How does a gas spring work?
Ameritool gas springs are a a self-contained pneumatic device capable of producing very large forces (5 to 1200 pounds) from a compacted piece. A typical gas spring consists of a shaft connected to a piston, which moves within the cylinder. This contains nitrogen at high pressure with a hole in the piston allowing gas pressure to pass through and act equally on both sides of the piston. The shaft passes through a seal at one end of the cylinder and it is the pressure acting on the shaft cross section which provides the spring its force.
