Abstract

The invention relates to an electrohydraulic valve that can be produced essentially in cartridge form and can be used in an oscillating motor camshaft adjusting device. The aim of the invention is to maintain wear and friction in said valve as low as possible and to keep the areas outside a non-magnetic sleeve (7) free from hydraulic fluid. To this end, a pole core insert (40) is used in order to create a design that provides a sleeve (7) which is continuous up to a seal (51).
