TLDR
In this paper, a rotary damper device comprises a base plate, a rotating cylinder, and a coil spring interconnecting the base plate and the rotary cylinder to generate effective braking force.Abstract:
A rotary damper device comprises a base plate, a rotary cylinder rotatably disposed on the base plate through the medium of a damper, and a coil spring interconnecting the base plate and the rotary cylinder. The base plate and the rotary cylinder are interconnected to the main body of a device and the lid of the device. When the lid is opened or closed, the braking force of the damper and the resilient force of the coil spring cooperate to generate effective braking force and enable the opening-closing device to be opened or closed smoothly under the influence of the effective braking force.read more

Damper for a flapdoor using viscous fluid
TL;DR: In this paper, the authors proposed a damper for a flapdoor that does not show any damping effect when its movable shaft of the damper is rotated with the door in one sense whereas it effectively damps the rotary movement of the flapdoor when the movable shifter is replaced with a movable member depending on the sense of rotation of the shifter.
Patent
One-way rotary damper
TL;DR: In this paper, a one-way rotary damper consisting of a housing, a braking disk and a shaft unitary with the braking disk, projecting toward the outside of the housing, viscous oil filling the housing cavity for applying shearing resistance against rotation of the rotor, and a driven gear rotatably mounted upon the end of a rotor shaft projecting outside the housing so as to be free to rotate with respect to the rotor.
Patent
Actuator for movably supported object
TL;DR: An actuator for a movably supported object, comprising a rack, a rotatable pinion engaging the rack and a biasing member disposed around the axis of the pinion and connected to the pinions, and a damper was presented in this article.
Patent
Temperature compensated rotary damper
TL;DR: In this paper, a temperature compensated fluid filled damper is provided which in a preferred embodiment is a rotary damper which includes a housing for receiving a rotor having a surface for engaging a viscous fluid sealed within the housing.
Patent
Furniture hinge with damping device
TL;DR: In this paper, a furniture hinge with damping and/or braking device is presented, which is capable of guaranteeing an improved efficiency during closing or opening operation of the doors, or other furniture parts, thanks to an improvement of the kinematic motion for transmitting motion from one of the rockers to the damping elements.

Rotor movement damping device
TL;DR: A rotary damping device has a shaft provided at one end with a rotor and the shaft also has a damping portion extending radially as mentioned in this paper, which is rotatably housed and accommodation spaces in the device are filled with oil.
Patent
Damping device for hinges and the like
TL;DR: In this article, a spring is used to biasing a door or other similar structure into a closed position and a fluid medium for damping movement of the door, which is achieved by compelling the fluid to pass from one chamber to another within a housing of the device by changing the volumes of the chambers.
Patent
Adjustable door hinge containing coil spring
TL;DR: In this paper, a tubular pivot pin inside the barrel of a pair of hinge leaves contains a coil spring, one of which is provided with an axial passage through it having an adjustment member with an outer portion rotatably mounted in the passage and an inner portion projecting from the inner end of the plug.
