Solenoid valve, particularly for hydraulic unit, has armature, which is guided movably inside housing for opening and closing main sealing seat and coupled to main sealing element

摘要

The solenoid valve (1) has a housing (2), two connections (3,4), a pole core (5) and an armature (6), and is guided movably inside the housing for opening and closing a main sealing seat (7.1) and coupled to a main sealing element (8). A secondary sealing element (10) is movably guided in a bore (9) and closes and opens a secondary sealing seat (8.1) in the main sealing element. The armature is displaced by an overall displacement (h1) in the direction of opening, together with the secondary sealing element and the main sealing element, when the solenoid is activated in a pressure less state.
