摘要： In various embodiments a fluid control device suitable for high pressure analytical instruments includes a housing having an interior surface with an end wall. The interior surface defines a chamber. A valve assembly disposed in the chamber controls the flow of fluid through the chamber. An end cap is disposed in the housing opposite the end wall to enclose the chamber. The end wall and end cap each have an opening to pass a fluid to the chamber or to remove a fluid from the chamber. The housing and end cap each has an abutment surface to receive the other abutment surface. At least one of the abutment surfaces has a plastic seal coating. A means of compression, such as a compression housing and compression sleeve, is included to engage the end cap to deform the plastic seal coating between the abutment surfaces and thereby seal the chamber.

摘要： Embodiments of the present invention are directed to devices and methods for propelling fluids that feature at least one first pump assembly having a primary pump, an accumulator pump, drive means, valve means and control means. The valve means moves between the first position and the second position as the accumulator pump and primary pump alternate between a loading movement and a pump movement. The control means is in signal communication with the accumulator pump, the primary pump and the valve means. The control means issues signal command to the accumulator pump to assume the loading movement and the pump movement and the primary pump to assume the loading movement and pump movement in coordination with the movement of the valve means such that fluids are propelled from the first outlet.

Either or both of the rotor and the stator have a seal-surface coating formed by depositing an at least partially amorphous interlayer on a substrate and depositing a surface layer, including diamond-like carbon, on the interlayer. The surface layer requires no mechanical polishing.

摘要： In general, the invention features a spring assembly for a gauge with a hollow metal tube that changes in volume in response to differential pressures applied across the walls. The tube has a neck connected to a fitting of the gauge, a body connected at one end to the neck with its other end sealed, and at least a portion of the walls of the body being flattened and cold worked to a reduced thickness to thereby increase their yield point to a spring temper. The body is coiled into a spiral or helix. The coiled tube is heat treated to increase its elasticity. The interior of the neck is in pressure communication with the fitting, and the interior of the body is in pressure communication through its unsealed end with the interior of the neck, whereby a change in the pressure applied to the fitting is communicated along the interior of the body changing the differential pressure across the walls of the body to cause a corresponding change in the volume.

摘要： A rotary shear valve assembly for liquid chromatography applications comprises a rotor assembly having a rotor and a drive shaft with a head portion. The rotor has a substantially planar surface with one or more rotor grooves and a pair of holes. The head portion has two pins. The pins are disposed substantially diametrically opposite of each other on a line through a center of the head portion. Each pin mates with one of the holes in the rotor. The rotor assembly can further comprise means for urging the rotor surface against the stator surface such that each rotor groove aligns with and provides a fluidic channel between two of the stator openings.

摘要： A shear valve for use in a high performance liquid chromatography system. The shear valve includes a first valve member having a plurality of first fluid-conveying features, and a second valve member having one or more second fluid-conveying features. The second valve member is movable, relative to the first valve member, between a plurality of discrete positions such that, in each of the discrete positions, at least one of the one or more second fluid-conveying features overlaps with multiple ones of the first fluid conveying features to provide for fluid communication therebetween. At least one of the first and second valve members is at least partially coated with a protective coating that includes an adhesion interlayer and a diamond-like carbon (DLC) layer. The DLC layer is deposited on the adhesion interlayer via filtered cathodic vacuum arc (FCVA) deposition.
