Hydraulic Actuators
Written by Super UserHydraulic actuators
A cylinder or fluid motor that converts hydraulic power into useful mechanical work
The mechanical motion produced may be linear, rotary, or oscillatory.
Operation exhibits high force capability, high power per unit weight and volume, good mechanical stiffness, and high dynamic response.
These features lead to wide use in precision control systems and in heavy-duty machine tool, mobile, marine, and aerospace applications.

PRINCIPLE OF OPERATION
Counter clockwise output operation is achieved by inserting pressure into Port 'A', to force the pistons apart thus rotating the actuator pinion counter clockwise.
During this operation, air from the outer chambers is exhausted through Port 'B'. Clockwise output operation is achieved by reverse of the above and inserting pressure into Port 'B'.
