Abstract: A microfluidic valve assembly includes a structure defining a microfluidic fluid path and an actuator that can be moved between different positions controlling flow through the channel. In one embodiment, the actuator can be threaded into at least a portion of the structure, and can be moved rotationally between a first position, causing relatively greater constriction of a microfluidic fluid path, and a second position causing relatively lesser constriction of the fluid path. Actuating the actuator, e.g., by rotation, can deform material between the valve and the fluid path, thereby constricting at least a portion of the underlying fluid path and regulating the flow of a fluid in the fluid path. In another aspect, the invention provides a reservoir into which fluid can be placed and from which fluid can be introduced into a microfluidic system. In one embodiment, the reservoir is expandable and thereby able to store fluid under pressure for delivery to a microfluidic system.

Abstract: Certain types of riser tensioner arrangements include a high-pressure accumulator; a pusher-type hydraulic cylinder; a first flow path coupling the high- pressure accumulator with a first volume of the cylinder to enable a first high- pressure fluid to flow therebetween; and a second flow path coupling the high- pressure accumulator with a second volume of the cylinder to enable a second high- pressure fluid to flow therebetween. The piston includes a seat and a hollow extension that defines part of the second volume of the cylinder.

Abstract: An expandable accumulator and reservoir assembly includes a housing defining an interior chamber configured to contain a working fluid therein. An expandable accumulator is positioned at least partially within the housing. The expandable accumulator includes at least one flexible member configured to be at least partially immersed in the working fluid contained within the interior chamber. A rigid support member is positioned in the interior chamber and outside of the expandable accumulator. The rigid support member has at least one aperture to allow passage of the working fluid. An additional flexible member is positioned outside the rigid support member and has perimeter portions sealed to the outside of the rigid support member. The additional flexible member defines a flexible boundary between a primary reservoir inside the additional flexible member and a separate secondary reservoir outside the additional flexible member.

Abstract: A fluid system comprises a pressure vessel with a baffle oriented at a skew angle. The baffle divides the vessel into first and second volumes. A first port is provided to introduce a pressurizing fluid into the first volume, and a second port is provided to circulate a working fluid within the second volume. A purge aperture is provided to purge the pressurizing fluid from the second volume across the baffle into the first volume, and a flow aperture is provided to transfer the working fluid through the baffle between the first and second volumes.
