摘要： Three-way valves having reduced leakage and fuel injectors using the same. Three-way spool poppet valves are disclosed having a spool with a poppet valve thereon cooperating with a seat on the valve housing to provide a substantially leak free valve closing in one direction characteristic of a poppet valve while preserving the advantages of a spool valve. Three-way ball valves are also disclosed having substantially leak free valves closing in both directions, but further including reduced short circuit losses due to direct flow from a high pressure source to a low pressure vent during transition of the ball from one position to the opposite position. Fuel injectors with direct needle control using the three-way valves of the present invention are also disclosed.

摘要： A linear control valve is disclosed regulating the flow of fluid to hydraulically activated devices, preferably a fuel injector and an engine compression release brake. The valve includes a valve member that is moveable between a first position in which the fuel injector is, at least partially, activated, a second position in which neither the fuel injector nor the engine compression release brake is activated, and a third position in which the engine compression release brake is activated. An electrical actuator providing two permanent magnets and two oppositely wound solenoid coils moves the valve member between its three positions. The polarity of the permanent magnets are oriented such that when the solenoids are energized, one solenoid coil pulls the valve member while the other solenoid coil pushes the valve member in the same direction.

摘要： A solenoid end cap assembly having a flat mating surface. The flat mating surface is a single planar mating surface and is designed to mate with a substantially flat mating surface of a valve control body. The solenoid, housed within the solenoid end cap, does not protrude past the flat surface and may form part of the substantially flat mating surface of the solenoid end cap. The flat mating surfaces of the valve control body and the solenoid end cap assembly eliminates the need for ring dowels in the assembly between the solenoid and the valve control body. This reduces manufacturing costs and assembly time. The flat mating surfaces also provide a uniform mounting surface for the solenoid from injector to injector. This increases performance characteristics, as well as increases thermal conductivity and magnetic conductivity characteristics.

摘要： A booster unit is provided in an injector of a fuel injection system. The booster unit includes a booster piston accommodated in a pressure chamber, and a discharge valve capable of discharging fuel in a backpressure chamber. A needle valve drive unit includes a pressure-receiving piston and an open/close valve. A return passage is connected to a discharge side of the open/close valve. A fuel discharge passage in communication with the discharge valve is combined with the return passage in a confluence portion. A check valve is provided between the confluence portion and the open/close valve. A check valve permits the fuel discharged to the return passage from a pressurization chamber to be directed to the confluence portion, and prevents the fuel discharged to the fuel discharge passage from the backpressure chamber from being directed the open/close valve.

摘要： A fuel injection system for an internal combustion engine including a fuel injector which can be subjected to fuel at high pressure and is actuatable via a metering valve device by which the pressure in a pressure booster control chamber is controllable such that the pressure in a pressure booster pressure chamber, defined by a pressure booster piston, that can be filled with fuel from the high-pressure fuel source via a filling path in which a check valve is disposed and that is in communication with an injection valve member pressure chamber, is increased by the pressure booster piston such that an injection valve member opens for injecting fuel, whereupon fuel is positively displaced out of a damping chamber via a damping path, in which a damping throttle is disposed. To assure stable injection performance, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from the damping chamber via the damping throttle in an injection event reaches the filling path of the pressure booster pressure chamber via the damping path.

摘要： The invention relates to a fuel injector for injecting fuel into a combustion chamber of an internal combustion engine. The fuel injector is in communication with a high-pressure reservoir for fuel and includes a pressure booster. The fuel injector is actuatable via a control valve and has an injection valve member, which is urged in the closing direction by at least one spring element, and associated with the injection valve member is a damping element that is movable independently of it. This damping element defines a damper chamber, and the injection valve member has a first needle part and a second needle part. Associated with the second needle part is a control chamber that can be connected to the system pressure side or the maximum pressure side.

摘要： A fuel injector in injection systems for internal combustion engines having a valve body containing a control chamber that can be pressure-relieved and can be acted on with fuel via an inlet throttle and can be pressure-relieved via an outlet throttle. A first actuator can actuate a closing element. The valve body is connected to a holding body that has a nozzle body connected to it, which encompasses an injection valve element. In order to relieve the pressure in the control chamber, an additional, second outlet throttle is provided, whose closing element can be actuated either by an additional actuator or as a function of the power supply to a double-switching actuator.
