- Liquid can be used. However, it is also possible to use liquids with a low vapor pressure or liquids with a low gas solubility. Such liquids have in common that they do not dissolve in the medium and are separated from the medium residue-free, so that the compressed medium has a high purity.
- a pistonless compressor for gaseous media is known from US Pat. No. 6,652,243 B2.
- the operating fluid is in the compressor cylinders with a designed as a hydraulic pump displacement machine in connection, wherein for controlling the inflow and outflow of the
- Operating fluid is provided a control valve, which is controlled in response to the liquid level of the operating fluid in the compressor cylinders, which is detected by means of electronic displacement measuring systems.
- the compressor cylinders are preferably arranged vertically in order to support the outflow of operating fluid from the displacer cylinder by gravity.
- the liquid column of the working fluid can not be accelerated above the acceleration of gravity, so that the cycle speed of the compressor is limited by the gravitational acceleration. Due to this high Cycle time and long cycle times, such compressors have a high flow rate pulsation of the flow of the compressed medium. If a uniform flow of compressed medium is required, for example, for refueling of vehicles, a buffer is required, in which promote the compressor cylinder.

- the separating device communicates with the inlet line by means of a return line, wherein a valve device is arranged in the return line.
- the valve device can be designed, for example, as a check valve opening in the direction of the inlet line.
- the valve device as a switchable Trap valve train. With such valve devices, it is possible in a simple manner to continuously or cyclically recycle operating fluid separated from the outlet line by means of the separating device into the inlet line, whereby the compressor can be operated in a simple manner with a constant amount of operating fluid.
- a container which communicates with the piston engine by means of a leakage line. The occurring during operation of the piston engine leakage amount of operating fluid can be supplied to a container in a simple manner.
- a feed pump which is the input side with the container and the output side with the inlet line of the compressor in communication.
- the amount of leakage of the piston engine to operating fluid in the container can thereby be easily supplied to the inlet side of the compressor, whereby the compressor with a constant amount of operating fluid is operable.
- the feed pump can be operated continuously or cyclically.
- the feed pump is controllable according to an embodiment of the invention as a function of the amount of operating fluid in the container. This makes it possible in a simple manner to keep the amount of operating fluid in the compressor constant in order to achieve a safe operation of the compressor.
- the container is provided with a level measuring system, wherein the feed pump is controllable in dependence on the level measuring system.
- the feed pump is controllable in dependence on the level measuring system.
- the piston engine can be designed as a radial piston engine according to an embodiment of the invention.
- a flow rate can be achieved with low construction costs and space requirements compacted medium can be achieved with low flow rate pulsation.
- radial piston machines have a long service life, whereby a long service life can be achieved for the compressor.
- the piston engine can also be designed as an axial piston according to a further embodiment of the invention.
- an axial piston machine in which each cylinder chamber communicates with a compressor cylinder, a flow of compressed medium with low flow rate pulsation with low construction costs and space requirements and a long service life of the compressor can also be achieved.
- the compressor 1 has a displacement machine which is designed as a piston engine 2, for example a radial piston engine, which is provided with a plurality of cylinder chambers 2a, 2b, 2c, 2d, 2e.
- a piston engine 2 for example a radial piston engine
- the compressor cylinders 4 a, 4 b, 4 c, 4 d, 4 e is formed as an ionic liquid operating fluid 5, which is movable by means of the piston engine 2.
- the compressor cylinders 4a, 4b, 4c, 4d, 4e are on the input side via a respective
- Inlet valve 6a, 6b, 6c, 6d, 6e with an inlet line 6 for medium to be compressed, for example, natural gas or hydrogen in combination.
- the inlet line 6 can be assigned to increase the input pressure and thus the output power of a supercharger.
- the compressor cylinders 4a, 4b, 4c, 4d, 4e are connected via an outlet valve 7a, 7b, 7c, 7d, 7e to an outlet line 7.
- a separating device 8 designed, for example, as a liquid separator is arranged, by means of which the operating liquid 5 conveyed into the outlet line 7 by the compressor cylinders 4a, 4b, 4c, 4d, 4e can be separated off.
- the separating device 8 is connected to a return line 9, which is connected to the inlet line 6.
- a valve device 10 is arranged in the return line 9, operating fluid 5 separated from the outlet line 7 by the separating device 8 can be conveyed back to the inlet line 6. This makes it possible in a simple manner to keep the amount of operating fluid 5 in the compressor cylinders 4a, 4b, 4c, 4d, 4e constant.
- the piston engine 2 is connected to a leakage line 1 1 in connection, which is guided to a container 12. The occurring during operation of the piston engine 2
- Leakage amount of operating fluid 5 flows through the leakage line 11 to the container 12.
- the container 12 is provided with a level measuring system 15.
- a feed pump 13 which is connected on the input side to the container 12 and the output side is connected via a feed line 14 to the inlet line 6, via the leakage line 11 into the container 12 flowing leakage amount
- Operating fluid 5 of the piston engine 2 are conveyed to the inlet line 6.
- the feed pump 13 can in this case be operated in dependence on the level measuring system 15. This makes it possible in a simple manner, the amount of operating fluid 5 in the compressor cylinders 4a, 4b, 4c, 4d, 4e to keep constant.
- the operating fluid in the compressor cylinders 4 a, 4 b, 4 c, 4 d, 4 e is moved with almost the gravitational acceleration such that in the displacement cylinders 4 a, 4 b, 4 c, 4 d, 4 e medium to be compressed from the Inlet line 6 sucked and compressed medium is conveyed into the outlet 7.
- the compressor cylinders 4a, 4b, 4c, 4d, 4e in this case convey with a low cycle time and thus high cycle speed in succession into the outlet line 7, whereby a flow of compressed medium with low flow rate pulsation is achieved.
- the amount of operating fluid 5 in the displacement cylinders 4a, 4b, 4c, 4d, 4e is in this case dimensioned such that constantly over-delivery of operating fluid 5 into the outlet conduit 7 occurs. This achieves that medium drawn in from the inlet line 6 is completely compressed and conveyed into the outlet line 7, as a result of which dead volume and thus delivery losses of the medium to be compressed are reduced.
- the operating fluid 5 conveyed by the compressor 1 into the outlet line 7 is separated from the compressed medium by means of the separating device 8.
- the separated quantity of operating fluid 5 can be fed back to the inlet line 6 continuously or cyclically, thus keeping the amount of operating fluid in the compressor cylinders 4a, 4b, 4c, 4d, 4e constant.
- the resulting leakage amount of operating fluid 5 is measured in the container 12 and the feed pump 13, for example, frequency-controlled, depending on the measured amount of leakage controlled at operating fluid 5 in the container 12, whereby as leakage of the piston engine 2 resulting operating fluid 5 is conveyed from the container 12 to the inlet line 6.
- the compressor 1 according to the invention is suitable due to the low cycle times, the high cycle speed and the low flow rate pulsations for consumers, which require a constant and uniform flow rate of compressed medium, for example for refueling vehicles.
- Piston machine 2 by means of the feed pump 13 to the inlet line 6 of the compressor 1 can be ensured in a simple manner, a sufficient amount of operating fluid 5 in the compressor cylinders 4a, 4b, 4c, 4d, 4e.
- To control the feed pump 13 in this case only a simply constructed level measuring system 15 is required.
- 7 dead space losses and thus delivery losses are avoided by the over-promotion of the operating fluid 5 in the outlet.
