摘要： A partition member of an anti-vibration hydraulic mount includes a first channel and a second channel between the working chamber and the compensating chamber. The partition member includes a membrane secured in a receiving cavity. The membrane divides the receiving cavity into two sub-spaces separated fluidically from each other. The membrane comprises a closing device configured to have an open configuration, in which the closing device is spaced apart from the central opening, and a closed configuration, in which the closing device abuts against the central opening to close the central passageway.

摘要： A hydraulic vibration damper may include inner and outer tubes filled with damping liquid, a piston rod projecting axially out of the inner tube and movable in rebound and compression directions, a sealing and guide pack that sealingly closes an end of the outer tube and guides piston rod movement, a working piston for producing damping forces that is fastened to the piston rod and is guided on an inner lateral surface of the inner tube and subdivides the interior of the inner tube into a piston rod-side and piston rod-remote working spaces. The vibration damper has rebound and compression stops. In the piston rod-remote working space, a compression stop, starting from a predetermined retraction travel of the piston rod, may produce a travel- and speed-dependent compression stop force.

摘要： A shock absorber includes i) a hollow base defining an axial direction and having a first mounting portion, ii) an outer axial tube, having first and second longitudinal ends, and being coaxially mounted into the hollow base via its first longitudinal end so as to allow adjusting a distance of the second longitudinal end relative to the base; and iii) an inner axial tube slidably mounted into the outer axial tube therein; the inner axial tube having a second mounting portion. The hollow tube has an opening therein that defines a window to allow visualizing a part of the outer axial tube therethrough which includes the first longitudinal end thereof.

摘要： A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).
