Document Type and Number:
WIPO Patent Application WO/2024/043582
Kind Code:
A1
Abstract:
A solenoid valve according to an embodiment of the present invention is installed in a valve block to control the flow rate between a first flow path and a second flow path of the valve block. The solenoid valve comprises: a seat member having an orifice; an armature configured to selectively open and close the orifice to selectively form a main flow path connecting the first flow path to the second flow path; a magnet core that provides a driving force to cause movement of the armature; a filter member; and a check valve structure configured to form a one-way auxiliary flow path connecting the first flow path to the second flow path. The check valve structure includes one or more oil passages provided in the filter member, and a lip seal disposed in a space connected to the oil passages. The lip seal is disposed in a space between the filter member and the valve block, to be installed in a state of being supported by the filter member and the valve block.
