2.1. Existing valve control devices are set up in housings that feature also the complete yoke in addition to the valve spools.2.2. In order to reduce the assembly effort required as well as the play of the valve domes on the inside of the spool, yoke arrangements are mounted externally on the housing.2.3. Such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.
