  • Rotary engine with rotary power heads
    Patent number: 9273556
    Abstract: A rotary engine includes a casing having a first circular boring and a second circular boring smaller than the first circular boring. The first circular boring interconnects with the second circular boring. A piston rotor can move in a rotating manner within the first circular boring in the casing. A power head, ported to pass exhaust gases through a hollow center shaft, can move in a rotating manner within the second circular boring in the casing. The piston rotor and the power head can be coupled via a gear system to properly rotate during operation, with the piston rotor rotating counterclockwise and the power head rotating clockwise, or vice versa.

  • Rotary engine with rotary power heads
    Patent number: 8967114
    Abstract: A rotary engine includes a casing having a large circular boring, a small circular boring, whereby the small circular boring interconnects with the large circular boring. A piston rotor is carried in a rotating manner within the large circular boring in the casing. A power head, ported to pass exhaust gases thru it's hollow center shaft, is carried in a rotating manner within the small circular boring in the casing. The piston rotor and the power head are meshed together to properly rotate during operation, with the piston rotor rotating counterclockwise and the power head rotating clockwise. A second powerhead can also be used.
