  • Patent number: 8141843
    Abstract: A valve includes a body, a throttling ball, and a shoe. The body includes an upstream flow passage and a downstream flow passage in fluid communication with an interior cavity of the body. The throttling ball is rotatable within the interior cavity on an axis to adjust the valve from a closed position to an open position and includes a fluid conduit extending through the throttling ball, where the fluid conduit is alignable with the upstream flow passage and the downstream flow passage. The shoe is disposed in the cavity abutting an interior surface of the cavity and includes a fluid passage there through having an inlet being alignable with the flow conduit of the throttling ball and an outlet being alignable with the downstream flow passage of the body. The interior surface of the shoe is disposed adjacent to and tracking an external surface of the throttling ball.

  • Patent number: 8141845
    Abstract: The present invention is directed to a fuel cell supply for a fuel cell having an outer casing, a liner member containing methanol, and a valve component comprising a valve body member and a slidable body member disposed inside the valve body member. The slidable body member is normally biased toward a valve seat surface to seal the valve component and the slidable body member can be moved away from the valve seat surface to open the valve component. The liner member, the valve body member and the slidable body member are made from at least two different materials and wherein at least one of the members compatible with methanol. Hence, each component can be selected from material(s) that is substantially optimal for its function in the fuel supply.

  • Patent number: 8141579
    Abstract: A valve including a valve body having an inlet port and an outlet port, a valve stem, a valve seat, an opening control chamber for the valve stem, which chamber, by being fed with fluid, urges the valve stem to move towards the open position of the valve, a return spring of opposing effect, and a piston suitable for sliding in the body so as to urge contact to be established between the valve stem and the seat. The valve seat is formed on the piston, which piston is provided with a bore in which the valve stem is in its closure movement, the fluid flows out via a constriction from a damping chamber.

  • Patent number: 8141844
    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: 8141849
    Abstract: A valve body and seal assembly comprises a valve body symmetrical about a longitudinal axis and comprising a circumferential seal retention groove and a frusto-conical valve body impact area for contacting a valve seat. An elastomeric seal is cast-in-place in the circumferential seal retention groove. Each seal comprises first and second seal sections in contact via an intra-seal interface, the interface simultaneously extending radially outward and longitudinally. First seal sections may comprise a first polyurethane having a higher modulus than a second polyurethane of which second seal sections may be comprised. First seal sections are cast and partially cured in a mold which is rotating about the longitudinal axis. Second seal sections are cast after the first seal sections are partially cured, resulting in the intra-seal interface shape described above. Cross-linking between first and second seal sections across the intra-seal interface is thus facilitated.

  • Patent number: 8136790
    Abstract: An electromagnetic actuator for a hydraulic directional control valve is provided. The electromagnetic actuator is used for adjusting a hydraulic directional control valve, for example, for the variable adjustment of the control times of an internal combustion engine. The electromagnetic actuator includes a housing (08) with which the electromagnetic actuator is mounted opposite the hydraulic directional control valve. The electromagnetic actuator further includes a coil (01) that is arranged in a coil body (03). The electromagnetic field that can be generated with the coil (01) acts on an armature (09) that is arranged in the electromagnetic actuator so that it can move axially. In order to prevent that the hydraulic medium of the hydraulic directional control valve leaks from reaching the electromagnetic actuator, the actuator includes a seal (13; 24) between the coil body (03) and the housing (08). The coil body has a holder (26, 28) for holding the seal (24).

  • Patent number: 8136789
    Abstract: A valve actuator operates a valve, such as a drain valve of an industrial washing machine. The valve actuator has a permanent magnet DC motor which drives a gear train which rotatably drives an output shaft. The output shaft is engaged with the drain valve and moves the drain valve to open and closed positions as desired. The valve actuator also has a controller which controls operation of the valve actuator. The controller provides power to the motor only when needed to open and close the drain valve. The controller does not provide power to the motor when the drain valve is in the open and closed positions.

  • Patent number: 8128060
    Abstract: A non-sliding solenoid valve has an armature supported by a spring for movement with no sliding contact with other valve surfaces. An inner perimeter of the spring is snapped into position adjacent to an inner perimeter reference surface on the armature. An outer perimeter of the spring engages a reference surface on a shell of the valve, and another reference surface spaced, from the spring reference surface, receives an outer perimeter of a seat for the valve. When the seat is positioned against its reference surface, this urges the inner and outer perimeters of the spring against respective reference surfaces and completes the assembly with assured accuracy.
