ABSTRACT:
A proportionally adjustable pressure limiting valve wherein a valve cone may be actuated via an armature of a proportional solenoid. The valve cone is cardanically supported in the armature. Additional guidance of the valve cone is effected through the intermediary of a housing-side guide, wherein the play between valve cone and housing-side guide is designed to be less than the play between valve cone and armature.
