ABSTRACT:
The preferred embodiment of the present invention is in the form of a rotary compression/combustion assembly (10) adaptable to be utilized as an internal combustion engine, a fluid pump or as fluid compressor device. The assembly (10) operates by the interaction of a variety of subassemblies, and is formed to be generally symmetrical about a central axis (11). A chamber subassembly (12), of cylindrical shape, is divided into five subchambers (54-62) by four vane subassmeblies (14). Each vane member (44) pivots about its own pivot axis to create a variable volume combustion/compression chamber (54-60) between the vane member (44) and the frame side wall (32) of the cylinder frame (24). A rotor subassembly (16), including a drive shaft (86) and a rotor blade (88) interacts with vane members (44) with the position of the rotor blade (88) determining, or being determined by, depending upon mode of use, the volume of each subchamber (54-60). A port/valve subassembly (18) controls fluid flow and, in combustion mode, an ignition subassembly (20) provides an igniting spark. A vane return mechanism subassembly (22) urges each of the vane members (44) to a position of maximal chamber volume when permitted by the position of the rotor blade (88). The assembly (10) can operate without a required flywheel and is easily assembled and disassembled for economical manufacture, maintenance and repair.
