Title:
ACTUATOR USING MAGNETIC FLUID
Document Type and Number:
Japanese Patent JPS60200758
Kind Code:
A
Abstract:
PURPOSE:To obtain a ready, accurate and compact actuator by filling magnetic fluid through two cylinders which respectively contain pistons, and moving the pistons by electromagnetic forces. CONSTITUTION:An acutuator has cylinders 1, 2, pistons 3, 4 slidably contained respectively in the cylinders, a piston rod 5, magnetic fluid 6 filled between the pistons 3 and 4, and control coils 7, 8 for controlling the flow of the fluid 6. A current is flowed from a power source 9 by a current controller 10 in the coils 7, 8. Thus, the fluid 6 is attracted by one energized coils 7, 8 to move in the cylinders 1, 2, thereby moving the pistons 3, 4.
