Abstract:
A damper roller system is provided. The system includes an external rotating element connected to a bearing housing. The bearing housing is filled with a viscous fluid and includes at least one bearing element immersed in the viscous fluid. The bearing housing is connected to at least one sealing element sealing the viscous fluid inside the bearing housing. The bearing element is connected to a non-rotating shaft having opposite first and second ends. The shaft is held in place at the first end by the bearing element and is rigidly connectable at the second end to an object. The first end is nail-shaped and immersed in the viscous fluid. A rotation of the external rotating element drives a common rotation of the bearing housing and of the bearing element, and shears the viscous fluid, causing a damping motion proportional to a rotational speed of the external rotating element.

Abstract:
A rotary damper comprises a casing fixable to a structure and which comprises a wall which surrounds a chamber filled with a viscous fluid and has an inner surface facing the chamber. A cover is mounted and welded on a shoulder surface of the wall of the casing in such a way as to close the chamber in a sealed manner. A rotor which is mounted rotatably on the casing and comprises a disc portion, adapted to rotate within the chamber, and has a shaft portion extending axially from the disc portion and emerging through the cover so as to be operationally associable with a movable member. The cover has peripherally a collar-like protuberance, extending along the entire perimeter of the cover and coupled to the inner surface of the wall of the casing in such a way as to oppose the infiltration of the viscous fluid between the collar-like protuberance and the inner surface of the wall.
Abstract:
The present invention relates to an actuator (1), comprising an output member (6); a resilient element (8) connected to said output member (6) so as to urge it in a first direction; and an hydraulic rotation damper (5) with a closed cylinder cavity, a rotational damper shaft which extends into the cylinder cavity, and a piston dividing the cylinder cavity into a first side and a second side. Within the rotation damper (5), the rotational movement of the damper shaft is converted into a translational movement of the piston along a longitudinal axis of the shaft. A restricted fluid passage communicates said first and second sides. The damper shaft is connected over a gearing (10, 15, 17) to the output member (6) and resilient element (8) of the actuator for damping movement of said output member (6) in said first direction.The present invention relates to both rotational and linear actuators as well as to a closing mechanisms for hinged members, such as doors, gates, or windows, comprising such actuators.
Abstract:
A damping device comprises an axle, a housing, a unidirectional member, and a damping oil. The unidirectional member in cross section is formed like a T-shape, and a top portion thereof is formed as an arc to cooperate with the housing's inner wall. Where the unidirectional member contains a U-shaped slot defines oil holes interlaced with the gap of the first slot wall. The lifting of the cover is free from damping and the closing thereof performs a well damping capability. Even only a narrow angle is lifted, a delicate damping is still achieved. The undersized unidirectional member concurrently guarantees the structural strength. The diminished cross-section of the unidirectional member contributes to a smaller U-shaped slot. Therefore, while satisfying the turning angle, the thicknesses of the U-shaped slot's wall and the obstructing wall are assured to greatly prolong the using life of the present invention.

A household appliance that includes a housing having an opening; a door rotatable about a first rotation axis to selectively open or close the opening; and a braking system to damp a rotational movement of the door when the door is opened or closed. The braking system includes a damper and a transmission unit that is coupled between the door and the damper to be driven by the door and for transmitting a movement of the door to the damper.
Abstract:
A door opening and closing device has a rotational mechanism configured to switch a door between a closed position and an open position relative to a base member. The door opening and closing device includes a latch mechanism for latching the door in the closed position on the base member. The latch mechanism includes a latch device attached to the base member, a case disposed above the latch device, a slider slidably situated in the case above the latch device, and a latching member pivotally supported by the case and including a base end slidably connected with the slider and a tip configured to engage a portion of the door. When the door is moved to the closed position, the slider is moved by the door and is engaged with the latch device while the latching member is pivoted to engage the door.
Abstract:
A driving device for an adjusting system of a motor vehicle includes a transmission with a drive element rotatably mounted about an axis of rotation for introducing a torque, a driven element rotatably mounted about the axis of rotation for delivering a torque, and a wrap spring brake device for transmitting a drive-side torque introduced by the drive element to the driven element and for blocking a driven-side torque applied on the driven element. It is provided that the drive element and the driven element each are mounted on a stationary portion of the transmission. In this way a driving device is created, whose drive element and driven element can have low bearing tolerances and which in addition is optimized in terms of friction to provide a smooth operation.

A viscous rotary damping device for a vehicle end gate assembly is provided. The damping device includes a housing member configured to operatively attach to the vehicle body or the end gate assembly. The housing member defines a fluid chamber having viscous fluid therein. The damping device also includes an impeller member having a mast with a first end configured to operatively attach to the other of the vehicle body and the end gate assembly, and a second end having one or more blades projecting outward therefrom. The second end of the mast is rotatably received in the fluid chamber such that the impeller member dissipates kinetic energy generated by the end gate assembly when transitioning between a first, closed position and a second, open position. A cover plate member is preferably coupled to the housing member, and configured to fluidly seal the fluid chamber.
