Abstract:
Described is an electrically actuated, pneumatic driven motor. The pneumatic driven motor includes a body having first and second surfaces, the body having a chamber defined by an interior wall, a displacement cavity, and a passage that fluidly couples the displacement cavity to the chamber, a bleeder port and a bleeder port passage that fluidly couples the bleeder port to the chamber, a valve disposed in the passage between the displacement cavity and the chamber, an annular pushrod mechanism coupled to the valve, the annular pushrod mechanism having a pair of pawls that protrude from an inner surface of the annular pushrod mechanism, an axle disposed in the chamber; and a motor gear disposed about the axle, the motor gear having a plurality of teeth that selectively engage with the pawls on the pushrod mechanism according to displacement of the annular pushrod mechanism.
