Rotary pneumatic actuator with inside protection and manufacturing process thereoff

摘要

Pneumatic actuator wherein the actuator casing is made in plastic reinforced with fibreglass and wherein a protective cylinder is disposed in the inner cavity of the actuator which forms an integral part of the casing forming a single part, for which purpose the cylinder is introduced in the mould during the manufacturing process before injection of the plastic. Thanks to this configuration it resolves the problem of wear of the toric elements housed inside the actuator cylinder.
