A system for recovering the energy from atmospheric wind wherein a windmill operates a compressor for compressing air which is stored in one or more tanks. The compressed air is used to drive a prime mover coupled by gear means to an electrical generator or other work-producing apparatus. The prime mover is operated by hydraulic fluid responsive to the application of the compressed air to fluid tanks by valve means responsive to the operation of the prime mover. The compressor has a unique means for lubricating the same. Alternatively, the prime mover can be operated by conventional water pressure during periods of little or no wind.

The prime mover is operated by hydraulic fluid responsive to the application of the compressed air to fluid tanks by valve means responsive to the operation of the prime mover. The compressor has a unique means for lubricating the same. Alternately, the prime mover can be operated by conventional water pressure during periods of little or no wind.

A fluid actuated power device which includes a reciprocal cylinder rotatably mounted on a central, tubular shaft for back-and-forth movement along the shaft between a pair of end support members. The cylinder has first and second sets of spiral grooves on its outer surface, the first set of spiral grooves being in mesh with the spiral teeth of a first ratchet gear and the second set of spiral grooves being in mesh with the spiral teeth of a second ratchet gear, the ratchet gears being carried by a cylindrical body fixed relative to the shaft. The ratchet gears permit the cylinder to rotate only in one direction relative to and about the shaft as the cylinder moves back and forth along the length of the shaft. The cylinder is coupled by spline means to a gear assembly which, in turn, is connected to a rotatable second shaft, the latter serving as a power takeoff means which can be connected to external work-producing apparatus. A piston within the cylinder and rigid to the central part of the first-mentioned shaft allows a fluid under pressure to be alternately applied to the two chambers of the cylinder on opposite sides of the piston to thereby cause the back and forth movement of the cylinder relative to the shaft.
