F16F15/283 - CPC Classification

Classification description:

Suppression of vibrations in systems ; Means or arrangements for avoiding or reducing out-of-balance forces, e.g. due to motion; Counterweights, i.e. additional weights counterbalancing inertia forces induced by the reciprocating movement of masses in the system, e.g. of pistons attached to an engine crankshaft ; Attaching or mounting same for engine crankshafts
