Hydraulic damper with compressed gas extend assist

A door positioning system including:

• a door housing defining a doorway;
• a door that is movably coupled to the door housing such that the door is movable from a closed position where the door blocks the doorway to an open position where a user is able to move entirely through the doorway;
• a door actuation system including:
• an actuator having an interior chamber, a base end, and a movable end that is actuatable relative to the base end based on a pressure within the interior chamber, wherein the actuator is coupled to the door;
• a fluid line fluidly connected to the interior chamber;
• a single-use pressurized tank fluidly connectable to the interior chamber through the fluid line;
• and
• an activation valve operably coupled to the actuator and to the single-use pressurized tank;
• and
• wherein when the activation valve is in a first position the single-use pressurized tank is not fluidly connected to the interior chamber;
• and
• wherein when the activation valve shifts to a second position the actuator is shifted into an actuation state where the single-use pressurized tank is fluidly connected to the interior chamber to pressurize the interior chamber, thereby actuating the movable end of the actuator relative to the base end and moving the door between the closed position and the open position.
