Abstract: A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

Abstract: A stand pipe is disposed so as to be fitted with the inner periphery surface of a piston rod with a hollow structure and a reservoir is incorporated into the inside of the stand pipe, whereby it becomes possible to reduce the size of an EHA device. Besides, since the reservoir is separated from both an annulus-side oil chamber and a bore-side oil chamber, a stable reservoir performance can be exhibited without being influenced by a fluid pressure resulting from an external force. Moreover, as a result of installation of the stand pipe, a difference between the amount of fluid required per unit stroke in the annulus-side oil chamber and that in the bore-side oil chamber becomes smaller, so that the required volume of the reservoir oil chamber can be reduced and it is possible to constitute an efficient EHA device with little difference between the energy consumption during compressing and that during extending. Consequently, it is possible to provide a reservoir built-in type actuator capable of exhibiting a stable performance without being influenced by an external force acting on the actuator and capable of attaining the reduction in size of the entire EHA device.

Abstract translation: 立管设置成与具有中空结构的活塞杆的内周面配合，并且将储存器结合到立管的内部，从而可以减小EHA装置的尺寸。 此外，由于储存器与环空侧油室和孔侧油室分离，所以可以显示稳定的储存性能，而不受外力所致的流体压力的影响。 此外，由于安装立管，环形侧油室与孔侧油室的每单位行程所需的流体量之间的差异变小，所以容器的所需体积 可以减少油室，并且可以构成在压缩期间和延伸期间的能量消耗之间几乎没有差异的有效的EHA装置。 因此，可以提供能够显示稳定性能而不受作用在致动器上的外力的影响并且能够实现整个EHA装置的尺寸减小的储液器内置式致动器。

Abstract: A hydraulic cylinder in which the cylinder head contains a motor-driven fluid pump, fluid reservoir, and a main control valve for the cylinder. The cylinder includes a transfer tube that extends through the center of the cylinder's piston and terminates within a hollow ported section of a piston rod. The cylinder head can additionally include two electrically-actuated pilot valves and two pilot-operated check valves. The pilot-operated check valves include structure that, in combination with passages in the cylinder head, cause both pilot-operated check valves to open when pressurized fluid is being directed to one of the pilot-operated check valves by the main control valve.
