    Abstract: Embodiments of a valve device that reduces noise and vibration that may occur during low flow conditions in fluid couplings (e.g., valves and flow regulators). These embodiments utilize a plug and seat arrangement with geometry to prevent pressure differentials that cause the plug element to open and close in a cyclic pattern. In one embodiment, the valve device includes a seat element with an aperture and a plug element with a boss that extends into the aperture when the plug element contacts the seat element. The boss has an outer surface that forms a gap, which defines an annular area proximate the point of contact between the seat element and the plug element that is sized to reduce Venturi flow effects that cause the cyclic pattern to occur.

    Abstract: A tunable valve assembly reduces valve-generated vibration. One embodiment comprises a valve body and valve seat having substantially collinear longitudinal axes. A rebound characteristic frequency is associated with rebound of the elastic valve body base plate from forceful contact with the valve seat. A central cavity in the valve body encloses a spring-mass damper optionally immersed in a dilatant liquid and having a damper resonant frequency approximating a pump housing resonance. A lateral support assembly adjustably secured to the valve seat has a support resonant frequency designed in conjunction with the rebound characteristic frequency and the damper resonant frequency. Combined hysteresis heat loss associated with the above three vibration frequencies is reflected in lower closing energy impulse amplitude and damping of associated vibrations.

  • Patent number: 8602284
    Abstract: A fastener driving device includes a nose assembly carried by a housing that has a reservoir. The nose assembly has a fastener drive track. At least a portion of the fastener drive track is defined by a movable portion of the nose assembly. A fastener driver is movably mounted in the housing and configured to enter the drive track and drive successive leading fasteners into a workpiece. A head valve is constructed and arranged to be actuated so as to allow the pressurized gas to move the fastener driver through an operating cycle. An actuator is constructed and arranged to actuate the head valve. The actuator includes a trigger valve constructed and arranged to allow passage of the pressurized gas from the reservoir to a chamber above the head valve, and a contact valve operatively connected to the movable portion of the nose assembly.

  • 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.
