Gegenstand der Erfindung ist eine Explosionskraftmaschine mit sternförmig angeordneten Zylindern, bei welcher die Kolbenstangen aller Zylinder an einer gemeinsamen Scheibe angreifen, welche mit einem Kreuzkopf verbunden ist. Dieser Kreuzkopf bewegt sich in einer Führung, welche ihrerseits wiederum senkrecht zu der Bewegungsrichtung des Kreuzkopfes in Lagern eine Längsverschiebung ausführt. Die mit dem Kreuzkopf verbundene Scheibe sitzt dabei auf der Kurbel der Hauptwelle der Maschine, und es wird daher bei ihrer Bewegung erreicht, daß sie sich nicht um sich selbst drehen kann, sondern daß ihre einzelnen Punkte Kreise beschreiben, deren Radien demjenigen der Kurbel entsprechen. Mit der Kurbelwelle der Maschine ist gleichzeitig noch eine Zündvorrichtung verbunden, auf der die einzelnen Kontakte für die Zylinder derart angeordnet sind, daß während einer Umdrehung stets nur die Hälfte der Stromkreise geschlossen wird, indem in der Reihenfolge der Zylinder stets einer übersprungen und erst bei jeder zweiten Umdrehung die Zündung in jedem Zylinder stattfindet.The invention relates to an explosion engine with a star-shaped arrangement Cylinders, in which the piston rods of all cylinders on a common Attack the disc, which is connected to a crosshead. This crosshead moves in a guide, which in turn is perpendicular to the direction of movement of the cross head in bearings carries out a longitudinal displacement. The one with the cross head connected disc sits on the crank of the main shaft of the machine, and it it is therefore achieved during its movement that it cannot turn around itself, but that their individual points describe circles, the radii of which correspond to those of the Crank match. There is also an ignition device at the same time as the crankshaft of the machine connected, on which the individual contacts for the cylinder are arranged in such a way are that only half of the circuits are closed during one revolution is skipped by always skipping one in the order of the cylinders and only at each second turn the ignition takes place in each cylinder.

Die Zeichnung stellt ein Ausführungsbeispiel dieser Einrichtung in Fig. 1 in einem Querschnitt, Fig. 2 in teilweisem Längsschnitt dar. Fig. 3 zeigt die Anordnung des Kommutators für die Stromzuführung zu den Zündvorrichtungen und Fig. 4 die gemeinsame Platte, an der die Kolbenstangen befestigt sind.The drawing shows an embodiment of this device in FIG. 1 in one Cross-section, Fig. 2 in partial longitudinal section. Fig. 3 shows the arrangement of the commutator for the power supply to the ignition devices and FIG. 4 the common plate to which the piston rods are attached are.

