Abstract
A free-piston variable stroke linear-alternator AC power generator for a combustion engine. An alternator mechanism and oscillator system generates AC current. The oscillation system includes two oscillation devices each having a combustion cylinder and a flying turnbuckle. The flying turnbuckle moves in accordance with the oscillation device. The alternator system is a linear alternator coupled between the two oscillation devices by a slotted connecting rod.
Claims20
A free piston variable stroke generator comprising:
- oscillating means for obtaining a variable stroke;
- alternator means for generating electric current in accordance with the variable stroke from said oscillating means;
- and
- turnbuckle means connected to said oscillating means for obtaining a variable stroke.
A free-piston variable-stroke generator comprising:
- two systems moving in opposing directions, each said system including:
- two internal combustion cylinders;
- two sliding exhaust-port sleeves respectively coupled to said internal combustion cylinders;
- two pistons respectively connected to said two sliding exhaust-port sleeves;
- and
- two connecting rods having a first end respectively connected to said two pistons;
- two turnbuckles, respectively connected to a second end of said two connecting rods, said two turnbuckles oscillating with said two pistons, respectively;
- a linear alternator coupled between said two turnbuckles and including a plunger, said two pistons being rigidly attached to each side of said plunger through said respective two turnbuckles;
- and
- means connected to said linear alternator for providing AC output power.
A free piston variable stroke generator, comprising:
- an alternator operatively connectable to provide a demanded electric power output;
- an oscillator having a variable stroke and being connected to drive said alternator so that the variable stroke varies in response to the demanded electric power output.
