    摘要： A valve for metering a fluid, which is used in particular as a fuel injector for internal combustion engines, includes an electromagnetic actuator and a valve needle, which is actuatable by the actuator, and is used for actuating a valve closing body, which interacts with a valve seat surface to form a seal seat. An armature of the actuator has a through hole, through which the valve needle extends. The armature is guided on the valve needle movably and with clearance. Furthermore, a stop surface which is fixed in place with respect to the valve needle is provided, on which the armature strikes with its end face in conjunction with an actuation. During an axial alignment of the armature with respect to the valve needle, an angle offset is predefined between the stop surface and the end face of the armature.

    摘要： An injection valve assembly includes a valve body having a central longitudinal axis and a cavity with fluid inlet and outlet portions, a valve needle axially movable in the cavity to control a fluid flow through the fluid outlet portion. The valve needle includes a radially extending retainer element. An electro-magnetic actuator unit including an armature axially movable in the cavity and designed to actuate the valve needle via the retainer element, and a pole piece fixedly coupled to the valve body and including an inner recess, the retainer element being at least partially arranged in the inner recess. The pole piece includes a stop element extending radially into the inner recess of the pole piece. The stop element has a stop surface facing the fluid outlet portion and the retainer element.

    摘要： A common rail fuel injector includes a control valve member unattached to, but trapped between, a push pin and a seat of an injector body. The push pin has a head that includes a contact surface and a crown that includes a stop surface. An air gap surface of an armature is located between a top of the head and the stop surface of the crown when the contact surface of the push pin is in contact with the armature. The stop surface of the crown is located between an air gap plane of a stator assembly and the air gap surface of the armature. The push pin, the armature and the control valve member are movable among a rest configuration, an injection configuration, and an over travel configuration.

    摘要： In one aspect, a fuel injector includes an injector body that defines a fuel inlet, a drain outlet and a nozzle outlet. A direct operated check valve is positioned in the injector body and includes a needle valve member with an opening hydraulic surface exposed to fluid pressure in a nozzle supply passage, and a closing hydraulic surface exposed to fluid pressure in a needle control chamber. The needle valve member is movable between a first position at which the nozzle supply passage is blocked to the nozzle outlet, and a second position at which the nozzle supply passage is open to the nozzle outlet. A needle control valve is positioned in the injector body and includes a control valve member movable between a first position at which the needle control chamber is fluidly connected to the drain outlet, and a second position at which the needle control chamber is fluidly blocked to the drain outlet. A solenoid actuator is positioned in the injector body and includes a stator assembly and an armature assembly coupled to the control valve member. One of the stator assembly and the armature assembly includes a non-magnetic insert that moves into and out of contact with another of the stator assembly and the armature assembly at an energized position and a de-energized position, respectively.

    摘要： The injector comprises a metering servo valve for controlling a rod for opening/closing a nebulizer. The servo valve has a valve body having a control chamber provided with an outlet passage that is opened/closed by an open/close element that is axially movable. The open/close element is separate from an armature of an electromagnet, and is slidable on an axial guide element for closing the outlet passage. The open/close element is held in the closing position by a spring acting through an intermediate body. The armature can be displaced with respect to the axial guide element between a flange of the intermediate body and a projection element of the guide member, for eliminating the rebounds of the open/close element upon closing of the solenoid valve.
