Pneumatic cylinder

Pneumatic cylinder, also known as air cylinder, is a <a href="/facts/Mechanical_device/wTCxFRfs">mechanical device</a> which uses the power of compressed gas to produce a force in a reciprocating linear motion.: 85 
Like in a <a href="/facts/Hydraulic_cylinder/IxeMnFCy">hydraulic cylinder</a>, something forces a <a href="/facts/Piston/z7pN46u7">piston</a> to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. : 85  Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage.
Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney <a href="/facts/Tiki_Room/BLukYrVh">Tiki Room</a>, pneumatics are used to prevent fluid from dripping onto people below the puppets.
