摘要： A combined hydraulic and pneumatic actuation system (10) including a cylinder (12), a first piston (22), and a second piston (24). The cylinder may include a first cylinder portion (36) configured to hold or retain a first fluid and a second cylinder portion (38) configured to hold or retain a second fluid. The first piston can be operatively coupled or in fluid communication with the first fluid, and the second piston can be operatively coupled or in fluid communication with the second fluid. The second piston may be disposed between the first cylinder portion and the second cylinder portion. In an embodiment, the first piston can move or translate axially within the cylinder independently of the second piston, and an increase in pressure in the second cylinder portion can actuate the first piston and the second piston. Further, in embodiments, the first fluid can comprise a liquid, and the second fluid can comprise a gas.
摘要翻译：包括气缸（12），第一活塞（22）和第二活塞（24）的组合的液压和气动致动系统（10）。气缸可包括构造成保持或保持第一流体的第一气缸部分（36）和构造成保持或保持第二流体的第二气缸部分（38）。第一活塞可以可操作地联接或与第一流体流体连通，并且第二活塞可以可操作地联接或与第二流体流体连通。第二活塞可以设置在第一气缸部分和第二气缸部分之间。在一个实施例中，第一活塞可独立于第二活塞而在气缸内轴向移动或平移，并且第二气缸部分中的压力增加可致动第一活塞和第二活塞。此外，在实施例中，第一流体可以包括液体，并且第二流体可以包括气体。
