A device subject to US patent US2917063 A.
a flapper and. nozzle arrangement of a pneumatically operated mechanism.
In this work, a Pneumatic Nozzle Flapper is built and simulated. This device is used to stimulate a mechanical force that is applied at the same time to an array of cantilevers that needs to be pushed mechanically. A thermal microactuator functions as a flapper for the pneumatic system allowing same amount of force to be applied at the same time to all cantilevers. Simulation shows that the idea is feasible and can work at the micro scale. Finite Element Analysis is provided for the pneumatic structure and the electrothermal microactuator.
In a flapper nozzle, the flow rate of the fluid passing through is directly proportional to the difference in pressure across the nozzle. As the pressure increases, the flow rate also increases. This relationship between pressure and flow rate is governed by equations such as Bernoulli's principle and the equation of continuity.

Before going into the calibration process, it is important to understand the design of a positioner assembly. The following pointers will help you understand it better. The positioner assembly of a control valve consists of a flapper-nozzle, cam linkage, summing beam, and spring and a diaphragm interlinked together with the help of mechanical linkages. The summing beam is connected between the cam-spring linkage and the bellow. The action of cam-spring is directed by the pressure applied by the flapper-nozzle, which eventually triggers the motion of the summing beam. The diaphragm displays the applied and exerting pressure on/by the flapper assembly.
erm.... Pneumatic Drill Pneumatic Cylinder Pneumatic Actuator Pneumatic Switch Pneumatic Nailgun Pneumatic Air gun Pneumatic Launcher Bit more than four, but now you can choose, hope this helps,
flapper
The duration of The Flapper is 1.47 hours.
Car tyres, balloons, whoopee cushions. Pneumatic jacks. Pneumatic clamp. Pneumatic drills. Pneumatic door. Pneumatic wrench.
Pneumatic - as in pneumatic drill or pneumatic cannon is the correct spelling
The "flapper in the throat" is called the epiglottis.
The Irresistible Flapper was created in 1919.
The Perfect Flapper was created in 1924.
