Abrégé

An energy generating system for transforming energy of fluid flow into electric energy, the system, at least in operation, comprising: a flow-changing member having a peripheral rim and mounted in a fluid path having a path surface, so as to be at least partially surrounded by said path surface, said flow-changing member being displaceable between a first position, in which at least a portion of the rim is spaced from a corresponding portion of the path surface to a first extent and a second position, in which said portion of the rim is spaced from said portion of the fluid path surface to a second extent greater than said first extent, so that increase of total volumetric flow rate of said fluid above a predetermined threshold to an increased volumetric flow rate is configured to induce displacement of said flow-changing member from said first position toward said second position, thereby causing the volumetric flow rate of said fluid at said spacing to be above said increased volumetric flow rate; and a turbine mounted in fluid communication with said fluid path at a location other than said spacing, whereby said displacement causes the volumetric flow rate of said fluid at said turbine to be below said increased volumetric flow rate.

A system for use with a fluid-containing body having a body wall with an opening and defining a body interior, and for use with a device to be inserted and extracted by said system via said opening into the fluid-containing body, said system having a central axis and comprising: a proximal portion configured for being attached to the body wall when mounting the system in said opening, and having a first chamber configured for receiving said device therein; a sealable interface having a first side facing said first chamber and a second side in a direction opposite said first chamber and defining a distal area configured for receiving said device from said first chamber; said sealable interface, when unsealed, being configured to allow passage therethrough of the device along said central axis between the first chamber and the distal area; a pressure regulating mechanism configured for regulating pressure within said first chamber between pressure at an upper exterior of the proximal portion and pressure at the distal area; and a second chamber encompassing at least a part of the distal area and configured for receiving the device therein; said sealable interface, when unsealed, being configured to allow passage therethrough of the device along said central axis between the first and the second chambers.

Abrégé

An apparatus for positioning thereof in a liquid flow path, comprising: a housing configured to be received in the flow path and having a liquid inlet and a liquid outlet defining a flow direction therebetween; a current generator including a shaft supported by the housing and having a rotor mounted thereon and having a plurality of vanes, the shaft extending in the housing along the flow direction allowing rotation of the rotor with the vanes by liquid passing through the generator, and a stator associated with the rotor for producing electrical signals corresponding to the rotation of the rotor; and, electrical wiring for electrically connecting the current generator to a power receiver for transferring the electrical signals thereto.
