A support for household appliance includes a hydraulic plate which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate and the sheath can be rapidly, reliably and fixedly connected, the requirements on the strength of connection between the hydraulic plate and the sheath are lowered, and the essential space and height required by the connection are further lowered.

A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

A vibration isolator includes a first conical disc spring member having a first end and a second end. A first-end spacer in contact with the first spring member first end, and a second-end spacer in contact with the first spring member second end. A second conical disc spring member has a first end and a second end. The second spring member first end is in contact with the first-end spacer. Another second-end spacer is in contact with the second spring member second end. A flexible housing of the isolator defines an interior. The housing is in contact with and extends between the second-end spacer and the other second-end spacer so that the first-end spacer and the first and second spring members are received in the housing interior. The housing includes a plurality of spaced-apart through holes formed therealong between the second-end spacer and the other second-end spacer.

A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. The damper unit includes a slider configured, upon horn activation, to slide on a guide shaft. A damper element made from an elastomeric material is arranged on a first part of the slider. A molded horn spring element is molded directly on a second part of the slider and is configured to exert a spring force on the slider. The damper unit provides a unitary structure providing both a vibration damping function and a horn spring function in one single assembly unit, reducing the number of components to assemble. A vibration-reducing damper assembly including one or more such damper units is also disclosed, as well as a method of making such a damper unit.

A weight applicator including a weight applicator head and at least one actuator is disclosed. The weight applicator head is adapted to carry a wheel balance weight and has a weight application surface with a weight retaining region and a leading rotation region. The at least one actuator is coupled to the weight applicator head for manipulating the weight applicator head in at least one direction. The at least one direction has a radial component. The leading rotation region is oriented to extend radially further than the weight retaining region.

An assembly for damping the movement of a vibrating body includes an energy dissipating material, a vessel, and a seal. The energy dissipating material may include one or more types of loose particles. The loose particles may include similar and/or dissimilar materials or a mixture thereof. The loose particles may at least partially fill the vessel. The vessel may be configured to conform to requirements of an environment of the vibrating body and to retain and/or store the loose particles. The seal may include a molded material, a plate, and/or a flange. In an embodiment, the plate may be at least partially encompassed within the seal, and the seal, plate, and/or flange may be configured to engage the vessel and/or to retain the loose particles within the vessel.

A spring assembly comprises a spring with a coating, a spring retainer made of plastic material, an adhesive layer by which the spring and the spring retainer are bounded adhesively to one another, wherein the hardness of the adhesive layer is lower than the hardness of the coating. Further, a process of producing such a spring assembly is provided.

A microelectromechanical membrane transducer includes: a supporting structure; a cavity formed in the supporting structure; a membrane coupled to the supporting structure so as to cover the cavity on one side; a cantilever damper, which is fixed to the supporting structure around the perimeter of the membrane and extends towards the inside of the membrane at a distance from the membrane; and a damper piezoelectric actuator set on the cantilever damper and configured so as to bend the cantilever damper towards the membrane in response to an electrical actuation signal.

A vibration and sound deadening treatment applied to the exterior of downspouts or other gutter pieces which quiets any sound generated when water or other weather contacts the downspout. When placed on the exterior of the downspout, especially near turns in the spout, sound generated by rain and water moving through the downspout is dampened by reducing or removing completely the vibrations generated by the rain and water. This prevents the need to place anything inside of the downspout that may wind up clogging the spout and drain.

A multilayer damping material for damping a vibrating surface comprising: at least one constraining layer; at least one dissipating layer; and at least one kinetic spacer layer comprising multiple spacer elements. The kinetic spacer layer is arranged between the constraining layer and the vibrating surface, when used for damping the vibrating surface. Each spacer element has opposite ends. At least one end of each of the multiple spacer elements is embedded in, bonded to, in contact with, or in close proximity to the dissipating layer, such that energy is dissipated within the multilayer damping material, through movement of the at least one end of each of the multiple spacer elements.
