Pressurized gas driven actuator and sealed piston rod used therefor

摘要

A piston rod assembly of a pressurized fluid driven actuator is provided. The piston rod assembly comprises a piston rod (150) having a fluid flow path extending along the inside of the piston rod, and a piston rod (150) fixed to the piston rod (150) at a position along the fluid flow path And a cap (900). Sealing means (910) is disposed between the piston rod (150) and the cap (900) to provide a liquid tight seal between the piston rod (150) and the cap (900).(FIG.
