  • Patent number: 8251348
    Abstract: The present invention relates to valve plugs for reducing erosion of the valve plug head and/or seat. More specifically, this invention comprises a valve plug incorporating a choke transfer trim that reduces the time of exposure of the plug head and/or seat to high velocity and high pressure drop at the interface of the plug head and seat when the valve is in the closed position. The choke transfer trim transfers the flow control area of the valve away from the plug head/seat interface to a location downstream, thereby reducing erosion at the interface between the valve plug head and/or seat that is typically used for fluid throttling and shut off.

  • Patent number: 8246005
    Abstract: In an electromagnetic fuel injection valve in which: a suction tubular part projecting toward an inside of a nonmagnetic cylindrical body is provided to a front end portion of a stationary core; and a front end of the suction tubular part and a rear end of a movable core are opposed to each other in the inside of the nonmagnetic cylindrical body, an annular gap allowing influx of pressure fluid used for a check of liquid-tightness between the nonmagnetic cylindrical body and the stationary core is provided between an outer peripheral surface of the suction tubular part and an inner peripheral surface of the nonmagnetic cylindrical body. Accordingly, it enables a quick and efficient judgment to be made on a check on liquid-tightness of a welded part by applying fluid pressure to the inside of the valve housing after the valve housing of the electromagnetic fuel injection valve is produced.

  • Patent number: 8240635
    Abstract: Improving the accuracy of the flow rate of a valve in a fluidic delivery device in which a desired flow rate may be achieved by varying the duty cycle of the valve. The flow rate of fluid delivery from the valve over its lifetime is stabilized by minimizing the voltage OPENING time of the valve to account for valve and piezoelectric actuator drift. Also, the valve OPENING time of one or more fluidic parameters that impact on the flow rate delivery by the valve and differ among fluidic delivery devices is compensated to optimize the flow rate accuracy.

  • Patent number: 8240634
    Abstract: A high-pressure valve assembly includes a flange defining an axis. Projecting into the flange is a valve body which is sealed against the flange by a static ring seal. Provided on one side of the valve body is a spring-loaded closure member which is supported for movement in a direction of the axis to form a suction valve, and on another side of the valve body in opposition to the one side is a spring-loaded tappet which is supported for movement in the direction of the axis to form a pressure valve. A channel connects the suction valve with the pressure valve and has one end porting into a pressure chamber of the valve body adjacent to the pressure valve. The pressure chamber extends in axial direction of the tappet and is sized to extend substantially above a bottom edge of the ring seal.

  • Patent number: 8235355
    Abstract: A slide valve, in particular for blocking a line conveying media, is provided with a multi-part housing (2) having a passage opening (3). Disposed in this housing (2) are two slider plates (4, 5), parallel to one another, moveable at right angles to the passage opening (3), and which can be moved from an open position into a closed position tightly blocking the passage opening (3) by means of a common drive mechanism (10). Means are provided for connecting the two slider plates (4, 5) to one another and to the drive mechanism (10), and which in the closed position allow a pre-determined relative movement of the slider plates (4, 5) in relation to one another in their direction of movement. Thus, even with tolerance deviations with regard to the slider plates and/or their counter-surfaces, a long-lasting blocking function of both slider plates is guaranteed.

  • Patent number: 8220494
    Abstract: Using basic physical arguments, a design and method for the fabrication of microfluidic valves using multilayer soft lithography is presented. Embodiments of valves in accordance with the present invention feature elastomer membrane portions of substantially constant thickness, allowing the membranes to experience similar resistance to an applied pressure across their entire width. Such on-off valves fabricated with upwardly- or downwardly-deflectable membranes can have extremely low actuation pressures, and can be used to implement active functions such as pumps and mixers in integrated microfluidic chips. Valve performance was characterized by measuring both the actuation pressure and flow resistance over a wide range of design parameters, and comparing them to both finite element simulations and alternative valve geometries.
