Abstract

A pneumatic servo drive has a servo head to which the pneumatic ram is attached and with a servo arm which pivots between two end positions. A rotating drive shaft protrudes from the head and is powered by the ram. The drive shaft has a non circular head which locates into a non circular flange fitted to the servo arm, to drive the arm with a twist and slide action.
