Locking / Blockable Gas Struts
Blockable gas springs work with a pin in front. While the pin pushed inside the valve system opens and begins action through the valve hole. Gas and oil inside of the tube moves to other side as the tube is divided into two section with the piston at the rod end. The piston moves in or out because of the pressure changes due to gas movement.
