    Abstract: A pneumatic actuator and control valve assembly has a housing with a control cavity for a control valve and an actuator cavity for an actuator piston and rod assembly. The control cavity and actuator cavity both have an elongated shape and are substantially parallel to each other. The control cavity has a supply port and first and second control valve outlet ports and at least one vent port with the control valve being movable through the control cavity for controlling communication between the supply port and the first and second outlet ports. The actuator cavity has first and second ports at the retracted and extended ends for shuttling the piston and within the actuator cavity between a retracted and extended end position. The housing has a first inlet and second inlet for passage of pressurized fluid to and from the housing.

    Abstract: 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.

    Abstract: A braking actuator uses a single cylinder without using a spring to achieve a 3-position operation. A partition plate and an intermediate check plate are affixed within a cylinder at suitable intervals in the axial direction. Inserted movably in the axial direction of the cylinder are a first piston disposed between a pressing lid and the intermediate check plate, a second piston disposed between the intermediate check plate and the partition plate, and a third piston disposed between the partition plate and a pressing lid. A rod which is axially movable within the cylinder has a base end attached to the third piston and a tip end which extends outside from the cylinder through the partition plate, the second piston, the intermediate check plate, the first piston, and the pressing lid. A stopper affixed to a middle portion of the rod moves the first piston or the second piston.

    Abstract: In a fluid-operated drive for a field device, the drive being designed to set a control valve of the field device, a fluidically operated basic drive is provided with a basic working chamber loaded fluidically and delimited by a basic drive housing part and by a basic actuating piston guided in the basic drive housing part. At least one supplementary drive is provided with a supplementary working chamber loaded fluidically and delimited by a supplementary drive housing part. The basic drive housing part and the supplementary drive housing part are displaceable in one another in accordance with a piston and chamber arrangement so that a volume of the supplementary chamber changes in the event of a relative movement of the drive housing parts.

    Abstract: A hydraulic actuator is adapted to drive a spoiler of a wing having a flap. When the hydraulic actuator drives the spoiler in an overlapping region where a driving range of the flap and a driving range of the spoiler overlap, an output suppressing structure suppress a drive output of the hydraulic actuator in the overlapping region to be less than that in a non-overlapping region other than the overlapping region.
