Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber.
Rotary actuator. A rotary actuator is an actuator that produces a rotary motion or torque . The simplest actuator is purely mechanical, where linear motion in one direction gives rise to rotation. The most common actuators are electrically powered; others may be powered pneumatically or hydraulically, or use energy stored in springs .
DVD drive with leadscrew and stepper motor. Floppy disc drive with leadscrew and stepper motor. A linear actuator is an actuator that creates linear motion (i.e., in a straight line), in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals ...
Hydropneumatic suspension is a type of motor vehicle suspension system, designed by Paul Magès, invented by Citroën, and fitted to Citroën cars. The suspension was referred to as Suspension oléopneumatique [ fr] in early literature, pointing to oil and air as its main components. [ 1][ 2] The system was also used under licence by other car ...
Pneumatic rack and pinion actuators for valve controls of water pipes. A pneumatic actuator mainly consists of a piston or a diaphragm which develops the motive power. It keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm or piston to move the valve stem or rotate the valve control element.
Actuator. An actuator is a component of a machine that produces force, torque, or displacement, usually in a controlled way, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system ). [ 1] An actuator converts such an input signal into the required form of mechanical energy.
Air (or other gas) pressure is the power source for pneumatic valve actuators. [1] They are used on linear or quarter-turn valves. Air pressure acts on a piston or bellows diaphragm creating linear force on a valve stem. Alternatively, a quarter-turn vane-type actuator produces torque to provide rotary motion to operate a quarter-turn valve.
Simplified diagram. of linear dashpot. A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [ 1] The resulting force is proportional to the velocity, but acts in the opposite direction, [ 2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring.
