Claims

[Claims for Utility Model Registration] (1) One end of the main flow path is located on one side of the main flow path of the first body, which has a fluid inlet at one end and a fluid outlet at the other end, the middle part of which is partitioned by a partition wall. A second body having a solenoid valve passage whose other end communicates with the fluid inlet side from the partition wall of the channel and whose other end communicates with the fluid outlet side from the partition wall of the main flow passage is fixed, and a solenoid valve body for opening and closing the solenoid valve passage is fixed. A bypass flow path is formed on the other side of the main flow channel of the first body, one end of which communicates with the fluid inlet side of the main flow channel than the partition wall, and the other end of which communicates with the fluid outlet side of the main flow channel with respect to the partition wall of the main flow channel. A solenoid valve with a bypass valve, characterized in that a manual bypass valve element for opening and closing the bypass passage is provided in the first body. (2) Open upstream and downstream communication ports that communicate with the fluid inlet and outlet sides of the main flow path, respectively, on one side of the first body, and open at a 90° angle with the center of the downstream communication port as the axis. A second body is rotatably fixed to the first body, and a downstream side portion of a solenoid valve flow path provided in the second body that communicates with the downstream side communication port on the downstream side of the solenoid valve body is connected to the downstream side communication port. an upstream side portion that is always in communication with the upstream side communication port on the upstream side of the solenoid valve body of the solenoid valve flow path is arranged on a circle concentric with the center of the downstream side portion;
2. The solenoid valve with a bypass valve according to claim 1, wherein the axial direction of the solenoid valve body is disposed in a direction perpendicular to the axial directions of the upstream and downstream parts of the solenoid valve flow path.
