It is possible to prevent occurrence of a resonance phenomenon of a hydraulic unit and to improve attachability/detachability of the hydraulic unit to/from a bracket. A support section (42, 43) includes: a fixture member (80) that is fixed to a housing (30) for a hydraulic unit (10); and a vibration absorbing member (75) that is interposed between the housing (30) and a bracket (41) and has a through-hole (75a) through which the fixture member (80) passes. The vibration absorbing member (75) includes two vibration absorbing members (75B, 75C, 75D) having different rebound resilience from each other. In a state where the vibration absorbing member (75) is partially accommodated in a recessed section (47) of the bracket (41), the vibration absorbing member (75) is held between the housing (30) and the bracket (41).

Provided is an anti-vibration device which is provided between a vibration-side bracket attached to a vibration member and a non-vibration-side bracket attached to a non-vibration member, the anti-vibration device including: a first attachment member attached to the vibration-side bracket; a second attachment member attached to the non-vibration-side bracket; and an insulator provided between the first attachment member and the second attachment member, wherein the first attachment member includes a stopper portion which faces an engagement portion formed on the non-vibration-side bracket, and the insulator includes a cover portion which covers at least a surface of the stopper portion facing the engagement portion.

A jounce bumper of an automotive vehicle suspension system contains a longitudinal axis. The jounce bumper is configured to resiliently deform between an uncompressed state and a compressed state, where in the compressed state the jounce bumper has a smaller length in the direction of the longitudinal axis than in the uncompressed state. The jounce bumper also contains a base body that acts as a primary spring element, where the base body is partially or completely made of a volume-compressible first material. In particular, the base body further contains at least one secondary spring element integrated within the base body. The secondary spring element is resiliently deformable between a first length in the uncompressed state and a second length in the compressed state, where the second length is smaller than the first length. The secondary spring element is partially or completely made of a compact second material.

A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

A flex cell for absorbing energy from an applied force includes a panel attached to a flex cage. The flex cage is made from a resilient material that allows deformation of the flex cage when a force is applied to the flex cell. The flex cell is attachable to a support surface. In some instances, the flex cell is detached from the support surface when sufficient force is applied to the flex cell.

A locking isolator includes one or more joints. The one or more joints are configured to transition between a clearance fit state and an interference fit state in response to a change in temperature. The locking isolator includes a dampener. The dampener is configured to attenuate transmission of vibration through the one or more joints when the one or more joints are in the clearance fit state.

A vibration dampening device, a mounting assembly including a vibration dampening device, and a method of dampening vibration in a vibration-sensitive component using the same. The vibration dampening device includes a first member that rests upon or is operatively engaged with a support surface; a second member that is operatively engaged with the vibration-sensitive component; and at least one isolator assembly interposed between the first member and the second member, wherein the first member and the second member are decoupled from one another by the at least one isolator assembly. The at least one isolator assembly includes a first isolator that is at least partially embedded in the first member and a second isolator that is at least partially embedded in the second member, and an isolator insert that extends between the first isolator and second isolator. The isolator insert creates a gap between the first and second members.
