Abstract
A unit for controlling valves being actuated by electromagnets for a pressure fluid includes a housing having a housing frame and a lid defining an interior. At least one valve coil and components of the at least one valve coil, such as a wound coil body and a yoke ring, are disposed in the housing. The at least one valve coil is spaced from the housing frame defining interstices therebetween, and the components are mutually spaced apart defining interstices therebetween. A circuit carrier is disposed in the interior of the housing and is electrically connected to each valve coil. The same resilient potting composition fills up the interstices between the components and between each valve coil and the housing frame, without any boundary layers. A method for producing such a unit includes resiliently embedding the components and the at least one valve coil in the housing frame in one operation with the resilient potting composition.
