Abstract
An adjustable speed gas spring primarily adapted for use has a part of a door closing mechanism. The gas spring includes a piston assembly which is disposed within an elongated fluid chamber and which upon relative rotation of the shaft with respect to the tubular body, permits the user to adjust the shaft extension velocity. The gas spring is fully functional in any shaft orientation.
