    Abstract: A pressure amplifier (1) is described comprising a housing (2), an amplification piston (5) in the housing (2) having a high pressure area (9) in a high pressure chamber (5) and a low pressure area (8) in a low pressure chamber (3), and a switching valve (11) having a pressured control valve element having a larger pressure area (16) and a small pressure area (17). Such a pressure amplifier should have a high operating frequency. To this end the valve element (10) and the amplification piston (5) are located in a same bore (3, 4) in the housing (2).

    Abstract: A hydraulic charging and driving system (4), aircraft employing the same, and corresponding methods, for extending and retracting a hydraulic actuator (2), comprising: a motor assembly (22); and an accumulator assembly (20), the motor assembly (22) and the accumulator assembly (20) being hydraulically coupled to each other; wherein the motor assembly (22) is arranged to recharge the accumulator assembly (20) with hydraulic fluid at a relatively slow rate that is slower than the rate at which the accumulator assembly (20) is arranged to discharge when actuating the hydraulic actuator (2). The system may further comprise a selector valve (24). The accumulator assembly (20) may comprise an accumulator chamber (30), and a compression means (32) provided within the accumulator chamber (30). The motor assembly (22) may comprise a motor (42) arranged to vary a volume of a hydraulic charging chamber (38) of the motor assembly (22).

    Abstract: There is set forth herein an actuator having a housing and a piston assembly. The piston assembly can have a piston and a piston rod extending from the piston. In one embodiment, the housing can receive the piston and a portion of the piston rod. The piston assembly can define a piston assembly interior and a fluid reservoir can be located within the piston assembly interior. A chamber region within the interior of the housing can be separated by the piston assembly to define a piston side chamber and rod side chamber. The piston assembly can be moveable so that respective volumes of each of the piston side chamber and the rod side chamber are variable. For operation of the actuator by movement of the piston assembly within the interior of the housing, fluid can be moved between the reservoir and the chamber region.

    Abstract: An example embodiment includes a hydraulic hybrid system. The hydraulic hybrid system includes a hydraulic system, an energy source configured to produce primary kinetic energy, an output configured to receive at least a first portion of the primary kinetic energy, and a transmission coupled between the energy source and the output and selectively coupled to the hydraulic system. The hydraulic system includes a reservoir, a sequenced accumulator assembly, and a hydraulic pump/motor that is hydraulically coupled to the reservoir and the sequenced accumulator assembly and configured to charge the sequenced accumulator assembly when mechanically driven. The sequenced accumulator assembly includes two or more accumulators, one or more sequence valves, and one or more check valves. The sequenced accumulator assembly is configured to store varying amounts of potential hydraulic energy by introducing and removing one or more of the accumulators from operation.
