Roll crank machines The invention relates to roll crank machines, in particular as motors, compressors, pumps and / or torque converters.

The principle of rolling machines stands between the principles of the piston engines and turbines. In cien known piston engines, the sliding paths are the seals are very long, e.g. piston rings, light strips or work slides. In the known turbines, the manufacturing costs are very high.

The invention is based on the objects of shortening glide paths, Sliding friction through. to replace full friction and / or lower manufacturing costs to enable.

These tasks are solved according to the invention by a roller (l), whose diameter is between full and half the housing bore diameter ctem cylindrical inner jacket of the housing bore rolls or runs past it and with the working slide (2), housing (3) and partition walls (4) two rooms forms, the volume of which is periodically changed between small content and work 5 content.

In order to allow the roller (1) to roll without constraint in the event of manufacturing tolerances, without, however, their sealing task, especially in the case of (3asedien, If the roller is drilled in the direction of the axis, the roller axis can be moved radially on the shaft (5) su store and through To support spring force and / or the sealing effect to use by centrifugal forces.

Mass balancing is achieved by counterweights or without additives by joining four or multiples of four units, whose 'alzen (l) run on a common 'light (5) and its two outer rollers the two inner ones Yvalzen opposite.

In order to be able to use roller crank machines as wasmotoren is at least a distribution piston (6) is required.

This also takes on the task of regulating the minimum pressure by spring force and the opening time by distributing cams (7). Limit pressure control there is silver regulation of the fuel supply.

By using the combustion chamber (8) or heat exchanger (9) CO-free exhaust gases are possible through complete combustion.

Steady flow with pumps and / or fluid drives is achieved by joining two units that run on a common TW'elle (b) and aeren rollers (1) are opposite one another.

The advantages achieved with the invention are lower manufacturing costs, short sliding paths, partly rolling friction instead of sliding friction, simple mass balancing, higher pressures in one stage compared to multi-cell compressors, for gas engines CO-free Exhaust gases, constant flow for fluid drives and through ring cross-sections are maximum pressures can be mastered with little material expenditure.

A basic unit of the invention and three exemplary embodiments are shown in simplified form in the drawings and are described in more detail below.

Pictures 1 to 4 show sections of a roller crawler machine unit. Meaning cell (5) milled on both sides carries crank eccentric (10) in a torque-transmitting manner Link. To avoid compulsion, crank eccentrics can be moved axially and radially and spring-loaded in the direction of the roller axis. Rotatable on crank eccentrics italze (l) rolls on a cooled cylindrical housing (3). Centrifugal forces of the roller increase the lighting effect between the seam and the housing. The subdivision of the work area in two chambers takes place through housing (3), partitions (4), 'alze (l) and working slide, which slides spring-loaded in the housing groove with seal. The lateral chamber seal takes place by means of spring-supported sealing ringsill). Mass balancing of the roller is done by Counterweight reached. The best diameter ratio of hole and roller lies by 7 to 6, it is to be adapted to the scope of duties. Impeccable work is guaranteed through usual lubrication, solid-free working medium and adequate cooling.

Figures 5 to 7 show a four-part roller crank machine with a full Compensation as gas engine with two-part compressor and two-part motor part, Combustion chamber (8), distribution piston (6), distribution cam (7), distribution shaft with drive and Piping system. Figure 6 shows typical compressor and Figure 7 typical Gas engine in section The workflow after starting is based on suction Via air filter, compression in the compressor part and outflow via backflow preventer After the combustion chamber (8), the working air is heated up by combustion and routing of the working gas to the distribution piston (6), work in the engine part by releasing it on exhausting and releasing the relaxed CO-free exhaust gases. At part load Fresh air is drawn in.

Figure 8 shows a schematic section of a one-part or multi-part Roll crank machine as a gas engine with heat exchanger () and closed system. Of the The workflow after starting is structured as follows: Compaction, heating in heat exchanger (), expansion in the engine with a drop in temperature and pressure and thus Cooling, which is supported by the cooled housing and compressing the Working air etc. Nine internal cooling is possible through holes. Fresh air supply fi: l for start and for volume loss compensation through valve (12). Relaxing on External pressure is not possible at part load, therefore less due to higher compression work Remaining performance against full load. The advantages are the clean engine and the fact that it is not necessary the filter work. When using faster heat exchangers, it can also be used as a vehicle engine possible.

Figure 9 shows an application example of a fluid drive Roll crank machine base for z. B. agricultural machine with closed System.

The two-part pump (13) driven by the motor via a gearbox supplies it with steady flow four two-part drive motors (14) with working fluid via pressure and return lines. Control is through clutch and brake valve (15) possible. The advantage is the saving of mechanical differential gears. To the To lock compensation, additional lines and valves are required.
