ABSTRACT:
The rotary piston power system includes a housing having a drum and a cover rotatably mounted on the drum. The drum has high pressure and low pressure ports defined in its peripheral wall and a central separator wall having arcuate end faces and a pair of semicylindrical recesses defined in opposing sidewalls. A pair of pistons are rotatably mounted on axles on opposite sides of the separator wall and fit closely between the separator wall and the peripheral wall. Each piston has a plurality of radially disposed cylindrical recesses defining slots in the piston's peripheral wall. The cover has a plurality of radially disposed vanes extending into the drum defining a number of cylinders or chambers double the number of recesses defined in a single piston. An input/output shaft extends from the opposite side of the cover for coupling to a prime mover or to a load.
