摘要： A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

摘要： A rack and pinion gear train actuator for a pintle valve. A motor shaft has a pinion gear that engages a large reduction gear having an integral hub gear. The hub gear is a planet gear for a ring gear segment that pivots on a shaft and includes a pinion gear segment that engages a linear rack. The rack is attached to a valve pintle shaft, causing the valve to be opened and closed in response to rotation of the motor shaft. The pintle shaft, return spring, rack, and gears are all assemblable by slip fit. The actuator has a high actuation force, a fast response time, and compact design by virtue of a rack and internal gearing. The stroke of the rack may be changed for use with pintle valves having differing strokes by varying the angle through which the motor operates.

摘要： A motorized cam actuator for linear actuation of an apparatus. An actuating motor shaft is fitted with a bushing having first and second opposed flats and a threaded portion at an outer end thereof. With the motor mounted to a pedestal, the bushing is rotated on the shaft to a predetermined angular position such that assembly stack up is cancelled. The bushing is then fixed to the shaft by welding. A cam with a central opening is mounted onto the bushing, the opening having flats for mating with the flats on the bushing. The cam is mounted onto the bushing and is secured thereto by a nut. This arrangement eliminates any relative motion between the bushing and the motor shaft and prevents stress on the weld joint from reaching failure levels.

摘要： An anti-coking bushing assembly for sealing a pintle shaft of an EGR control valve, comprising a bushing carrier disposed in the valve body and supportive of close-fitting pintle shaft bushing liners formed of a polyimide such as Vespel. The bushing carrier and bushing liners are installed into a carbon shield extending into the exhaust flow space within the valve. Within the carbon shield, between the gas flow space and the bushing carrier, is a ring seal on the pintle shaft and a gas expansion chamber to cool exhaust gas escaping along the pintle shaft, allowing contaminants in the exhaust gas to precipitate in the gas expansion chamber. The carbon shield, ring seal, bushing carrier, and bushing liners are conveniently pre-assembled as an anti-coking bushing assembly for subsequent installation into a valve body during final valve assembly.

摘要： A remote control lever module comprising a support including a bearing and a lever including a shaft pivotably supported by the bearing for oscillation about the shaft axis between a nonactuating position and actuating positions. The lever further includes an actuating arm extending from the shaft at an angle thereto for moving the shaft between the nonactuating position and the actuating positions and a return spring acting on the lever when the shaft is in the actuating positions to urge the shaft to the nonactuating position. Magnets are fixed on the shaft and movable therewith to provide a movable magnetic field of varying strength in an effective zone adjacent one side of the shaft. A magnetic field sensor is fixed to the support adjacent to the shaft in the effective zone of the magnetic field and operative to sense the variation in strength of the magnetic field at various positions of the shaft and to form a readable output signal proportional to the variations for indicating the angular position of the shaft. The lever module may also have a lever force switch engageable by the shaft to close the switch when the actuating arm urges the shaft into the actuating positions.

摘要： An electro-hydraulic valve assembly includes a center pole mounting an electric solenoid assembly and slidably received in a valve boss. The solenoid assembly controls the fluid pressure in a chamber defined in the center pole. Fluid in the chamber is biased against a deflectable disc which controls fluid flow through the valve assembly. Control of electric current to the solenoid assembly controls fluid pressure in the chamber and, thus, fluid flow through the valve assembly. When utilized with a damper and a controller, the present valve assembly provides continuously variable damping in real time.

摘要： A dual-poppet valve comprising a valve body having spaced-apart coaxial valve seats and being arranged such that first and second poppets both open into the primary chamber. A first pintle shaft engages the first poppet, and a second pintle shaft engages the second poppet. A motorized actuator having a gear transmission includes a pinion gear. The pintle shafts include opposing gear racks, and the pinion gear engages both racks. Thus, rotation of the pinion gear in a first direction causes both poppets to be lifted from their seats simultaneously, in opposite directions; and counter-rotation engages each poppet with its respective seat. In closing, one poppet engages its seat slightly before the other poppet engages the other seat. The first pintle slides through the first poppet until the second poppet is fully seated by the actuator. The force of the spring fully engages the first poppet with the first seat.

摘要： A bearing module for a pintle valve including a pintle bearing, bearing spring, and two-part housing. The bearing has an axial face for sealing against an inner axial surface of the housing. The bearing diameter is less than the diameter of the housing, permitting the bearing to float radially. The housing fits into a port in the valve body and also extends over an axial surface of the body, thus forming a seal against the wall of the port and the surface of the body. The bearing spring, preferably a wave washer, is compressed within the housing as the two housing parts are assembled to form the module. In a currently preferred embodiment, the housing further comprises a coking shield extending along the surface of the pintle shaft within the valve port to reduce the tendency for coking gases to enter the bearing module.

摘要： A pressure regulating valve assembly includes a valve body mounting an electric solenoid assembly. The solenoid assembly controls the fluid pressure in a chamber defined in the valve body. Fluid in the chamber is biased against a deflectable disc which controls fluid flow through the valve assembly. Control of electric current to the solenoid assembly controls fluid pressure in the chamber and, thus, fluid flow through the valve assembly. When utilized with a damper and a controller, the present valve assembly provides continuously variable damping in real time.
