Pressurized Actuator

摘要

A linear actuator contains a housing having a first end and a second end. A hollow piston is positioned within the housing to slidably engage with an inner wall of the housing. A sealed gas chamber is formed within the hollow piston and contains stored gas for driving the piston upon activation of the actuator.

主权项

1. A linear actuator containing:
a housing having a first end and a second end; a hollow piston rod contained within said housing, said piston rod having a third end and a fourth end, the third end proximate to the first end and the fourth end proximate to the second end; a sealed gas chamber formed within the hollow piston rod; a stored gas contained within the sealed gas chamber; and an initiator fixed at the first end and proximate to the third end of the piston, for releasing the stored gas upon activation of the actuator to thereby drive the piston rod.
