Description
Drucklnftmaschine. Der Gegenstand der Erfindung betrifft einfach wirkende Druckluftmaschinen, die mit mehrfacher Expansion und mit mehr als drei Zylindern arbeiten. Kapselt man bei diesen nach -Art der geschlossenen Motoren den Kurbelraum, so entstehen in diesem Raum .infolge der Bewegung der Kolben verschiedenen Durchmessers Druckschwankungen, die für den Betrieb lästige Erscheinungen zut Folge haben. Die völlig dichte Kapselung des Kurbelraumes läßt sich teils wegen der Notwendigkeit eines leichten öffnens, teils wegen der Durchbrechungen für Kurbelwelle und Steuerungsteile nicht streng durchf'u'hren. Dadurch ist es möglich, daß durch die vorhandenen Fugen Schmieröl aus dem Kurbelraum herausgedrückt und andererseits staubreiche Luft hereingesaugt wird.Pressure-lifting machine. The subject matter of the invention relates to single acting Pneumatic machines with multiple expansion and with more than three cylinders work. If you encapsulate the crankcase in these closed engines, in this way, as a result of the movement of the pistons, different diameters arise in this space Fluctuations in pressure, which result in troublesome phenomena for operation. the completely tight encapsulation of the crankcase can partly because of the necessity easy opening, partly because of the openings for the crankshaft and control parts not to carry out strictly. This makes it possible that through the existing joints Lubricating oil is pushed out of the crankcase and, on the other hand, dust-rich air is sucked in will.
Erfindungsgemäß soll eine Pumpwirkung der Maschinenkolben dadurch ausgeschaltet werden, daß man sie derart versetzt zueinander anordnet, daß sich die durch die einzelnen Arbeitskolben hervorgerufenen Raumveränderungen des Kurbelgehäuses gegenseitig annähernd- aufheben und die Größe des. Gesamtkurbelraumes im wesentlichen konstant bleibt. Führt man beispielsweise eine Maschine mit 2 Hoch- und 2 Niederdruckkolben aus, so sollen die Kolben gleicher Stufe, also je die beiden Hoch- und die beiden Niederdruckkolben auf Kurbeln arbeiten, die um i8o° versetzt sind. Auf diese Weise wird erreicht, daß die Vergrößerung des Kurbelgehäuses durch den auswärts gehenden Kolben durch den gleichzeitig einwärts gehenden Kolben ausgeglichen wird. Wesentlich ist dieser Umstand besonders für die verhältnismäßig großen Niederdruckkolben. Wird eine vierzylindrige Maschine dreistufig, z. B'. mit je einem Hoch- und Mitteldruckzylinder und zwei Niederdruckzylindern ausgeführt, so ist ein völliger Ausgleich nicht möglich; eine wesentliche Besserung wird aber schon durch -die Versetzung der Niederdruckzylinder um i8o° geschaffen.According to the invention, a pumping action of the machine pistons is intended as a result be switched off that they are so offset from each other that the changes in space in the crankcase caused by the individual working pistons approximately cancel each other out and the size of the total crank space essentially remains constant. For example, if you run a machine with 2 high and 2 low-pressure pistons, the pistons should be of the same level, i.e. the two each The high-pressure and the two low-pressure pistons work on cranks that are offset by 180 ° are. In this way it is achieved that the enlargement of the crankcase by the outward moving piston is balanced by the inward moving piston will. This fact is particularly important for the relatively large low-pressure pistons. If a four-cylinder machine has three stages, e.g. B '. with one high and one medium pressure cylinder each and two low-pressure cylinders, a complete equalization is not possible; A significant improvement is achieved through the relocation of the low-pressure cylinder created around i8o °.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Maschine ist dreistufig und besitzt einen Hochdruckkolben a, einen Mitteldruckkolben b und zwei Niederdruckkolben cl, c2. Je die beiden Hoch- und Mitteldruckkolben und die beiden Niederdruckkolben liegen sich gegenüber und arbeiten auf einen gemeinsamen Kurbelzapfen. Die Bewegung der Niederdruckkolben hat keine Raumveränderung im Kurbelgehäuse zur Folge, und die durch die Bewegung der anderen Zylinder hervorgerufene ist von geringer Bedeutung. Würden anstatt dieser zwei Hochdruckzylinder verwendet, die Maschine also zweistufig betrieben, so wäre der Raumausgleich vollständig.An exemplary embodiment is shown in the drawing. The machine is three-stage and has a high pressure piston a, a medium pressure piston b and two low pressure pistons cl, c2. The two high and medium pressure pistons and the both low-pressure pistons are opposite each other and work on a common one Crank pin. The movement of the low-pressure pistons does not change the space in the crankcase and that caused by the movement of the other cylinders is from of little importance. Instead of these two high pressure cylinders would be used that If the machine is operated in two stages, the space compensation would be complete.
