Needle device

摘要

A Needle device for a valve group (2) comprises a needle body, a spring (12) and a transferring element (13). The spring (12) is arranged concentric to the needle body. The transferring element (13) surrounds the needle body and has a clearance to the needle body in radial direction. Further, the transferring element (13) forms a first rest for the spring (12) at a first side of the transferring element (13). The transferring element (13) and a step of the needle body at a second side of the transferring element (13) facing away from the first side of the transferring element (13) are coupled by a sphere/cone coupling.
