ABSTRACT:
A system in which movement of a first member from a first position to a second position is translated through fluid in a fluid chamber to movement of a second member from a first position to a second position, the system having a pressure equalization line in communication with the fluid chamber allowing fluid to flow into the chamber when the second member is at its first position and out of the chamber when the second member nears the first position when returning from its second position towards its first position.
