow shown to the calming rooms 5a, 5b.
- This is the one below the cylinder liner 3 flows around the same lying part as it follows in Figures 3 and 4 is clarified.
- the particular advantage of this ventilation can be seen in rational production.
- the Casting core for the crank chamber 4 and the calming chambers 5a, 5b can be part getting produced.
- the connection of the cores for the crank chamber 4 and the calming rooms 5a, 5b is through the cores for the window opening 11 and the transitions 11a, 11b accomplished.
- the sections of the core can be used for remove the calming areas 5a, 5b slightly.
- crankcase 1 shows a longitudinal section II-II through the crankcase 1.
- the bulkhead 8, which separates the crank chambers 4, has the one open to the crank chambers 4 Window openings 10 through which the Blow by indicated by arrows occurs.
- the blow-by way is shown in detail in half section in FIG. 3.
- the cylinder liner 3 is against the cooling water via sealing rings which are arranged in the grooves 6 sealed.
- a rough seal against the crank chamber 4 is carried out by the Collar 7 and the cylinder liner 3.
- the bulkhead 8 has the against the crankcase open window openings 10, through which the blow by penetrated by arrow penetrates and reaches the calming space 5a via the transition 11a, which is the crankcase 1 penetrates in the longitudinal direction.
- FIG. 4 A top view of the cylinder liners 1 with window openings 10 and the transitions 11a, 11b shows FIG. 4. After casting, the core sand of the connection spaces can 11a, 11b (Fig. 1) through the openings 12 are removed so that openings can be omitted in the side walls of the crankcase 1.

Claims (2)
- Kurbelgehäuse mit integriertem Entlüftungsraum, bei dem das Kurbelgehäuse Bohrungen für die Aufnahme von nassen Zylinderlaufbüchsen aufweist, wobei die Bohrungen Nuten für die Abdichtung der Zylinderlaufbüchsen gegen das Kühlwasser aufweisen und das Kurbelgehäuse an beiden Seiten in Längsrichtung verlaufende Beruhigungsräume für den Blow by aufweist, dadurch gekennzeichnet, diese Beruhigungsräume (5a, 5b ) zunächst mittels eines Bundes (7) im Kurbelgehäuse (1) und der Zylinderlaufbüchse (3) gegen den Kurbelraum (4) abgeschottet sind, daß die Verbindung des Kurbelraumes (4) mit den Beruhigungsräumen (5a, 5b) durch Fensteröffnungen (10) in den Schottwänden (8) hergestellt werden, welche gegen den Kurbelraum (4) hin geöffnet sind und diese Fensteröffnungen (10) wiederum über Übergänge (11a, 11b) an den Zylinderlaufbüchsen (1) vorbei mit den Beruhigungsräumen (5a, 5b) in Verbindungen (11a, 11b) stehen.
- Kurbelgehäuse nach Anspruch 1, dadurch gekennzeichnet, daß die Gießkerne für die Beruhigungsräume (5a, 5b) und für die Kurbelräume (4) eine Einheit bilden und daß die Verbindung dieser Teile über die Kerne für die Fensteröffnung (10) und die Übergänge (11a, 11b) bewerkstelligt wird.
