A washing machine includes a water tub arranged in a case and a damper installed between the case and the water tub for damping vibrations of the water tub. The damper includes a plunger having one end supported on the case; a rod having one end supported on the water tub and the other end movably inserted to the plunger; a housing arranged to wrap around some of the plunger and the rod and including a friction member arranged between the housing and the plunger to contact an outer circumferential surface of the plunger; and a switching device configured to be in a first state in which the rod is coupled to the housing and able to move within the plunger along with the housing and a second state in which the rod is decoupled from the housing and able to move solely within the plunger.

A bearing support system includes a bearing disposed within a bearing housing. A bearing damper is disposed around the bearing and includes one or more knitted mesh pads. A compression ring is positioned to be movable relative to the bearing housing and to apply a compression to the bearing damper that results in a change in at least one of a length and a wall thickness of each knitted wire mesh pad and a corresponding change in the stiffness and bearing of the damper. The system supports rotation of a shaft and may include one or more sensors to measure vibrations in the shaft and a controller to control movement of the compression ring in response to the mechanical vibrations.

A laundry treating apparatus includes a main body, a washing tub, and a suspension assembly. The suspension assembly includes a support rod, an elastic member, and a damper. The damper includes a cap, a housing, and a friction member. The friction member is disposed in both the cap and the housing, and is configured to press the support rod through the coupling of the female coupling portion and the male coupling portion.

A damper assembly, in particular for a washing machine, comprises at least one damper which causes a damping effect, in particular an active damper, which can be arranged between two components of the washing machine which are movable relative to one another and can each be connected thereto, a regulation unit which is in signal communication with the damper and is intended to regulate the damping effect of the damper, at least one determination unit, which is in signal communication with the regulation unit, for determining at least one input variable, wherein the regulation unit is designed to transmit a regulation signal to the damper in dependence on the at least one input variable, the damper is designed to variably define its damping effect in dependence on the regulation signal. In addition to the at least one active damper, at least one passive damper can be provided.

Embodiments relate to dynamic stroking seats for vertical take-off and landing (VTOL) aircraft. Seat ballast tanks are attached to aircraft seats. The seats are sprung by a fixed or variable load energy absorption system. The weight of a user is determined and assigned to a corresponding seat of the user. Based on the weight of the user, the fluid level in the ballast tank is monitored and adjusted to achieve a target weight range.

A switchable damper comprises a housing having a longitudinal axis, a plunger displaceable along the longitudinal axis, a piston arranged between the housing and the plunger, a friction lining arranged on the piston and a switching unit, which is switchable between a blocking arrangement, in which the piston is blocked with respect to a displacement along the longitudinal axis, and a free-moving arrangement, in which the piston is released with respect to a displacement along the longitudinal axis.

A tubular vibration-damping device including an inner shaft member and an outer tube member connected by a main rubber elastic body. The outer tube member is configured to be slidably inserted in an attachment tube in an axial direction, and is circumferentially divided so as to be radially deformable or displaceable. A pair of tighteners are disposed on axially opposite sides of the main rubber elastic body. The main rubber elastic body is fastened to an inner circumferential surface of the outer tube member. An adjustment elastic body against which the tighteners are pressed is integrally formed with axially opposite side portions of the main rubber elastic body. Sliding resistance in the axial direction between an outer circumferential surface of the outer tube member and an inner circumferential surface of the attachment tube is settable depending on a pressing force of the tighteners against the adjustment elastic body.

A bearing support system includes a bearing disposed within a bearing housing. A bearing damper is disposed around the bearing and includes one or more knitted mesh pads. A compression ring is positioned to be movable relative to the bearing housing and to apply a compression to the bearing damper that results in a change in at least one of a length and a wall thickness of each knitted wire mesh pad and a corresponding change in the stiffness and bearing of the damper. The system supports rotation of a shaft and may include one or more sensors to measure vibrations in the shaft and a controller to control movement of the compression ring in response to the mechanical vibrations.

A damping system for a truck assembly of a rail vehicle includes a first friction shoe configured to engage a first portion of a side frame of the truck assembly, and a first lever pivotally coupled to the first friction shoe.
