  • Axially rotating free piston
    Patent number: 9163504
    Abstract: A piston slidably engaged in relation to the longitudinal axis of a shaft rotationally journaled proximate opposed ends to a housing which allows reciprocal travel of the piston within a cylinder of the housing with the external surface of the piston and the internal surface of the cylinder providing mated portions of a piston rotation generation assembly which induces rotation of the piston within the cylinder during reciprocal travel of the piston along the length of the shaft with the piston having rotationally fixed engagement with the shaft such that rotation of the piston within the cylinder generates a corresponding rotation of the shaft.
    Type: Grant
