Definitions
- the invention relates to a compressor, comprising a liquid or liquid column which can be displaced in the piston chamber and acts as a piston.
- the liquid used in such compressors is preferably an ionic liquid, since, on the one hand, it does not dissolve in the medium to be compressed and, on the other hand, it can be separated without residue from the medium to be compressed.
- other liquids may also be used, for example heavy-boiling hydraulic oils, vacuum oils or other low-boiling liquids with a low medium solution.
- Hydraulic fluid itself. If it can not be achieved by them sufficient cooling effect, usually an external cooling, for example in the form of a cooling jacket, realized in the rule.
- Object of the present invention is to provide a generic compressor in which the cooling performance or effect, in particular in the region of top dead center improves and thereby the efficiency of the compressor can be increased.
- a generic compressor comprising a displaceable in the piston chamber, acting as a piston liquid, proposed, which is characterized in that a displaceable with her piston dummy is arranged in the liquid.
- the piston dummy is designed in such a way that when the top dead center is reached it causes an acceleration of the fluid in the annular gap defined by it and the piston chamber wall,
- the underside of the piston dummies is designed such that the liquid in the
- the liquid is at least partially an ionic liquid.
- Figures 1 to 3 show a lateral, not to scale sectional view through a possible embodiment of the compressor according to the invention, wherein Figure 1 shows the situation at the beginning of a compression stroke, Figure 2 shows the situation at the end of a compression stroke and Figure 3 shows the situation during the intake stroke ,
- the compressor according to the invention has a piston 1, which defines a piston chamber 2, on.
- a liquid column forming liquid 3 which is preferably an ionic liquid, is arranged.
- a hydraulic piston 4 By means of suitable measures - represented in FIGS. 1 to 3 by a hydraulic piston 4 - the liquid column 3 is moved up and down within the piston chamber 2.
- At least one intake valve 6 and at least one pressure valve 7 are also provided on the cylinder head.
- a one-piece or multi-piece piston dummy 5 is now arranged inside the liquid 3.
- This piston dummy 5 is surrounded by the liquid 3 so that possibly provided seals of the hydraulic piston 4 are in contact with the fluid 3 at all times.
- the piston dummy 5 advantageously has at least approximately the shape of the cylinder or piston chamber 2.
- the piston chamber 2 preferably has a flow and / or cooling technology optimized inner contour.
- the aforementioned suction 6 and pressure valves 7 are arranged in an advantageous manner such that they support the cooling process.
- the underside of the piston dumbbell 5 is preferably designed such that the liquid 3 is held or accelerated in the area of the piston dummy underside.
- piston dumbbell 5 remains the top layer of the liquid 3 on the piston dummy 5. This effect occurs especially in ionic liquids, since the accelerated amount of liquid can no longer dip into the liquid surface. However, this behavior is desirable because in the subsequent compression stroke exactly this (hot) amount of liquid via the pressure valve 7 from the piston 1 and piston chamber 2 is discharged.
- the shape of the piston dumbbell 5 is determined substantially by the shape of the piston interior 2 in its upper region. Basically, however, a variety of different piston dummy forms can be realized in practice.
