Abstract
A valve assembly for an injection valve may include a valve body including a central longitudinal axis, the valve body having a cavity with a fluid inlet portion and a fluid outlet portion, and a chamber, with an electro-magnetic actuator unit arranged in the chamber, and a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in further positions. The valve needle is designed to be actuated by the electro-magnetic actuator unit. A bellows arranged between the valve body and the valve needle is sealingly coupled to the valve body and to the valve needle. The bellows prevents a fluid flow between the cavity and the chamber. An injection valve comprising such a valve assembly is also disclosed.
