Class Information
Number: 188/378
Name: Brakes > Inertia of damping mass dissipates motion (e.g., vibration damper)
Description: Device including first and second relatively movable members, wherein the second member includes a relatively heavy damping mass and the motion is restrained by an opposing force resulting from the inertia of the damping mass.
