Den Gegenstand der Erfindung bildet eineThe subject of the invention is a

Verbundexplosionskraftmaschine mit zwei konzentrisch angeordneten Expansionsräumen, bei welcher in den äußeren Expansionsraum Wasser eingeführt wird.Compound explosion engine with two concentrically arranged expansion chambers, in which water is introduced into the outer expansion space.

Die Erfindung besteht im wesentlichen darin, daß im Innern des äußeren Expansionsraumes ein fester und ein mit dem Kolben sich bewegender Metallring angeordnet sind, welche ίο mit Rippen ausgerüstet sind. Diese Ringe und Rippen nehmen die Wärme der entzündeten Gase auf und geben die Wärme an in fein zerstäubtem Zustande in dem äußeren Expansionsraum eingeführtes Wasser wieder ab, welches über die Rippen und Ringe rieselt, um Dampf zu erzeugen und ein Gasdampfgemisch zu bilden.The invention consists essentially in that inside the outer expansion space a fixed metal ring and a metal ring moving with the piston are arranged, which ίο are equipped with ribs. These rings and ribs absorb the heat from the ignited gases and give off the heat in finely atomized water introduced into the outer expansion space which trickles over the ribs and rings to generate steam and a gas-vapor mixture to build.

In den Zylinder der Maschine ragt ein rohrartiger Ansatz 2 des Deckels hinein. In das Innere dieses Ansatzes mündet eine Leitung i, durch welche das Ladegemisch eingeführt wird. Der Hohlraum des rohrartigen Körpers 2 ist mit einem Ventil 5 versehen, das sich nach dem Raum 6, der von der Wandung eines hohlen Kolbens 9 umschlossen wird, öffnen kann. Der Hohlraum 6 steht mit einem Kanal 2 ^a und dem Zündraum 7 in Verbindung, welcher seitlich in einen Kanal 8 ausläuft, der an der Außenwand des Körpers 2 durch Öffnung 13 mündet. In der Wandung des hohlen Kolbens befindet sich ein Schlitz 14, der sich bei der obersten Stellung des Kolbens 9 mit der Öffnung 13 deckt, so daß zeitweilig zwischen dem Raum 8 und dem den oberen Kolbenteil umgebenden Raum 11 eine Verbindung hergestellt wird. Der Raum 11 ist mit einem Kanal 15 verbunden, der zu einem Drehschieber 16 führt, an welchem sich ein Auspuffkanal 22 und ein Überströmungskanal 17 abzweigen, von denen dieser in den Zylinderraum unterhalb des Kolbens 9 führt. Der Kolben ist, wie üblich, mit einer Kolbenstange 10 verbunden.A tubular extension 2 of the cover protrudes into the cylinder of the machine. A line i, through which the charging mixture is introduced, opens into the interior of this approach. The cavity of the tubular body 2 is provided with a valve 5 which can open towards the space 6 which is enclosed by the wall of a hollow piston 9. The cavity 6 is provided with a channel ^2a and the ignition chamber 7 in combination, which terminates in a channel 8 at the side which opens at the outer wall of the body 2 through the opening. 13 In the wall of the hollow piston there is a slot 14 which, in the uppermost position of the piston 9, covers the opening 13, so that a connection is temporarily established between the space 8 and the space 11 surrounding the upper piston part. The space 11 is connected to a channel 15 which leads to a rotary valve 16, at which an exhaust duct 22 and an overflow duct 17 branch off, from which it leads into the cylinder space below the piston 9. As usual, the piston is connected to a piston rod 10.

Die Wirkungsweise der Maschine ist im wesentlichen folgende:The principle of operation of the machine is as follows:

Befindet sich der Kolben 9 in der oberen Totlage (vergl. Fig. 1 und 2) und beginnt seinen Hub nach unten, so saugt er durch das Ventil 5 das Explosionsgemisch ans dem Raum 2 an. Bei diesem Hub steht der Raum 12If the piston 9 is in the upper dead position (see FIGS. 1 and 2) and begins its stroke downwards, it sucks the explosive mixture through the valve 5 Room 2. Room 12 is at this hub

Claims

with the exhaust 22 in connection (Fig. 1). During the next upward stroke, the sucked-in mixture is compressed in the space 6 and partially pushed into the annular space 11 through the channel 8 and the slots 13 and 14 as soon as these coincide (approximately at the end of the stroke). Here, the rotary valve assumes the position of FIG. 7 and the burned gases are sucked back into the space 12. Now the ignition takes place, which is communicated to both the space 6 and the space 11, so that the piston under the pressure of the exploded gases, which on the outer ring surface of the piston and at the same time on the inner, the space 6 delimiting surface of the piston acts, goes down, the burned gases from the space 12 through channel 17 in the line 22 are forced. In the fourth cycle (see. Fig. 9 and 9 a), in which the piston, from the lower dead position ^ in the upper dead position α, the rotary valve 16 is first controlled so that the channel 15 with the channel 17, so the Annular space 11 comes into communication with the lower cylinder space. In this position of the rotary valve, the steam gas mixture located in the space 11 reaches the space 12 and. causes the piston to rise against the counter-pressure prevailing in space 6, which is generated by the compression of the burnt gases in this space. This counter pressure increases as the crank of the machine moves from position b to position c (FIG. 9 a). In position c of the crank, the rotary valve is reversed, so that the channel 17 is shut off, while the channel 15 is brought into connection with the exhaust 22 until the crank has reached the top dead center α. Here, the gases compressed in space 6 flow through slots 13 and 14 and through channel 15 into the open, so that fresh mixture can be sucked into space 6 during the next stroke. The gases remaining in the space 12 then escape during the next first stroke through the rotary valve 16, which now again assumes the position (FIG. 7), whereupon the game begins again. The overflow cross-section of the rotary valve 16 is expanded at χ in order to achieve an exact setting of the valve adapted to the mode of operation. According to the invention, metal inserts 19 and 20, which have projections or ribs, are in the annular space 11 of the cylinder. are provided, one of which is attached to the wall of the cylinder, suitably insulated from the cylinder by an asbestos jacket, and another is attached to the piston 9. Each rib of one insert engages in the space between two ribs of the other insert. A shower pipe 21 is arranged above the inserts at the upper end of the annular space 11, through which a fine spray of water is directed onto the inserts 19 and 20 and their ribs. Inserts 19 and 20. absorb the heat released during the ignition of the gas-air mixture as well as the heat of the gases passing from the room 8 into the room 11 and finally the heat that is diverted from the room 6 and radiates to the outside and share it with the trickling water, which evaporates. The steam mixes with the burnt gases passing into the annular space 11, causes a strong increase in pressure and in the fourth cycle enables the counterpressure that occurs in space 6 as a result of the compression of the burnt gases to be overcome. The diagram in FIG. 11 shows the pressure profile of the sucked in and ignited gas-air mixture within the space 6. The diagram in FIG. 12 shows the pressure profile of the gas-vapor mixture in space 11 and the diagram in FIG. 13 shows the pressure profile of the gas-vapor mixture in space 12 during a reciprocation of the piston.
