ABSTRACT:
A fluid compressor comprises a hollow cylinder closed at the axially opposite ends, a cylindrical turning body disposed within the cylinder and provided with a helical groove formed on the outer peripheral surface of the cylinder, the axis of the turning body being eccentrically displaced from the axis of the cylinder by a given distance, and a blade held and vertically movable in the groove in the direction of the depth of the groove as a compressing element, the compressor drawing operating fluid into the cylinder through a suction port disposed at an end of the cylinder, transferring the drawn-in fluid toward a discharge port disposed at the other end of the cylinder and eventually discharging the fluid through the discharge port by the rotary movement of the turning body as the object of compression, wherein, when the given formula is expressed in terms of the circumferential coordinate and the axial coordinate of the turning body, the values obtained as a result of "differentiation of second order" of the axial coordinate by the peripheral coordinate of the given formula show an approximately continuous distribution.
