摘要： An electromagnetic control valve is provided. The control valve includes a housing defining a bore and a fluid passageway having a seat. A valve element is slidably disposed in the bore and is moveable between a first position where a flow of fluid passes by the seat and a second position where a flow of fluid relative to the seat is blocked. A solenoid having an armature is operatively connected with the valve element. The solenoid is operable to move the valve element from the first position to the second position. A biasing assembly is operatively engaged with the valve element and is adapted to move the valve element from the second position towards the first position. The biasing assembly exerts a first force on the valve element during a first predetermined travel distance from the second position and a second force on the valve element during a second predetermined travel distance. The first force is greater than the second force.

摘要： A bipolar bandgap reference circuit employing three resistors of selected nominal resistance values and a method of trimming the values of two of the resistors to cancel the slope and curvature of output voltage due to thermal drift. One of the resistors provides a positive temperature coefficient to counter the temperature dependency of bipolar base-emitter characteristics; this resistor is not trimmed. The other two resistors are thin-film, low TC devices and are "trimmed" (i.e., adjusted) sequentially, to match calculated values intended to minimize the first and second derivatives of the bandgap cell output, as a function of temperature.

摘要： An apparatus includes a plurality of display elements arranged in an array and a control matrix coupled to the plurality of display elements to communicate data and drive voltages to the display elements. For each display element, the control matrix includes an actuation circuit coupling a voltage source to the display element. The control matrix is configured to apply an actuation voltage to an actuator of the display element throughout an actuation stroke of the actuator and to initiate the actuation of the actuator after a pre-charging signal that initiated the application of the actuation voltage to the actuator has been deactivated.

摘要： A solenoid actuated device such as a fuel injector includes an actuator body having a plurality of body pieces, and a single-pole solenoid actuator assembly positioned at least partially within the actuator body. The single-pole solenoid actuator assembly includes a one-piece compound armature housing having a load carrying component clamped between the first body piece and the second body piece, and a flux carrying component. The load carrying component includes a high structural strength and a low flux permeability, and the flux carrying component includes a low structural strength and a high flux permeability. A method of making a solenoid actuated device includes placing an armature at a sliding radial air gap with a flux carrying component of a one-piece compound armature housing, and establishing a structural load path by placing a load carrying component of the compound armature housing between a first actuator body piece and a second actuator body piece. A method of operating a single-pole solenoid actuator device includes supporting a flux carrying component of a one-piece compound armature housing with a load carrying component of the compound armature housing, channeling magnetic flux across a sliding air gap between a flux carrying component and the armature, and channeling a clamping load between a first actuator body piece and a second actuator body piece through the load carrying component of the compound armature housing.

摘要： A solenoid actuator includes a hard guide piece and a soft flux piece. The hard guide piece has a stop surface ground to create a final air gap distance between the soft flux piece and a stator assembly when the stop surface on the guide piece is in contact with the stator assembly. The final air gap is set by grinding the stop surface on the guide piece so that the distance between the stop surface on the guide piece and a top surface on the soft flux piece along an axis of the guide bore is equal to the final air gap. The step of grinding the armature assembly may be done after attaching the guide piece and the flux piece together. In an exemplary embodiment, the step of grinding the stop surface and associated guide surface(s) are performed in a single chucking.

摘要： A fuel injector for a common rail fuel system includes a common rail inlet port fluidly connected to a high pressure common rail, and a cooling inlet fluidly connected to an output from a lower pressure fuel transfer pump. The cooling fluid circulates internally through the fuel injector to cool a single pole solenoid via both internal and peripheral cooling passages. In order to accommodate a small spatial envelope while providing superior performance, a thin insulating layer may separate the solenoid coil winding from an inner pole piece, and small flux gap clearances may permit a flux carrying portion of the injector body to be a portion of the single pole solenoid assembly.

摘要： A system for preloading piezoelectric actuators includes a fixture, a preloading mechanism configured to apply a mechanical force to a piezoelectric element supported by the fixture, and a sensor configured to sense an electrical property induced by the mechanical force in an electrical circuit having the piezoelectric element therein. A control device is coupled with the sensor and configured to generate a signal based on the sensed electrical property. A method of setting or testing preload includes applying a mechanical force to a piezoelectric element, and correlating an electrical property induced by the mechanical force with a magnitude of the mechanical force. Closed loop control allows preload to be set highly accurately.
