Abstract
Systems, methods and devices for optimizing bi-directional piston movement within a device or system used to compress and/or expand a gas, such as air, are described herein. In some embodiments, a compressed air device and/or system can include a first pneumatic cylinder, a second pneumatic cylinder, a hydraulic actuator, and a hydraulic controller. The first pneumatic cylinder has a first working piston disposed therein for reciprocating movement in the first pneumatic cylinder and the hydraulic actuator is coupled to the first working piston. The second pneumatic cylinder has a second working piston disposed therein for reciprocating movement in the second pneumatic cylinder. The hydraulic controller is fluidically coupleable to the hydraulic actuator and is operable in a compression mode and an expansion mode.
