  • Variable displacement and/or variable compression ratio piston engine
    Patent number: 4077269
    Abstract: Variable displacement and/or variable compression ratio reciprocating piston engine, for example, an internal combustion engine, having piston and drive shaft essentially parallel to one another with a swash plate mounted on the drive shaft and a connection between the piston and the swash plate. The mounting of the swash plate permits variation of the angle to the drive shaft to vary the piston stroke and also permits movement of the swash plate along the axis of the drive shaft to exercise control over the compression ratio.
