IPC: F16F9/19
Filed: 2003-10-24
Abstract: <P>PROBLEM TO BE SOLVED: To restrain generation of heat and heighten the variable responsiveness of damping force.  <P>SOLUTION: A piston 4 with a piston rod 3, the tip side of which is slidably passed through one end of a casing 1, is stored in the casing 1, thereby forming two fluid chambers 5a, 5b partitioned by the piston 4. A passage 7 is formed as a clearance gap between the outer peripheral surface of the piston 4 and the inner wall surface of the casing 1, and the fluid chambers 5a, 5b and the passage 7 are filled with a magnetic fluid 6. A magnetic force generating mechanism 21 formed by integrally fitting a piezoelectric element 22 to a supermagnetostrictive element 23 is provided in the interior of the piston 4, and an external power supply 10 is connected to the piezoelectric element 22 through an electric wire 11. In the case of changing the damping force, an electric current is applied to the piezoelectric element 22 to apply distortion of the supermagnetostrictive element 23 with deformation of the piezoelectric element 22, thereby generating magnetic field. The magnetic field is applied to the magnetic fluid 6 to heighten the viscosity of the magnetic fluid 6, whereby the damping force is increased by heightening the resistance when the magnetic fluid 6 passes through the passage 7.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
