ABSTRACT:
A fluid actuator including at least two cylinders connected to a common pressurized-fluid supply mechanism. Actuation units are connected to piston rods of the cylinders, respectively. The piston of one of the cylinders is operated by pressurized fluid, and when the piston is moved back, the pressure in the cylinder is increased to operate the piston of the other cylinder. The actuation units are thus operated with a certain amount of interval of time or in a synchronous mode.
