Abstract: The present invention relates to a fluid compressor having an aerostatic bearing, to a control system of a fluid compressor having an aerostatic bearing as well as to a method of controlling a compressor, wherein the aerostatic bearing is fed by a compressed fluid accumulator (5) which is charged during the operation of the compressor (100) and discharged at the respective start to prevent damage to the bearings.

Abstract: A compact compressor comprising a first tubular housing portion; a second tubular housing portion having a first end region open to the first tubular housing portion and a second end region defining a compression chamber and housing a piston; an electric motor carried by the first tubular housing portion; a driving means connecting the piston to the electric motor; a valve plate seated against the second end region of the second tubular housing portion; and an end cover fixed to the second tubular housing portion and acting against the valve plate and providing, internally and through the valve plate, fluid communications between the compression chamber and the suction line and discharge line of a refrigeration circuit to which the compressor is coupled.
