An electrically operated valve assembly including a valve member maintained on a seat by a tensioned wire or filament which is heated to permit the valve member to move off of its seat. A piston and cylinder assembly including a conduit therein for permitting pressurized fluid to actuate the piston when an electrically operated valve of the type described above is actuated. A self-contained system including a reservoir, compressible liquid in the reservoir, a squib for pressurizing the compressible liquid, a piston and cylinder, a conduit between the reservoir and the cylinder, and a valve of the above-described type in the conduit for selectively admitting pressurized compressed liquid to the cylinder. A piston and cylinder system including a plurality of the above-described valve assemblies and associated conduits for selectively admitting hydraulic liquid to opposite sides of the piston to move it in opposite directions.
