Abstract:
An intensifier comprising:a body including first, second, third, and fourth manifolds, said first and second manifolds defining an intensifier chamber that is filled with a gaseous fluid, said second and third manifolds defining a reservoir chamber, and said third and fourth manifolds defining a work chamber that is filled with substantially all water; an intensifier piston disposed within said intensifier chamber and having an intensifier rod secured thereto that extends through said second manifold into said reservoir chamber and is movable through said third manifold into said work chamber; a reservoir piston disposed within said reservoir chamber and having a central opening formed therethrough through which said intensifier rod extends, said reservoir piston separating said reservoir chamber to define a water reservoir chamber that is filled with substantially all water and an air reservoir chamber that is filled with a gaseous fluid in selective communication with a source of a gaseous fluid; a work piston disposed within said work chamber and having a work rod secured thereto that extends through said fourth manifold from said body; and a plurality of ports formed in said body for permitting the flow of said gaseous fluid and said water to and from said intensifier chamber, said reservoir chamber, and said work chamber to selectively move said work rod relative to said body.
