PURPOSE: A compressor using a rotary reciprocating piston for fluid is provided to perform one of rectilinear motion, reciprocation and rotation of a piston by performing the repeated stroke motion with allowing the piston to rotate. CONSTITUTION: A cylinder is mounted in a rotational direction of two and more rotary cylinders centering on a rotatable shaft(2). A piston(20) reciprocates within an allowable angle to suck and compress fluid by a piston shaft(21) in the cylinder. The piston includes a piston body(22) and a piston tail(23), and the piston tail is rotated around a fixed oval shaft(1) having a roller. When the rotary cylinders are rotated, the piston tail is closely adhered to the fixed oval shaft within an allowable angle to reciprocate with difference in height. The piston connected to the piston shaft sucks and compress fluid in the cylinder. The piston is moved to the bottom dead point by a piston shaft spring(25). A fluid compressor compresses the fluid and flows the fluid to the cylinder through a suction port. Thereby, the cylinder has the maximum volume. The piston is prevented from an eccentric abrasion by reciprocating the piston shaft and the piston tail.
