Fire damper. Interior of German mechanical fire damper inside of a galvanised steel duct. Fire dampers (or fire shutters) are passive fire protection products used in heating, ventilation, and air conditioning (HVAC) ducts to prevent and isolate the spread of fire inside the ductwork through fire-resistance rated walls and floors.

A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] and cable-stayed bridges. The dumbbell -shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main ...
Damper (flow) Opposed blade dampers in a mixing duct. A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...
Originally named Allen Manufacturing Company, the business produced hexagonal set screws and wrenches to fasten them. The terms "Allen wrench" (American English) and "Allen key" (British English) [3] are derived from the Allen brand name and refer to the generic product category "hex keys". W.G. Allen [4] filed the first related patent in 1909 ...
Function. The function of a centrifugal pendulum absorber is as with any tuned mass absorbers based on an absorption principle rather than a damping principle. The distinction is significant since dampers reduce the vibration amplitude by converting the vibration energy into heat. Absorbers store the energy and return it to the vibration system ...
Friction disk shock absorbers or André Hartford dampers were an early form of shock absorber or damper used for car suspension. They were commonly used in the 1930s but were considered obsolete post-war. Compared to modern shock absorbers friction dampers only provided limited shock absorption but served mainly to damp down oscillation.
Shock absorber. Miniature oil-filled Coilover shock components for scale cars. A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
www.sram.com. SRAM LLC is a privately owned bicycle component manufacturer based in Chicago, Illinois, United States, founded in 1987. [2] SRAM is an acronym comprising the names of its founders. [2] The company produces a range of cycling components, including Grip Shift, and separate gravel, road, and mountain drivetrains from 7 to 12 speed.
Inertia damper. An inertia damper is a device that counters vibration using the effects of inertia and other forces and motion. [1] The damper does not negate the forces but either absorbs or redirects them by other means. For example, a large and heavy suspended body may be used to absorb several short-duration large forces, and to reapply ...
Blast dampers usually employ some type of blade held open with tension from a spring. The damper blades close automatically when pressure overcomes the resistance offered by the spring. Various models differ in the amount of blast protection (e.g. 1 bar/14.5 psi or lower amounts of protection) and whether they stay closed after the blast or ...
