Abstract
A proportional pressure regulating valve has a spring-loaded valve piston () guided in and actuated by an actuating magnet () within a valve housing (). Opposite valve piston sides are exposed to tank pressure. The valve piston () has a regulation surface () connectable to working port (A) for a regulation pressure (PR). A ring-shaped chamber () in the valve housing () opens into the working port (A). At the transition between the ring-shaped chamber () and the working port (A), the regulation surface () is active. When the actuating magnet () is deenergized, a maximum regulation pressure (PR) is generated.
