A fluid compressor according to the present invention comprises an inner conical rotating body (1) being mounted in the interior conical hollow of an outer conical rotating body (2) eccentrically, a spiral type blade (13) having pitches being narrowed gradually and sliding between the inner and the outer conical rotating bodies, and a drive pin (3) being fixed on the inner conical rotating body (1) such that its outer end is fitted in an engaging groove (4) of the outer conical rotating body (2) so as to be movable. The present invention takes advantage of higher compression efficiency and capacity, because of the volume reduction of compression chamber caused both by the spiral type blade having gradually narrowing pitch and by the conical shapes of the inner and outer rotating bodies. |
