Abstract
An apparatus may have a cylinder including a piston rod and a chamber in which a working fluid is received to resist movement of the piston rod into the chamber, and an accumulator having a first chamber in communication with the cylinder chamber to receive fluid from the cylinder chamber upon movement of the piston rod into the cylinder chamber. The apparatus may also have a pressure controller having a fluid chamber where some of the working fluid may be received and an actuator operable to increase the volume of the fluid chamber when the piston rod is retracted into the cylinder chamber to increase the total volume in which the working fluid may be received, wherein the increased volume of the fluid chamber may accommodate fluid movement in the assembly not caused by movement of the piston rod.
