Patent ID: 7789208

Claim:
A shock absorber, comprising: a cylinder defining a compression chamber and a rebound chamber; a piston provided between the compression and rebound chambers, the piston having a rebound channel and a valve mechanism to generate a damping force by controlling opening and closing of the rebound channel and an opening degree of the rebound channel, wherein the valve mechanism comprises: a first valve disk having a hole and a slit communicating with the rebound channel respectively provided in inner and outer sides of the first valve disk, the first valve disk generating a first damping force by directing fluid through the slit; an auxiliary disk having a hole communicating with the hole of the first valve disk, the auxiliary disk being disposed to be in contact with a lower side of the first valve disk; and a second valve disk disposed to be in contact with a lower side of the auxiliary disk, the second valve disk being configured to be subjected to bending deformation by the fluid flowing through the holes of the first valve disk and the auxiliary disk to generate a second damping force.
