ABSTRACT:
A telescopic fluid ram or thruster utilizing pressurized gas and having an inner and outer piston that slides within a cylindrical bore including a central probe which is tapered and extends into the bore of the inner piston where it will cause the inner piston to move under high pressure while the gas escaping from around the tapered area produces a holding force to hold the outer piston in place until the inner piston is fully extended, at which time the outer piston will extend under a reduced pressure.
