Abstract (en)
[origin: WO2013174624A1] The invention relates to a valve device for a hydraulic circuit, comprising an actuator unit (10) having an electromagnetic circuit (14), a valve unit (12) having a first opening (56), a second opening (58) used as an outlet, a first valve closing body (62), which is connected to the armature (22) and is loaded by means of a spring element (40) in the direction of a first valve seat (60) arranged between the first opening (56) and the second opening (58), a third opening (66), which is formed at the end of the valve unit (12) opposite the actuator unit (10), and a second valve closing body (70), which is loaded by hydraulic pressure in the direction of a second valve seat (68) formed between the first opening (56) and the third opening (66) and which can be lifted from the second valve seat (68) by means of the first valve closing body (62), is known. In order to ensure actuation by the spring force, and to avoid adhesive forces due to cohesion, a cylindrical stop element (42) having a passage opening (44) extending in the extension direction is arranged in the passage hole (34) of the core (20) in such a way that a gap (46) is present between the core (20) and the armature (22) when the actuator unit (10) is actuated.
