  • Patent number: 4005728
    Abstract: A faucet valve to control the volume flow of hot or cold water, such as in a sink fixture, includes a housing having a hollow chamber, a cap removably attached to said housing and defining a passage offset from the axis of the chamber, and a stem rotatably disposed within the housing and having an inlet passage offset from the axis of rotation of the stem. A resilient grommet seal is disposed in the passage in the cap and is in sliding sealing engagement with the stem. The cap can be removed from the housing to replace the grommet, or to reverse the direction of rotation of the stem member between the open and closed positions, whereby the faucet valve can be interchangeably used in the hot or cold water lines of a sink fixture.

  • Patent number: 3990468
    Abstract: A universal logic body block includes a number of identical cavities having accompanying passageways of identical number and pattern. Each single cavity forms the basic housing for installation of various components to perform logic functions AND, OR, NOT and TIM. A primary universal insert fitted within the above-described cavities of the universal logic body block in combination with various other valve elements will provide an AND, or NOT logic function. A universal secondary seat may be fitted within a cavity in one manner in combination with other components, to provide the logic functions AND, OR and NOT. Additional specialized inserts are provided for insertion into a cavity of the universal logic body block in combination with various valve elements to provide the TIM logic function or the OR function. Various logic circuits can be formed in one block by means of connections between separate logic devices.

  • Patent number: 3990477
    Abstract: A flow control valve includes a valve body defining a main bore and a cross-drilled bore communicating therewith. A valve spool is reciprocable within the main bore and includes first and second lands connected by a reduced diameter connecting portion. The connecting portion has fixed relative thereto and thereabout an annular rib, positioned between the two lands. The rib acts as a guide to direct fluid substantially perpendicular to the axis of reciprocal motion of the spool when the spool is positioned to allow fluid flow between the main and cross-drilled bores, to minimize fluid flow forces tending to hold the spool in an open position.

  • Patent number: 3986526
    Abstract: A train of fluid pulses representative of a process variable is processed by digital fluidic circuits and is then converted into an analog fluid pressure signal which is compared to an analog command signal, the difference between the two compared signals being caused to appear in the form of a displacement. This displacement is amplified by means of a fluid servo system, the amplified output of which is utilized for directly driving a control element for a process.

  • Patent number: 3983899
    Abstract: A check valve having a body with an inlet and an outlet which are coaxially aligned and a valve element including a section of a sphere which is spring loaded urging the valve element towards and sealing against the inlet. The valve element is supported on a stem which is coaxially movable in the valve body. The body has a cavity of a cross-sectional area greater than the valve element by an amount at least as great as the area of the inlet whereby the valve avoids restricting the flow of fluid through the body. Locking means are provided for locking the valve element in the closed position.

  • Patent number: 3983895
    Abstract: Pipeline capsules, pigs, or other solid objects bypass a pipeline pump station via a bypass system that avoids cycling of the primary fluid flow. The fluid is removed from the main pipeline through perforations in the pipeline wall, transported through the pump and reinjected into the main pipeline downstream from the fluid removal point. Two valves are located in the main pipeline between the fluid removal point and the fluid reinjection point. The first valve is opened in response to the detection of the incoming solid object, allowing it to pass through the valve. The first valve is then closed and the second valve opened to allow the solid object to pass through the second valve and re-enter the main fluid stream.

  • Patent number: 3977433
    Abstract: A valve structure comprises an elongated housing having a passage extending therethrough, and a control member mounted in the passage for rectilinear movement with respect to the housing. The housing has a plurality of spaced valve ports extending therethrough in communication with the housing passage. A plurality of sealing means are non-uniformly spaced along the length of the control member for movement therewith, with each of the sealing means sealingly engaging adjacent wall surfaces of the housing passage. The sealing means in one position of the control member define a given flow circuit among the valve ports, and in another position of the control member its sealing means define a different flow circuit among the valve ports.

  • Patent number: 3974852
    Abstract: The valve is adapted to close against the force of a bias spring in response to a substantial increase in the pressure drop through restricted by-pass passages in the valve when a hose is ruptured on the outlet side of the valve. The restriction of the by-pass passages is adjustable by rotation of an internal adjustment ring to thereby determine the flow rate at which the valve is actuated.

  • Patent number: 3973753
    Abstract: Gate valve having a closure member mounted on a swinging arm pivotally mounted for movement transversely of the axis of the valve openings. A wedge member carried by the arm drives the closure member in a direction parallel to the axis of the openings when moved longitudinally of the arm. An actuator pivots a cam which bears against the wedge member to swing the arm to a predetermined position in which the closure member is aligned with the openings and thereafter to move the cam to drive the closure member axially and seal one of the openings. Resilient members urge the closure member toward its retracted position and prevent the wedge member from moving forward until the arm reaches the predetermined position.

  • Patent number: 3972364
    Abstract: A pressure surge relief system including a valve which is opened to relieve the pipeline when line pressure overcomes a pilot chamber pressure. A pilot load duct with a variable orifice device therein connects the chamber to the pipeline. In the event of a surge, the orifice retards pressure build-up in the chamber so that it will be overcome by higher pressure in the pipeline. Pressure responsive means makes the orifice device more restrictive as pressure increases to produce a pressure lag at the control chamber even at lower velocities.
