  Umsteuerbare Druckluftanlassvorrichtung für Verbrennungskraftmaschinen. 



   Den Gegenstand der Erfindung bildet eine umsteuerbare Druckluftanlassvorrichtung für Verbrennungskraftmaschinen, und zwar jener Art, bei welcher der Steuerschieber für die Regelung der Anlassluft von dem Steuerschieber, durch den die Umsteuerung erfolgt, mantelförmig umschlossen wird. Hiebei ist gemäss der Erfindung die Anordnung so getroffen, dass die Achse des Umsteuerschiebers und die sie axial durchsetzende Achse des   Anla/3stauerschiebers   das Gehäuse an der einen Stirnwand durchdringen, an das an der offenen Seite der beiden Schieber der   Anschlussstutzen   für die Zuleitung der Anlassluft angeschlossen ist. Hiedurch werden beide Schieber axial gegen das geschlossene Stirnende des Gehäuses gedrückt.

   Der Abschluss des Gehäuses durch den Anschlussstutzen lässt eine sehr einfache und gut wirkende Dichtung zu, so dass Druckverluste leicht vermieden werden können. 



   In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes in Anwendung für eine umsteuerbare, sechszylindrige Maschine zur Darstellung gebracht und zeigt Fig. 1 einen Längsschnitt, Fig. 2 einen Querschnitt durch die Anlasseinrichtung. 



   Die Wirkungsweise der Vorrichtung ist folgende :
Die Anlassluft tritt bei geöffnetem Absperrventil des   Luftbehälters   durch den   Anlass-   stutzen a in das Gehäuse b ein und gelangt so in das Innere des   Antasssteuerschiebers   e, der gegen die Einströmung a zu offen, am anderen Stirnende durch die Wand f geschlossen

  Reversible compressed air starting device for internal combustion engines.



   The subject of the invention is a reversible compressed air starting device for internal combustion engines, specifically of the type in which the control slide for regulating the starting air is encased in the form of a jacket by the control slide through which the reversal takes place. According to the invention, the arrangement is such that the axis of the reversing slide and the axially penetrating axis of the stop valve penetrate the housing at one end wall to which the connection piece for the supply of the starting air is connected on the open side of the two slides is. As a result, both slides are pressed axially against the closed front end of the housing.

   The closure of the housing by the connecting piece allows a very simple and effective seal, so that pressure losses can easily be avoided.



   In the drawing, an exemplary embodiment of the subject matter of the invention is shown in use for a reversible, six-cylinder machine and shows FIG. 1 a longitudinal section, FIG. 2 a cross section through the starting device.



   The device works as follows:
When the shut-off valve of the air tank is open, the start-up air enters the housing b through the starter connection a and thus gets into the interior of the contact control slide valve e, which is too open against the inflow a and is closed at the other end by the wall f

shaft can be connected. The starting control slide e is encased in the form of a jacket by the reversing slide p, which is also too open against the inflow a and closed at the other end and carries a hollow drive shaft which is axially penetrated by the axis y of the starting control cylinder e. As shown in FIG. 2, the pipe connections are arranged in two rows and, according to FIG. 1, offset from one another by zoo. By turning the starter control slide, the starting air is directed to the relevant cylinder door. The reversal is carried out by.

Rotation of the reversing slide p by means of the lever r, which is connected to the other reversing of the machine by a linkage of any type. The machine is started by simply opening the shut-off valve on the pressure air tank, whereupon the machine starts up immediately, after which the shut-off valve on the compressed air tank must be closed again when the ignition is started PATENT CLAIM:

Reversible compressed air starting device for Ververunungskraftmaschinen, characterized in that the axis of the changeover slide and the axially penetrating axis of the starting control slide penetrate the housing on one end wall to which the connection piece for the supply of the starting air at the second end, on which both slides are open is connected in order to achieve a tight seal of the housing with the most friction-free play of the two slides and thus avoid pressure losses. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
