Patent number: 9370858Abstract: A high pressure tool assembly includes a tool and a hand control valve connected to the tool. A hydraulic manifold is fluidly connected to the hand control valve. An intensifier is fluidly connected to the hydraulic manifold and to the tool. The intensifier increases the pressure of a first operating fluid supplied to the tool. A first fluid circuit is formed between the hand control valve, the hydraulic manifold and the intensifier. The first fluid circuit operates at a first pressure. A second fluid circuit is formed between the intensifier and the tool and operates at a second pressure. The second pressure is larger than the first pressure. The second fluid circuit is isolated from the first fluid circuit.Type: GrantFiled: June 24, 2013Date of Patent: June 21, 2016Assignee: Hubbell IncorporatedInventors: John D. Lefavour, Thomas R. Faucher, William L. Benedict, Henry A. Maxwell, James Del Bonis