Das Gehäuse der Maschine wird von einem kastenförmigen Ring A gebildet, der mit einer Anzahl radial stehender, nach dem Mittelpunkt des Ringes offener Zylinder versehen ist. In den Zylindern bewegen sich Kolben B, deren Kolbenstangen C mittels Zapfen C¹ an der gemeinsamen Scheibe D angreifen. In dem dargestellten Ausführungsbeispiele sind 15 Zylinder angenommen, die an die Ringleitung A¹² angeschlossen sind. Aus derselben tritt das Kraftmittel durch den Krümmer ^¹⁰ in die Verbrennungskammer .A⁸, wobei das Einlaßventil A⁹ die Zuführung entweder selbsttätig oder zwangläufig regelt. Die Entzündung des Gemisches erfolgt durch die Zündkerze A^li und der Austritt der Verbrennungsprodukte in den Raum A^, wenn derselbe durch das Auspuffventil R freigegeben wird. Der Raum A⁵ steht mit dem Raum A⁶ in Verbindung, an den die gemeinsame Auspuffleitung A⁷ angeschlossen ist. Die Kühlung der Zylinder geschieht durch Zuführung von Kühlflüssigkeit durch den Stutzen P¹ (Fig. 2) in den Zylindermantel A^w. Nachdem das Kühlwasser den ganzen Ring durchflossen hat, verläßt es denselben bei Q.¹; die Scheidewand R¹ verhindert dabei eine direkte Verbindung der Zu- und Ausflußöffnungen. Die Kurbelwelle E der Maschine, welche zentrisch zu dem Ring A gelagert ist, besitzt einen Kurbelzapfen, der seinerseits zentrisch die Scheibe D trägt. Die letztere ist zweiteilig und mit dem Kreuzkopf V¹ mittels Schrauben o. dgl. starr verbunden (Fig. 1). Der Kreuzkopf F¹ läuft gleichzeitig in der Führung V, die ihrerseits wieder mit Stangen W versehen ist, die in Hülsen X senkrecht zur Bewegungsrichtung des Kreuzkopfes gleiten. DieThe housing of the machine is formed by a box-shaped ring A which is provided with a number of radially standing cylinders that are open towards the center of the ring. Pistons B move in the cylinders, and their piston rods C engage the common disk D by means of pin C ¹ . In the exemplary embodiment shown, 15 cylinders are assumed which are connected to the ring line A ¹² . From the same the power medium passes through the manifold ^ ¹⁰ into the combustion chamber .A ⁸ , the inlet valve A ^{9 regulating} the supply either automatically or positively. The mixture is ignited by the spark plug A ^li and the combustion products exit into space A ^ when the same is released through the exhaust valve R. The space A ⁵ is connected to the space A ⁶ , to which the common exhaust line A ^{7 is} connected. The cylinder is cooled by supplying cooling liquid through the connector P ¹ (FIG. 2) into the cylinder jacket A ^w . After the cooling water has flowed through the whole ring, it leaves the same at Q. ¹ ; the partition R ¹ prevents a direct connection of the inlet and outlet openings. The crankshaft E of the machine, which is mounted centrally to the ring A , has a crank pin, which in turn carries the disc D centrally. The latter is in two parts and rigidly connected to the cross head V ¹ by means of screws or the like (FIG. 1). The cross head F ¹ runs at the same time in the guide V, which in turn is again provided with rods W which slide in sleeves X perpendicular to the direction of movement of the cross head. the

Claims

Disk D can therefore only move parallel to itself, with its individual points describing circles whose radii are equal to the length of the crank. The cylinder ring A is closed by two plates Az and A *, which accommodate the bearings for the crankshaft and of which one can be designed as a base plate when the machine is arranged horizontally. ίο One end of the crankshaft is provided with a bevel gear of a reversing gear or the like, while the other end is drilled out in order to be able to take up the control wilt: Af_auf. The crankshaft is keyed by the gear H, which is engaged by the wheels / through which the movement is transmitted to the inner ring gear of the wheel / to which the control shaft is connected. As a result, the latter "only rotates at half the speed of the main shaft. The non-circular disks N, the number of which corresponds to that of the cylinders, are fastened to the control shaft and, as they rotate, move the levers O provided with rollers P and rotating around bolts Q. The hood 5 surrounds the parts of the outlet control located outside the housing and is closed off from the outside by a cover T. The end of the control shaft carries the commutator U, which consists of an insulated disc into which a conductive piece U1 The current collectors U2 for the individual cylinders slide on the commutator and are arranged in such a way that the current to two cylinders is drawn simultaneously through the piece U1.The individual current collectors U2 are in conductive connection with the spark plugs Au that the stream is not closed in the order of the cylinders, namely I, 2, 3, 4 etc., but s o that first the circuits for cylinders i, 3, 5, 7 etc. are closed and after the contact piece rotating at half the speed of the crankshaft has completed half of the way, the circuits for cylinders 2, 4, 6 , 8 etc. are closed. This arrangement ensures that ignition takes place in each cylinder with every second revolution. The number of cylinders is expediently odd. The machine can be arranged so that the shaft is vertical or horizontal; the shaft can also carry several cylinders. Instead of the reversing gear, the machine itself can also be reversed in that the control shaft is adjusted in its guides so that the current for the ignition takes place in the reverse order. Godfather τ-An Proverbs:

1. Explosive engine with cylinders arranged in a star shape, characterized in that the piston rods of the cylinders act on a common disc (D) which is rigidly connected to a cross head (V ¹ ) , which is in a by rods (W) in sleeves (X) running frame.

2. Explosive engine according to claim ι, characterized in that The circuit for the cylinders (1, 3, 5, 7 etc.) is closed alternately during one revolution of the crankshaft, while at the second revolution of the crankshaft the circuit for the cylinders (2, 4, 6, 8, etc.) is closed, so that an ignition in each cylinder for every two revolutions of the crankshaft takes place.
