Abstract: Disclosed is a pneumatically operated fluid-filled active vibration-damping device including: a primary fluid chamber partially defined by an elastic body and filled with a non-compressible fluid; a movable member being elastically displaceable and partially defining the primary fluid chamber its one side; a working air chamber disposed on the other side of the movable member; and an air reservoir directly extending from the working air chamber and fluid-tightly closed at its protruding end portion. A fluid pressure variation in the primary fluid chamber is induced by an elastic deformation of the elastic body while being actively controlled by transmitting an air pressure variation applied to the working air chamber from an external area to the primary fluid chamber via the movable member. A vibration-damping apparatus using the vibration-damping device is also disclosed.

Abstract: A vibration-damping device includes a housing member and a pillar-shaped mass member housed within an accommodation space of the housing member with a slight spacing therebetween so that the mass member is freely displaceable within the accommodation space to come into impact on the housing member. A rubber buffer and an abutting rubber member integrally formed with each other and fixed to at least one of axial end portions of the mass member such that the rubber buffer covers an outer circumferential surface of the end portion of the mass member, and the abutting rubber member disposed over an end face of the axial end portion of the mass member. A void is formed between the abutting rubber member and the end portion of the mass member so that the abutting rubber member undergoes shear deformation upon an impact of the mass member on the housing member at the abutting rubber member.

Abstract: A vibration-damping device comprising: at least one rigid housing member fixedly disposed in a vibrative member; and a plurality of independent mass members disposed non-adhesively and independently in the at least one housing member such that each of the plurality of independent mass members is opposed to the at least one housing member with a given spacing therebetween in a vibration input direction, and is displaceable relative to the at least one housing member. The each independent mass member is independently displaced relative to the at least one housing member so that the independent mass member and the housing member are brought into elastic impact against each other at their respective abutting surfaces which are opposed to each other in the vibration input direction.

Abstract: Vibration damping device for vehicles includes: a rigid housing member having an accommodation space and fixed to a vibrative member; and an independent mass member having a rigid mass body and an elastic body layer bonded on the outer surface of the rigid mass body. The independent mass member is non-adhesively disposed in the accommodation space such that an outer surface of the independent mass member is opposed to the inner surface of the housing member with a predetermined gap distance therebetween, to thereby permit displacement of the independent mass member relative to the housing member. The independent mass member and the housing member is brought into elastic impact against each other, upon application of a vibrational load, at respective abutting surfaces thereof which are opposed to each other in a vibrational input direction.
