Solenoid valve having a structure with less fluid leakage

A solenoid valve comprising:

• a solenoid portion that includes a pin that is movable in an axial direction and that moves the pin to one side in the axial direction by an attractive force generated by excitation, and
• a nozzle portion positioned on one side of the solenoid portion in the axial direction and having a valve body connected to one side of the pin in the axial direction and a nozzle body that houses the valve body;
• wherein the nozzle body includes a cavity which is recessed toward on one side in the axial direction and has an opening on the other side in the axial direction,
• wherein in the nozzle body,
• a valve chamber is provided on the one side of the cavity in the axial direction, and the valve chamber houses the valve body on the one side of the cavity in the axial direction, and
• a solenoid housing portion is provided on the other side of the cavity in the axial direction, and the solenoid housing portion houses the solenoid portion on the other side of the cavity in the axial direction,
• wherein the nozzle portion includes:
• a first port provided in the nozzle body and that communicates with a bottom surface of the valve chamber on one side of the valve chamber in the axial direction,
• a second port that is provided in the nozzle body and that communicates with an inner surface of the valve chamber,
• a valve hole that is provided on the bottom surface of the valve chamber and that communicates with the first port, and
• a spring that is housed in the valve chamber and that urges the valve body toward the other side in the axial direction, and
• wherein, when the solenoid portion is excited, the valve body is driven by the pin, moves to the one side in the axial direction, and closes the valve hole, and when the solenoid portion is not excited, the valve body is urged by the spring, moves to the other side in the axial direction, and opens the valve hole,
• wherein the solenoid portion includes
• a bobbin having a cylindrical shape, the bobbin extending along the axial direction and including a first through hole along the axial direction,
• a coil wounded around a circumferential surface of the bobbin,
• a yoke disposed on the other side of the bobbin in the axial direction,
• a plunger disposed on the other side of the first through hole in the axial direction and fixed to the other side of the pin in the axial direction, and
• a core having a cylindrical shape, the core being disposed on one side of the first through hole in the axial direction and including a second through hole in the axial direction, and
• a mold that covers an outer surface of the coil in a radial direction inside the solenoid housing portion, and
• a seal member provided between the mold and the solenoid housing portion
• wherein the solenoid housing portion houses the pin, the bobbin, the coil, the yoke, the plunger, and the core.
