1. A rotary actuator with a spur pinion and rack arrangement comprising of: two pistons, each of the piston integrally connected to a rack, such that linear motion of each of said piston converts into a rotary motion in a pinion, the pinion and the racks being of dissimilar materials, said racks being of lighter and weaker material with respect to said pinion; wherein the improvement comprises said pinion consisting of twelve involute teeth and positively corrected, meshing on said racks of involute teeth and with a root strengthening and equally negatively corrected, and further the racks have a composite involute profile of teeth.
