- a pressure chamber;
- a cylindrical body having a top end and a bottom end and a longitudinal axis extending through its center from the top end to the bottom end;
- a top piston, having a top end and a bottom end corresponding with the top end and bottom end of the cylindrical body, providing a slidable seal within the pressure chamber;
- a bottom piston, having a top end and a bottom end corresponding with the top end and bottom end of the cylindrical body, providing a slidable seal within the pressure chamber;
