US 11,027,716 B2 · Integrated solenoid valve and brake system using the same

Abstract

An integrated solenoid valve and a brake system using the same are disclosed. The integrated solenoid valve includes an armature, an elastic member, a magnet core, an orifice unit, a filter member, a lip seal, a bidirectional passage, and a unidirectional passage. The armature is disposed in a sleeve, moves upward and downward in an axial direction, and opens or closes an orifice of a seat disposed at a lower side thereof. The elastic member provides elastic force to the armature in a closing direction of the orifice. The magnet core provides drive force to the armature in a direction opposite to that of the elastic member. The orifice unit is coupled to a lower side of the seat, and includes not only a hollow hole communicating with the orifice of the seat but also a passage hole. The filter member prevents inflow of foreign materials. The lip seal is inserted between the orifice unit and the filter member, and includes an inclined protrusion. The bidirectional passage is opened or closed by the armature moving up and down. The unidirectional passage is formed to pass through the passage hole and an outer surface of the inclined protrusion.

An integrated solenoid valve comprising:

an armature disposed in a sleeve, and configured to move upward and downward in an axial direction, and open or close an orifice of a seat disposed at a lower side thereof;
an elastic member configured to provide elastic force to the armature in a closing direction of the orifice;
a magnet core configured to provide drive force to the armature in a direction opposite to that of the elastic member;
an orifice unit coupled to a lower side of the seat, and configured to include not only a hollow hole communicating with the orifice of the seat but also a passage hole;
a filter member configured to prevent inflow of foreign materials;
a lip seal inserted between the orifice unit and the filter member, and configured to include an inclined protrusion, wherein the lip seal is positioned to directly contact the filter member;
a bidirectional passage opened or closed by the armature moving up and down;
a unidirectional passage formed to pass through the passage hole and an outer surface of the inclined protrusion.
