Title:
DAMPER WITH VARIABLE DAMPING FORCE
Document Type and Number:
Japanese Patent JPS63231031
Kind Code:
A
Abstract:

PURPOSE: To gain necessary damping force freely by reserving magnetic fluid in a cylinder and fixing one end of a rod to an annular solenoid with holes provided for making said fluid pass through for changing voltage or current applied to the solenoid.

CONSTITUTION: Magnetic fluid 12 is reserved in a cylinder 11 and an annular solenoid 13, to which one end of a rod 14 is fixed is inserted therein. Plural numbers of holes 13c through which the magnetic fluid 12 passes are made in this annular solenoid 13 and voltage or current is made to change. Therefore, electric power consumption can be reduced by making leakage flux minimum and necessary damping force can be set freely.
