Abstract: A fuel injector for delivering fuel to an internal combustion engine includes a nozzle having a valve needle which is movable with respect to a valve needle seat. The valve needle travels through a range of movement between a closed position and an open position to control fuel delivery through at least one nozzle outlet. The valve needle cooperates with a needle sleeve or a control member which is located in a piston guide. The valve needle is movable relative to the needle sleeve or the control member. The needle sleeve or the control member is movable relative to the piston guide.

Abstract: A valve includes a spring with a spring force, an actuator with an actuator force which can act against the spring force, a pin which can be actuated by the actuator, a sealing element which can be coupled with the pin, and a seal seat such that the valve is closed when the sealing element rests against the seal seat. The pin can be moved in the direction of the sealing element by means of the actuator, and the pin can be moved in the direction away from the sealing element by means of the spring. The sealing element can be moved into an open position independently of the pin, wherein a fluid flow through the valve is released in the open position.

Abstract: To improve the accuracy of an injection amount by a fuel injection valve, the open/close operation of a valve body needs to be performed promptly. This requires a configuration in which, immediately after starting movement of a movable member, fluid force generated at a seat portion of the valve body is not transmitted. It is also required to suppress a cohesion phenomenon between an end surface of an anchor and an end surface of a fixed core and to prevent sticking. To solve this problem, an electromagnetic fuel injection valve has a configuration in which a valve body includes a second valve body configured to abut against an anchor at valve close, a first valve body that abuts against the anchor at valve open. The second valve abuts against a stroke stopper arranged on an inner periphery of a fixed core at a time of valve-open.

Abstract translation: 为了通过燃料喷射阀提高喷射量的精度，需要及时地进行阀体的开闭动作。 这需要这样的结构，其中在可移动部件开始移动之后，在阀体的阀座部分处产生的流体力不被传递。 还需要抑制锚固件的端面和固定芯的端面之间的内聚现象并防止粘着。 为了解决这个问题，电磁燃料喷射阀具有这样一种构造，其中阀体包括构造成在阀关闭时抵靠锚固件的第二阀体，在阀打开时抵靠锚固件的第一阀体。 在阀打开时，第二阀与设置在固定铁芯的内周上的行程挡块抵接。

Abstract: The invention relates to a fuel injector having an electromagnet 2 which contains a magnet core 6 and a coil 7 and which further has an armature 9 that is guided on an armature pin 8. The armature pin 8 is guided in a guide sleeve 11 which projects into the electromagnet 2. The fuel injector further has an injector body 4 with at least one injection opening which is introduced into the injector body 4 and which is controlled by an injector needle 5. The aim of the invention is to provide a fuel injector which is functionally improved with respect to the switching times of the fuel injector and the forces that can be generated in the fuel injector while simultaneously simplifying a guide sleeve for an armature pin. This is achieved in that the guide sleeve 11 is integrated into the magnet core 6 and is connected to the magnet core 6 in a formfitting or bonded manner. For this purpose, the guide sleeve 11 has widened sections 16 at both ends, said widened sections fixing the guide sleeve 11 in the magnet core 6.

Abstract: A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity.
