Abstract
An electromagnetically actuatable valve which serves as a fuel injection valve for fuel injection systems in internal combustion engines. The valve includes a valve housing as well as a magnetic coil with poles serving as the core, with which an armature cooperates, which is connected to a valve element the sealing element of which cooperates with a valve seat in a valve seat body. The valve element protrudes without contact through a throttle bore in the valve seat body with a throttling element and is held in a sealing manner on the valve seat by the armature when the magnetic coil is excited. When the magnetic coil is not excited, the valve element is moved by the pressure forces of the fluid in the opening direction of the valve and is centered by the fluid flow.
