Abstract

Gas driven motors are presented including: a housing defining a circulation chamber and a shutter chamber, where the housing includes an intake port and an exhaust port; a drive axle positioned along a pair of parallel circulation chamber walls and rotatably attached thereto, where the drive axle is perpendicular to the pair of parallel circulation chamber walls; a vane having an attached edge, a leading edge parallel with and opposite to the attached edge, and a pair of vane side edges, where the pair of side edges are parallel with respect to one another and form a matching curve with respect to one another, where the vane includes a curved surface defined by the pair of side edges, where the vane is mechanically coupled with the drive axle along the attached edge.

Abstract

A drive mechanism for a vehicle is disclosed, said drive mechanism converting the reciprocating clockwise-counterclockwise motion of an input shaft into continuous rotation of an output shaft by means of two one-way clutches mechanically coupled to the input shaft and the output shaft, said one-way clutches having their power stroke in opposite directions of rotation. In an embodiment, said drive mechanism can be contained in a wheel hub and used for human-powered vehicles such as scooters, bicycles, wheelchairs, rollerskates, or other vehicles.
