摘要： A hinge assembly for a door, the hinge assembly including a hinge pin arranged to be fixed to the door at one end and having a pin connector part at an opposite second end. A rotation damper connected to a damper connector part arranged to cooperate with the pin connector part for transferring torque around an axis of rotation between the damper connector part and the pin connector part throughout an opening angle of the door, such that a rotational movement of the damper connector part about the axis of rotation in at least a first rotational direction is dampened by the rotation damper. The pin connector part and the damper connection part allow an initial closing angle of rotation of the door before the damper acts on the rotation of the hinge pin, the initial closing angle being at least 2°.

摘要： An apparatus combining a door hinge and a door closer is provided. In one embodiment, the hinge provides a variable hydraulic damping speed control with spring action closing, as well as an optional stop action. In one embodiment, the hinge of the present invention includes an adjustable compression spring to operate the opening and closing of the door. After the door has closed to approximately 20 degrees or so, the hydraulic component of the door may then control the speed of the door preferably from approximately 20 degrees until closed. The hydraulic component can also be adjusted to vary the speed and force of the door opening and closing. A pair of magnets may be present in the control cylinder of the hinge to provide more force to complete the closing function. Additionally, a stop function allows for the door to remain open and in place in one embodiment.

摘要： A device has at least two components which are movable relative to one another. The first component is equipped with a rotary receptacle and wherein the second component is rotatably received on the rotary receptacle. A third component is coupled to the second component. Two connection units which are movable relative to one another and a controllable braking device are included, wherein the braking device is designed as a controllable rotary brake in order to provide controlled damping of a movement of a door device between a closed position and an open position. The first connection unit is formed on the first component, and the second connection unit is pivotably coupled to the third component. The pivot axis is oriented transversely with respect to an axis of rotation of the second component.

摘要： A friction hinge with its motion restricted in one pivoting direction includes a support member, a restricting module, and a pivot member. The restricting module is mounted on the support member. The restricting module has an air flow opening. The pivot member is pivotable relative to the support member and the restricting module. A regulating chamber is defined between the pivot member and the restricting module. When the pivot member is pivoted in one direction, a pressure in the regulating chamber is increased and the restricting module is actuated to reduce size of the air flow opening, increasing the resistance to pivoting of the pivot member in this pivoting direction.

摘要： A rotary valve that controls a flow rate at which working oil is supplied to and discharged from a hydraulic cylinder that causes a wing to rotate about a rotary shaft includes a rotor that rotates as the wing rotates about the rotary shaft, and a first control flow passage and a second control flow passage formed in the rotor to control the flow rate at which the working fluid is supplied to and discharged from the hydraulic cylinder, wherein the first control flow passage and the second control flow passage respectively vary a resistance exerted on a flow of the working fluid passing therethrough as the rotor rotates.

摘要： A temperature-independent rotation damper 100 is presented. A housing 108 and a piston 102, between which a viscous liquid is located in annular gaps 118, 120, rotate one around the other. When the temperature falls, the damping by the viscous liquid increases. This effect is countered by reducing the effective area which constitutes the braking action, or by enlarging the volume in the annular gaps 118, 120. As the drive, a material having a positive expansion coefficient is used, which material drives a piston 132. In this way, the damping of the rotation damper 100 is broadly practically independent of the temperature.
