  2. Butterfly valve - Wikipedia

    en.wikipedia.org/wiki/Butterfly_valve

    A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. Principle of operation

  3. Shock absorber - Wikipedia

    en.wikipedia.org/wiki/Shock_absorber

    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. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).

  4. Harmonic damper - Wikipedia

    en.wikipedia.org/wiki/Harmonic_damper

    A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and ...

  5. Damper (flow) - Wikipedia

    en.wikipedia.org/wiki/Damper_(flow)

    This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...

  6. Damping torque - Wikipedia

    en.wikipedia.org/wiki/Damping_torque

    Damping torque is provided by indicating instrument. Damper is a generic term used to identify any mechanism used for vibration energy absorption, the shaft vibration suppression, soft start and overload protection device. In order to design an efficient damper, it is imperative that the damping torque is calculated first.

  7. Centrifugal pendulum absorber - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pendulum_absorber

    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 at the appropriate time. [5] Centrifugal pendulum absorbers like tuned mass absorbers are not part of the force/torque flow.

  8. Inertia damper - Wikipedia

    en.wikipedia.org/wiki/Inertia_damper

    Rotary damper - rotary motion is dissipated as heat in a highly viscous fluid or gel. May use a smooth surface rotating cylinder and a smooth surface stationary interior wall with fluid/gel between. For more forceful motion absorption and higher surface area, a paddle wheel or toothed gear is used, with a similarly ribbed or studded stationary ...

  9. Diaphragm valve - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_valve

    Rubber Lined Diaphragm Valve. Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve.
