  • Patent number: 9867935
    Abstract: The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane (1), a middle plate (2) with pillars and through holes and a bottom plate (3) with fluidic ports, micro channels and through holes (8,9,12). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane.

  • 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.

    Abstract: An apparatus for controlling flow in a fluid flow path can include a chamber containing an expandable material, the expandable material being configured to expand out of the chamber into a portion of the fluid flow path so as to at least partially block the fluid flow path. The apparatus also can include at least one structure providing flow communication between the chamber and the fluid flow path. The at least one structure can be configured to pass the expandable material from the chamber to the portion of the fluid flow path during expansion so as to control a rate at which the expandable material expands into the portion of the fluid flow path.

  • Patent number: 8893745
    Abstract: A pressure relief valve 1 having small dimensions and generating a high flow rate comprises an annular channel 15 between the pressure medium inlet 7 and the pressure medium outlet 8, the channel acting on a sealing cone 17 made of a special plastic material at the upper end of the closing unit 17 in case of pressure peaks such that the same is lifted out of the sealing seat 12 against the force of the valve spring 6. An embodiment is also possible in which the corresponding sealing rings 76, 80 must be passed over. The inner bore 9 of the pressure relief valve 1 has a stepped wall 21, so that a differential pressure relieving the valve spring 6 is generated.

  • Publication number: 20140174551
    Abstract: A variable gas pressure regulator comprises a throttling valve regulating the fluid flow between a high-pressure fluid inlet and a regulated space fluidly connected to a fluid outlet, a high-pressure solenoid commanded to control fluid flow between the fluid inlet and a control space and a low-pressure solenoid commanded to control fluid flow between the control space and the regulated space. The regulator achieves a variable pressure at the regulator outlet by commanding the two solenoids to control the pressure in the control space relative to the regulated space. The regulator further comprises a lock-off valve which is controlled by the action of the low-pressure solenoid and of the high-pressure solenoid based on the relative pressure difference between the control space and the regulated space. The lock-off valve seals the passage between the fluid inlet and the regulated space.

  • Publication number: 20140166111
    Abstract: A sliding sleeve opens with a deployed ball. The sleeve has a seat disposed in the housing, and the seat has segments biased outward from one another with a C-ring or other biasing element. Initially, the seat has an expanded state in the sliding sleeve so that the seats segments expand outward against the housing's bore. When an appropriately sized ball is deployed downhole, the ball engages the expanded seat. Fluid pressure applied against the seated ball moves the seat into the inner sleeve's bore. As this occurs, the seat contracts, which increases the engagement area of the seat with the ball. Eventually, the seat reaches the shoulder in the inner sleeve so that pressure applied against the seated ball now moves the inner sleeve in the housing to open the sliding sleeve's flow port.

  • Patent number: 8689895
    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.

  • Publication number: 20130312702
    Abstract: A passive hydraulically actuated non-electric shutdown pressure relief valve relieves pressure in the high pressure volume of a low static leak common rail fuel system after shutdown. When the common rail fuel system is in operation, a transfer pump provides medium pressure to hold the shutdown pressure relief valve closed. At shutdown, the residual medium pressure downstream from the transfer pump decays back to tank, and the residual high pressure trapped in the common rail and fuel injectors pushes open the shutdown pressure relief valve to release the high pressure after back to tank.

    Abstract: A gas expansion module for use with semiconductor wafer loadlocks and other regulated-pressure components of semiconductor processing tools is provided. The gas expansion module may be barometrically isolated from the loadlock or other component and pumped down to a vacuum condition while the loadlock is performing operations at a higher pressure, such as ambient atmospheric conditions. After an initial pump-down of the loadlock is performed, the gas expansion module may be fluidly joined to the loadlock volume and the gases within each allowed to reach equilibrium. A further pump-down of the combined volume may be used to bring the loadlock pressure to a desired vacuum condition.
