Title: Remote actuated valve implant

Abstract

Valve implant systems positionable within a flow passage, the systems having an inlet, an outlet, and a remotely activatable valve between the inlet and outlet, with the valves being operable to provide intermittent occlusion of the flow path. A remote field is applied to provide thermal or magnetic activation of the valves.

  • Valve implant systems positionable within a flow passage, the systems having an inlet, an outlet, and a remotely activatable valve between the inlet and outlet, with the valves being operable to provide intermittent occlusion of the flow path. A remote field is applied to provide thermal or magnetic activation of the valves.
  • This patent describes a liquid level actuated sleeve value for use in a well tubing in a well casing comprising: a body having connections at each end for connection in a well tubing. The body has a first port in communication between the bore and the outside of the body, and a movable seal energizer sleeve telescopically engaging the body, the sleeve having a second port generally aligned with the first port, a movable sleeve piston telescopically engaging the seal energizer sleeve. The piston includes a third port for opening and closing the first and second ports. The sleeve pistonmore » being exposed on a first side to fluid pressure outside of the body acting in a direction to move the sleeve piston to a closed port position, a pressurized gas chamber in the body in communication with the sleeve piston on a second side and acting in a direction to move the sleeve piston to an open port position, first seal means between the seal energizer sleeve and the sleeve piston, and between the seal energizer sleeve and the body, second seal means between the body and the sleeve piston and engagable by the seal energizer sleeve, and coacting shoulders on the sleeve piston and the seal energizer sleeve for moving the seal energizer sleeve and compressing the second seal means when the sleeve piston moves to the close position.« less
  • The present invention relates to a breeder reactor blanket fuel assembly coolant system valve which increases coolant flow to the blanket fuel assembly to minimize long-term temperature increases caused by fission of fissile fuel created from fertile fuel through operation of the breeder reactor. The valve has a valve first part (such as a valve rod with piston) and a valve second part (such as a valve tube surrounding the valve rod, with the valve tube having side slots surrounding the piston). Both valve parts have known nuclear radiation swelling characteristics. The valve's first part is positioned to receive nuclearmore » radiation from the nuclear reactor's fuel region. The valve's second part is positioned so that its nuclear radiation induced swelling is different from that of the valve's first part. The valve's second part also is positioned so that the valve's first and second parts create a valve orifice which changes in size due to the different nuclear radiation caused swelling of the valve's first part compared to the valve's second part. The valve may be used in a nuclear reactor's core coolant system.« less
  • This patent describes well control apparatus including a valve device with an upper and lower marginal end connected to an elongated tubing means and positioned downhole in a borehole for conducting fluid flow from a lower part of the borehole to the surface of the ground, a packer device associated with the valve device which divides the borehole into an upper and a lower annulus, means placing the upper marginal end of the valve device in communication with the upper borehole annulus and the lower marginal end of the valve device is in communication with the lower borehole annulus. Itmore » comprises: an outer annular housing, an annular mandrel slidably received within the housing; a power chamber formed between the mandrel and the housing, a power piston attached to the mandrel and slidably received with the power chamber; means for effecting annulus pressure within the upper variable chamber; latch means by which the mandrel is latched into a plurality of different vertically spaced latch positions as the mandrel is moved respective to the housing, pressure responsive means by which the latch means is released when the upper annulus pressure is increased to a first magnitude of pressure.« less
