Abstract
Linear generators with a piston having a valve are described herein. The linear generator includes a combustion module and at least one linear motor. The linear motor includes at least one piston having: a piston head with an opening therein; a piston skirt opposed to the piston head; a piston side wall extending between the piston head and the piston skirt, the piston side wall having at least one port therein. The piston also includes a valve mechanism movable relative to each of the piston head, the piston seat and the piston side wall. The valve mechanism includes a valve stem extending through the piston skirt and the interior piston volume into a mover shaft of the motor, and a valve head coupled to the valve stem and configured to cover the opening of the piston head.
