    摘要： An electrically controlled fluid control valve comprises an electrical position controller governed by a signal proportional to the position of a movable element of the valve to regulate current to a shape memory alloy (SMA) valve actuator to position the movable element to a desired position. The control valve may also include a temperature controller governed by a signal provided by a temperature-sensing element in proximity to the valve actuator to activate a cooling device for reducing the surrounding temperature. A digital selector switch may be used for generating a digital code of a selected heating rate which may govern the electrical controller to regulate current to the SMA drive element. The electrical controller may also be governed by both position measurement and a temperature signals to regulate current to the SMA valve actuator and to control the cooling device to position the movable element to a desired position.

    摘要： A fluid control valve having a shaped memory alloy (SMA) driven actuator is disclosed. The SMA driven actuator includes a first frame section coupled to a valve body and fixed in relation thereto, a second frame section coupled to a movable element of the valve body and movable in relation to the valve body, and a multiplicity of SMA wire sections coupling the first and second frame sections for moving the movable element from a biased first position to a second position when heated. An electrical controller controls the heating of the SMA wire sections by regulating current therethrough, preferably using pulse width modulation techniques. The electrical controller may be governed by a position measurement signal proportional to the position of the movable element to regulate current to the SMA drive element to position the movable element to a desired position. The position measuring signal may be provided from a position measuring element integral to the valve actuator. The valve actuator may also include a temperature controller governed by an electrical temperature signal provided by a temperature-sensing device in proximity to the SMA drive element to activate a cooling device for reducing the temperature surrounding the SMA drive element when activated. A digital selector switch may be used for generating a digital code of a selected heating rate which may govern the electrical controller to regulate current to the SMA drive element. The electrical controller may also be governed by both a position measurement and a temperature signal to regulate current to the SMA drive element and to control the cooling device to position the movable element to a desired position. The actuator may include at least one bobbin that is wound with a multiplicity of wire windings. A conductive material may be applied to the surface of grooved sections of the bobbin onto which the SMA wire windings are wound. Alternatively, the SMA wire may be coated with a conductive material and then wound about the bobbin and thereafter, the conductive material may be removed from the surface of the SMA wire not in contact with the bobbin.

    摘要： The present application relates to an arrangement for selectively providing a plurality of output forces, such as for example, a higher and a lower output force or a predetermined, time dependent output force. In one embodiment, a first piston assembly is moveable between a first and a second position and a second piston assembly moveable between a third and a fourth position. When the first piston assembly is in the first position, the second piston assembly is selectively movable between the third position and the fourth position. When the first piston assembly moves the second position, it moves the second piston assembly to the fourth position.

    摘要： A flow control device having a control member for forming a seal with another part of the flow control device. The control member having a base material and a portion or surface that is a softer or more deformable than the base material or the portion of the control device that the control member forms a seal with. The differences in hardness and/or the ability of the control member portion to deform, aids in forming the seal.

    摘要： A valve includes a valve body, a valve element to selectively control flow through the valve, and a seal member and seat member together providing a fluid-tight seal between a valve cavity and a fluid passage in the valve body. A live-loaded biasing member is adapted to apply a live-loaded sealing force to the seat member to bias the seat member toward sealing engagement with the valve element. When the pressure in the fluid passage exceeds the pressure in the valve cavity, an unbalanced passage pressure load biases the seat member toward sealing engagement with the valve element. When the pressure in the valve cavity exceeds the pressure in the fluid passage, an unbalanced cavity pressure load biases the seat member toward sealing engagement with the valve element. The live-loaded sealing force is in parallel with each of the unbalanced passage pressure load and the unbalanced cavity pressure load.
