Description

Abdichtungsvorrichtung für Kraftmaschinen mit im umlaufenden Gehäuse verschiebbaren Kolben und sichelförmigem Arbeitsraum. Bei Kraftmaschinen mit umlaufendem Gehäuse und radial in diesem verschiebbaren Kolben ist es besonders schwierig, die unter Wirkung der Fliehkraft stehenden Kolben in einfacher Weise gegen die feststehende, im Innern des Gehäuses gelagerte Trommel zur Abdichtung anzudrücken.Sealing device for power machines with a rotating housing sliding piston and sickle-shaped working space. In power machines with rotating Housing and radially in this displaceable piston it is particularly difficult, the under the effect of centrifugal force piston in a simple way against the stationary, Press the drum mounted inside the housing to seal it.

Die vorliegende Erfindung behebt diese Schwierigkeiten und gibt zugleich die Möglichkeit einer Regelung der Umlaufzahl der Maschine.The present invention overcomes these difficulties and provides the possibility of regulating the number of revolutions of the machine.

Die Erfindung ist in den Abb. i und 2 veranschaulicht. In Abb. i ist die Maschine im Längsschnitt dargestellt. In Abb.2 ist die Maschine in der rechten Hälfte quer geschnitten gezeichnet (Schnitt A-B, Abb. i). .Inder anderen Hälfte ist die Kopfansicht mit abgenommenem Seitendeckel dargestellt, und zwar in Pfeilrichtung C gesehen.The invention is illustrated in Figs. In Fig. I is the machine shown in longitudinal section. In Fig 2 the machine is in the right Half drawn cross-section (section A-B, Fig. I). .In the other half the head view is shown with the side cover removed, in the direction of the arrow C seen.

Im Kolbengehäuse a sind in seitlich eingedrehten Hohlräumen q Ringe b angeordnet. Für die Kolben e sind entsprechende Schlitze d im Gehäuse a vorgesehen. Die ebenfalls in Schlitzen sich bewegenden Querstücke c tragen 'an einer dem Kolben e zugekehrten Seite eine Feder f. Die zum Gehäuse exzentrisch liegende Trommel besteht aus dem Einströmzylinder ä und dem Auspuffzylinder h.. Tritt das gespannte Gas durch den Einströmkanal i. des Einströmzylinders g in den Arbeitsraum k, so wird das Kolbengehäuse zur Drehung gebracht. Durch die ebenfalls mitlaufenden Ringe b, Querstücke c und Federn f werden die Kolben e an die Trommel g, h abdichtend angedrückt, sie bewegen sich also entsprechend der Exzentrizität in den Schlitzen d auf und ab. Bei Überschreitung der der Spannung der Feder f zugrunde gelegten Umdrehungszahl der Maschine wird die Fliehkraft der Kolben e so groß, daß sie sich entgegen der Kraft der Feder f von der Tromrnel g, h. abheben. Die Arbeitsräume k sind dann miteinander verbunden, und das Treibmittel Medium entweicht durch die Auspuffschlitze in. Es wird hier durch in einfachster Weise eine Regelung' der Umlaufzahl herbeigeführt, die abhängig ist von der Einstellung der Federkraft, die auf die Kolben wirkt.In the piston housing a, rings b are arranged in laterally screwed-in cavities q. Corresponding slots d are provided in the housing a for the pistons e. The cross pieces c, which also move in slots, carry a spring f on a side facing the piston e. The drum, which is eccentric to the housing, consists of the inflow cylinder ä and the exhaust cylinder h .. If the tensioned gas passes through the inflow channel i. of the inflow cylinder g into the working space k, the piston housing is made to rotate. The pistons e are pressed against the drum g, h in a sealing manner by the rings b, crosspieces c and springs f , which also move along with them, so they move up and down in the slots d according to the eccentricity. If the number of revolutions of the machine on which the tension of the spring f is based is exceeded, the centrifugal force of the pistons e becomes so great that they move against the force of the spring f from the drum g, h. lift up. The working spaces k are then connected to one another, and the propellant medium escapes through the exhaust ports. Here, a regulation of the number of revolutions is brought about in the simplest way, which is dependent on the setting of the spring force acting on the piston.

Die Änderung der Umdrehungsrichtung geschieht zweckmäßig durch ein Handrad o, das mit dem Ausströmzylinder h verbunden ist und das um ein bestimmtes Maß nach der einen Seite gedreht wird, während gleichzeitig der mit dem Einströmzylinder g verbundene Zeiger P, nach der anderen Seite gedreht wird. Das gespannte Gas tritt jetzt in den Sichelraum d; leistet Arbeit und entweicht aus dem Raum k durch die Schlitze nz des Auspuffzylinders h. Um die Trommel g, h vor starkem Verschleiß zu schützen, sind zwei aus hartem -Werkstoff hergestellte Laufringe p im Trommelumfang leicht drehbar gelagert. Die Kolben e nehmen durch den Druck der Federn 'f die beiden Laufringe p mit, wodurch ein vorzeitiger Verschleiß der stillstehenden Trommel ä, h vermieden wird.The change in the direction of rotation is expediently done by a Handwheel o, which is connected to the discharge cylinder h and that around a certain Measure is turned to one side, while at the same time with the inlet cylinder g connected pointer P, is rotated to the other side. The tensioned gas kicks in now in the sickle room d; does work and escapes from space k through the Slots nz of exhaust cylinder h. To the drum g, h from excessive wear protect, there are two races p made of hard material around the drum circumference easily rotatable. The pistons e take the two under the pressure of the springs' f Races p with, as a result of which premature wear of the stationary drum ä, h is avoided.
