Gas spring with braking means
摘要:
A pressurized gas spring, which exerts an expulsion force on the piston rod entailing a maximum extension velocity of the piston rod, includes braking means effective at a velocity of motion due to external forces above the maximum extension velocity for limiting the velocity of motion to a desired measure.
