Title:
OPERATING DEVICE UTILIZING MAGNETIC FLUID
Document Type and Number:
Japanese Patent JPS60197155
Kind Code:
A
Abstract:
PURPOSE:To accurately regulate the displacement of a movable element by movable providing a pistonlike movable unit in a stationary unit, and moving the movable unit by magnetic fluid attracted by the excitation of a solenoid. CONSTITUTION:An operating device 1 is composed by inserting a magnetic core 3 into one end hole of a cylinderlike stationary unit 2 opened at both ends, and winding a solenoid 4 on the core 3 extending outside from one end opening of the unit 2. One end of a movable table 6 is inserted into the other end hole of the unit 2, and a piston-like movable unit 7 is hermetically movably mounted in the unit 2 via an O-ring 8 at one end. Thus, when the solenoid 4 is energized from a power source, the core 3 is magnetized to attract and flow magnetic fluid 11 in a vessel 12 into a magnetic fluid chamber 13. The unit 7 is affected by the pressing force by the flow of the fluid 11 to move forward into the unit 2, thereby moving the table 6.
