An outer tube installed to a lower portion of the inner tube having a high pressure chamber and a gas chamber between the shell and the outer tube. A diaphragm divides the high pressure chamber from the gas chamber. A body valve is installed to a lower end of the inner tube to control flow of fluid between the low pressure chamber and the high pressure chamber, and a pump rod is provided having a hollow portion and one end installed to the body valve and another end inserted into the hollow portion of the piston rod.
