3.2 HYDRAULIC CYLINDERS (LINEAR ACTUATORS)
Hydraulic cylinders convert flow into linear movement and pressure into force by employing a piston that slides inside a cylinder. The construction of a typical double-acting actuator can be seen in Figure 3.1 that shows the use of appropriate sliding seals for the piston and rod components. The double-acting feature to provide operation in both directions is not always required as in some applications (e.g., fork lift truck systems) the force from the load is used ...
