PURPOSE: To prevent the leakage of the fluid to the outside, and improve the workability of a cylinder by moving a slider by a driving device in the axial direction of a cylinder, and also moving a magnetically connected piston in the cylinder.
CONSTITUTION: A cylinder 30 which is straight and cylindrical and is provided with a suction port 32 and a discharge port 34 at the respective end parts is provided. A piston 40 having a magnet 42 is stored therein in a reciprocatingly linear motion. A valve 48 is provided on one end part on the cylinder discharge port side of the piston 40. A slider 50 having a magnet 52 which is magnetically connected to the magnet 42 of the piston 40 is provided in a reciprocatingly linear motion on the outer circumferential part of a cylinder 30. A pump is provided with a driving device 60 to allow the reciprocatingly linear motion of the slider 50.
