  • Patent number: 9683669
    Abstract: An unclamp delay valve for delaying release of hydraulic pressure in a hydraulic holding device. The unclamp delay valve may have a check valve allowing fluid to flow between an inlet port and an outlet port when held open by a piston translatable within a piston chamber. The check valve blocks fluid from flowing between the outlet port and the inlet port when released due to hydraulic fluid filling the piston chamber and translating the piston away from the check valve. To reopen the check valve, hydraulic pressure is released via the inlet port and slowly drains from a small orifice fluidly coupling the piston chamber and the inlet port, causing the piston to return to again open the check valve. A delay is thus created by the time it takes for the piston chamber to drain, thus opening the check valve to release hydraulic pressure therethrough.

  • Patent number: 8474415
    Abstract: A valve assembly for a fluid system is provided. The valve assembly includes a damping component to reduce undesired pressure fluctuations within the system. The valve assembly includes a valve guide member and a valve member at least partially situated around the valve guide member. The valve member may be slidable relative to the valve guide member. The valve member is configured to move between a first valve member position that substantially permits fluid flow from the fluid system through the valve assembly, and a second valve member position that substantially prevents fluid flow from the fluid system through the valve assembly. A metering hole is formed on the valve member and adapted to dampen the motion of the valve member from the first valve member position to the second valve member position.

  • Patent number: 8474786
    Abstract: Valve stem and valve plug apparatus for use with fluid regulators are described herein. An example fluid regulator includes a flow control member having a body that includes a longitudinal bore between a first end and a second end and a valve stem is disposed in the bore of the flow control member. A connector slidably couples the valve stem and the flow control member such that the connector moves away from the flow control member to relieve the flow control member of a loading force imparted by a loading element of the fluid regulator when the flow control member sealingly engages a valve seat of the fluid regulator.

  • Publication number: 20130042930
    Abstract: A hydraulic pilot control unit includes at least one pressure control valve that can be controlled by means of an actuating device. The pressure control valve includes a control piston connected to a stem by means of a neck. The stem has a resilient operative connection to the actuating device. The neck is fastened to the stem. Thus, the mass of the control piston, which tends to oscillate, is reduced compared to the prior art.

  • Publication number: 20130008512
    Abstract: A pulsation control device coupling a reciprocating pump with either suction or discharge piping and having a generally spherical or cylindrical interior chamber includes a curved baffle with a pressure drop device (e.g., a choke) there through separating the interior chamber into two volumes and forcing fluid flow through the pressure drop device. The effective fluid passage provided by the pressure drop device is smaller than the fluid passage for one or both of the inlet to and/or the outlet from the interior chamber. Fluid entering the pulsation control device reacts with fluid contained within the volume thereof on both sides of the baffle. The baffle attenuates pressure pulses within fluid passing through the interior chamber in response to operation of the reciprocating pump, and in particular improves acoustic pulsation energy reduction.

  • Patent number: 8333178
    Abstract: A control valve, for use in controlling fuel pressure within a control chamber, comprises a control valve member, first flow restriction and second flow restriction. The control valve member is movable between a first position, and a second position. The first flow restriction is arranged to maintain a first pressure upstream of the first flow restriction when the control valve member is in transition between the first position and the second position. The second flow restriction is positioned downstream of the first flow restriction and is arranged to maintain a second pressure upstream of the second flow restriction. The second flow restriction is dimensioned and located relative to the first flow restriction such that in transition between the first and second positions the net force exerted on the control valve member by the first pressure balances the net force exerted on the control valve member by the second pressure.

  • Patent number: 8307869
    Abstract: The present invention is a wheel assembly having a rim with a valve aperture extending therethrough that is designed to receive a valve having a simplified a construction that can be seated directly within a tire wheel assembly to minimize the number and type of components necessary for the valve. The valve includes a main body that is positionable in a sealed and recessed or embedded configuration within the aperture in the wheel rim in communication with the interior of the tire and with a pressurized air source that is used to inflate or deflate the tire. The main body encloses a valve mechanism that includes a components situated within the main body in a manner that enables the parts to be easily removed, cleaned and/or replaced if necessary without having to remove the entire valve assembly from the wheel.

    Abstract: A bi-directional pressurized system with devices for and configured to mitigate issues associated with leak and creep phenomena at various stages throughout the system, including valves and controls to distribute a leaked amount of fluid prior to delivery to a pressure-sensitive destination and a pressure relief valve to bring an initial pressure within an acceptable range for distribution to reach a target pressure is disclosed. A startup method for mitigating leakage of the system during a rest phase, including selectively reducing the initial pressure upstream of a pressure-sensitive destination, is disclosed.

  • Patent number: 8205636
    Abstract: In a pressure compensation type flow rate control valve, overshoot of a flow rate when an upstream pressure is abruptly increased is suppressed. A first variable orifice 11 is provided on the side of an inflow opening and a second variable orifice 15 is provided on the side of an outflow opening. As the spool 3 is displaced from its initial position by a pressure of fluid entering when the upstream fluid pressure is increased, the opening of the first variable orifice 11 is gradually reduced, and the opening of the second variable orifice 15 is gradually increased. Since the second variable orifice 15 on the side of the outflow opening is previously reduced, even if the upstream pressure is abruptly increased, fluid more than a predetermined amount does not flow out toward the downstream.

  • Patent number: 8162068
    Abstract: A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.
