A fluid pressure controlling solenoid valve comprising an intermediate member of a magnetic material having a cylindrical outer side surface and including a first valve seat disposed in its upper end face and located at the center of the cylindrical configuration. A first fluid path is disposed adjacent to the first valve seat and extends from the upper to the lower end face. A second fluid path communicates with the fluid passage of the first valve seat and extends in a direction away from the center. A first end member of a magnetic material has a cylindrical outer side surface and including a second valve seat disposed at the center of the cylindrical configuration and a first port communicating with the fluid passage of the second valve seat. A second end member of a magnetic material has a cylindrical outer side surface and includes a third valve seat disposed at the center of the cylindrical configuration in opposing relationship with the other surface of the intermediate member and a third port communicating with the fluid passage of the third valve seat.
