摘要： A fluid damper is provided including a cylinder filled with a damping fluid, a piston base body shiftably guided in the cylinder along a stroke axis, and a valve disk spaced apart from a shell wall of the cylinder. The piston base body divides an inner space of the cylinder into a front space and a rear space along the stroke axis. In the piston base body, there is at least one channel connecting the front space to the rear space in a fluid-conducting manner. The valve disk is shiftably guided along the stroke axis between an opening position unblocking the at least one channel and a closing position closing the at least one channel. The valve disk has a central area extending radially outward from the stroke axis, the central area being free of apertures.

摘要： Disclosed herein is an over-slam bumper for a vehicle. The over-slam bumper includes: a bumper unit (100) of which an end portion protrudes toward a door to absorb shock generated between a vehicle body and the door; and a mounting unit (200) coupled with the bumper unit (100) to fix the bumper unit to the vehicle body, wherein the bumper unit (100) includes: an elastic part for absorbing shock generated when getting in contact with the door; and a coupling part (116) connected to the elastic part and coupled with the mounting unit (200). The elastic part includes a buckling part (111) for absorbing shock by buckling; a compression part (130) for absorbing shock by compression; and an elastic air compression part for absorbing shock by sealing the inside air to compress inside air.

摘要： The object of the invention is the hinge for controlled door closing and opening with damper which solves the technical problem of smooth and controlled closing and opening of the door before the end positions of the hinge, i.e. the open or closed position of the door. The damper fit surface (25) and the damper head fit surface (26) are always in contact with two of the limiting surfaces, i.e. two of the following: the damper stop on the housing for closing (21), the damper stop on the housing for opening (22), the damper stop on the guide for opening (23) and the damper stop on the guide for closing (24), whereby the damper (5) in the initial position constantly applies force in the direction of extension, meaning that the damper (5) constantly applies force to increase the distance between the damper fit surface (25) and the damper head fit surface (26), whereas the hinge guide (3) is dimensioned in such a way that the distance between the damper stop on the guide for opening (23) and the damper stop on the guide for closing (24) is smaller than the maximum distance between the damper fit surface (25) and the damper head fit surface (26).

摘要： A damper has a shell with a cavity. A rotating shaft is rotatably inserted into the cavity of the shell, the portion of the rotating shaft located in the cavity is provided with external thread; a guiding sleeve with internal thread can move along axially reciprocatingly to attach to the shell cavity, and the internal thread and the male thread of the rotating shaft are screwed together; A guiding structure is provided in the shell cavity. The guiding sleeve is engaged or disengaged with the guiding structure by axial movement, and when the two are disengaged, the guiding sleeve can rotate with the rotating shaft. The guiding sleeve is provided with a one-way valve passage. The one-way valve passage opens when the guiding sleeve is axially disengaged with the guiding structure. When the guiding sleeve moves axially in the reverse direction, the one-way valve passage is closed.
