Abstract
Various implementations include a linear actuator that provides controllable depressurization of the actuator and is tunable to the specifications set by the vehicle manufacturer. The linear actuator includes a housing and a piston and piston rod that are slidably disposed within a channel extending through the housing. The piston rod defines a vent path that includes an axial cavity adjacent the proximal end of the piston rod and radial channel extending from the axial cavity to an outer peripheral surface of the piston rod. Pressurized gas entering the housing causes the piston to move axially through the housing, and a portion of the gas vents through the cavity and radial channel to the channel of the housing and then to the environment. This venting allows the actuator to be returned to its initial or stored position within a time frame and without exceeding the force set by the manufacturer.
