ABSTRACT:
An axial vane rotary power device comprises a rotor arranged to turn within an annular chamber having two end plates with mutually facing undulating cam surfaces. Vanes retained in angularly spaced slots in the rotor reciprocate axially as the rotor turns. Transfer passages, interleaved between the vanes, connect each working chamber to a respective transfer port at the central bore of the rotor. A tubular inner stator member, about which the rotor turns, has two sets of peripheral ports that provide fluid communication between the working chambers and intake and exhaust channels as the rotor turns. Various configurations of the device allow it to function as either a two- or four-phase internal combustion engine, a fluid driven motor, a pump, a compressor or an expander.
