    摘要: An internal combustion engine comprises a cylinder of stepped configuration having a working portion and a pumping portion and a piston of stepped configuration having a working portion and a pumping portion, the working and pumping portions respectively co-operating to define a combustion chamber and a pumping chamber each of which varies in volume upon reciprocation of the piston in the cylinder. Air is admitted to the pumping chamber through a duct from where, on volume reduction thereof, if passes via a plurality of passages and a one-way valve into a transfer chamber. On volume expansion of the combustion chamber, air in chamber is discharged therefrom via a plurality of passages, common discharge port and valve to scavenge the combustion chamber and provide combustion air. The valve may be self-acting or operated by a crankshaft controlled push-rod. A delivery pump operated pneumatically under the influence of the pumping chamber to deliver fuel or a combustible mixture to inlet passage is also disclosed.

    摘要: An improved two-cycle internal combustion engine with a novel intake, exhaust and piston arrangement in which a fresh charge for combustion is advantageously transferred through the piston and all valves in the engine operate in response to changes in dynamic pressure generated within the engine. The piston includes at least one charging passage through its top surface with a pressure sensitive valve affixed to the top surface of the piston for preventing flow of a fresh charge through the charging passage in the absence of a greater pressure differential caused by the intake charge against the undersurface of the pressure sensitive valve. Advantageously, the pressure sensitive valve is deflected upwardly to provide passage of a charge through the charging passage in the presence of a sufficient pressure differential caused by the intake charge against the undersurface of the pressure sensitive valve, and the charging passage and pressure sensitive valve coact to direct flow of the incoming charge toward the walls of the engine cylinder away from the exhaust. Also advantageously, the intake and exhaust can be directly controlled by the piston.

    摘要: 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.

    摘要: The invention provides a piston which allows pressure generated downstream from the piston to be used to ventilate a combustion chamber of a cylinder in which the piston is slidingly mounted. The crank assembly to which the piston is connected is operable outside of the cylinder which is sealed at both ends. The crank assembly uses eccentric motion to allow a connecting rod which extends between the piston and the crank assembly to move linearly into and out of the cylinder in sealed manner. The piston includes a valve which allows pressurized gas to flow through the piston.
