摘要： An energy storage device particularly suitable for use in hybrid fluid power systems and fluid systems utilizing accumulators. A piston accumulator has a primary face on one end of the piston and a series of secondary faces on the opposite end of the piston. Each face has an associated chamber, and one or more of the chambers of the secondary faces may be selectively connected to a system pressure line. Since the pressure of the system pressure line depends on (and varies with) the number of chambers connected thereto, the potential energy of the chamber of the primary face may be delivered to the system pressure line at a variety of output pressures. Similarly, the chamber of the primary face may be recharged with energy at a variety of input pressures.
摘要翻译： 特别适用于混合流体动力系统和利用蓄能器的流体系统的储能装置。 活塞蓄能器在活塞的一端具有初级面，在活塞的另一端具有一系列次表面。 每个表面都具有相关联的腔室，并且次表面的一个或多个腔室可以选择性地连接到系统压力线。 由于系统压力线的压力取决于连接到其上的室的数量（并且随其变化），所以主表面腔的势能可以以各种输出压力被输送到系统压力管线。 类似地，初级面的腔室可以以各种输入压力的能量进行再充电。

摘要： An internal combustion engine utilizing hypocycloid movement has a crankshaft having a small crank pin construction wherein the piston rod end is supported rotatably on an eccentric disc which, in turn, is journalled for rotation on the crankpin. A rigid interconnected subassembly of the eccentric disc, counterweights and a pinion gear is rotatably mounted on the crankpin in a manner to distribute the piston loads to the opposite pin ends, thereby reducing crankpin bending stresses. The main crankshaft support bearings are located directly adjacent the crankpin ends, thereby further reducing crankpin bending stresses. A two-piece crankshaft construction allows the crankshaft to be preassembled for machining, disassembled for mounting the piston subassembly thereon, and reassembled. The modified hypocycloid gearing assembly includes a rotatable internal ring gear transmitting a portion of the torque produced by the piston force to the output shaft via the pinion gear and an idler gear and sun gear assembly. The remaining portion of the torque produced by the piston force is transmitted directly through the crankshaft. An adjustable idler gear mounting allows the modified gear assembly to be adjusted to compensate for gear tooth backlash.
摘要翻译： 利用次摆线运动的内燃机具有具有小曲柄销结构的曲轴，其中活塞杆端可旋转地支撑在偏心盘上，该偏心圆盘又被转动支承在曲轴销上。 偏心盘，配重和小齿轮的刚性互连子组件以将活塞负载分配到相对的销端的方式可旋转地安装在曲柄销上，从而减小曲柄销弯曲应力。 主曲轴支撑轴承直接位于曲柄销端部附近，从而进一步减小曲柄销弯曲应力。 两件式曲轴结构允许将曲轴预组装用于机械加工，拆卸以将活塞组件安装在其上并重新组装。 改进的下摆线圈齿轮组件包括可旋转的内齿圈，其将由活塞力产生的扭矩的一部分经由小齿轮传递到输出轴，以及惰轮和太阳齿轮组件。 由活塞力产生的扭矩的剩余部分直接通过曲轴传递。 可调节的空转齿轮安装允许修改的齿轮组件被调节以补偿齿轮齿隙。
