    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 relatively inexpensive robust attachment strategy that insures good perpendicularity between a valve member and an armature utilizes an intervening nut between the armature and valve member. A valve member is received in a guide bore of a valve body. A nut is threaded onto one end of a valve member. The armature is press fit onto a orientation neutral interface of the nut, and a fixture is utilized to set near perfect perpendicularity between an air gap plane of the armature and a centerline of the valve member. The armature is then welded to the valve member. The weld may be accomplished via laser welding while the valve assembly is firmly held in an appropriate position within the fixture. The valve assembly may be then incorporated into a fuel injector stack of components in a conventional manner.

    摘要: A fuel injector includes an injector body having an internal surface and an external surface. A tappet assembly includes a non-guided tappet and a plunger assembly, and is mounted on the injector body. The tappet assembly is movable with respect to the injector body a displacement distance between an advanced position and an extended position. A portion of the plunger assembly is slidably guided along the internal surface of the injector body, while the non-guided tappet is free of contact with both the internal surface and the external surface of the injector body in the advanced and extended positions. The tappet assembly may be prevented from moving beyond the extended position using a snap ring positioned within a retention opening of the fuel injector body.

    摘要: A fuel injector for an internal combustion engine having a crankshaft is disclosed. The fuel injector has plunger to displace fuel and an electronically controlled spill valve. The fuel injector also has a nozzle member having at least one orifice and a valve needle disposed within the nozzle member, and movable against a spring bias to selectively inject pressurized fuel through the at least one orifice. The fuel injector also has an electronically controlled check valve. The valve needle is automatically moved to inject pressurized fuel when the pressure of the fuel within the fuel injector reaches a predetermined valve opening pressure determined by a spring bias. Valve elements of the electronically controlled spill and check valves are both in a flow blocking position before the pressure of the fuel within the fuel injector reaches the predetermined valve opening pressure. Injection terminates when the valve element of the electronically controlled check valve is moved to a flow-passing position.

The display apparatus also includes a control matrix including, for each light modulator in the array, a single actuation voltage interconnect. The actuation voltage interconnect is configured to apply a first drive voltage to the first actuator of the light modulator and apply a second drive voltage to the second actuator of the light modulator. In addition, the actuation voltage interconnect is configured to control application of a data voltage to a latch circuit to control the application of the first and second drive voltages to the first and second actuators.
