    摘要： The invention relates to a thermodynamic circuit process device comprising a working medium having a lubricant additive; an expansion machine (5) for converting enthalpy in the working medium into mechanical energy; a multi-stage pressure-increasing apparatus (1) for the step-by-step pressurization of the working medium; a means (4) for branching a part of the working medium between two stages of the multi-stage pressure-increasing apparatus (1); and a means (4) for feeding the branched off part of the working medium to one or a plurality of bearing points of the expansion machine. The invention further relates to a corresponding method for lubricating an expansion machine in a thermodynamic circuit process device.

    摘要： A compression vapor engine which, being at its core a cylinder and piston, the latter attached to a rotary wheel, moves the piston to compress air, thereby heating it; introduces water to the compressed air, converting it from liquid to vapor, water to steam; and uses the expanding steam to move the piston reciprocally: all organized as a reciprocal cylinder-piston engine creating continuing rotary movement which can be made to do work.

    摘要： An Advanced Uniflow Rankine Engine (“AURE”) that is effective and thermodynamically efficient at higher speeds (e.g., 400-1800 rpm) and has low torque output. This allows the AURE to be compact of size without the need for a massive foundation found in prior art steam engines. The AURE includes an admission valve assembly, a cylinder head/valve gear assembly, a cylinder/piston assembly, a crank shaft assembly, an external sump, and an integral condenser. The admission valve assembly includes a counterbalancing poppet valve and valve stem that creates counterbalanced unsupported areas that allow the poppet valve to operate at higher speeds. The AURE can be fueled by raw, unprocessed fuel, including biomass, to generate efficient energy in a smaller overall package.

    摘要： A rotary external combustion engine wherein energy is supplied to a working space of the engine by direct injection into the stator of liquid water at a high temperature and pressure. The water acts as a heat-transfer medium. Some of the liquid water spontaneously vaporizes on injection, during the rotor. Liquid water is exhausted from the working space and recycled to an external heat exchanger for reheating prior to reinjection. The engine is capable of a thermal efficiency greater than that of the Rankine cycle.

    摘要： An improved heat engine that includes an organic refrigerant exhibiting a boiling point below −35° C.; a heat source having a temperature of less than 82° C.; a heat sink; a sealed, closed-loop path for the organic refrigerant, the sealed, closed-loop path having both a high-pressure zone that absorbs heat from the heat source, and a low-pressure zone that transfers heat to the heat sink; a positive-displacement decompressor providing a pressure gradient through which the organic refrigerant in the gaseous phase flows continuously from the high-pressure zone to the low-pressure zone, the positive-displacement decompressor extracting mechanical energy due to the pressure gradient; and a positive-displacement hydraulic pump, which provides continuous flow of the organic refrigerant in the liquid phase from the low-pressure zone to the high-pressure zone, the hydraulic pump and the positive-displacement decompressor maintaining a pressure differential between the two zones of between about 20 to 42 bar.
