  • Patent number: 8944409
    Abstract: Tunable fluid ends reduce valve-generated vibration to increase fluid-end reliability. Tunable fluid end embodiments comprise a family, each family member comprising a fluid end housing with at least one installed tunable component chosen from: tunable check valve assemblies, tunable valve seats, tunable radial arrays and/or tunable plunger seals. Each tunable component, in turn, contributes to blocking excitation of fluid end resonances, thus reducing the likelihood of fluid end failures associated with fatigue cracking and/or corrosion fatigue. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized. Subsequent damping and/or selective attenuation of vibration likely to excite one or more predetermined (and frequently localized) fluid end resonances represents further optimal use of fluid end vibration-control resources.

  • Patent number: 8567754
    Abstract: Tunable valve assemblies attenuate valve-generated vibration at one or more predetermined assembly resonant frequencies which are typically altered to correspond to specific pump housing resonant frequencies. Each tunable valve assembly comprises a valve body having a peripheral groove spaced radially apart from a central reservoir. An adjustable flange may be coupled to the valve body for imposing a predetermined shear preload by partially constraining a viscoelastic element in the reservoir. One or more valve assembly resonant frequencies are thus predictably altered. Further, the associated valve-generated vibration spectrum is narrowed, and its amplitude is reduced through hysteresis loss of closing impulse energy at each predetermined assembly resonant frequency. Assembly resonant frequencies are additionally or alternatively altered through choice of viscoelastic elements and inclusions (e.g., shear-thickening materials) in the reservoir and/or peripheral groove.

  • Patent number: 8567753
    Abstract: A tunable valve assembly comprises a valve body, an adjustable preload flange centrally coupled to the valve body, and a viscoelastic element; the assembly attenuates valve-generated vibration transmitted to a pump housing. The vibration spectrum is narrowed and its amplitude reduced through hysteresis loss of closing impulse energy. The viscoelastic element comprises a peripheral groove portion coupled to a central reservoir portion via a plurality of fenestration portions. At least a first predetermined assembly resonant frequency is achieved by changing valve assembly compliance (with associated hysteresis loss) through adjustment of annular shear preload applied by the flange to the viscoelastic element reservoir portion. Such preload adjustment effectively maximizes hysteresis loss at the resonant frequency. At least a second predetermined assembly resonant frequency is achieved through choice of a circumferential shear-thickening material within the viscoelastic element groove portion.

  • Patent number: 8550425
    Abstract: An impulse tolerant valve assembly comprises a valve body having a longitudinal axis and a central internal cavity, the cavity enclosing a nonlinear spring-mass damper optionally immersed in a dilatant liquid. The central internal cavity is enclosed by a proximal valve body portion and a distal elastic valve body base plate, the base plate having a peripheral valve seat interface. Impulse tolerance results in part from hysteresis heat loss due to compliance of the elastic valve body base plate, as well as from heat loss associated with operation of the nonlinear spring-mass damper. The combined heat loss is reflected in reduction of closing energy impulse amplitude and damping of induced valve body vibrations. Compliance of the elastic valve body base plate increases closing energy impulse duration and narrows the corresponding induced vibration spectrum. The valve body has at least one guide and at least one peripheral seal-retention groove.

  • Patent number: 8496224
    Abstract: A tunable valve assembly attenuates valve-generated vibration at one or more predetermined assembly resonant frequencies. The assembly comprises a valve body having a peripheral groove spaced radially apart from a central reservoir. An adjustable preload flange is centrally coupled to the valve body for changing assembly compliance and for imposing a shear preload by partially constraining a viscoelastic element in the reservoir. Assembly resonant frequencies are thus predictably altered. Further, the vibration spectrum is narrowed and its amplitude reduced through hysteresis loss of closing impulse energy at each such altered resonant frequency. At least a first predetermined assembly resonant frequency is achieved through adjustment of shear preload, and at least a second predetermined assembly resonant frequency is achieved through choice of a viscoelastic or composite element in the peripheral groove.

  • Patent number: 8464999
    Abstract: A fluid regulating device comprises an actuator with upper and lower housing components. The upper and lower housing components are secured together at mating flanges via a plurality of fasteners. The upper housing component is formed with a vent to contain a relief valve, which exhausts fluid to the atmosphere under overpressure conditions. The upper housing component is constructed such that it does not require a pedestal or fins extending between the vent and the flange, which advantageously provides a completely unobstructed, continuous, ring-shaped flange for receiving and manipulating the fasteners during assembly and/or maintenance of the regulating device.

  • Patent number: 8413682
    Abstract: Fluid valves having an integral safety shut-off are described. An example valve assembly includes a body defining a flow path between an inlet and an outlet and opposing seating surfaces. The example valve assembly includes first valve trim including a first valve stem operatively coupled to a first closure member, the first closure member to engage one of the seating surfaces to control fluid flow between the inlet and the outlet during normal operation. The example valve assembly includes second valve trim including a second valve stem operatively coupled to a second closure member, the second closure member to engage the other one of the seating surfaces during a failure condition to restrict fluid flow between the inlet and the outlet. A surface of the second closure member to define a partial wall of the flow path during normal operation such that a profile of the flow path defined by the body and the second closure member is substantially continuous.

  • Patent number: 8387656
    Abstract: A pressure monitoring device in accordance with the present invention comprises a housing 1 within which are provided an air inlet 2 and an air outlet 3. Connecting the air inlet 2 and the air outlet 3 is an air passage way 4 which includes a pressure take off point 9. The air inlet 2 includes' a threaded bore section 2a into which is screwed a coupling device 7 for coupling with the air outlet of a compressed air supply. The air outlet 3 is also configured to receive a coupling device 8 for coupling with the air inlet of a paint spray gun. A digital pressure gauge 5 is housed in a top surface of the housing 1 as shown in the figures. The gauge samples air pressure at the pressure take off point 9 through conduit 9a. Screw threaded into a bore 11 in the housing is a needle valve 6 which can be adjusted by means of valve adjustment means 10a, 10b to move further towards or away from the pressure take off 9.

  • Patent number: 8365760
    Abstract: A slide valve for blocking a line conveying media includes a housing having a passage opening and a slider plate moveable within the housing at right angles to the passage opening. The slider plate can be displaced from an open position into a closed position blocking the passage opening tightly by a drive mechanism. A lateral seal is disposed in a respective groove in the housing above the passage opening on both sides of the slider plate at right angles to its direction of displacement. The inside and outside of the housing and the slider plate are provided with at least one layer forming a temperature barrier, and the lateral seal includes a high temperature-resistant layer or sealing compound. The risk of a leak into the atmosphere and/or in the passage during a fire or during extinguishing efforts is thus substantially reduced.
