  • Publication number: 20140261288
    Abstract: An expansion system utilizes external combustion of its residual warm exhaust air, in order to heat incoming compressed air. The heat of this external combustion is communicated to the incoming compressed air through a heat exchanger. The expansion system may be incorporated into an energy storage device also featuring a compressed air storage unit supplied by a compressor. Where the stored supply of compressed air is depleted, the energy storage device may continue to supply electricity on demand through operation as a heat engine, with the compressor being driven directly (e.g. on a same rotating shaft) or indirectly (via generated electrical power) by the expansion system. Multiple expanders of the same or different types (e.g. rotating, reciprocating), may be utilized in parallel and/or in series (e.g. multiple stages) depending upon the particular application. Multi-stage embodiments featuring internal combustion in low pressure stages, may be particularly suited for placement in vehicles.

The technical result of the invention involves increasing the operational reliability, extending the service life, improving the specific mass and dimensional characteristics and enhancing the effectiveness of a machine. The essence of the invention is that the piston and the crank of a piston machine are interconnected by means of a hinged joint with at least a flat hinge which enables the piston to self-center along the surface of a cylinder owing to the movement of the piston with respect to the crank in any direction on a plane that intersects the longitudinal axis of the cylinder. The surfaces of the crank that take up reactive torque are constricted by rollers with synchronized toothed wheels.

  • Patent number: 8757126
    Abstract: An engine with pistons (7, 8, 67, 68, 69) that follow a circular motion (6) and respective cylinders (11, 15, 77, 78, 79) that follow a counter-circular motion (13, 17) relative to the pistons, such that each piston follows a linear path (S) relative to the respective cylinder, and at least a top surface (8T) of each piston remains within the cylinder throughout engine operation, resulting in a stroke length (S) four times a radius (R) of the circular motion. The pistons may be interconnected by connecting rods (9) without wrist pins, forming a multi-piston assembly (7-8-9, 115) as a single dynamic unit. Intake (110) and exhaust gas passages may go through the crankshaft (20, 20A) and the connecting rod assembly (115) to ports (130, 132) in the tops of the pistons via rotary valves (126, 128) in the connecting rod assembly.
