Abstract

An electromagnetic actuating unit for a hydraulic valve with a housing and a closure element. The housing at least partially delimits the electromagnetic actuating unit in relation to the surroundings. The closure element is arranged within an introductory opening of the housing. A sealing-means receptacle is formed on a boundary surface between the housing and the closure element. Furthermore, at least one first channel leads into the sealing-means receptacle and is open towards the surroundings of the actuating unit. A sealing element, which is arranged in the sealing-means receptacle is placed into the sealing-means receptacle via the first channel.
