  • the invention relates to a device comprising a compressor with at least one displacement cylinder, in which an operating fluid, in particular an ionic liquid, is arranged and which can be brought into communication with a suction port and a delivery port for medium, wherein the operating fluid is in operative connection with a drive pump.
  • an operating fluid in particular an ionic liquid
  • Such compressors are used for compressing gaseous media.
  • the medium is in this case displaced by means of the operating fluid in the displacer cylinder, whereby such compressors are referred to as piston-free compressor.
  • the operating liquid an ionic liquid can be used.
  • 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.
  • the operating fluid is in this case conveyed by means of a designed as axial piston pump drive pump in the displacement and sucked from the displacement cylinders to promote the medium of the suction port in the delivery port and put under pressure.
  • a designed as axial piston pump drive pump in the displacement and sucked from the displacement cylinders to promote the medium of the suction port in the delivery port and put under pressure.
  • a generic pistonless compressor has a long service life due to the lack of mechanical seals and missing pistons in the displacement cylinders.
  • the adaptation of an axial piston pump with a mechanical retraction device to the high life of the pistonless compressor also requires a high construction cost.
  • the present invention has for its object to provide a device of the type mentioned is available, which has a long service life with low construction costs.
  • the drive pump is designed as an axial piston pump, wherein the operating fluid is conveyed by means of the axial piston pump in the displacer and sucked from the displacer cylinder to promote the medium of the suction port in the delivery port, wherein the axial piston at least one cylinder chamber in which a piston is arranged longitudinally displaceable, which is supported on a slide, in particular an adjustable swash plate, and the suction port of the compressor is associated with a supercharger, which generates a pre-pressure of the medium to the piston of the axial piston pump in contact with the slide to keep.
  • a minimal pre-pressure of the medium to be delivered can be generated in a simple manner at the suction connection of the compressor.
  • This pre-compressor generated by the supercharger is on the operating fluid, which is in direct contact with the medium to be conveyed, also on the axial piston pump and acts on the piston of the axial piston pump in the suction cycle in the direction of the slide.
  • the supercharger is designed according to a preferred embodiment of the invention as a screw compressor. Due to the long service life of a pistonless compressor, it is necessary to select a supercharger with a correspondingly long service life in order to prevent the supercharger from being the weakest link in the service life chain.
  • a screw compressor does not require operating seals that have a high density, whereby a standardized screw compressor has a long service life.
  • a screw compressor has low pulsations, whereby low noise emissions and low load on the compressor on the suction side can be achieved.
  • the supercharger can be lubricated by means of the operating fluid.
  • the operating fluid By lubricating the supercharger by the operating fluid is avoided that contamination of the medium to be delivered occurs through the use of the supercharger. Due to the lubrication with the operating fluid, the screw compressor emits only the operating fluid already present in the process, whereby a deterioration in the function of the compressor does not occur.
  • a separation device for separating operating fluid located in the conveyed medium is associated with the delivery connection of the compressor.
  • a separating device by means of which the operating fluid emitted by the compressor into the conveyed medium can be separated from the medium, the operating fluid emitted by the precompressor lubricated with the operating fluid can likewise be separated off into the medium.
  • no further separation device is thus required in order to deposit through the lubricated by the operating fluid screw compressor possibly in the medium to be pumped operating fluid.
  • the axial piston pump to a cylinder drum, in which the at least one cylinder space is formed, which is in communication with the displacer cylinder.
  • a connection of the positive displacement cylinder with the cylinder space and thus the piston can be achieved in a simple manner to achieve a safe abutment of the piston on the slideway formed by the swash plate in the suction cycle of the drive pump with the pre-compressor generated by the supercharger.
  • the displacement cylinders are arranged in a cylinder block and are arranged radially. Due to the radial arrangement of the displacer cylinder in a rotating cylinder block is achieved that acts on the working fluid located in the displacement of a centrifugal force, which allows a high speed of the compressor. This can be achieved with a small space requirement of the compressor, a high flow rate. In addition, only a small amount of operating fluid is required, causing the compressor low production costs and operating costs.
  • the cylinder block and the cylinder drum are rotationally synchronously coupled or integrally formed according to a preferred structural embodiment of the invention.
  • a pressure of 5-15 bar in particular a pressure of 8-10 bar, can be generated when using a standardized axial piston pump as a drive pump for the operating fluid a safe concern of the piston on the slide formed by the swash plate in Operation of the compressor can be ensured.
  • the compressor may be designed to convey liquids.
  • the compressor for compressing a gaseous medium in particular of hydrogen
  • a piston-less compressor according to the invention in which by means of a standardized supercharger, which is lubricated by the operating fluid, a pre-pressure of the gaseous medium can be generated on the suction side, a standardized axial piston pump can be used as a drive pump for the operating fluid, whereby a low manufacturing cost with a long life of the pistonless compressor using standardized components can be achieved.

  • the displacer cylinder 6 are in the radially inner region in each case with a connecting channel 8 in communication, which is in operative connection with a disc-shaped control mirror 9, wherein by means of the control mirror 9, the compound of the displacer 6 during rotation of the cylinder block 5 with a suction port 10 and a delivery port 11th is controllable.
  • the cylinder block 5 is in this case supported in the axial direction on the control mirror 9, which is arranged on a housing cover 12 attached to the housing 2.
  • Each displacer cylinder 6 is connected by means of a connecting channel 13 with a cylinder chamber 16 of a hydraulic pump designed as an axial piston pump 17 in swash plate design.
  • the drive pump embodied as an axial piston pump 17 in this case has a cylinder drum 18 which is arranged coaxially with the cylinder block 5 and is non-rotatably connected with the cylinder block 5 or the drive shaft 3. It is also possible to form the cylinder drum 18 and the cylinder block 5 as a common and thus one-piece cylinder drum.
