Abstract
An air powered motor 10, mounted inside an outer cover 11 to effect the movement of a mirror 12 in one or more axis 35. The pneumatic motor is coaxial with a threaded and pivoted rod 13 and contains a rotor or ring gear 14 with vanes 15 arrayed around the exterior of the gear. Pressurized air is introduced into the motor, against the vanes 15, causing a center piece or gear 16 to rotate about the operating rod 13 attached to a mirror mounting plate 17. As a result, the mirror rotates on its hinge 18. The direction of air flow from the fluid source can be reversed with a control valve, causing the mirror to rotate in the opposite direction. The mirror's rotation about its axis is controlled from a remote location, such as the cab of a large truck, by moving the air control valve.
