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.

A vehicle includes an exhaust, a frame hanger connected to a body of the vehicle, and an isolator connecting the exhaust to a body of the vehicle via the frame hanger such that the exhaust rotates about the frame hanger. The vehicle further includes a first frame bracket having a fixing portion fixed to the body of the vehicle and an engaging portion located near the isolator at a first distance. The first distance defines a first maximum allowable displacement of the exhaust as it rotates in a first direction about the frame hanger. The vehicle may include a second frame bracket having an engaging portion located adjacent to the isolator at a second distance opposite to the first frame bracket. The second distance may define a second maximum allowable displacement of the exhaust as it rotates in a second direction about the frame hanger.

Present disclosure A hydraulic stopping damper includes a cylinder in which a work fluid is stored, a piston rod coupled such that one side of the piston rod is to be inserted into an inner space of the cylinder, and a rod guide through which the piston rod passes and coupled to one side of the cylinder.

The vibration damper is passed through by a transverse center plane, and the vibration damper includes a retention apparatus that can be fixed to a motor vehicle component. In embodiments, the vibration damper has at least two receptors that each have an inner side facing the transverse center plane and an outer side facing away from the transverse center plane, has a damper mass with a central longitudinal axis, and has at least two elastomer springs. In embodiments, the elastomer springs couple the damper mass to the receptors with an ability to vibrate, and at least one of the elastomer springs has a connection portion, between the damper mass and respective receptor, that extends at least mainly externally with respect to the respective receptor.

A propeller shaft assembly includes a propeller shaft extending along an axis between a first and second shaft end. A propeller shaft yoke is operably connected to one of the first or second shaft ends and includes a body presenting a mounting surface extending circumferentially about the axis. A tuned damper extends radially outwardly from the mounting surface and includes a first damper ring disposed in abutting and encircling relationship with the mounting surface and a second damper ring disposed in abutting and encircling relationship with the first damper ring. The tuned damper includes a retention lip extending radially downwardly from the second damper ring in axially spaced relationship with the mounting hub by an axial spacing distance D for protecting the tuned damper from axial impact forces and improving the robustness of the tuned damper mounted on the mounting surface.

A spring element for an upper nipper of a combing machine has a first element with a through opening arranged transversely to a longitudinal axis. A second element has an internal thread for fastening a shaft adapter, and a guide opening with an opening width as well as a passage opening arranged in the longitudinal axis on a side of the guide opening facing away from the internal thread. A compression spring is arranged between the first and second elements. A connecting element is held in the bore of the first element and projects through the passage opening of the second element into the guide opening, the connecting element having a larger diameter than the passage opening on a side thereof opposite the first element. The first element has a tubular lug overlapping the compression spring, and the second element has a sleeve overlapping the compression spring and the lug.

Various embodiments provide a bush for isolating vibrations, the bush comprising: a first anchor part defining a longitudinal axis; a second anchor part disposed coaxially with respect to the first anchor part; a first resilient body operably engaged with the first anchor part; a second resilient body operably engaged with the second anchor part; and an inertial mass element disposed between the first anchor part and the second anchor part.
