  • Needleless injectors
    Patent number: 6620135
    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).
