Abstract
Reciprocally moving an output rod mounted to a force transfer member includes applying hydraulic pressure to a first piston and cylinder device to operate the first piston and cylinder device in compression to move the force transfer member in a first direction; applying hydraulic pressure to a second piston and cylinder device to operate the second piston and cylinder device in compression to move the force transfer member in an opposite second direction; refraining from applying tension to the second piston and cylinder device while applying hydraulic pressure to the first piston and cylinder device; and refraining from applying tension to the first piston and cylinder device while applying hydraulic pressure to the second piston and cylinder device.
