    Abstract: A valve assembly including a housing having a flow channel and an annular surface surrounding the flow channel, a slide plate movable to a closed position, and a seal ring positioned between the annular surface and the slide plate. The seal ring includes a first and second sides, a first surface extending between the first and the second sides and facing towards the annular surface of the housing, and a second surface axially spaced from the first surface and extending between the first and the second sides and facing towards the slide plate. The second surface includes a continuous annular sealing portion for contacting the slide plate when the seal ring is biased against the slide plate so that a fluid-tight seal can be formed between the continuous annular sealing portion and the slide plate, and at least one passageway positioned between the annular sealing portion and the second side.

    Abstract: A valve assembly including a housing having an opening defined by a valve seat, a valve body movable within the housing between a completely opened position disengaged from the valve seat and a completely closed position engaging the valve seat, and a sleeve movable longitudinally along, and rotatably about, a longitudinal axis. The sleeve is connected to the valve body so that the valve body can rotate and move longitudinally with the sleeve. One of the housing and the sleeve includes a cam surface, and the other of the housing and the sleeve includes a cam follower received by the cam surface. A rotatable shaft is in threaded engagement with the sleeve so that rotation of the shaft causes at least one of rotation and longitudinal movement of the sleeve against the cam follower.

    Abstract: A valve assembly including a housing having a flow channel, a slide plate movable between a closed position and an opened position, and a seal ring surrounding the flow channel and engaging the slide plate in the closed position and disengaging the slide plate in the opened position. The seal ring has a plurality of bores aligned, respectively, with holes formed in an adjacent surface of the housing. Each bore includes an undercut defining a lip. A plurality of fasteners are arranged in the holes of the annular surface of the housing and extend into the corresponding bores of the seal ring. Side walls of the fasteners include slots, which catch on the lips of the bores of the seal ring when the fasteners are inserted into the bores of the seal ring, and the seal ring is rotated.

    Abstract: A pressure transducer assembly includes a first body, a diaphragm, and an electrode. The diaphragm is mounted between the first and second bodies. The first body and the diaphragm form a first chamber. The second body and the diaphragm form a second chamber. The electrode is disposed in the first chamber. A portion of the diaphragm flexes in a first direction in response to pressure in the first chamber being greater than pressure in the second chamber. A portion of the diaphragm flexes in a second direction, opposite the first direction, in response to pressure in the second chamber being greater than pressure in the first chamber. A capacitance between the electrode and the diaphragm is representative of a difference between the pressures in the first and second chambers. In some embodiments, the electrode is suspended from a hub and spoke mounting. In some embodiments the electrode is entirely metallic. In other embodiments, the electrode includes a ceramic disk with a conductive film formed on the disk and the disk is coupled to the housing with a ceramic rod. In some embodiments, the transducer also has a low thermal coefficient of expansion member connected to the housing for reducing warping in response to temperature changes. In additional embodiments, the disk includes a groove that reduces the effects of temperature variations on a ceramic electrode.
