A vibration damping assembly for use with an automotive vehicle is provided. The assembly includes a bracket having a C-shaped receptacle, a component such as an air cleaner housing having an integrally-formed, grommet-holding cylindrical post extending therefrom attached to the bracket, and a spool-shaped isolator mounting grommet attached to the post. The post includes a proximal end integrally attached to the component and a distal end. The distal end includes at least one integrally-formed retention barb and preferably includes two spaced-apart and integrally-formed barbs. The post includes an attachment end attached to the component and an unattached end opposite the attachment end. The barbs are formed on the unattached end. Each barb includes an upper edge extending beyond the unattached end of the post. Each barb includes a ramped, grommet-passing surface. The spool-shaped isolator mounting grommet may be formed from materials such as TPO, TPE, AEM, ECO, and EPDM.

A module for a braking system includes a movable housing configured to transfer a braking force from an input shaft to an output shaft, a first movable member slidably received within the housing and connected to the output shaft, a second movable member slidably received within the housing, a first resilient member biased between the first movable member and the second movable member, such that a force applied to the second movable member is applied to the first movable member via the first resilient member, and a second resilient member biased between the second movable member and the housing, such that a force applied to the housing is applied to the second movable member via the second resilient member. The first resilient member yields or compresses upon application of a first braking force to the input shaft, and the second resilient member yields or compresses after the first resilient member.

A damper device provided between a fixed body having an opening portion and an openable and closable body mounted on the opening portion and configured to apply a braking force to the openable and closable body. An elastic resin member is mounted on a projecting portion provided on the openable and closable body. A receiving recess portion is provided on the fixed body to receive the elastic resin member. The elastic resin member has a base portion; a pair of arm portions; a bridge portion; and a stopper, which are formed integrally. The receiving recess portion has: an introducing portion configured to abut with the arm portions to bend them diametrically towards each other; and a restricting portion configured to abut with the stopper to restrict the openable and closable body from opening, when the openable and closable body opens to cause the elastic resin member to move.

The present invention relates to a displacement-controlled earthquake-resistant transformer employing a friction damper, including: a device body; an upper frame disposed in an upper portion of the device body to fix the device body; a lower frame disposed in a lower portion of the device body to fix the device body to a base while supporting the device body; and a friction damper unit disposed between the device body and the base to interwork with the device body and the base, and configured to buffer a vibration transmitted to the device body through the base fixed to a ground surface. According to the present invention, seismic energy is absorbed by using a frictional force of a damper in the event of an earthquake, so that damage that may be caused to the transformer by an earthquake shock is prevented.

An actuator is provided for an aircraft engine and includes a tubular base layer and a visco-elastic layer adhesively disposed on the tubular base layer.

A buffer stopper capable of increasing an absorbable energy amount without causing changes in characteristics due to wear of a buffer body. In order to achieve the object, the buffer body containing a rubber elastic body disposed between an end surface formed in a housing and an end surface formed in a shaft which is relatively movable in the axial direction with respect to the housing and a wear resistant sheet which is provided so as to surround the outer peripheral surface of the buffer body and which can contact an inner peripheral surface of the housing by expansion and deformation in the radial direction of the buffer body are provided.

The receiving recess portion has: an introducing portion configured to abut with the arm portions to bend them diametrically towards each other; and a restricting portion configured to abut with the stopper to restrict the openable and closable body from opening, when the openable and closable body opens to cause the elastic resin member to move.

A module for a braking system includes a movable housing configured to transfer a braking force from an input shaft to an output shaft, a first movable member slidably received within the housing and connected to the output shaft, a second movable member slidably received within the housing, a first resilient member biased between the first movable member and the second movable member, such that a force applied to the second movable member is applied to the first movable member via the first resilient member, and a second resilient member biased between the second movable member and the housing, such that a force applied to the housing is applied to the second movable member via the second resilient member. The first resilient member yields or compresses upon application of a first braking force to the input shaft, and the second resilient member yields or compresses after the first resilient member.

A device configured for insertion between two parts of a rotary wing aircraft that are likely to undergo a repeated relative movement. The device includes at least two frame elements intended to be mounted on at least one of the two parts of the aircraft, and at least one layer of elastomer positioned between the two frame elements, the at least one layer defined by a first surface belonging to the inner volume of the device, a second surface also belonging to the inner volume of the device, and an outer surface not belonging to the inner volume of the device. The inner volume of the device includes at least two independent pouches each positioned at a predetermined distance from the outer surface, each pouch being filled with a product capable of flowing outside its pouch when a crack has spread from said outer surface toward the pouch in question.

A variable damping shock absorber includes a housing and a piston rod capable of sliding along an inner wall of the housing. A first damping unit is fixedly arranged on the piston rod, which moves with the piston rod and generates frictional force with the inner wall of the housing. An accommodating space is formed between a part of the piston rod and the inner wall of the housing. A second damping unit matched with the inner wall of the housing is arranged in the accommodating space. The second damping unit vertically moves along the inner wall of the housing, and generates frictional force with the inner wall of the housing.
