  • Patent number: 11204121
    Abstract: A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

  • Patent number: 8701780
    Abstract: A down-hole jet pumping apparatus and method for removing accumulated water in a small diameter well bore are described. Chosen fluids are pumped under high pressure from a surface pump through a 3-way valve into a tube disposed in a well bore. The jet pumping apparatus includes a down-hole accumulator connected to an eductor. The high-pressure fluid is stored in the accumulator and may be released to the surface reservoir by the control valve through the tube along with the fluid to be pumped drawn into the eductor. When the accumulator is exhausted, the control valve again directs high-pressure fluid from the surface pump to the accumulator until a chosen pressure is achieved in the accumulator. The fluid pressure in the accumulator is maintained using a gas-charged metal bellows. Hydraulically driven jet boosters are described for increasing the fluid pressure along the tube in deep wells.

  • Patent number: 8678776
    Abstract: The invention relates to a vacuum generating device (1) and to a method suitable for the operation thereof. An ejector device (27) is connected with an inlet (29) thereof to an air supply conduit (32) that can be selectively closed or opened by an electronic control unit (14) in order to selectively turn off or turn on the ejector device (27). When the ejector device (27) is turned on, a vacuum is generated in a suction channel (35). The ejector device (27) is operated such that the vacuum fluctuates between an upper switching value and a lower switching value. By comparison to a reference time value, the operating period of the ejector device (27) is determined in order to generate a diagnosis signal that allows a conclusion of the leak that is present.

  • Publication number: 20140050595
    Abstract: A quick-release vacuum pump which is mainly applied to a vacuum transport system. The vacuum pump has a mechanism in which part of compressed air supplied for generating a vacuum state is stored firstly in a chamber, and then the vacuum state within the chamber is released when transportation is completed. When the vacuum state is released, a check valve is moved by the pressure of air that flows backward. The range of movement of the check valve is adjusted by a control means. An air filter is disposed at the lower end of the check valve. The release of the vacuum state is quick and controllable. Also, the filter is naturally filtered and cleaned.

  • Publication number: 20140030118
    Abstract: This present invention is a method and apparatus for drag reduction for a nautical vessel. The nautical vessel produces air bubbles and interposes the air bubbles between the exterior of the hull of a nautical vessel and the body of water that the vessel is moving through. Rather than utilizing an air compressor or other external energy source, the compressed air is generated from the movement of the vessel and is released where needed in order to reduce drag on the vessel.

  • Patent number: 8622140
    Abstract: A method to produce formation fluid from an oil or gas well. The methods employs a jet pump and a spoolable multi-string tubing system. The jet pump is adapted to produce formation fluid, which may be produced in combination with power fluid. The multi-string tubing system consists of two or more tubing conduits, allowing surface pump equipment to deliver power fluid to the jet pump down a supply tubing string, while return fluid is returned up a return tubing string. Other downhole functions can be provided with the inclusion of additional features on the jet pump and additional conduits or conductors in the multi-string tubing system. Preferred embodiments provide additional functionality by inclusion of a jetting sub, sensing elements, or a back-pressure valve to the jet pump, and auxiliary tubing strings or communication members to the spoolable multi-string tubing system.
