Abstract:
1. A pneumato-mechanical regenerative power source, comprising: a. a first support structure; b. a planetary gear system, comprising: c. a first roller-clutch mechanism, comprising: d. a first actuator operatively associated with said first annular support structure so as to provide for positioning said first annular support structure in either said first rotational position or said second rotational position relative to said first support structure; e. a first overrunning clutch mechanism operative between said sun gear or a first element operatively coupled thereto and said ring gear or a second element operatively coupled thereto, wherein said first overrunning clutch mechanism provides for said one of said sun gear or said ring gear to rotate in a first rotational direction relative to the other of said sun gear or said ring gear, and said first overrunning clutch mechanism provides for said other of said sun gear or said ring gear to drive said one of said sun gear or said ring gear when said other of said sun gear or said ring gear is rotated in said first rotational direction; f. a ball-screw mechanism comprising a ball screw and a ball nut, wherein one of said ball screw or said ball nut is operatively coupled to said other of said sun gear or said ring gear so as to rotate therewith; g. a piston operatively coupled to the other of said ball screw or said ball nut, wherein a rotation of said one of said ball screw or said ball nut responsive to a rotation of said other of said sun gear or said ring gear causes a translation of said piston relative to said first support structure; h. a piston cylinder operatively coupled to or a part of said first support structure, wherein said piston is configured to translate within said piston cylinder, said piston is sealed to a cylinder bore of said piston cylinder, said piston and said piston cylinder define at least one region within said piston cylinder on a first axial side of said piston, said at least one region within said, piston cylinder is sealed relative to an environment thereof, and a rotation of said other of said sun gear or said ring gear in a second rotational direction opposite to said first rotational direction coupled to said ball-screw mechanism causes a translation of said piston within said piston cylinder to as to cause a reduction in a volume of said at least one region within said piston cylinder; and i. at least one anti-rotation pin operative between said piston cylinder and said other of said ball screw or said ball nut so as to prevent a rotation of said other of said ball screw or said ball nut relative to said piston cylinder.
