PNEUMATIC ACTUATOR TECHNOLOGY IPneumatic Actuators n its basic form, a pneumatic actuator is a device which translates the energy from a compressed air supply into a linear or rotary movement. In essence, actuators generally represent the business end of any pneumatic system, providing the means by which specific tasks such asFile Size: KB.

Today, pneumatic technology has a slightly risible air, with pneumatic tubes associated in popular imagination with their key role in Terry Gilliam’s film, Brazil. Few know that in Washington an attempt was made to be at the leading edge of pneumatic technological innovation, or that a utopian socialist inventor/philosopher instigated it.

In this type of device the structure acts as gearbox and buffer. In an oscillating water column type device, the waves cause a reciprocating air flow through a pneumatic power take-off as shown in Figure The large surface area of the water surface in comparison to the annular area of a turbine produces the gearing-up of velocities, from low water surface velocity to much faster air.
