摘要： A hydraulic external heat source engine wherein energy is supplied to a working end space of the engine by direct application of pressurized and heated liquid working fluid to the piston within a cylinder. The power stroke utilizes expanded hot liquid as the primary pressure source. After fluid intake cut-off, some of the heated liquid spontaneously vaporizes, thereby continuing to drive the working piston. The exhaust liquid working fluid discharged from the cylinder is recycled to an external preheat exchanger for preheating cold compressed working fluid expelled from the pump end space of the engine. The majority of the vapor produced within the cylinder recondenses within the cylinder and is discharged as liquid. The small amount of vapor that is discharged from the cylinder is condensed in an expansion chamber in the preheat exchanger. The preheated fluid is heated to operating temperature and pressure in a primary heat exchanger before being recycled into the working end space. The cooled exhaust fluid in the preheat exchanger is passed through a cold reservoir exchanger for further cooling before introduction into the pump end space. The engine is large and is well suited to stationary applications using low-grade heat sources such as solar, geothermal, and waste heat to supply heat to primary heat exchanger.
摘要翻译： 一种液压外部热源发动机，其中通过将加压和加热的液体工作流体直接施加到气缸内的活塞而将能量供应到发动机的工作端部空间。 动力冲程使用膨胀热液体作为主要压力源。 在进液截止后，一些加热液体自发蒸发，从而继续驱动工作活塞。 从气缸排出的排气液体工作流体被再循环到外部预热交换器，用于预热从发动机的泵端空间排出的冷压缩工作流体。 气缸内产生的大部分蒸汽在液压缸内再生，并作为液体排出。 从汽缸排出的少量蒸汽在预热换热器中的膨胀室中冷凝。 在再次进入工作终端空间之前，预热的流体在主换热器中被加热到工作温度和压力。 预热换热器中的冷却废气流体通过冷库交换器进行进一步冷却，然后引入泵的末端空间。 发动机很大，非常适用于使用低等级热源（如太阳能，地热和余热）的固定应用，以向主热交换器供热。

摘要： A rotary external combustion engine wherein energy is transferred to air acting as a working gas by injection into the air of liquid water at a high temperature and pressure. The liquid water is injected either directly into the working space in the stator or into a preliminary mixing chamber. The water acts as a heat-transfer medium for heating the air. Spontaneous vaporization of the liquid water on injection increases the pressure of the air which drives the rotor before being exhausted. The exhaust water is recovered and recycled. The working space is scavenged and refilled with a fresh charge of air.

摘要： A reciprocating external combustion engine wherein energy is supplied to a working end space of the engine by direct injection into the cylinder 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, driving the piston. Liquid water is exhausted from the cylinder 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.
