Abstract (en)

[origin: WO2013041777A1] The invention relates to a machine for continuously compressing liquid or gaseous fluids, without lubrication, using a semi-spherical circular wheel which supports vanes and is guided in a semi-spherical circular chamber that is eccentric to the wheel. The compression is performed by means of semi-spheroidal vane technology. The vanes are made from deformable synthetic material. The sealing is provided by a continuous line that runs from the side wall on one side to the side wall on the opposite side, without any form-altering angles. The machine operates without oil owing to its self-lubricating synthetic vanes. Moreover, the machine can also pump, under high pressure, liquid fluids that are not be mixed with the lubricating oil of ordinary pumps.
