摘要： A valve assembly for an injection valve has a valve body with a central longitudinal axis and a cavity with a fluid inlet portion and a fluid outlet portion, a valve needle axially movable in the cavity, the needle preventing a fluid flow in a closing position and releasing the fluid flow via a main fluid line in further positions, a member being fixedly associated to the needle and having a surface facing the outlet portion, a first chamber embodied in the cavity, a second chamber being part of the main line, and a one-way-valve which is hydraulically arranged between the first and second chamber to prevent a fluid flow through a first fluid path in a closing position of the one-way-valve and to release a fluid flow through the first fluid path between the first and second chamber in further positions of the one-way-valve.

摘要： An injection valve for injecting fluid has a housing with an injection valve cavity. The injection valve has a needle being axially moveable within the cavity. The needle has a needle body with a valve needle cavity and a separation element being fixedly arranged within the needle cavity and being adopted to divide the valve needle cavity into a first and second fluid volume. The separation element has at least one fluid passage with a predetermined passage opening to hydraulically connect the first fluid volume with the second fluid volume. The valve needle has a sealing element being arranged to predetermine the first fluid volume and preventing a fluid injection in a closing position and permitting the fluid injection in further positions. In addition, the valve needle has at least one spring element being preloaded and acting on the sealing element towards a maximum axial expansion of the valve needle.

摘要： A fuel injector (10) has a housing (12) with a central longitudinal axis (L) having a fluid inlet portion (18) being adapted to be coupled to a fuel rail at a first axial end area (20). The housing (12) has a recess (24) and enables a fluid flow through a fluid outlet portion (26) at a second axial end area (28) facing away from the first axial end area (20). The fluid inlet portion (18) communicates with the fluid outlet portion (26) via the recess (24). Furthermore, the fuel injector (10) has a safety component (30), which is arranged at the central longitudinal axis (L) within the recess (24) and adapted to reduce and arranged for reducing a velocity regarding the central longitudinal axis (L) at the fluid inlet portion (18) of the fluid flowing from the recess (24) through the fluid inlet portion (18).
