Title: Power conversion system for bi-directional conversion between hydraulic energy and electrical energy
Inventor: BESING WOLFGANG
IPC: H02J4/00
Filed: 1997-10-27
Abstract: A bi-directional power conversion system interconnects hydraulic and electrical power systems on-board a vehicle such as an aircraft, whereby the power conversion system can selectively convert available electrical power to needed hydraulic power or vice versa.  The power conversion system includes a hydraulic machine connected to the hydraulic system of the vehicle, an electrical machine connected to the electrical system of the vehicle through a power converter and control unit, a rotational drive shaft mechanically interconnecting the hydraulic machine and the electrical machine, and a priority and safety control unit that controls the operation of the system.   In a first operating mode,  for example in the event of a failure of a primary electrical generator, the hydraulic machine operates as a hydraulic motor driven by available hydraulic power from the hydraulic system to drive the electrical machine which operates as an electrical generator to provide electrical power into the electrical system. In a second operating mode, for example in the  event  of  a  failure  of  a  primary  hydraulic  pump,  the electrical machine operates  as an electric motor driven by electric power from the electrical system to drive the hydraulic machine operating as a hydraulic pump to provide hydraulic power into the hydraulic system.  A hydraulic valve arrangement and an electrical switch arrangement, as well as pressure and speed regulators are controlled by the control unit, and the system operation is monitored by sensors connected to the control unit, to activate the appropriate operating mode.

Abstract: L'objet de l'invention est l'obtention d'une cartouche (1) qui soit économique à produire et également à remplir, qui ne comporte qu'une petite quantité de matière plastique et qui, lorsqu'elle est jetée, est très peu polluante. En outre, ladite cartouche devrait se prêter au plus grand nombre d'utilisations possibles, être vidée au maximum de sa substance résiduelle et garantir un grand volume de transport. A cet effet, on obtient, selon l'invention, une cartouche (1) pour substance coulante pourvue d'une enveloppe (2) en matière souple délimitant un volume. Ladite cartouche comporte, à une extrémité, un élément d'expression en forme de piston (4) et, à une autre extrémité, un élément de sortie (3). Dans la région de la sortie, se trouve une ouverture de distribution dont le diamètre, compte tenu des forces qui peuvent être appliquées sur l'élément d'expression, de la viscosité de la substance coulante et de la souplesse de l'enveloppe, garantit, dans le volume délimité par l'enveloppe, une pression interne qui peut agir à l'encontre d'un pliage du matériau de l'enveloppe à l'intérieur du volume.
