Description

Crossbars 4 existing 3 component 9 and are on the outer circumferential surfaces 14 of the respective double cylinder unit 1.2 attached The cooling lines should be made of copper, in order to prevent bending, in the interior Have a compressed air hose that is removed before the cooling system is started up. The so arranged cooling lines 15 are to be embedded in cast aluminum, the space between the component 9 and the outer circumferential surfaces 14 as far as possible. For better heat dissipation Additional ribs can be provided on this cast aluminum body for cooling.

As in the left half in FIG. 1 is shown serves the inner tube 11 of the coolant supply and discharge line 10 at the same time as the axis of the output side of the internal combustion engine, on which axis the gear 20 is mounted with the aid of roller bearings 21 In the area of these roller bearings 21, small openings can be provided in the extension 16 of the axis through which the coolant to lubricate the roller bearings 21 can escape.

With 23 are schematically in F i g. I designates two labyrinth seals that are connected to the outer tube 12 of the coolant supply and derivative 10 work together. These . I labyrinth seals 23 are attached in front of the gears arranges, d. H. between the gears and the respective double cylinder unit 1,2.

In Figure 2, a section is shown in a perspective view of the two opposite Double cylinder units 1, 2 includes. The connection between these is shown in FIG. 1 schematically indicated Component 9 is provided. The component 9 has a central opening 30. Furthermore, FIG. 2 the course of the cooling lines 15 can be seen on the outer cylinder jacket surfaces 14 of the coolant supply and discharge line 10. The coolant supply and derivation takes place via the in F i g. Double tube arrangement 31 indicated in FIG.

Internal combustion engine according to claim 1, characterized in treatment in each orbital state of the double cylinder, that between which the transverse webs (4) units of the reciprocating internal combustion engine. and disks (3) having component (9) and the An embodiment of the invention is next Outer jacket surfaces (14) of the respective double cylinder explained in more detail with reference to the drawing. It shows Lindner unit (1, 2) 25 F i g running in a serpentine manner. 1 shows a schematic overall view of a lifting cooling line (15), the twin-piston internal combustion engine according to the invention, and

In Fig. 1 are two double cylinder units with 1 and 2 schematically shown These two double cylinder units 1, 2 are opposite one another. Fixed with The invention relates to a reciprocating piston internal combustion engine - this is connected to a disk assembly that is attached to machine, in particular a two-stroke internal combustion engine 35 carries transverse webs 4 on its circumferential surface, the slots 5 machine, with four circumferential piston-cylinder arrangement limit. Two connected to the transverse webs 4 openings, according to the preamble of claim 1. Disks 3 of the disk arrangement form a component 9, Such a reciprocating internal combustion engine is provided between the double cylinder units 1, 2 the DE-OS 25 35 542 known A training hen is. In Fig. 1 with 6 are two fixed mixtures of these Reciprocating internal combustion engine is shown in DE-OS 40 inlet pipes through the slots 5 in the 29 08 511 specified. Due to the orbital movement, the disk arrangement and its cylinder side run from it Pistons and cylinders there is a circumferential opposite the ends of inlet openings on the cylinders over-screed mixing supply device intended to consume. With 7 exhaust gas outlet pipes are designated, which is dig and cumbersome, the circumferential movement of the cylinder interior of the respective cylinder 45 double cylinder units 1, 2 open, disadvantageously to the durability of this device. More expedient. In the latter known case, these exhaust gas outlet pipes 7 are in the housing of the wise Doppelzylindereinheilen in addition to a Glyce internal combustion engine with the formation of a labyrinth dichrin operated cooling system also uses a cooling device, which is shown schematically in FIG. 1 indicated one made of water and an oily additive and is denoted by 8. With a total of 10 is the Kühiden Emulsion. Difficulties arise in this case 50 medium supply and drainage referred to the cooling with regard to the laying of the outer cylinder surface on the cylinder outer surface. These coolant jacket surfaces provided cooling lines, since a gel supply and discharge line 10 is shared by a double pipe continuous axis for two opposing order formed, which consists of an inner tube 11 and one overlying double cylinder units is present. Outer tube 12 is made. Between the outer tube 12 and The invention is based on the object that the inner tube 11 forms an annular intermediate arrangement of the pipes carrying the mixture at an intermediate space 13. As in FIG. 1 schematically by arrows Reciprocating piston engine of the generic type indicated, the inner tube 11 is used for the coolant supply type to the effect that the durability device and the annular space 13 between of the tubes independently of the orbital movement of the inner tube 11 from the outer tube 12 as return line double cylinder units remains guaranteed for the coolant. Around the cylinder outer jacket According to the invention, this object is achieved with the areas in, of which one with 14 in FIG. 1 is designated, characterizing part of claim 1 specified run schematically indicated, serpentine Features solved. running cooling lines 15. The serpentine As a result of the measures according to the invention, running cooling lines 15 are arranged in such a way that is enough that despite the orbital movement of the double cylinder 65, the coolant circulates as evenly as possible around the the units a fixed arrangement of the mixed cylinder outer lateral surfaces 14 is achieved. The cooling pipes are possible, the disks direct lines 15 are, as in FIG. 1 schematically in time for the branching of the mixture pipes to the one shown, between the one from the disks 3 and the
