A cross-section view of a butterfly valve. In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine ...
The centrifugal pendulum absorber was first patented in 1937 by R. Sarazin [1] and a different version by R. Chilton in 1938. [2] Generally, both Sarazin and Chilton are credited with the invention. Sarazin's work was used during World War II by Pratt & Whitney for aircraft engines with increased power output. The power increase caused an ...
Butterfly valve with actuator electric valve - An electrically actuated butterfly valve is a quarter-turn valve controlled by an electric motor. It offers fast and precise flow regulation, remote operation, and versatility for various applications.
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).
In order to reduce the maximum force on the motor mounts as the motor operates over a range of speeds, a smaller mass, m 2, is connected to m 1 by a spring and a damper, k 2 and c 2. F 1 is the effective force on the motor due to its operation. Response of the system excited by one unit of force, with (red) and without (blue) the 10% tuned mass ...
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 ...
A gas spring consists of a sealed cylinder filled with a charge of high-pressure [5] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
When the aircraft is stationary on the ground, its weight is supported by the compressed gas in the cylinder. [1] During landing, or when the aircraft taxis over bumps, the piston slides up and down. [4] This movement compresses the gas, which acts as a spring, and forces oil through the orifice, which acts as a damper.
