Beschreibung
Zusammenfassung:	A multiple-stage fluid operated actuator (100) is provided. The multiple-stage fluid operated actuator (100) comprises a housing (101) including a first bore (212) with a first cross-sectional area and a second bore (215) with a second cross-sectional area. The multiple-stage fluid operated actuator (100) further comprises a piston assembly (210) including a first piston (210a) movable within the first bore (212) and a second piston (210b) movable within the first and second bores (212, 215). The piston assembly (210) separates the first and second bores (212, 215) into a first fluid chamber (214a) selectively in fluid communication with a pressurized fluid source (220) or an exhaust, an airtight second fluid chamber (214b), and a third fluid chamber (214c) selectively in fluid communication with the pressurized fluid source (220) or the exhaust.
