Actuator Systems

Linear actuators consist of a piston and rod that move within a cylinder. The cylinder has two hydraulic ports; one for extension of the piston and rod and one port for retraction. When hydraulic fluid is directed to the extension port of the actuator, the piston moves to extend the rod out of the cylinder. When hydraulic fluid is directed to the retract port, the piston moves to retract the rod into the cylinder.
The cylinder is “pinned” in two places, one fixed point and one translational point. As the piston rod extends and retracts, the translating point moves with it, providing motion control to accomplish tasks such as deploying thrust reversers or opening and closing doors.
Actuators can be outfitted with locking mechanisms designed to hold the actuator in a desired position. This aids functionality and safety of the actuator. Parker has the capability to design an entire actuation system to meet your project requirements.
Actuation systems incorporate all the necessary elements to keep a system clean and controlled, including filters, valving, and hydraulic lines. Multi-actuator systems, such as those required for thrust reverser applications, can also be synchronized using a shaft and worm gear system which ensures the system works together smoothly and safely.
