The present invention relates to a fluid-circulating device using a cam track and centrifugal force, wherein the fluid-circulating device comprises, to drive a piston by the centrifugal force of radially arranged weights so as to circulate a fluid, a rotating body (10) which is connected to a motor (11) and which has a central axis with an inlet shaft (12), and an outlet shaft (13) arranged at the respective ends of the central axis, wherein the inlet shaft (12) and the outlet shaft (13) have respective flow channels (12a, 13a), and wherein the rotating body (10) has an outer surface on which radial flanges (14) are arranged; a plurality of cylinders (20) fixed at the rotating body (10) to enable a piston (21) to reciprocate; a plurality of weights (30) connected to the piston (21) through a link; a cylindrical cam track (40) which is arranged eccentrically from the central axis of the rotating body (10), and the inner surface of which contacts each weight (30); a first radial flow channel (121) formed in the rotating body (10) to enable the flow channel (12a) formed in the inlet shaft (12) to communicate with each cylinder (20); a second radial flow channel (131) formed in the rotating body (10) to enable the flow channel (13a) formed in the outlet shaft (13) to communicate with each cylinder (20); and a suction valve (122) and a discharge valve (132) installed in the first radial flow channel (121) and second radial flow channel (131), respectively. |
