    Abstract: A pressurised gas powered actuator comprising a piston (3) operating in a cylinder (1). The stroke of the piston (3) may be reduced by uncovering one or more holes (14, 20) in the cylinder wall to permit the escape of the pressurised gas at a predetermined position along the swept wall of the cylinder. Alternatively, the piston (401) may be connected to a rod (402) which has a gas vent (406) formed therein, the position of the rod (402) with respect to the piston (401) being variable to adjust the stroke of the piston (401).

    Abstract: A method is provided for filling needleless injector capsules with liquid drug, which eliminates or reduces trapped air bubbles in the drug. A two-stage vacuum method is disclosed which enables the capsule to be evacuated rapidly to very low pressure prior to filling. The method is also suitable for filling other small containers with liquids.
