    摘要： A fuel injector for use with an internal combustion engine. The fuel injector comprises a valve group subassembly and a coil group subassembly. The valve group subassembly includes a tube assembly having a longitudinal axis that extends between a first end and a second end; a seat that is secured at the second end of the tube assembly and that defines an opening; an armature assembly that is disposed within the tube assembly; a member that biases the armature assembly toward the seat; an adjusting tube that is disposed in the tube assembly and that engages the member for adjusting a biasing force of the member; a filter that is located at the first end of the tube assembly and that has an integral retaining portion; an O-ring that circumscribes the first end of the tube assembly and that is maintained by the retaining portion of the filter; and a first attachment portion. The coil group subassembly includes a solenoid coil that is operable to displace the armature assembly with respect to the seat; and a second attachment portion that is fixedly connected to the first attachment portion.

    摘要： A fuel injector having a fuel inlet, a fuel outlet, and a fuel passageway extending along an axis between the fuel inlet and the fuel outlet. The fuel injector includes a body having an inlet portion, an outlet portion, and a neck portion disposed between the inlet portion and the outlet portion. An adjusting tube is disposed within the neck portion of the body. A spring is disposed within the neck portion of the body, the spring having an upstream end proximate to the adjusting tube and a downstream end opposite the upstream end. A filter and an O-ring retainer assembly are disposed proximate the upstream end. An armature having a lower portion is disposed within the neck portion of the body and displaceable along the axis relative to the body. The downstream end of the spring is disposed proximate to the armature, the spring applying a biasing force to the armature. A valve seal is substantially rigidly connected to the lower portion of the armature. The fuel injector includes a modular valve group subassembly that is connected to a modular coil group subassembly.

    摘要： A medical instrument for cutting soft tissue during an interventional radiology procedure includes a hypodermic needle and a stylet at least partially located within the needle bore. The portion of the stylet located within the needle bore and the needle collectively form at least one fluid passageway. The stylet is movable relative to the hypodermic needle along the needle axis. The stylet is adjustable between a retracted configuration and a protracted configuration. The stylet head is located within the needle bore when the medical instrument is in the retracted configuration. The stylet head is located external to the needle bore when the medical instrument is in the protracted configuration. The fluid passageway enables fluid to flow from the proximal needle end to the distal needle end when the stylet is in the retracted configuration and in the protracted configuration.
