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.
