  • Patent number: 9370858
    Abstract: 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.

  • Patent number: 9205541
    Abstract: A high pressure tool assembly includes a hand control valve mechanically connectable to a tool. An intensifier is fluidly connected to the hand control valve and to the tool. The intensifier increases pressure of an operating fluid to be supplied to the tool. A first fluid circuit conveying the first operating fluid is formed between the intensifier and the tool. A second fluid circuit conveying a second operating fluid is formed between the hand control valve and the intensifier. The first fluid circuit operates at a first pressure. The second fluid circuit operates at a second pressure. The first pressure is higher than the second pressure. The first fluid circuit is isolated from the second fluid circuit.
