- the suction port of the compressor is associated with a supercharger.
- a pre-compressor upstream of the compressor With a pre-compressor upstream of the compressor, 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.
- a supercharger according to the invention can thus be achieved with low construction costs and ensured that the pistons are held in abutment against the slide in the axial piston pump without mechanical retraction device or without changes in the retraction device. This makes it easy. Way possible to adjust the life of the axial piston pump without significant changes to the retraction device to the long life of the piston-less compressor, whereby a low construction cost a long life of the compressor can be achieved using a standardized
- 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 high tightness, thereby providing a standard screw compressor has a long 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.
- Separating device by means of the operating fluid emitted by the compressor into the conveyed medium can be separated from the medium, also from the lubricated with the operating fluid precompressor in the medium emitted operating fluid can be separated. On the suction side of the compressor 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 at least one cylinder space is formed, which is in communication with the displacer, wherein in the cylinder chamber, a piston is longitudinally displaceable, which is supported on a slide, in particular an adjustable swash plate is.
- the displacement cylinders are arranged in a cylinder block and are arranged radially. Due to the radial arrangement of Displacement cylinder in a rotating cylinder block is achieved that acts on the working fluid contained 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.
- a compressor for compressing a gaseous medium in particular of hydrogen
- a pistonless 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 machine can be used as a drive pump for the operating fluid, whereby a low Herstellaufwa ⁇ d with a long Life of the piston-less compressor using standardized components is achievable.
