ABSTRACT:
The invention pertains to rotary volumetric apparatus comprising a stationary framework and a rotary assembly mounted thereon. The rotary assembly includes a rotary shaft. The apparatus further includes a reciprocating drive engine and a driven member connected to the rotary shaft. A linkage system drivingly connects the driven member to the engine for rotation in a first direction upon reciprocating movement of the engine in a first directional mode and for rotation in a second direction opposite the first direction upon reciprocating movement of the engine in a second directional mode opposite the first mode. A clutch interconnects the driven member and the shaft and is operative upon rotation of the driven member in the first direction to cause rotation of the shaft therewith, and upon rotation of the driven member in the second direction, to permit relative rotation between the driven member and the shaft, whereby the shaft is rotated by the drive engine in temporally spaced increments.
